Personal care formulations containing keratin
A range of personal care products that include a keratin protein fraction. The fraction may be intact or hydrolysed. It is preferably S-sulfonated. The content of the fraction may range from 0.001% to 50%. In most formulations its content will be less than 1% although in certain products such as nail care products the content will be higher. A wide range of personal care products are described including shampoos, body gels and lotions, conditioners, creams and cosmetics generally.
