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.

The present invention also relates to chemical compositions comprising the neutralization product of at least one amine neutralization compound (preferably, a diamine) and a carboxylic acid (preferably, a dicarboxylic acid), said amine neutralization compound comprising about 1% to about 100% by weight (of the total amount of amine neutralization containing compound) of a first amine compound and 0% to about 99% by weight of a second amine compound different from said first amine compound, said first amine compound being a polyamine containing at least one tertiary amine group and at least one quaternary amine group, said tertiary amine group of said first amine reacting with said carboxylic acid group to produce a tertiary ammonium carboxylate salt, said second amine compound containing at least one primary, secondary or tertiary amine group with the proviso that when said second amine contains only primary and/or secondary amine groups, the amount of said second amine in said amine neutralization compound is no greater than about 20% (preferably, no greater than about 10%) by weight and said carboxylic acid comprises at least about 50% by weight (more preferably at least about 75% by weight, even more preferably about 90% by weight and even more preferably about 100% by weight of a polycarboxylic acid, more preferably a dicarboxylic acid.
