ABSTRACT:
TECHNICAL FIELD
The invention is in the field of color cosmetic compositions for application to skin and lips.
BACKGROUND OF THE INVENTION
Recently transfer resistant cosmetic compositions have become very popular. Women of the nineties lead busy lives and are interested in color cosmetic products that are long lasting and comfortable to wear. While the current transfer resistant cosmetics stay on the skin very well, in some cases they tend to be drying and uncomfortable to wear. In addition, transfer resistant films also tend to have a matte texture, which some women do not find attractive. The ideal color cosmetic composition should be durable and long lasting, comfortable to wear, and provide a finish which is semi-matte or even shiny.
The object of the invention is to provide a color cosmetic composition that provides a long lasting durable finish on the skin and is comfortable to wear.
Another object of the invention is to provide a color cosmetic composition that is transfer resistant and provides a semi-matte or shiny finish.
Another object of the invention is to provide a transfer resistant lipstick composition that provides a semi-matte or shiny finish on the lips.

DETAILED DESCRIPTION
The color cosmetic composition of the invention may be a lipstick in the stick or liquid form, blush, eyeshadow, foundation, concealer, and the like, and may be in the anhydrous or emulsion form. The composition contains at least one silicone compatible organic oil and at least two silicones, preferably three, silicones selected from the group consisting of (A)-(D), above.
I. SILICONE COMPATIBLE ORGANIC OIL
The silicone compatible organic oil may be an ester, hydrocarbon oil, or an animal, vegetable, or mineral oil. The term “compatible” means that the organic oil is soluble or dispersible in the silicone mixture to form a stable solution or dispersion. The organic oil is a liquid at room temperature (25° C.) and preferably has a viscosity of about 10 to 600,000, preferably 20 to 500,000, more preferably 50 to 300,000 centipoise at 25° C. The composition comprises 0.1-80%, preferably 0.5-70%, more preferably 1-50% by weight of the total composition of the silicone compatible organic oil.
A. Esters
Suitable silicone compatible organic esters are mono-, di-, and triesters. The composition may comprise one or more esters selected from the group, or mixtures thereof. Preferably the composition contains a mixture of di- and triesters, and in a ratio of 0.1-10% diester and 0.1-15% triester, by weight of the total composition. Particularly preferred compositions comprise a mixture of mono-, di- and triesters in a ratio of 0.01-10% monoester, 0.1-10% diester, and 0.1-15% triester, all percentages being by weight of the total composition.
1. Monoesters
Monoesters are defined as esters formed by the reaction of a monocarboxylic acid having the formula R—COOH, wherein R is a straight or branched chain saturated or unsaturated alkyl having 2 to 30 carbon atoms, or phenyl; and an alcohol having the formula R—OH wherein R is a straight or branched chain saturated or unsaturated alkyl having 2-30 carbon atoms, or phenyl. Both the alcohol and the acid may be substitued with one or more hydroxyl groups, and in one preferred embodiment of the invention the acid is an alpha hydroxy acid. Either one or both of the acid or alcohol may be a “fatty” acid or alcohol, ie. may have from about 6 to 22 carbon atoms. Examples of monoester oils that may be used in the compositions of the invention include hexyldecyl benzoate, hexyl laurate, hexadecyl isostearate, hexydecyl laurate, hexyldecyl octanoate, hexyldecyl oleate, hexyldecyl palmitate, hexyldecyl stearate, hexyldodecyl salicylate, hexyl isostearate, butyl acetate, butyl isostearate, butyl oleate, butyl octyl oleate, cetyl palmritate, ceyl octanoate, cetyl laurate, cetyl lactate, cetyl isononanoate, cetyl stearate, stearyl lactate, stearyl octanoate, stearyl heptanoate, stearyl stearate, and so on. It is understood that in the above nomenclature, the first term indicates the alcohol and the second term indicates the acid in the reaction, i.e. stearyl octanoate is the reaction product of stearyl alcohol and octanoic acid. Preferred is monoester which is the reaction product of an aliphatic C
2-8
alcohol and a C
14-22
fatty acid, more particularly, the reaction product of a hexyl alcohol and lauric acid, also referred to as hexyl laurate.
2. Diesters
Suitable diesters that may be used in the compositions of the invention are the reaction product of a dicarboxylic acid and an aliphatic or aromatic alcohol. The dicarboxylic acid may contain from 2 to 30 carbon atoms, and may be in the straight or branched chain, saturated or unsaturated form. The dicarboxylic acid may be subsituted with one or more hydroxyl group. The aliphatic or aromatic alcohol may also contain 2 to 30 carbon atoms, and may be in the straight or branched chain, saturated, or unsaturated form. The aliphatic or aromatic alcohol may be substituted with one or more substitutents such as hydroxyl. Preferably, one or more of the acid or alcohol is a fatty acid or alcohol, i.e. contains 14-22 carbon atoms. The dicarboxylic acid may also be an alpha hydroxy acid. Examples of diester oils that may be used in the compositions of the invention include diisostearyl malate (the reaction product of isostearic alcohol and malic acid), neopentyl glycol dioctanoate (the reaction product of neopentyl glycol and 2-ethyl hexanoic acid), dibutyl sebacate (reaction product of butyl alcohol and sebacic acid), di-C
12-13
alkyl malate (reaction product of C12-13 alcohol and malic acid), dicetearyl dimer dilinoleate (reaction product of cetearyl alcohol and adipic acid), dicetyl adipate (reaction product of cetyl acohol and adipic acid), diisocetyl adipate (reaction product of hexadecyl alcohol and adipic acid), diisononyl adipate (reaction product of isononyl alcohol and adipic acid), diisostearyl dimer dilinoleate (reaction product of isostearyl alcohol and dilinoleic acid), disostearyl fumarate (reaction product of isostearyl alcohol and fumaric acid), and so on.
3. Triesters
Suitable triesters comprise the reaction product of a tricarboxylic acid and an aliphatic or aromatic alcohol. As with the mono- and diesters mentioned above, the acid and alcohol contain 2 to 30 carbon atoms, and may be saturated or unsatured, straight or branched chain, and may be substituted with one or more hydroxyl groups. Preferably, one or more of the acid or alcohol is a fatty acid or alcohol containing 14 to 22 carbon atoms. Examples of triesters include triarachidin (reaction product of glycerin and arachidic acid), tributyl citrate (reaction product of butyl alcohol and citric acid), tri C12-13 alkyl citrate (reaction product of C12-13 alcohol and citric acid), tricaprylin (reaction product of glycerin and caprylic acid), tricaprylyl citrate (reaction product of capryl alcohol and citric acid), tridecyl behenate (reaction product of tridecyl alcohol and behenic acid), trioctyldodecyl citrate (reaction product of octyldodecyl alcohol and citric acid), tridecyl behenate (reaction product of tridecyl alcohol and behenic acid), tridecyl cocoate (reaction product of tridecyl alcohol and coconut acid), tridecyl isononanoate (reaction product of tridecyl alcohol and isononanoate), and so on. Preferred is a triester which is the reaction product of an alpha hydroxy acid and a guerbet alcohol having 6 to 30 carbon atoms, in particular the reaction product of citric acid and octyldodecyl alcohol, referred to as trio
