The use of novel nonionic polymeric thickeners that produce cosmetically useful emulsions is described. The thickeners of choice are the urethane dimers of ethoxylated fatty alcohols and esters of ethoxylated polyols. 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%.
