Cosmetic composition comprising a volatile fatty phase

The invention relates to a composition comprising, in a physiologically acceptable medium, a volatile silicone fatty phase comprising at least one non-cyclic volatile silicone oil, wherein the volatile silicone fatty phase has an evaporation profile such that the mass of the at least one volatile silicone oil evaporated after 30 minutes is from 2 mg/cm2 to 9 mg/cm2. The invention also relates to making up and caring for human keratin materials using the inventive compositions.

Catalysis of hydrosilylation: Part XXXIV. High catalytic efficiency of the nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}]

The nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}] (1) appeared to be a very efficient catalyst for dehydrogenative coupling of vinyl derivatives (styrene, vinylsilanes, vinylsiloxanes) with trisubstituted silanes HSi(OEt)3, HSiMe2Ph. The reaction occurs via three pathways of dehydrogenative coupling, involving formation of an unsaturated compound as the main product as well as a hydrogenated olefin (DS-1) pathway, hydrogenated dimeric olefin (DS-2) and dihydrogen (DC), respectively. The reaction is accompanied by side hydrosilylation. Stoichiometric reactions of 1 with styrene and triethoxysilane, in particular synthesis of the bis(triethoxysilyl) (divinyltetramethyldisiloxane) nickel complex 3 and the first documented insertion of olefin (styrene) into Ni-Si bond of complex 3, as well as all catalytic data have allowed us to propose a scheme of catalysis of this complex reaction by 1.

Treatment of alkyltriethoxysilanes with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane

Methyltriethoxysilane and ethyltriethoxysilane were treated with Amberlyst 15 cation-exchange resin in the presence of hexamethyldisiloxane at 40 deg C.The reaction involves partial or full replacement of the ethoxyl group by trimethylsiloxyl to give RSi(OEt)n(OSiMe3)3-n (n=0, 1, 2).The degree of substitution depends mainly on the ratio in which hexamethyldisiloxane and alkyltriethoxysilane are mixed.The nature of alkyl group in an alkyltriethoxysilane had little effect on the degree of substitution at a given mixing ratio.
