<p>Quaternary complex aromatic acid salts of the formula: <CHEM> where R<1> is an alkyl group having 1 to 4 carbon atoms, which may optionally contain a hydroxyl group, R<2> and R<3> are independently alkyl or alkenyl groups, which may be optionally interrupted with ester, ether oxygen and/or amido linkages, the R<2> and R<3> groups having a total of 8 to about 30 carbon atoms, R<4> is a group as defined for R<1> or for R<2>, Z is H or OH, R<5> is alkyl, alkaryl, aralkyl, halo, alkoxy, hydroxy and m is 0-4, are stable in aqueous dispersion over a wide range of pH. The compounds are effective as emollients, lubricants and hydrophobes, and can be used in skin care and lubricant compositions, as carriers for biological actives and for other purposes. <IMAGE></p> |
