In an embodiment, the present invention relates to compositions, and methods for using compositions, comprising at least one silicone, at least one compound comprising at least one ester group, and at least one copolymer comprising at least one backbone and at least one chain, wherein at least one of the at least one backbone and at least one chain is chosen from silicones. In an embodiment, the inventive compositions do not comprise any volatile solvents.
Cosmetic and/or dermatological products may comprise a structured, i.e., gelled and/or rigidified, liquid fatty phase, such as in solid compositions, for example, deodorants, lip balms, lipsticks, concealer products, eyeshadows, and cast foundations. This structuring may be obtained with the aid of waxes and/or fillers. Unfortunately, these waxes and fillers may have a tendency to make the composition matte, which may not always be desirable, in particular for a lipstick or an eyeshadow. Specifically, consumers may be interested in a lipstick in stick form which has at least one of the following properties: depositing a film with good staying power and/or long wearing properties, glossiness, and wear comfort.
Gloss of a lipstick or other cosmetic is generally associated with the nature of the liquid fatty phase. Thus, it may be possible to reduce the amount of waxes and/or fillers in the composition to increase the gloss of a lipstick, often, however, that leads to an increase in the migration of the liquid fatty phase. In other words, the amounts of waxes and of fillers required to prepare a stick of suitable hardness which does not exude at room temperature are usually a restricting factor on the gloss of the deposit.

Preparation
Hydrogenated polyisobutene, isononyl isononanoate, phenyltrimethicone, and the excess over 15% of diisostearyl malate were added to a mixing kettle and the mixture was heated to 90° C. to 95° C. under medium agitation. Stearyl heptanoate was then added to the mixing kettle, and the resulting mixture was mixed until homogeneous at 90° C. to 95° C. One by one dipentaerythrityl tetrahydroxy stearate/isostearate, acrylates/stearyl acrylated/dimethicone acrylated copolymer and trimethylsiloxysilicate (SR1000) were added to the mixture, ensuring that each individual component was melted and homogeneous. The resulting mixture was mixed for another 20 minutes at 90° C. to 95° C. Finally, BHT was added, and the resulting mixture was mixed for 20 minutes at 90° C. to 95° C.
