Abstract
This patent relates to invert water in oil (w/o) and water in silicone (w/si) emulsions made using non PEG/PPG containing polyhydric silicone emulsifiers. The polyhydric silicone polymers are based on allyl trimethylolpropane and pentaerythritol modified organic groups and do not contain any PEG and/or PPG groups (also known as polyethylene glycol and polypropylene glycols, polyethers, polyglycols,). These emulsions show improved emulsification stability and provide a light feel compared to emulsions made with other silicone based PEG/PPG compounds which are commonly used in the field.
