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.
