Embodiment 1
[0464] Embodiment 1 (comparison)
[0465] In this example, which does not follow the invention, cosmetic formulations for the lips and face are prepared from silicone only with silicone polyamide as structuring agent and phenylated silicone as oil.
[0466] The formulation is then colored and cast in cans.
[0467] The composition of the prepared formulation is given below:
[0468]
[0469] *DP: degree of polymerization
[0470] The silicone polymer, melted at 110° C., is mixed with a portion of the oil in order to obtain a liquid mixture. Meanwhile, the pigments are ground in the remaining portion of the oil. Finally, the pigmented ground product was mixed with the oil+gelling agent mixture at 110°C.
[0471] The deposits obtained from the strip on the hands are fine and uneven.
[0472]In conclusion, it appears that the formulation prepared in this comparative example was hard, depositing only minimal color during application (very difficult).
Embodiment 2
[0474] In this example according to the invention, a cosmetic preparation with a composition similar to claim 1 was prepared, except that 20% by mass of the compound according to the invention, which lowers the melting temperature of the polymer, octyldodecanol, was added to the preparation middle.
[0475] The composition of the prepared formulation is given below:
[0476]
[0477] *DP: degree of polymerization
[0478] The silicone polymer, melted at 110° C., is mixed with a portion of silicone oil and octyldodecanol in order to obtain a liquid mixture. Meanwhile, the pigments are ground in the remaining portion of the oil. Finally, the pigmented ground product was mixed with the oil+gelling agent mixture at 110°C.

Abstract
The invention refers to a nursing and / or make-up cosmetic composition structured with a silicone polymer, comprising a liquid continuous fatty phase structured with at least one structuring polymer having a weight average molecular weight of 500-500000 containing at least one moiety comprising at least one polyorganosiloxane group consisting of 1-1000 organosiloxane units in the chain of the moiety or in the form of a graft, and at least two groups capable of establishing hydrogen interactions consisting of ester, amide, sulfonamide, carbamate, thiocarbamate, urea, urethane, thiourea, oxamido, guanidino and/or biguanidino groups. The polymer is solid at room temperature and soluble in the liquid fatty phase at 25-250 degrees C. The liquid fatty phase comprises at least one compound capable of reducing the enthalpy of fusion of the structuring polymer. The composition contains at least one pigment. The liquid fatty phase, the structuring polymer and the compound capable of reducing the enthalpy of fusion of the structuring polymer form a medium.
Description
[0001] This application is a PCT international filing date of December 8, 2003, entering the Chinese national phase on August 17, 2005, entitled "Care and / or beauty cosmetic composition structured with a silicone polymer", China The divisional application of the patent application whose application number is 200380109797.9. technical field [0002] The present invention relates to a care and / or cosmetic composition for human skin, including hair, and / or lips, comprising a liquid fatty phase comprising at least one oil, structured with specific polymers, especially in the form of cast cosmetics Provided in a form, especially as a stick or dome cosmetic product, such as a lipstick, its application is easy, yielding a high volume, especially pigmented, glossy and non-migrating deposit. [0003] Cosmetic compositions for care include, for example, for the treatment of wrinkles, for moisturizing the skin and lips, for protecting the skin, lipstick and growths from UV rays, for trea...
