Abstract
The invention relates to a series of novel quaternized silicone fluorinated dimethicone copolyol phosphates. This class of compounds are outstandingly mild detergents and emulsifiers that provide breathable barriers when applied to hair and skin. These emulsions allow for delivery of barriers to the skin that allow for the passage of water and air through the barrier, but do not allow for the passage of oils. The compounds of the present invention are prepared by reacting a the aqueous salt a fluoro dimethicone copolyol phosphate disclosed in U.S. Pat. No. 6,087,517 with a 3-chloro-2-hydoxypropyl-quaternary compound.
