The present invention includes compositions comprising an active material having groups capable of covalent attachment to a substrate in the presence of an acid or a base, a photocatalyst capable of generating an acid or a base upon exposure to light, and a vehicle. Also included herein is a method for treating a substrate with these compositions. The method includes the steps of applying at least one active material having functional groups to the substrate, applying a photocatalyst to the substrate, and exposing the photocatalyst and the at least one active material to light for forming covalent attachments between the functional groups and constituent groups on the substrate. The compositions and methods described herein are useful in consumer care and personal care product applications.
