A stabilized aluminum/zirconium/glycine salt comprising a Betaine of
Formula I as additive: ##STR00001## in a sufficient amount to have (a)
an overall (Betaine+glycine)/Zr ratio in the range of 0.1 3.0:1, (b) a
ratio of Betaine to glycine of at least 0.001:1; and (c) sufficient
Betaine so that at least 0.1% of the ratio of Betaine+glycine is
contributed by Betaine.
