Publication number: 20110263722Abstract: The present invention relates to the preparation and use of well defined star macromolecules wherein the composition of the arms are selected to induce self assembly when the multi-arm segmented star macromolecules are dispersed in a liquid. The self assembled star macromolecules modify the rheology of the dispersing media. When targeting use in aqueous based systems the inner shell of the star macromolecules comprise non-ionizable monomer units. Compositions comprising the self assemblable star macromolecules are suitable for use as rheology modifiers in a number of applications including cosmetic and personal care compositions.Type: ApplicationFiled: April 23, 2010Publication date: October 27, 2011Inventors: Wojciech Jakubowski, Patrick McCarthy, Nicolay Tsarevsky, James Spanswick
