Abstract: The present invention relates to a composition, preferably for use in a therapeutic method for improving or preventing one or more undesired skin conditions. Furthermore, the present invention relates to a cosmetic and/or dermatological preparation comprising such a composition.

Abstract: Novel compositions comprising anionic-cationic complexes as conditioning agents for use in products that improve the appearance and feel of skin and hair are well known. This invention describes the use of additional cationic surfactant in combination with an anionic-cationic complex made from a fatty alkyl dialkylamine and a “dicarboxylic acid”, preferably a dimer acid. This combination provides exceptional conditioning for hair, improving both wet and dry combing. It also makes very stable oil-in-water emulsions, and adds a slippery feel and lubricity to shaving and skin cleaning products.

Abstract: The present invention relates to the use of cross-linked silicone gel, in particular, a polymerization product of a polyorganohydrosiloxane, with the proposed INCI name (Dimethicone/polymethylalkyl siloxane copolymer), in cosmetic applications to provide unexpected characteristics related to formulations incorporating these silicone gels.

Abstract: The use of novel nonionic polymeric thickeners that produce cosmetically useful emulsions of an oil phase and a water phase is described. The thickeners of choice are the urethane dimers of ethoxylated fatty alcohols. These materials were not anticipated to have emulsifying properties. Also, it has been found that the esters of ethoxylated polyols show similar emulsifying behavior, although their uses are limited by their inherent susceptibility towards hydrolysis. Further, many of the emulsions produced with these emulsifiers have a dilatant or shear thickening rheology that is unusual and has unique cosmetic applications. In addition, it is possible to produce high internal phase oil-in-water emulsions, with oil phase concentrations greater than 70%, using these emulsifiers. Finally, many of the emulsions, especially the high internal phase ones, have a characteristic “ring” or vibration that is apparent when their container is tapped.
