A polymer film suited to use as a face mask or transdermal patch includes at least 30 wt. % of a thermoplastic polyurethane polymer which is the reaction product of a first polyether polyol having a molecular weight of at least 3000 daltons, optionally, a second polyether polyol having a molecular weight of no more than 2500 daltons, at least one of a third polyol having a molecular weight of up to 800 daltons, and a chain extender, a diisocyanate, optionally, a catalyst. The film includes up to 5 wt. % water.

Thermoplastic polyurethane film for delivery of active agents to skin surfaces

A hydrogel composition from a cross-linked polymer derived from one or more olefinically unsaturated polymerizable carboxylic monomers and a thermoplastic polyurethane composition is disclosed. The hydrogel exhibits high yield stress at low shear. The hydrogel composition provides useful materials for personal care, health care, medical and pharmaceutical applications, among others.
