  • Patent number: 7964179
    Abstract: The invention provides hair cosmetics which can suppress a frictional feeling of hair in running water during rinsing to improve softness and smoothness thereby preventing the hair from being damaged by twisting during rinsing, and comprises organopolysiloxane having an amino-modified organopolysiloxane chain and a polyoxyalkylene chain, and at least one cationic surfactant selected from compounds represented by formula (1) or (2): wherein at least one of R1, R2, R3 and R4 represents e.g. an alkyl group containing 8 to 35 carbon atoms in total, and the remainder represents a C1 to C5 alkyl group, hydroxyalkyl group etc., X? represents a halogen ion or an organic anion, R5 represents e.g. an alkyl group containing 8 to 35 carbon atoms in total, and R6 represents a C1 to C22 alkyl group etc.

  • Patent number: 5747016
    Abstract: An organopolysiloxane which generates intramolecular or intermolecular cross-linking based on dipole-dipole interaction, hydrogen bonding or ion bonding, and which is not ruptured or plastically deformed at an extension ratio no more than 15% at a temperature of 20.degree. C. under relative humidity of 65%; and a method of setting hair using the same. Hair which is set by the method retains the given shape over time, and the organoplysiloxane imparts a soft touch to the hair. In addition, the shape given by the setting treatment can be easily restored to the original shape by ordinary shampooing.
