Title:
HYDROGEL INCLUDING MODIFIED CYCLODEXTRIN CROSSLINKED WITH POLYURETHANE PREPOLYMER
Document Type and Number:
WIPO Patent Application WO2007030661
Kind Code:
B1
Abstract:
A hydrogel composition comprising a modified cyclodextrin crosslinked with a polyurethane prepolymer. In one embodiment, the hydrogel includes a ratio of the modified cyclodextrin to the polyurethane prepolymer selected to result in formation of the hydrogel. The hydrogel composition may be used in a personal care product. A process for preparing a hydrogel, including providing a modified cyclodextrin; providing a polyurethane prepolymer; combining the modified cyclodextrin with the polyurethane prepolymer; and allowing the polyurethane prepolymer to react with and crosslink the cyclodextrin to form the hydrogel.
