Foamable or sprayable hair styling product with polyalkoxylated silicone
esters
The object of the invention is a hair styling product that comprises a
foamable or
sprayable, gel-type emulsion and a device for spraying or foaming the
emulsion, wherein the
emulsion contains esters of polyalkoxylated polydimethylsiloxanes, gelling
agents or thickeners,
emulsifiers and water.
Hair waxes are known hair treatment products. In particular, they can be used
in order to
provide a trendy shape to hair that is from short to middle length, and to
lend hold, body,
cohesiveness and shine to hair styles. Hair waxes also allow contours and
textures to be produced
in the hair style. The hair has a characteristic sensation by touch, a typical
"waxy feel", and since
it possesses a persistent residual tackiness, the resultant restyling
potential is a typical property of
hair wax. Conventional hair waxes have a wax-like solid consistency and are
usually offered in
tubs. The following procedures are employed for their use: A quantity of the
product is taken up
with the fingers. A wax that is a solid at room temperature is spread over the
palms of the hand,
and is melted or at least significantly softened by the heat of the hands and
by friction. This
softening or melting enables the otherwise solid wax to be worked into the
hair. In this softened
or more or less liquid state, the wax is worked into the hair. Once in the
hair, it cools and resumes
its original solid consistency. In this way, the wax solidifies and the hair
style that has been
prepared will possess stability, hold, a typical waxy feel as well as an often
slightly wet
appearance. These procedures set narrow limits on the product performance for
conventional
styling wax products. In order to permit the wax to be worked into the hair
readily, it should not
be too hard when taken up into the hand, and the melting or softening point
must be in the
vicinity of body temperature. Otherwise, soft waxes of this type will only be
able to achieve a
moderate level of product performance with respect to the condition of the
hair, and the hold and
volume of the hair style. Nevertheless, the stress on the hair is
comparatively high. A harder wax
composition makes it possible to obtain much better cohesiveness and better
hold, but the harder
the wax, the harder will be the portion of the product that is used, and
consequently the more
difficult it will be to work with and to work into the hair. With a wax
product in a tub, there are
generally problems with poor dosability, conflicting requirements concerning
the hardness of the
wax product and the experience of the wax product having a disagreeable feel
while it is being
CA 02587086 2007-04-16
2
worked into the hair. Moreover, conventional products such as hair wax, wax
foams, spray waxes
or styling foams are not yet completely satisfactory in their current form,
particularly with regard
to their application, and the strength and duration of their tackiness phase
while still providing
optimal styling potential.
The goal is to develop a product that exhibits the typical product performance
of a solid
hair wax, e.g. that provides the hair style with improved hold, body and a
typical waxy feel, and
enables the restyling potential that is characteristic of hair wax and imparts
to the hair a natural,
semi-matte shine, while at the same time exhibiting a satistfactory tackiness
phase, is readily
spread and worked into the hair, can guarantee simple and clean handling,
elicits innovative and
positive associations in the user, presents a pleasing feel when being worked
into the hair and is
readily washed out.
The object of the present invention is a hair styling product that possesses a
foamable or
sprayable, gel-type emulsion and contains
(A) at least one silicone compound, selected from among the esters of
polyalkoxylated
polydimethylsiloxanes,
(B) at least one gelling agent or thickener,
(C) at least one emulsifier and
(D water
in combination with a device for spraying or foaming the composition and their
use for
conditioning and/or for styling of human hair.
Foamable compositions are compositions from which a foam that is stable at
least
temporarily (e.g. at least 30 seconds) can be formed by means of suitable
devices for foaming,
such as e.g. foam pumps or aerosol containers with a foaming head. Sprayable
compositions are
compositions from which a spray that has a sufficiently small droplet size
(e.g. mean droplet size
preferably smaller than 150 m, particularly smaller than or equal to 100 m)
can be formed by
means of suitable spraying devices such as e.g. spray pumps or aerosol
containers with a spraying
head. A gel-type emulsion can, for example, have a fluid consistency (liquid
gel). As a rule, gel-
type compositions are different from liquids in that they exhibit elastic
properties, in other words
the elastic component of the storage modulus (elastic modulus) G' exceeds the
value of the loss
modulus G". At room temperature (25 C (77 F)), G' is larger than G" in least
in one portion of
the region (e.g. at 20 Hz), preferably in the entire region of normal
measurement frquencies such

Formulations for application
One embodiment of the hair styling product of the present invention relates to
an aerosol
or non-aerosol foam product (mousse) together with a suitable device for
foaming. The emulsion
is thus foamable, in other words it contains at least one conventional,
heretofore known foam-
generating substance, e.g. at least one foam-producing surfactant and/or at
least one foam-
producing polymer. Devices for foaming are understood to be devices that
enable the foaming of a
liquid either with or without the use of an aerosol propellant. As a suitable
mechanical foaming
device, for example a commercially available foam pump or an aerosol foaming
head can be used.
A(foam pump) that is a non-aerosol foaming product will possess a mechanical
pump foaming
device. A aerosol foaming product will possess at least one aerosol
propellant, a pressure-proof
container and a device for foaming in the form of a foaming head. The aerosol
propellant can be
contained for example in an amount of from 1 to 20, from 2 to 15 or from 5 to
10 percent by
weight. The aerosol propellant can be selected for example from among propane,
butane,
dimethylether and fluorinated hydrocarbons (e.g. 1,1-difluorethane). Carbon
dioxide may also be
utilized either alone or in combination with other propellants. Propane,
Butane and mixtures
CA 02587086 2007-04-16

pump-spray product and comprises a mechanical pump spraying device. The
emulsion can be
sprayed by means of a suitable mechanically driven spraying device. A
mechanical spraying
device is understood to be a device that enables the spraying of a composition
without the use of a
aerosol propellant. As suitable mechanical spraying devices, for example, a
spray pump or an
elastic container with a spray valve can be used, which would be filled under
pressure with a
cosmetic agent of the present invention, during the process of which the
elastic container will
undergo expansion so that the agent will be continuously expelled from the
elastic container by
contraction of same when the spray valve has been opened.

anionizable groups,
or cationic polymers, in other words polymers with cationic or cationizable
groups, or

triethanolamine or
monoethanolamine, and also ammonia, NaOH, KOH among others.
The anionic polymer can be a homo- or copolymer with acid group-containing
monomer
units derived from natural or synthetic sources, which if necessary can be
polymerized with
comonomers that contain no acid groups. Among the acid group that can be

known
procedures. A review of modem procedures for the preparation of semisolid and
liquid emulsions
can be found in the article in the SOFW-Journal, Volume 124 (5/98), pp 308-313
as well as in the
article in the SOFW-Journal, Volume 118. (5/92) pp 287-296. As a rule, the
preparation of the
CA 02587086 2007-04-16
18
emulsion takes place in such a manner that the hydrophobic phase is heated to
about 60 to 75 C
(140 to 167 F) and the solid waxy substances are melted. Thickeners, gelling
agents and if
necessary styling polymers are swollen or dissolved in the aqueous phase and
are likewise
warmed to about 60 to 75 C (140 to 167 F). The hot premixtures are combined
and
homogenized with a mixer or homogenizer. Temperature-sensitive or volatile
components are
added after cooling to about 30 to 40 C (86 to 104 F). Following this, the
completed emulsion is
cooled to ambient temperature. Aerosol products are charged for example with
from 5 to 10
percent by weight of propane/butane or dimethylether.
The products of the present invention can be used on both dry and moist hair,
and
disperse well into the hair. Hair that is treated with the products of the
present invention will
exhibit a pleasing waxy feel after drying, have the potential for restyling
and above all will have
good combability with moist hair when compared with conventional hair wax
products.
Moreover, the products are readily washed out at a later time. The foam
produced by the foam
products of the present invention is characterized by an especially pleasant,
creamy feel during
use when compared with conventional aerosol styling foams or hair conditioning
foams.
With the cosmetic agent of the present invention, the quantity used will
depend upon the
amount and condition of the of hair to be treated and will be a quantity
sufficient to obtain the
desired hair styling effect (typically about 3 - 10 g), and is applied to the
washed hair as a foam or
spray and is spread in. Preferably the agent remains in the hair and becomes
dry after use. The
object of the invention is thus also a method for hair treatment, wherein
- by means of the above-described product of the present invention, a
composition is first
applied to the hand either as a spray or as a foam and is spread into the hair
by hand, or
is applied directly to the hair as a spray or a foam and is then spread in by
hand, where
said product can be used either on freshly washed, moist hair or on dry hair;
- the composition applied to the hair is allowed to remain in the hair and
- then the desired hair style is produced.
The product of the present invention can be used in particular for the
conditioning and/or
for the styling of human hair.
The following examples should serve to illustrate further the object of the
present invention.

The preparation is carried out by melting the wax phase together with the oil
components;
swelling and dissolution of the thickeners and styling polymers in the aqueous
phase; combining
of the hot premixtures and homogenization, followed by addition of the
temperature-sensitive or
volatile components at about 35 C (95 F). For aerosol foams, the emulsions
are charged with
about 5-10% of propane/butane or dimethylether in pressure-proof containers
with a foaming
head. For pump sprays, the emulsions are packaged in suitable containers with
spray pumps.
The aerosol foam is characterized by a unique foam quality. After being drawn
out of the
pressurized container, it develops into a visually pleasing foam. While being
spread into
CA 02587086 2007-04-16
the hair with the hands, it promptly develops into a creamy consistency that
is spread
readily. This material is optimally suited for spreading through the hair.
Immediately
after application, the product exhibits a high degree of tackiness in the
hair, which
improves the styling properties as compared with conventional styling waxes,
foam
5 waxes and foam setting preparations. The tackiness subsides automatically
with
increasing dryness, and the hair takes on a dry, waxy feel without having a
greasy shine.
The product provides the hair with excellent stability and very good styling
properties.
