Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A compound selected from those of the following formulae: ##STR14## and mixtures of I and II, wherein (1) R is a C 6 to C 30 aliphatic radical, preferably alkyl or alkenyl; (2) X, Y and Z are independently selected from the group consisting of C 1 to C 6 alkyl, C 2 to C 6 alkenyl and (--CH 2 CHR 3 O--) n H groups wherein R 3 is independently selected from hydrogen and C 1 to C 4 alkyl, and n is independently an integer from 1 to 20; (3) R 2 is C 1 to C 18 alkyl, C 2 to C 18 alkenyl, benzyl or phenylethyl; (4) R 1 is hydrogen, C 1 to C 4 alkyl or C 2 to C 6 alkenyl; (5) An is a water-solubilizing anion; (6) q is an integer of 1 to 4 equivalent to the valence of the anion (An); and at least one of X, Y and Z is a (--CH 2 CHR 3 O--) n H group.
Claim 2
Dependent Claim
