摘要:
A film-forming composition in a solution form, comprising(A) a Silicone resin comprising SiO2 units and R3SiO1/2 units, wherein R is a C1-6 monovalent hydrocarbon group, with a molar ratio of the R3SiO1/2 units to the SiO2 units ranging from 0.5 to 1.5, said silicone resin may comprise R2SiO and RSiO3/2 units,provided that a total content of the R3SiO1/2 units and the SiO2 units is at least 80 mole % of all of the units,(B) an organopolysiloxane represented by the following formula (I),wherein R is a C1-6 monovalent hydrocarbon group, R1 is a monovalent group selected from the group consisting of C1-6 monovalent hydrocarbon groups, a hydroxyl group, C7-30 monovalent aliphatic hydrocarbon groups, -C3 H6NH2 and -C3H6 NHC2 H4NH2, R2 is a C7-30 monovalent aliphatic hydrocarbon group, R3 is -C3H6 NH2 or -C3H6NHC2H4NH2, a is an averaged number ranging from 450 to 2950, b is an averaged number ranging from 50 to 1500, c is an averaged number ranging from 0 to 50, provided that a+b+c ranges from 500 to 3,000, and(C) an organic solvent.The composition forms a non-sticky and abrasion resistant film and is useful for cosmetics or drugs to protect the skin or hair.
