The present invention is directed to a low VOC, non-aerosol, polyacrylic acid containing hair cosmetic compositions which contain stabilized starches, particularly those derivatized by alkylene oxides, about 01.-0.0% polyacrylic acid, up to about 15% solvent, and water. The derivatized starch may be hydrolyzed, particularly enzymatically hydrolyzed by at least one endo-enzyme. In addition, the starch may be cationically modified with a low degree of substitution. Use of such starches is novel an...
