Topical composition, topical composition precursor, and methods for manufacturing and using |
摘要 |
A tropical composition is provided. The topical composition can be prepared by diluting a topical composition precursor with water and adding additional components, if desired. The topical composition precursor can be prepared by melt processing a hydrophobic polymer composition that includes repeating pyrrolidone/alkylene groups wherein the alkylene groups contain at least 10 carbon atoms, and a hydrophilic polymer composition including repeating carboxylic groups and/or repeating hydroxyl groups. A topical composition precursor and methods for manufacturing and using a topical composition are provided by the invention.
