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.

Hydrogel compositions

The present invention relates to esterified glycerylated alkyl glycoside and to a process for making same. The esterified glycerylated alkyl glycoside have one or more polyglyceryl moieties and one or more acyl moieties, wherein all of the one or more acyl moieties are situated on the one or more polyglyceryl moieties via an ester linkage. These compounds have been found to be useful as emulsifiers and coemulsifiers in the formulation of a phase stable emulsions suitable for use in personal care, home care, industrial and institutional, and health care applications.

Branched polymeric emulsifiers

This invention relates to cationically derivatized polycalactomannans obtained fromandand to their use in personal care, household care, and institutional care compositions.

Cationic cassia derivatives and applications therefor

This invention relates to A bioadhesive composition comprising two or more essentially excretable, essentially non-degradable polymer backbones, wherein the polymer backbones are crosslinked, said crosslink being degradable in a mammal, said cross-linked bioadhesive composition having an average bioadhesion factor showing bioadhesion equivalent to at least about 100 g s. The concept is to build a hydrogel that demonstrates bioadhesion to a mucosal surface that is crosslinked by a degradable linkage such as disulfide for use inside the body.

Bioadhesive hydrogels with functionalized degradable crosslinks

A rheology modifying copolymer composition containing a cross-linked copolymer of unsaturated carboxylic acid, a hydrophobic monomer, a hydrophobic chain transfer agent, a cross linking agent, and, optionally, a steric stabilizer, provides increased viscosity in aqueous electrolyte-containing environments.

Rheology modifying copolymer composition

Improved crosslinked ionic polymers or salts thereof having a soluble polymer fraction of less than about 15 wt %, and methods for making the same. The polymers are useful as bioadhesives, thickeners, emulsifiers, suspending aids, and pharmaceutical controlled release excipients.
