Aluminum salts of carboxylic acids, aluminum carboxylates, may occur as aluminum tricarboxylates (normal aluminum carboxylates), Al(OOCR)

Al(OH); and dihydroxy (dibasic) aluminum monocarboxylates, RCOOAl(OH)

. Aluminum carboxylates are used in three general areas: textiles, gelling, and pharmaceuticals. Derivatives of low molecular weight carboxylic acids have been mainly associated with textile applications; those of fatty carboxylic acids are associated with gelling salts; and more complex carboxylates find applications in pharmaceuticals. Commercial products can be combinations of mono‐, di‐, and tricarboxylates and not just the individual species. Some aluminum carboxylates of commercial interest are monobasic aluminum acetate, C
