Abstract
This invention concerns the utilization of salts of alpha hydroxy carboxylic acids as stabilizers toward aging, boiling and dilution of aqueous aluminum acetate solutions. It also utilizes basic aluminum halides, other than fluorides, having the formula Al.sub.2 (OH).sub.6-m Cl.sub.m where m=1-5 or the formula Al(OH).sub.3-n Cl.sub.n where n=1-2, as starting aluminum raw material. The produced solutions are basic aluminum acetates with a pH that ranges from 2.0-7.0.
