  • Patent number: 10336776
    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.

  • Patent number: 5237035
    Abstract: The present invention relates to a series of novel silicone phospholipid polymers which are highly lubricious, produce high levels of copious foam, have low irritation properties and are film formers when applied to hair and skin. The compounds, because they are based upon terminal dimethicone copoylols make flat polymers when phosphated and derivatized. As will become apparent, the polymers of the present invention will orientate themselves into planar sheets, silicone on one side of the plane, fatty portion on the other side in aqueous and other solutions. These flat polymers have the unexpected property of producing non-occlusive films when applied to hair skin and fiber.
