The various embodiments provide a 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. The compositions may also include surfactants, emulsifiers, oxidants, and other components. A method for treating a substrate 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. The compositions and methods described herein are useful in personal care product and consumer care product applications, for example.
各种实施例提供了一种组合物,包括具有在酸或碱存在下能够与基底共价结合的功能基团的活性材料,能够在光照下生成酸或碱的光催化剂,以及载体。该组合物还可以包括表面活性剂、乳化剂、氧化剂和其他组分。还公开了一种处理基底的方法。该方法包括将至少一种具有功能基团的活性材料应用于基底,将光催化剂应用于基底,并将光照射到光催化剂和至少一种活性材料,以形成功能基团与基底上的成分基团之间的共价结合。这里描述的组合物和方法在个人护理产品和消费者护理产品应用中是有用的。
