Hydroxypropyl Starch Phosphate is used in personal care cleansing systems. It provides benefits in surfactant systems on feel and foam quality, but it is difficult to stabilize in these systems. This invention now allows stabilizing Hydroxypropyl Starch Phosphate in surfactant systems and additionally using its thickening capabilities as well. Unexpectedly, small amounts of STRUCTURE® Plus thickener (Acrylates/Aminoacrylates/ C10-30 Alkyl PEG-20 Itaconate Copolymer) stabilize Hydroxypropyl Starch Phosphate and exhibit thickening synergies with this starch. Additionally, these systems exhibit a high salt tolerance, which is important in cleansing applications.
