Claim 6:
7. The personal care composition of claim 5, wherein the arginine is L-arginine, and the cluster is prepared by
(a) adding L-arginine under stirring to a clear solution containing 1% zirconium oxychloride, wherein the molar ratio of arginine to zirconium oxychloride is from 0.5:1 to 1:1.
(b) incubating the solution for 1 day at 50° C.; an
(c) cooling the solution down to room temperature;
wherein said molar ratios of from 0.5:1 to 1:1 demonstrates better stability in terms of gelation and flocculation under pH of 1.39, 1.73, or 2.59, than molar ratios of 2:1, 3:1 and 4:1.
