Abstract
Organopolysiloxane gel compositions containing an organopolysiloxane gel produced by hydrosilylation of an unsaturated silicone resin and a compound containing glycoside residues and a hydrosilylatable group with at least one Si—H-functional organopolysiloxane can form creamy, storage-stable gels which are capable of containing large amounts of polar or hydrophilic substances such as water and glycerol while remaining monophasic. The compositions are especially useful in providing cosmetic compositions with a silky skinfeel.

16. A composition comprising at least one organopolysiloxane gel having glycoside residues prepared by reacting:
-
(1a) unsaturated organopolysiloxane resin(s) and (1b) compound(s) having a glycoside residue and a hydrosilylatable group, with the proviso that the proportion by weight of the compound (1b), based on the total weight of the organopolysiloxane gel, is 0.1% to 10% by weight, with (2) Si—
H-functional organopolysiloxane(s) of the formula
HcR3-cSiO(R2SiO)a(RHSiO)bSiR3-cHc
(I)where c is 0 or 1, R are the same or different and are monovalent, optionally substituted hydrocarbyl radicals having 1 to 18 carbon atoms per radical, a and b are integers, with the proviso that the sum of a+b is 66 to 248, wherein the organopolysiloxanes (2) contain Si-bonded hydrogen in amounts of 0.011% to 0.044% by weight, and the average number of Si—
H groups per molecule is greater than 2 and less than 5, or mixtures of Si—
H-functional organopolysiloxanes (2) with(2′
) Si—
H-functional organopolysiloxanes of the formula
HcR3-cSiO(R2SiO)a(RHSiO)bSiR3-cHc
(I′
)where c is 0 or 1, R is as defined above, a and b are integers, with the proviso that the sum of a+b is 8 to 248, and the organopolysiloxanes (2′
) contain Si-bonded hydrogen in amounts of 0.045% to 0.35% by weight,in the presence of (3) catalysts that promote the addition of Si-bonded hydrogen onto aliphatic multiple bonds, where (1a) and (1b), and (2) or mixtures of (2) and (2′
) are dispersed in (4) diluent(s). - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
