Abstract
Hair care compositions contain from 0.1 to 12 weight percent of a silicone copolymer or saponification product thereof, prepared from silicones, at least 10% of which contain polymerizable groups, 0.5-14% of hydrophilic comonomers, and 30-99.9% of hydrophobic comonomers. The compositions exhibit good hair care properties.
Claims8
A hair care composition comprising 0.1-12% by weight based on the weight of the hair care composition of at least one silicone copolymer and/or saponification product thereof, the silicone copolymer prepared by copolymerizing monomers comprising
- A) 0.1-50% based on the weight of the silicone copolymer, of one or more polymerizable silicones of the formula
- R1R2SiO(SiR2O)nSiR2R1 (1)
- where
- R is methyl,
- R1 is vinyl, and
- n is 10 to 1000
- B) 0.5-14% of one or more copolymerizable unsaturated hydrophilic monomers based on the weight of the silicone copolymer, and
- C) 30-99.4% of one or more copolymerizable unsaturated hydrophobic monomers based on the weight of the silicone copolymer, the polymerization taking place in the presence of a free radical initiator compound,
- with the proviso that the molecular weight MW of the silicone copolymer is 30,000 to 90,000 g/mol and organic polymer chains are covalently bridged by silicone chains derived from said polymerizable silicones A), the hair care composition further comprising 99.9 to 88% by weight of hair care composition components other than the silicone copolymer.
