Balancing Texture with Electrolyte Resistance for Improved Thickening

Mar 1, 2015Ryosuke Murakami, Yusuke Nishikawa and Yuichiro Morimitsu, Sumitomo Seika Chemicals Co., Ltd.

Described here are two acrylic rheology modifiers for novel thickening properties in formulations. A pre-neutralized carbomer is shown to impart a lighter, smoother texture than traditional carbomer while increasing process flexibility. In addition, a new associative acrylate/C10-30 alkyl acrylate crosspolymer exhibits thickening in high electrolyte media, acts synergistically with surfactants, and facilitates the dispersion of fillers.
