Abstract
The present invention relates to a composition including 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. The active is a silicone polymer and/or a silicone oligomer, having a molecular weight higher than 1,000 grams/mole, and at least one organic functional group. The compositions may also include surfactants, emulsifiers, oxidants, and other components. A method for treating a substrate is also disclosed. The compositions and methods described herein are useful in personal care product and consumer care product applications.
