COSMETIC PREPARATION HAVING BIPOLAR SENSORY PROPERTIES

摘要

Disclosed is a cosmetic W/O emulsion containing a) cetyl PEG/PPG-10/1 dimethicone and b) I) siloxane elastomer of the following structure: (I), where R1= C1 to C30 alkyl radical, R2= hydrogen, R3= a cross-link -E-Y-E- in which the other end of the cross-link is linked to a second silicone elastomer chain, each E represents a divalent group selected from among the groups -CH2-CH2- or -CH=CH-, and Y represents a divalent hydrocarbon group, a siloxane, or a combination of both, a = 265-2000, b= 0-249, C= 1-250, with the provision that b+c <= 250, said siloxane elastomer being swollen in a solvent, or II) a siloxane elastomer produced by reacting (A) a =Si-H-containing polysiloxane of formula R3SiO(R'2SiO)a(R"HSiO)bSiR3 and, optionally, a =Si-H-containing polysiloxane of formula HR2SiO(R'2SiO)cSiR2H or of formula HR2SiO(R'2SiO)a(R"HSiO)bSiR2H, where R, R' und R" = alkyl groups with 1 to 6 C atoms, a=0-250, b=1-250, und c=0-250, with (B) an alpha,omega-diene of formula CH2=CH(CH2)xCH=CH2 where x=1-20, the reaction being carried out in the presence of a palladium catalyst, and (C) a solvent selected from among the group consisting of (i) organic components, (ii) components containing a silicone atom and any mixtures thereof, the reaction being carried out until a gel is obtained using cross-linking by adding =Si-H to the double bonds of the alpha,omega-diene.
