PROCESS FOR MAKING NON-UNIFORM PATTERNS OF MULTIPHASE
COMPOSITIONS
FIELD OF THE INVENTION
The present invention relates to a process for making non-uniform patterns in
personal
care compositions with multiple visually distinct phases.
BACKGROUND OF THE INVENTION
In an increasingly competitive commercial market, it is becoming more and more
difficult for manufacturers to distinguish products from those of their
competitors. Therefore, it
is desirable for products not'only to appear aesthetically pleasing to
consumers, but also for the
products to have a substantially unique appearance from other products in the
same market.
In the case of compositions having multiple visually distinct phases, various
attempts
have been made to create such compositions and to improve known processes for
their creation.
Processes and apparatuses are known which allow compositions having two or
more visually
distinct phases to be filled with a spiral configuration into a single
container. Each phase may
have completely different chemical and physical properties, and each product
may have a
different function and purpose. Alternately, the visually distinct phases may
be substantially the
same compositions with only differences in color or texture. Known processes
for filling one or
more compositions, having two or more visually distinct phases, result uniform
patterns.
An attempt at filling spiral compositions involves providing at least two
compounds,
arranged in separate storage bins each having a pump and a hose attached
thereto; rotating a
container, for receiving a resulting product formed by the at least two
compositions, into
position relative to a support and alignment funnel. Then the compounds are
pumped through
the respective hoses into a nozzle assembly having at least two nozzles for
filling the container.
Subsequently, predetermined amounts of each of the at least two compositions
are combined for
creating the resulting product housed in a single container, wherein the
resulting product has the
at least two compositions formed in a spiral configuration.
A drawback of each of the aforementioned processes is that none of them
provide a
means for filling. personal care compositions having non-uniform patterns into
a container. It is
desirable, especially for commercial products, to have the latitude of
exhibiting as many designs
as possible by implementing an economical and efficient process. Therefore,
there is a need for
a method of filling personal care compositions having non-uniform patterns
into a container.

SUMMARY OF THE INVENTION
The present invention relates to a process for making non-uniformed patterned
multi-
phase liquid compositions that comprise at least two visually distinct liquid
phases. The process
comprises the steps of:
a) placing a plurality of liquid phases in separate vessels equipped with
means for
transferring said phases from said vessels;
b) transferring predetermined amounts of each selected liquid phase from its
respective vessel into a combiner;
c) combining said liquid phases together to produce a multi-phase liquid
composition
having predetermined ratios of one phase to another wherein said phases of the
liquid composition are visually distinct from one another; and
d) transferring said multi-phase liquid phase composition through a dispensing
means
to an individual product container; wherein said individual product container
enters
a bottle holding device, therein securing said container to a rotating
platform
wherein said container is rotated using said rotating platform during transfer
of said
composition into said container, wherein said dispensing means has an initial
fill
rate, said holding device has an initial speed of rotation, and wherein said
holding
device has an initial direction of rotation; and
e) changing an element selected from the group consisting of said initial
direction of
rotation, said initial speed of rotation, said fill rate of said dispensing
means, and
mixtures thereof, independently from the geometry of said container.
According to one embodiment, during filling, the direction of rotation of the
container,
the speed of rotation, or the fill rate changes from one speed to another to
create non-uniform
patterns. For example, during filling, the direction of rotation may be
changed once or multiple
times during filling to achieve a non-uniform pattern. The direction of
rotation could oscillate in
some embodiments, back and forth to achieve a desirable pattern. Additionally,
during filling, the
speed of rotation may be changed, for example, from 2 rpm to 40 rpm or the
fill rate may be
changed from 100 ml/s to 20 ml/s. Alternately, both the fill rate and the
speed of rotation may be
changed in order to create non-uniform patterns. Generally, the fill rate is
greater than 0 ml/s
from the time between the commencement of filling until filling is completed.
Therefore,
cessation of filling is not considered to be a "change in fill rate" according
to this invention. It
has been discovered that changes in the direction of rotation, speed of
rotation of the container or
CA 02671404 2009-06-02
WO 2008/073302 PCT/US2007/025092
3
changes in fill rate, during filling, enables a wide variety of designs and
patterns to be created in
the composition.
In one embodiment, the visually distinct phases only differ in color, texture,
or mixtures
thereof. Differences in color may include entirely different colors (i.e., a
red phase and a blue
phase) or differences in color shades (i.e., a royal blue phase and a light
blue phase). Specific
patterns can be chosen from a wide variety of patterns, including, but not
limited to striping,
marbling, geometrics, spirals, and mixtures thereof. Upon changing either fill
rate, speed of
rotation, or both, the aforementioned patterns visually appear to be non-
uniform. For example, a
non-uniform swirled composition may change such that stripes appear to be
close to one another
at the base of the container, and then appear to spread further from one
another towards the top of
the container as a result of changing speed of rotation, fill rate, or both.

The term "personal care composition" as used herein, refers to compositions
intended for
topical application to the skin or hair. The compositions of the present
invention are rinse-off
formulations, in which the product is applied topically to the skin or hair
and then is
subsequently rinsed within minutes from the skin or hair with water, or
otherwise wiped off
using a substrate with deposition of a portion of the composition. The
compositions also may be
used as shaving aids. The multiphase personal care composition of the present
invention is
typically extrudable or dispensible from a package. The multiphase personal
care compositions
typically exhibit a viscosity of from about 1,500 centipoise (cP) to about
1,000,000 cP, as
measured by as measured by the Viscosity Method as described in the commonly
owned, patent
application published on Nov. 11, 2004 under U.S. Publication No.
2004/0223991A1 entitled
"Multi-phase Personal Care Compositions" filed on May 7, 2004 by Wei, et al.
The multiphase
personal care compositions of the present invention can be in the forrn of
liquid, semi-liquid,
cream, lotion or gel compositions intended for topical application to skin.
Examples of personal
care compositions of the present invention can include but are not limited to
shampoo,

cleansers,
cleansing milks, hair and body wash, pet shampoo, shaving preparations and
cleansing
compositions used in conjunction with a disposable cleansing cloth.
As used herein, the term "phase" as used herein refers to a homogeneous,
physically
distinct, and mechanically separable portion of matter present in a non-
homogeneous physical-
chemical system. Phases may be materials considered an intermediate and or a
finished product.
In one aspect, the phases herein are compositions with different colors. In
one aspect, the phases
comprise the same chemical compositions but with different colorants and/or
rheology
modifiers. The phases can be various different colors, and/or include
particles, glitter or
pearlescent agents in at least one of the phases in order to offset its
appearance from the other
phase(s) present. The ratio of a first phase to a second phase is preferably
from about 90:10 to
about 10:90, more preferably from about 80:20 to about 20:80, even more
preferably from about

70:30 to about 30:70, still even more preferably from about 60:40 to about
40:60, even still even
more preferably about 50:50.
The term "speed of rotation" as used herein, refers to the speed at which a
container turns
about an axis, typically measured in rotations per minute (rpm). Generally,
the container rotates
as a result of the rotation of a platform as depicted in Fig. 3.
The term "stripe" as used herein, means that each phase present in the
composition
occupies separate but distinct physical spaces inside the package in which it
is stored, but are in
direct contact with one another. In one preferred embodiment, a personal care
composition
comprises a cleansing phase and a benefit phase that are present within the
container as distinct
layers or "stripes". The stripes may be relatively uniform and even across
segments of the
package. Alternatively the layers may be uneven, i.e. wavy, or may be non-
uniform in
dimension. The stripes do not necessarily extend across the entire dimension
of the package.
The "stripe' can comprise various geometric patterns, various colors and, or
glitter or
pearlescence, providing that the concentration of said alternative forms
visually distinct bands or
regions. The striped pattern does not need to necessarily extend across the
entire dimension of
the package. The size of the stripes can be at least about 0.1 mm in width and
10 mm in length,
preferably at least about 1 mm in width and at least 20 mm in length as
measured from the
package exterior.
The term "stable" as used herein, unless otherwise specified, refers to
compositions that
maintain visually distinctive phases in physical contact at ambient conditions
for a period of at
least about 180 days.
The phrase "substantially free of' as used herein, unless otherwise specified
means that
the composition comprises less than about 5%, preferably less than about 3%,
more preferably
less than about 1% and most preferably less than about 0.1 % of the stated
ingredient. The term
"free of' as used herein means that the composition comprise 0% of the stated
ingredient that is
the ingredient has not been added to the composition, however, these
ingredients may
incidentally form as a byproduct or a reaction product of the other components
of the
composition.
The term "surfactant component" as used herein means the total of all anionic,
nonionic,
amphoteric, zwitterionic and cationic surfactants in a phase. When
calculations are based on the
surfactant component, water and electrolyte are excluded from the calculations
involving the
surfactant component, since surfactants as manufactured typically are diluted
and neutralized.

As used herein "tottle" refers to a bottle which rests on neck or mouth which
its contents
are filled in and dispensed from, but it is also the end upon which the bottle
is intended to rest or
sit upon (e.g., the bottle's base) for storage by the consumer and/or for
display on the store shelf
(this bottle is referred to herein as a "tottle"). Typically, the closure on a
tottle is flat or concave,
such that the tottle, when stored, rests on the closure. Suitable tottles are
described in the co-
pending U.S. Patent Application Serial No, 11/067443 filed on Feb. 25, 2005 to
McCall, et al,
entitled "Multi-phase Personal Care Compositions, Process for Making and
Providing, and
Article of Commerce."
As used herein, "visually distinctive" or "visually distinct" describes
compositions in the
package or upon being dispensed that display visually different phases. These
different phases
are either distinctively separate or partially mixed as long as the phases of
the multiphase liquid
composition remains visible to the unaided eye. That is, a region of the
multiphase liquid
composition has one average composition, as distinct from another region
having a different
average composition, wherein the regions are visible to the unaided naked eye.
In one aspect,
the phases may be various different colors, and/or include particles, glitter
or pearlescent agents
in at least one of the phases in order to offset its appearance from the other
phase(s) present.
This would not preclude the distinct regions from comprising two similar
phases where one
phase could comprise pigments, dyes, particles, and various optional
ingredients, hence a region
of a different average composition. A phase generally occupies a space or
spaces having
dimensions larger than the colloidal or sub-colloidal components it comprises.
A phase can also
be constituted or re-constituted, collected, or separated into a bulk phase in
order to observe its
properties, e.g., by centrifugation, filtration or the like.
The present invention relates to a process for making non-uniformed patterned
multi-
phase liquid compositions that comprise at least two visually distinct liquid
phases. The process
comprising the steps of:
a) placing a plurality of liquid phases in separate vessels equipped with
means for
transferring said phases from said vessels;
b) transferring predetermined amounts of each selected liquid phase from its
respective vessel into a combiner;
c) combining said liquid phases together to produce a multi-phase liquid
composition having predetermined ratios of one phase to another wherein said
phases of the liquid composition are visually distinct from one another; and
CA 02671404 2009-06-02
WO 2008/073302 PCT/US2007/025092

d) transferring said multi-phase liquid phase composition through a dispensing
means to an individual product container; wherein said individual product
container enters a container holding means, therein securing said container to
a
platform wherein said container is rotated by said container holding device
during
transfer of said composition into said container, wherein said dispensing
means
begins dispensing said liquid phases at an initial fill rate, said holding
device has
an initial speed of rotation, and wherein said holding device has an initial
direction of rotation; and
e) selecting a modification to an element selected from the group consisting
of
modifying said initial direction of rotation to a second direction of
rotation,
modifying said initial speed of rotation to a second speed of rotation,
modifying
said initial fill rate of said dispensing means to a second fill rate, and
mixtures of
said modifications, independently from the geometry of said container and
during
step d.
Various devices are known for filling multiple phase compositions. Figure 1
illustrates a
perspective view of one device which may be used to make the multiple visually
distinct phase
compositions of the present invention and fill the packaging into which it
will be sold. This
figure represents a single filling station. On a manufacturing scale this
alignment of equipment
is repeated for as many filling stations as is desired for simultaneously
filling of a plurality of
containers. Supply lines 1 and 2 are in communication with each phase's supply
vessel, not
illustrated herein. Said supply lines 1 and 2 can be in the fonm of hard or
flexible piping such as
stainless pipes or hoses, useful in transporting said phases from their
respective supply vessels.
Such supply vessels are typically stainless steel and are equipped with valves
at their base
wherein flow can be shut off to allow for changing such vessels without
shutting down the
processing equipment. Said supply lines may be equipped with an inline pump
from the supply
vessel, thereby pressurizing the supply line to ensure consistent or steady
flow from its
connected supply vessel. Figure 1 illustrates a situation wherein supply line
1 is hard plumbed
with an in-line pump not shown, whereas supply line 2 is not under pressure
and the respective
visually distinct phase feeds from the supply vessel into the funnel shown
therein. Supply lines
1 and 2 lead to valves 5 that regulate flow of each phase to its respective
pump, in this
illustration, pumps 3 and 4. In Figure 1 the pumps are illustrated as positive
displacement,
piston-type cylinders. Valves 5 are rotary valves that open to allow the flow
of each phase from
CA 02671404 2009-06-02
WO 2008/073302 PCT/US2007/025092
its supply vessel to enter the pump's cylinder as the pump piston is in its
back or down stroke.
There is a single valve for each pump and all the valves act in unison due to
their being linked in
a manner wherein one drive mechanism actuates all the valves. Alternately,
separate drive
mechanisms can be used to achieve a similar effect. Simultaneously to the flow
entering the
piston cylinders, valves 5 close the outlet of said cylinders to prohibit the
phase from flowing
directly into supply lines 3a and 4a going to combiner 6. Upon the pumps
forward or upstroke,
valves 5 reverse position, allowing the contents of each pump cylinder to
discharge its contents
into the direction of the combiner 6 through supply lines 3a and 4a while
prohibiting back flow
into the vessel supply lines 1 and 2. Pumps 3 and 4 are used to insure a
constant supply of each
phase to the combiner section 6. Given the proper flow character of the phase,
such piston type
pumps may be eliminated. When pumps are utilized, it is preferable that said
pumps work in
tandem with flow meters to insure consistent flow by the pump. Not illustrated
herein,
volumetric flow meters, and, or mass flow meters can be utilized to adjust the
pumps to insure
constant flow. This can also be accomplished by utilizing metering type pumps
to deliver the
required volume or mass of each phase.
Prior to the phases entering the blender 7, the supply lines 3a and 4a are
aligned in such a
manner as shown in the cross-sectional views of Figure 2 in the combiner
section 6. Figure 2
represents a cross-sectional view of the alignment of the phase feeds from
line 3a and 4a as they
are prepared for entering blender 7. Figure 2a illustrates an alignment of
feeds from 3a and 4a
wherein independent feed line 21 is located within feed line 22, thereby
injecting the phase
coming from 21 into the center of the feed from line 22 prior to going into
the blender 7. Figure
2c is an alternative to figure 2a where the feeds are aligned side by side in
a common line from
the combiner section 6. Figure 2b similarly illustrates the situation where
four feeds are
combined together in one line coming from the combiner section 6 going to
blender 7.
In some embodiments, the process can further comprises the steps of
transferring
said liquid phases from the combiner to the blender and blending the liquid
phases. After
moving through the combiner section 6, the aligned phases are introduced into
a blending
section 7. The blender section 7 comprises a mixing element that comprises a
series of
obstructions for diverting the visually distinct phases entering, inducing
turbulence and causing
the phases to blend together in a way that contributes to forming the
composition's eventual in-
package pattem. In most cases a static mixer is utilized in the blending
section. Static mixers
are well know in the art and are generally in the form of a series of
repeating or random,
CA 02671404 2009-06-02
WO 2008/073302 PCT/US2007/025092
11
interlocking plates and, or fins. Static mixers suitable for use in the
process are the Chemineer
SSC.75-4R-S (KMA 4 element'/o") available from Chemineer Inc. P.O. Box 1123,
Dayton, OH
45401 and the Koch SMX 4 element mixer (3/4" nominal) available from Koch-
Glitsch LP
Mass Transfer Sales and Engineering, 9525 Kenwood Road, Suite 16-246,
Cincinnati, OH
45242.
After the blended phases pass through blender section 7, the phases are
introduced to the
delivery nozzle 8. Delivery nozzle 8 is utilized to deliver the combined
phases to the bottle. As
previously mentioned, in normal manufacturing operations, a plurality of
containers is filled
simultaneously. Figure 3 represents one possible station on such equipment.
Container 31 is
secured into a puck or bottle holder 32. A rotating platform 33 turns the
container 31 at a speed
determined by the drive mechanism 34. The drive mechanism 34 for the platform
33 is a
variable speed mechanism.
In one embodiment, during filling, the platform 33 rotates, which may
initially rotate the
container 31, in one direction initially. The direction of rotation can change
from the starting
position by any degree of 360 and back to the initial starting position. For
example, the rotation
can occur in one direction by 45 and in the opposite direction returning to
the starting position
of the rotation. However, the returning to the starting position is
unnecessary. For example, the
bottle can be rotated 90 in one direction and rotated back in the opposite
direction by 180 .
Before the container 31 is full, the platform 33 can change in direction one
or more
times, which results in variation in the aesthetic pattern or design of the
multiple visually distinct
phase composition. Designs and patterns created in the personal care
composition depend on
when and to what amount, during the filling process, as the direction of
rotation of the container
31 changes. The direction change of the rotation of the platform 33 and
container 31 can be
controlled by moving the platform by hand or is accomplished using a
servocontroller.
In one embodiment, during filling, the platform 33 rotates, which may
initially
rotate the container 31, at a substantially constant speed. Before the
container 31 is full, the
platform 33 accelerates or decelerates, which results in variation in the
aesthetic pattern or
design of the multiple visually distinct phase composition. Designs and
patterns created in the
personal care composition depend on when and to what amount, during the
filling process, the
speed of rotation of the container 31 changes. The initial speed of rotation
of the container 31 is
generally from about 0 revolutions per minute to about 800 revolutions per
minute (rpm). In
some embodiments, the process further comprises the step of changing the
initial speed of
CA 02671404 2009-06-02
WO 2008/073302 PCT/US2007/025092
12
rotation to second speed of rotation. The second speed of rotation differs
from the initial speed
of rotation by at least 20%. Preferably, the speed of rotation changes by at
least about 20%,
more preferably by at least about 40%, and most preferably by at least about
50% of the initial
speed of rotation. When the initial speed of rotation is 0 revolutions per
minute, initiation of
rotation at any speed during filling is considered to be a change in speed of
rotation.
Additionally, the speed of rotation may change continuously during filling to
create a
continuously changing pattern or design in the composition. The changing
initial speed of
rotation can comprise a acceleration or deceleration which occurs from an
initial speed of
rotation to a second speed of rotation. The acceleration/deceleration can
affect or change the
pattern resultant end product. For example, if there is a quick
acceleration/deceleration, the
resultant fill pattern may have a sharp transition. Conversely, a slower
acceleration/decleration
may cause a smoother transition in the resultant fill pattern.
Herein, changes in fill iate and/or speed of rotation are measured in terms of
percent
change. Changes in fill rate and/or speed of rotation are based on the initial
fill rate and/or
speeds of rotation (i.e., the fill rate and/or speed of rotation measured
prior to changing the fill
rate and/or speed of rotation during filling of the container) and the final
fill rate and/or speed of
rotation (i.e., the fill rate and/or speed of rotation measured either when
the fill rate and/or speed
of rotation reach(es) a new constant speed or just prior to completion of the
filling process). A
percent change is calculated based on the difference between the
aforementioned initial fill rate
and/or speed of rotation and the final fill rate and/or speed of rotation.
In another embodiment, the speed of rotation remains relatively constant and
the fill rate
changes. Preferably, the fill rate changes by at least about 20%, more
preferably by at least
about 40%, and most preferably by at least about 50% of the initial fill rate.
The fill rate may
also change continuously during filling to create a continuously changing
pattern or design in
the compositions
Known filling techniques often incorporate containers which tend to
geometrically
narrow towards an orifice. When filling through such an orifice, in order to
prevent overflow
and to maintain uniformity, either the speed of rotation or fill rate must be
adjusted as the
composition fills towards the orifice. In contrast to this known technique,
the present method
creates non-uniform, visually distinct patterns, by changing the fill rate or
speed of rotation
independently from the geometry of the container.

Additionally, known methods of filling containers generally include filling
the container
with a liquid product by positioning the dispensing means at or near the
orifice of the container.
In the process of present invention, the dispensing means may be arranged in
such a manner as
to position the dispensing means in the bottom of the container. More
specifically, the
dispensing means may be positioned below half of the volume of the container.
Positioning the
dispensing means in this position has the advantage of avoiding the "mounding"
effect exhibited
by filling techniques which employ a dispensing means at or hear the orifice
of the container.
Mounding may generally be described as the layering or folding of a liquid
stream over itself as
the container fills. Accordingly, one aspect of this invention is to fill the
container with the
multiphase liquid phase composition from the bottom of the container.
The transfer of the predetermined amounts of each selected liquid phase from
its
respective vessel into a combiner is accomplished using a servocontroller. //
Add information//
Container 31 is any suitable container for the product. Preferably, container
31 is a
transparent bottle wherein the pattern of the finished composition is visible
to the consumer.
The container preferably comprises a closure and a dispensing orifice.
Suitable materials for
transparent bottles include, but are not limited to PET or PP.
All percentages, parts and ratios as used herein are by weight of the total
composition,
unless otherwise specified. All such weights as they pertain to listed
ingredients are based on
the active level and, therefore, do not include solvents or by-products that
may be included in
commercially available materials, unless otherwise specified.
In one embodiment, the process is used to produce a cleaning compositions,
personal
care composition, dentifrice compositions, having a non-uniform, spirally
striped, patterns. In
some embodiments, one phase can provide one function, such as a cleansing
phase, and the
second phase can provide an additional function, such as a benefit function.
In some
embodiments, the phases can provide the same function but be visually distinct
from each other.
Compositions have been formulated which allow both a cleansing phase and a
benefit phase
which can comprise a variety of phase types while remaining stable for
prolonged periods.
Further, one or more of the phases can include stable colorants, resulting in
the possibility of
non-uniform visual patterns when the personal care compositions are packaged
in containers
which allow the contents to be viewed.

The balance between the hydrophilic and lipophilic moieties in a surfactant
molecule is
used as a method of classification (hydrophile-lipophile balance, HLB). The
HLB values for
commonly-used surfactants are readily available in the literature (e.g., HLB
Index in
McCutcheon's Emulsifiers and Detergents, MC Publishing Co., 2004). For
example, cocamide
monoethanolamine (CMEA) is known in the art to have an HLB value of 16.8.
Another way of
obtaining HLB values is to estimate by calculations. The HLB system was
originally devised by
Griffin (J. Soc. Cosmetic Chem., 1, 311, 1949). Griffin defined the HLB value
of a surfactant as
the mol % of the hydrophilic groups divided by 5, where a completely
hydrophilic molecule
(with no non-polar groups) had an HLB value of 20. Other examples of how to
calculate HLB
values are described by Davies in Interfacial Phenomena, 2nd Edition, Academic
Press,
London, 1963 and by Lin in J. Phys. Chem. 76, 2019-2013, 1972.
Non-limiting examples of preferred nonionic emulsifiers for use herein are
those selected
