Documented Uses

• Used as a mordant in dyeing textiles and polymers, a hardener in photographic emulsions, an oxidation catalyst, a polymerization catalyst, a curing agent for acrylamide polymers, and a tanning agent; [HSDB]
• Leather Tanning and Processing [Category: Industry]
• Photographic Processing [Category: Other]
• Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
• As mordant in dyeing; in tanning; in hardening photographic emulsions; to improve light stability and dye affinity of textiles and polymers; in catalyst for polymerization of olefins; as an oxidation catalyst.
• Basic chromium acetates are used as mordants in calico printing and worsted top printing, and also for fixing vigoureux dyes. Combinations of basic chromium(III) acetate and basic chromium(III) formate also find application in the textile industry as mordants. In addition, chromium(III) acetate is used as a starting compound in the production of organic chromium dyes.
