  • Patent number: 8865144
    Abstract: Personal care compositions comprising responsive particles. In one aspect, the responsive particle comprises: (1) a particle core having an interfacial surface, (2) a first polymer having a first property, and (3) a second polymer having a contrasting property. The first polymer and the second polymer are attached at different locations to the interfacial surface of the particle core. In another aspect, the responsive particle comprises: (1) a particle core having an interfacial surface, (2) at least one block co-polymer comprising a first block and a second block, wherein said first block has a first property and said second block has a second property, and (3) optionally, at least one other polymer having a third property. The block co-polymer and the optional other polymer (if present) are attached to the interfacial surface of the particle core, and at least one of the properties contrasts. The personal care compositions also comprise a dermatologically acceptable carrier.

  • Patent number: 8349780
    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.

  • Publication number: 20100247800
    Abstract: 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.
