Description
TECHNICAL FIELD
[0001] The invention is in the field of cosmetic compositions
applied to the skin or hair.
BACKGROUND OF THE INVENTION
[0002] Cosmetic compositions are generally defined as compositions
suitable for application to the human body. Cosmetic compositions
such as creams and lotions are used to moisturize the skin and keep
it in a smooth supple condition. Pigmented cosmetic compositions
such as makeup, blush, lipstick, and eyeshadow, are used to color
the skin and lips. Since color is one of the most important reasons
for wearing cosmetics, color containing cosmetics must be very
carefully formulated to provide maximum wear and effect.
[0003] One of the long standing problems with makeups such as face
makeup, lipstick, mascara, and the like, is the tendency of the
cosmetic to blot or transfer from the skin or lashes onto other
surfaces such as glassware, silverware, or clothing. This not only
creates soiling, but forces the cosmetic user to reapply cosmetic
at fairly short intervals.
[0004] For example, traditional makeup compositions are either
water and oil emulsions containing pigments, or they can be
anhydrous systems containing waxes, oils and pigments. These
formulations are applied and blended into the skin to provide color
and correct skin topography to provide an even, smooth appearance.
The films are simply deposited on the surface of the skin and if
touched with fingers the product may transfer or become blotchy and
uneven. Perspiration or sebum will break through the film and cause
running or smearing. If skin comes into contact with clothing, the
clothing may become soiled.
[0005] The object of this invention is to formulate a cosmetic with
long lasting adherence to skin.
[0006] Another object of the invention is to formulate a cosmetic
which yields a film which is not disturbed when blotted to remove
sebum or perspiration.
[0007] Another object of the invention is to formulate a cosmetic
which yields a film which does not readily transfer to clothing or
utensils.
[0008] Another object of the invention is to formulate a cosmetic
which yields a film which exhibits reduced permeability to oil and
water.
SUMMARY OF THE INVENTION
[0009] The invention is directed to a cosmetic composition having
improved transfer resistance comprising:
[0010] a) from about 0.1-60% by weight of trimethylated silica,
[0011] b) from about 0.1-60% by weight of a volatile solvent having
a viscosity of 0.5 to 100 centipoise at 25.degree. C., and
[0012] c) 0.1-60% of a nonvolatile oil having a viscosity of 200 to
1,000,000 centipoise at 25.degree. C.
[0013] d) 0.1-80% of a cosmetically acceptable carrier.
