Abstract
The present invention is directed to low VOC, non-aerosol hair cosmetic compositions, which contain nonionically modified starches. The starch may be additionally hydrolyzed, particularly enzymatically hydrolyzed. Further, the starch may be modified using ionic substituents. Use of such starches is novel and advantageous in that they provide a clear solution with a low viscosity, and good pump spray characteristics. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.
