The present invention is directed to a low VOC, non-aerosol, polyacrylic acid containing hair cosmetic compositions which contain nonionically derivatized starches, particularly those derivatized by alkylene oxides. 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 and advantageous in that they are compatible with polyacrylic acid, providing a clear, solution with a stable viscosity. Further, the resultant composition provides a clear film which is not tacky, good stiffness, and improved humidity resistance.
本发明涉及一种低挥发性有机化合物(VOC)、无气溶胶、含聚丙烯酸的护发化妆品组合物,该组合物含有非离子衍生化淀粉,特别是那些由亚烷基氧化物衍生化的淀粉。衍生化淀粉可以水解,特别是通过至少一种内切酶进行酶水解。此外,淀粉还可以进行低取代度的阳离子改性。使用这种淀粉的新颖性和优点在于它们与聚丙烯酸相容,可提供粘度稳定的透明溶液。此外,由此产生的组合物还能提供不粘手的透明薄膜、良好的挺度和更好的防潮性能。
