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. R1aHbSiO(4-a-b)/2 (I)CcH2c-1O(C2H4O)d(C3H6O)eCcH2c-1 (II).
