    Abstract: An object is to provide a crosslinked organosilicone resin which has a crosslinked structure formed by reacting a silicone or hydrocarbon having an alkenyl group at both ends thereof with a hydrosilyl group-containing organosilicone resin, is soluble with a liquid oil at room temperature, and forms a film by volatilization of the oil, and to provide a method for preparing the same and cosmetics containing the crosslinked organosilicone resin. The present invention provides a crosslinked organosilicone resin represented by the following average composition formula (1): (R13SiO1/2)a1(R23SiO1/2)n2(R33SiO1/2)n3(R13-p(X1/2)pSiO1/2)a4(R12SiO2/2)b(R1SiO3/2)c(SiO4/2)d   (1) wherein R1 is, independently of each other, a substituted or unsubstituted, monovalent hydrocarbon group having 1 to 30 carbon atoms and having no aliphatic unsaturated bond, R2 is, independently of each other, a polyoxyalkylene-containing group, a polyglycerin-containing group, or a group selected from the groups defined for R1 and at least one of R2 in each of the R23SiO1/2 units is a polyoxyalkylene-containing group or a polyglycerin-containing group, R3 is, independently of each other, an organopolysiloxane-containing group or a group selected from the groups defined for R1 and at least one of R3 in each of the R33SiO1/2 units is an organopolysiloxane-containing s group, X is a divalent group represented by the following formula (2) or (3): wherein R4 is, independently of each other, a substituted or unsubstituted, monovalent hydrocarbon group having 1 to 30 carbon atoms and having no aliphatic unsaturated bond, e is an integer of 0≤e≤500 and k is an integer of 0≤k≤5; —(CH2)2—CfH2f—(CH2)2—  (3) wherein f is an integer of 0≤f≤20; optionally, a part of R2, R3 and X may be a hydroxyl group, a1, a2, a3, a4, b, c, and d satisfy the equations, 0

    Abstract: A gel paste composition including (A) a crosslinking organopolysiloxane and (B) a liquid oil, the crosslinking organopolysiloxane (A) being obtained by reacting an organohydrogenpolysiloxane shown by the following general formula (I) with a polyoxyalkylene compound shown by the following general formula (II) in the presence of a catalyst for hydrosilylation reaction, the component (A) containing polyoxyethylene units in an amount of 20 wt % or more. As a result, the gel paste composition that contains a crosslinking organopolysiloxane having improved compatibility with ethylhexyl methoxycinnamate and water, and thus exhibits excellent dispersibility when blended to a cosmetic thereby providing good feeling and cosmetic sustainability.
