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. A process for preparing a hydrogel-containing article such as a personal care product, including preparing the hydrogel and applying it or the components thereof to a suitable substrate.
