Title:
NOVEL USE OF SILICONE ELASTOMERS IN COSMETIC PREPARATIONS
Document Type and Number:
WIPO Patent Application WO/2013/000743
Kind Code:
A3
Abstract:
The invention relates to the use of a siloxane elastomer, which is swollen in a solvent, in cosmetic preparations in order to increase the water-resistance of said preparations. Said gel: I) is produced by reacting (A) an ≡Si-H-containing polysiloxane of formula R3SiO(R'2SiO)a(R''HSiO)bSiR3 and optionally an ≡Si-H-containing polysiloxane of formula HR2SiO(R'2SiO)cSiR2H or formula HR2SiO(R'2SiO)a(R''HSiO)bSiR2H, where R, R' and R'' = alkyl groups comprising 1 to 6 C atoms, a = 0-250, b = 1-250, and c = 0-250, (B) with an alpha, omega diene of formula CH2=CH(CH2)xCH=CH2, where x = 1-20, said reaction being carried out in the presence of a platinum catalyst and (C) a solvent selected from the group consisting of (i) organic components, (ii) components containing a silicone atom and any mixtures thereof and being carried out until a gel is achieved by cross-linking by the addition of ≡Si-H to the double bonds of the alpha, omega diene, or; II) has the following structure (AA) where R1 = a C1 to C30 alkyl group, R2 = hydrogen, R3 = a cross-link -E-Y-E-, in which the other end of the cross-link is connected to a second silicone elastomer chain, each E represents a divalent group selected from the groups -CH2-CH2- or -CH=CH- and Y represents a divalent hydrocarbon group, a siloxane or a combination of the two, a = 265-2,000, b = 0-249 and C = 1-250, with the proviso that b+c ≤ 250.
