This class of compounds are prepared by the reaction of a carboxy functional silicone and a ethylene oxide, propylene oxide or mixtures thereof. The products provide unique surfactant properties, specifically emulsification properties for many oil phases.The compounds are useful for preparation of ultra mild products for use personal care applications for skin, hair care and related applications.Other References
