Abstract
Hydrolyzed jojoba protein is provided which can be used in a variety of cosmetic formulations to enhance the desirable properties thereof. The preferred hydrolyzed jojoba is in the form of an aqueous dispersion containing a mixture of amino acids, peptides and/or protein fractions derived from the hydrolysis of naturally occurring jojoba protein. Cosmetic formulations such as shampoos, shampoo conditioners, hair styling gels, hair conditioners, hair reparatives, bath and shower gels, skin lotions and creams, shaving creams, and sunscreens can be improved by incorporation of hydrolyzed jojoba protein therein. Defatted jojoba meal in a dispersion is hydrolyzed with a protease, acid is added. The protease is deactivated, and the resultant dispersion may be subjected to filtration to obtain permeate and retentate fractions. Sodium metabisulfite may be added after the acid.
