Abstract
Hair fixative preparations suitable for application to hair without subsequent rinsing are disclosed. The preparations are clear, aqueous mixtures of polydiorganosiloxane and a cationic, organic polymer. The preparations are used for setting hair and may be formulated into lotion and gel type products with superior aesthetics because of the clarity of the mixtures. The preparations are effective in providing flexible, long-lasting hold for hair styles.
Claims20
A clear, hair fixative composition suitable for application to hair without subsequent rinsing which composition consists essentially of
- (A) an aqueous microemulsion of a polydiorganosiloxane which conforms generally to the formula
- QMe.sub.2 SiO(MeRSiO).sub.y SiMe.sub.2 Q
- wherein Me denotes a methyl radical;
- R independently denotes methyl, ethyl, vinyl, or phenyl radicals with the proviso that at least 90 percent of R radicals are methyl, and Q denotes hydroxy, methyl, ethyl, vinyl, or phenyl;
- and y has an average value from 20 to 2000, wherein the polydiorganosiloxane droplet size of said microemulsion is less than 100 nm in diameter, and
- (B) a water-soluble, cationic, organic polymer containing amine or ammonium groups in the polymer chain or joined to the polymer chain,
- in a suitable aqueous carrier, wherein the weight ratio of polydiorganosiloxane to organic polymer in the composition is within the range of 1:20 to 2:1.
A method of setting hair comprising the steps of:
- moistening the hair with water, applying to the hair an effective amount of a composition consisting essentially of
- (A) an aqueous microemulsion of a polydiorganosiloxane which conforms generally to the formula
- QMe.sub.2 SiO(MeRSiO).sub.y SiMe.sub.2 Q
- wherein Me denotes a methyl radical;
- R independently denotes methyl, ethyl, vinyl, or phenyl radicals with the proviso that at least 90 percent of R radicals are methyl, and Q denotes hydroxy, methyl, ethyl, vinyl, or phenyl;
- and y has an average value from 20 to 2000, wherein the polydiorganosiloxane droplet size of said microemulsion is less than 100 nm in diameter, and
- (B) a water-soluble, cationic, organic polymer containing amine or ammonium groups in the polymer chain or joined to the polymer chain,
- in a suitable aqueous carrier, wherein the weight ratio of polydiorganosiloxane to organic polymer in the composition is within the range of 1:20 to 2:1, rolling the hair around a shaping device, and drying the hair while the hair is rolled.
