Patent number: 6238657Abstract: Three-dimensional silicone elastomers having polyether and higher alkyl functionality in their molecules form networks of crosslinked linear siloxanes with polyether and olefin containing repeating units, and these silicone elastomers can be used as emulsifiers for making O/O and three-phase aqueous emulsions. One of the oil phases is a silicone oil, while the other oil phase is an organic oil such as mineral oil or castor oil. These emulsions of two and three mutually insoluble liquids are useful in personal and health care applications.Type: GrantFiled: July 12, 1999Date of Patent: May 29, 2001Assignee: Dow Corning CorporationInventors: Zuchen Lin, William James Schulz, Jr., Janet Mary Smith
