Abstract
The invention relates to a series of novel silicone alkoxylates a process for their preparation and the application of these materials as emulsifiers for a variety of oil phases. 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.
