Abstract: The instant disclosure relates to masks, methods for making masks, methods for improving film elasticity of masks, and to methods of treating skin with masks. The masks are formed by applying a mask base composition onto a surface, the mask base composition comprising: (i) alginic acid and/or a salt thereof; (ii) hectorite (lithium magnesium sodium silicate); (iii) one or more water-soluble solvents; and (iv) water; and exposing the mask base composition to a crosslinking composition for a time sufficient to crosslink the alginic acid and/or a salt thereof and form a final mask, the crosslinking composition being an aqueous liquid comprising (i) one or more polyvalent cations of one or more metals; and (ii) water. The instant disclosure further relates to masks formed by the disclosed methods and to kits comprising the compositions for making and/or using the masks.

Abstract: Certain embodiments of the invention provide a lubricating oil composition comprising a lubricating oil base stock and a compound of formula (I): or a salt thereof, wherein R1, R2, R3 and R4 have any of the values defined in the specification, as well as methods of use thereof.

Abstract: A controlled release system for kojic acid having improved stability has been identified. To minimize degradation, kojic acid was incorporated into a hydrolytically degradable polymer (e.g., a polycarbonate-ester)). By synthesizing polymer precursors containing kojic acid-linker-kojic acid chemical structures, versatile monomers were developed that can be used to modulate polymer properties. Additionally the synthetic method lends itself to the development of other polymer systems. Polymers having one or more groups that will yield kojic acid upon degradation of the polymer backbone, as well as methods of use thereof are described.
