Claims20
A cosmetic composition comprising:
- an aminoalcohol-modified organopolysiloxane as a surfactant, said aminoalcohol-modified organopolysiloxane having a backbone composed of organopolysiloxane segments, at least one silicon atom in the organopolysiloxane segment having bonded thereto a substituent group of the general formula (1):
- wherein X and Y are each independently a divalent hydrocarbon group of 1 to 10 carbon atoms, m is an integer of 0 to 4, and Z is independently a group selected from hydrogen, alkyl of 1 to 16 carbon atoms, and phenyl, or a group selected from —CH2—CH2—OH, —CH2—CH(OH)—CH3, and —CH2—CH(OH)—CH2—OH, at least 10 mol % of the entire substituent groups represented by Z being the group selected from —CH2—CH2—OH, —CH2—CH(OH)—CH3, and —CH2—CH(OH)—CH2—OH, and Z comprises only one group selected from —CH2—CH2—OH, —CH2—CH(OH)—CH3, and —CH2—CH(OH)—CH2—OH,
- wherein said aminoalcohol-modified organopolysiloxane has the general formula (2):
- wherein R1 is each independently a group selected from hydrogen, hydroxyl, alkoxy of 1 to 3 carbon atoms, alkyl of 1 to 16 carbon atoms, and phenyl, R2 is the group of formula (1), R3 is a group selected from hydrogen, hydroxyl, alkoxy of 1 to 3 carbon atoms, alkyl of 1 to 16 carbon atoms, and phenyl, n is an integer of 0 to 10,000, and t is an integer of 1 to 100;
- wherein if Z comprises —CH2—CH2—OH, m=0,
- if Z comprises —CH2—CH(OH)—CH2—OH, m=0,
- if Z comprises —CH2—CH(OH)—CH3,
- (i) R3 is alkoxy group of 1 to 3 carbon atoms,
- (ii) at least one of R1 if phenyl group, or
- (iii) n is an integer of 3,000 to 10,000;
- and
- a cosmetically acceptable ingredient.
