Patent number: 8124062Abstract: This invention relates to a novel class of Dimer Alkyl Silicone Polymers (DASP) and their use to provide conditioning to skin and hair. By conditioning is meant a elegant smooth skin feel, eliminating dryness and raspiness. It is thought the mechanism of action is related to the fact that the DASP compounds reduce surface tension of personal care products, providing outstanding conditioning and skin feel. The improved conditioning composition based upon a very specific class of dimer alkyl silicone polymers (DASP) that despite their solubility in oil, lower surface tension and improve conditioning of personal care products.Type: GrantFiled: August 26, 2010Date of Patent: February 28, 2012Assignee: SILTECH CorporationInventors: Anthony J.
