  • Compositions and methods for treating hair using a mixture of polysiloxanes
    Patent number: 5585094
    Abstract: Methods and compositions for semi-permanently conditioning hair by treating the hair, preferably following shampooing, with a composition including a low viscosity oil-in-water emulsion of a mixture of two polysiloxane polymers, that is, a hydroxy terminated dimethyl polysiloxane and a methyl hydrogen polysiloxane, the composition being at an acid pH. It is a feature of this invention that the polysiloxane polymers in the hair-treating composition are in an unreacted or non-crosslinked state. After the composition is applied to the hair, the crosslinking of the two polysiloxane polymers takes place on the hair resulting in a semi-permanent conditioning effect. Although some crosslinking of the polymers will occur while drying the treated hair at room temperatures, increased crosslinking occurs when the hair is blow dried using heated air.
