Abstract
Abstract An aqueous composition is provided which includes from about 0.1 to about 30% by weight of a quaternary ammonium functionalized phosphate ester and from about 0.01 to about 10% by weight of a cationic polysaccharide. These compositions are freeze-thaw cycle stable and exhibit unusual skin mildness properties.
