COMPOSITIONS AND METHODS INCORPORATING PHOTOCATALYSTS
摘要
<p>A personal care composition including an active material having functional 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. A method for treating hair is also disclosed. 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.</p>
