(57) [Summary] (Modified)nSOLUTION: Oil-in-water emulsion for cosmetic or pharmaceutical use To prepare a polymer represented by the following general formula (I): The use of polyester modified polysiloxane and Providing an oil-in-water emulsion containing siloxane Offer. R (CH 3 ) 2 SiO-[(CH 3 ) 2 Si O] n -Si (CH 3 ) 2 R (I)n[Wherein n = 50-250, R =-(CH 2 ) m -O- (C 2 H 4 O) x − (C 3 H 6 O) y R 1 , M = 2 4, x = 3-100, y = 0-50, R 1 = H, C H 3 Or CH 2 CH 3 , Polye to total molecular mass The weight ratio of the ter group R is calculated according to a predetermined formula. If not more than 45% by weight. ]n[Effect] To obtain a homogeneous and stable oil-in-water emulsion And the feel is smooth after application Touch lasts. |
