ABSTRACT:
Novel skin care, hair care, nail care, lip care and related external formulations based on partial and complete choline salts of mono, di, tri and polyvalent carboxylic acids of food, cosmetic and pharmaceutical acids are described. These salts have better moisturizing and treating properties compared to the original acids. They tend to form highly elegant cosmetic treatment products when incorporated into lotions, creams, gels, liquids, bars, sticks, sprays and foam products. The mono choline salts of di and polyvalent carboxylic acids are also described in the invention. These mono choline salts tend to retain or enhance the biological properties of the parent molecule with enhanced solubility and bio-availability. These mono choline salts can be formulated as simple solutions and lotions eliminating need of complicated solubilizing systems. The partial and mono choline salts tend to reduce irritation, burning and stinging sensation common to these carboxylic acids.
