The present invention is directed to monomeric and polymeric compositions based upon polymeric urethane surfactants which are derived from linear, branched, or aromatic compounds of synthetic or natural origin, preferably from tertiary amines and diisocyanate compounds. The urethane polymers of the present invention may be in the form of betaines, quaternium salts, tertiary amine salts or N-oxides. The compounds of the present invention may be incorporated into personal care formulations such as cosmetics, dental care products and toiletries to improve at least one and preferably two or more characteristics of such formulations.

[ What is claimed is:] [1.]1. A compound according to the structure:R' is a C.sub.6 through C.sub.36 linear, cyclic or branch-chained saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, monomeric or dimeric, a phenyl or benzyl group or substituted phenyl or benzyl group
[ What is claimed is:] [1.]1. A compound according to the structure:R' is a C.sub.6 through C.sub.36 linear, cyclic or branch-chained saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, monomeric or dimeric, a phenyl or benzyl group or substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl or substituted alkylphenyl or alkylbenzyl group;R" is selected from a C.sub.1 through C.sub.36 linear, branch-chained or cyclic saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, monomeric or dimeric, a phenyl or benzyl group or substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl, substituted alkylphenyl or alkylbenzyl group,R'" is selected from a C.sub.1 through C.sub.36 linear or branch-chained, cyclic, saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, monomeric or dimeric or a phenyl group, benzyl group or substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl, substituted alkylphenyl or alkylbenzyl group; andR.sub.1 is selected from a C.sub.1 through C.sub.36 linear or branch-chained saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, an aromatic group, including a phenyl or benzyl group or substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl or substituted alkylphenyl or alkylbenzyl group;R.sub.2 is a free electron pair, O, a hydrogen or a quaternium group, or a mixture of hydrogen and quaternium groups, with the proviso that when R.sub.2 is H and/or a quaternium group, the nitrogen to which said hydrogen or quaternium group is bonded is positively charged and forms a salt with a negatively charged counterion T;R.sub.3 is a C.sub.1 through C.sub.36 linear or branch-chained saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, an aromatic group including a phenyl or benzyl group or substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl or substituted alkylphenyl or alkylbenzyl group;each of X and Y is independently a C.sub.1 through C.sub.36 linear, cyclic or branch-chained saturated or unsaturated hydrocarbon group which is substituted or unsubstituted, a phenyl or benzyl group or a substituted phenyl or benzyl group, an alkylphenyl, alkylbenzyl or substituted alkylphenyl or alkylbenzyl group;W is H; andn is an integer from 1 to 1000.
