SKIN CLEANSING COMPOSITION PROVIDING ENHANCED PERFUMED DEPOSITION
Fragrances have been employed in skin care compositions for hundreds of
years. These fra~ances have a number of uses. They provide a recognized aroma
to
the user of the composition or a person in close juxtaposition to that person.
Fragrances mask the odor produced by bacteria growing on the skin. Fragrances
can
IO work as a solubilizing agent for other organic materials in the
composition. However,
not infrequently the effects of fragrances in skin care compositions,
particularly those
of the "rinse-off' type are short lived. Assuming they stay on the skin during
the short
contact time and are not washed off during the skin care process, their
adherence to
the skin may be weak and/or their detachment from the skin occurs at too quick
a rate,
15 thereby leaving no significant odor after a short period of time following
rinse off.
Therefore in order to provide an appropriate fragrance to the head space above
the
skin, there must be a proper combination of quantity of fragrance on the skin,
adhesion to the skin and release from the skin over an appropriate time
period. This
combination will provide a "persistent" odor over a significant period of
time.
A new composition has been discovered which can provide these fraerance
benefits. The composition is a rinse-off cleansing composition which provides
an
improvement in fragrance benefits.
~
In accordance with the invention, there is a method for cleansing the skin and
providing an increased fragrance benefit after rinsing the skin from the
cleansing
composition which comprises, applying to the skin a composition having:
a. one or a mixture of surfactants in sufficient quantity to cleanse
skin;
b. a fragrance in sufficient quantities to provide aroma
c. a silicone or a hydrocarbonaceous component or mixtures
thereof in sufficient quantities to bring about increased
fragrance benefits
and rinsing off said composition.

DETAILED DESCRIPTION OF TH INVENTION
By fragrance is meant any volatile perfume agent which provides an aroma to
the final composition in which the fragrance residues. Examples of such
materials are
those boiling at temperatures below about 500°C. The highly volatile,
low boiling,
perfume ingredients typically have boiling points of about 250°C or
lower. The
moderately volatile perfume ingredients are those having boiling points of
from about
250°C to about 300°C. The less volatile. high boiling, perfume
ingredients are those
having boiling points of about 300°C to about 500°C. Many of the
perfume
ingredients as discussed hereinafter along with their odor and/or flavor
characters, and
their physical and chemical properties, such as boiling point and molecular
weights

The preferred surfactant is an anionic surfactant such as soap,
alkylisethionate
such as sodium cocoylisethionate, a sulfonate, a sulfate (optionally
ethoxylated) and
the like. Mixtures of surfactants can be employed. There should be sufficient
surfactant present to bring about a cleansing effect. The surfactant
preferably anionic

or mixtures thereof involving one or more from the other families of
illustrated
surfactants (amphoteric, nonionic and the like) with or without an additional
anionic _
surfactant, can be present in the composition in various quantities. For
example
broad minimums of the surfactant can be present at l, 2, 3, 4, S, 10, 1 S or
20 wt.% of
S the compositions, particularly where the aqueous composition is a liquid.
With
respect to liquid, aqueous, compositions, the anionic surfactant is from about
2 to
about 2S wt.% of the composition, specifically about S to about 20 wt.%. Other
surfactants may be present such as an amphoteric, particularly a betaine, and
a
nonionic, particularly an alkylated polyglycoside. Their quantities are from
about 1
to about 20 wt.% of the composition. Generally the total surfactant in a
liquid
composition is at least about 3 or 4 wt.%, preferably at least about S wt.%
and is
generally no more than about 30 wt.%, preferably no more than about 2S wt.%
but
can be as low as more than about 10, 1 S or 20 wt.%. For a solid composition,
the
total surfactant can be from about 60 to about 90 wt.%, preferably from about
70 to
1S about 8S wt.%, of the composition. Soap can be present at about 1S to about
100
wt.% of the total surfactant. "Soap-bars" generally have from about 6S to
about 90
wt.% saap therein with less than about 10 wt.%, preferably less than about S
wt.% of
other surfactant therein. Most preferably, there is zero or zero to about 2
wt.% of
other surfactant therein Bars having a smaller quantity of soap within the
disclosed
range of soap usually have a mild synthetic surfactant therein such as sodium
cocoyl
isethionate at moderate to high levels.
If present, the quantity of hydrocarbonaceous component should be at least
about 0.1, preferably from about O.S wt.% of the composition. Although about 7
or 8
2S wt.%, of the material can be employed, it is preferred to have a maximum of
about S
wt.%, preferably about 4.S wt.% of the composition. If a silicone is present
in the
composition, the minimum quantity is about 0.01 wt.% of the composition,
preferably at least about 0.1 wt.%. The maximum can vary but generally is not
above
about 7 or 8 wt.%, preferably about S wt.%, more preferably about 4.5 wt.% of
the
composition.

When using a cationic polymer in the composition, the quantity of polymer is
from about 0.01 to abut 3.Owt.% of the composition preferably about 0.02 wt.%
as a _
minimum and more preferably about 0.03 wt.% as a minimum. The maximum is
generally no more than about 0.9 wt.%, or about 0.75wt.%, although lower
maximums such as about 0.6wt.% can be employed.
The form of the composition can be liquid, solid or gel. The solids can be
formulated into a "bar" which can be hand gel for cleansing purposes. The
liquids can
be formulated with such viscosities that are pourable from containers or
expelled by a
hand activated pump, for example.
Fragrance benefits, used in this specfication, can include enhanced deposition
on skin, extended release of fragrance from the skin, selective deposition on
skin of
specific compounds associated with providing an aroma, and the like. The
fragrance
should be present in quantities to provide an aroma. Generally, at least about
0.01
wt.%, preferably at least about 0.1 wt.% of the composition is a fragrance. A
maximum quantity is generally dependent upon the strength and quantity of
aroma
desired. Usually not more than about 2 wt.%, preferably not more than about
1.5
wt.% of the composition of fragrance is employed.
