Abstract
Water soluble quaternary ammonium ethers of polysaccharides or polyols wherein the quaternary ammonium ether substituents correspond to the formula ##STR1## wherein R.sub.1 is a monohydroxylated or polyhydroxylated alkyl group containing between about one and about six carbon atoms; R.sub.2 and R.sub.3 are independently, alkyl groups containing between about one and about six carbon atoms; R.sub.4 is an alkyl group containing between about six and about 24 carbon atoms; and X is a halide, wherein the degree of substitution of said ethers ranges from about 0.001 to about 0.5. is provided. The composition have multiple uses as thickeners and are particularly suited for use in personal care products.
