Flame Retardants

Aluminum hydroxide
21645-51-2

Where is it Commonly Found?

Aluminum hydroxide is used as a flame retardant in polyethylene, acrylics, and thermosets (Sobolev and Woycheshin 1987). Major uses include vinyl and polyolefin cable jacket, elastomers, unsaturated polyester resin (Weil 2004) as well as waterborne emulsions and coatings, and in textiles. It is considered a possible alternative to decaBDE. Other than its use as a flame retardant, aluminum hydroxide is used in antacids and other medications.

HEALTH EFFECT SUMMARY

Aquatic ecotoxicity is low, and bioaccumulation is not expected to occur to any significant extent. Aluminum hydroxide has low acute toxicity via ingestion, dermal contact, and inhalation, but the dust is a respiratory irritant, with repeated exposure causing lung damage. It may also be irritating to eyes and skin. Aluminum hydroxide is not a developmental or reproductive toxicant. The American Conference of Governmental Industrial Hygienists (ACGIH) found that aluminum hydroxide was not classifiable as a human carcinogen (class A4), though this may simply indicate that data are inadequate to assess carcinogenicity (ACGIH 2008).

There have been cases of aluminum intoxication following drug therapy, particularly in children and those receiving treatment for renal failure (Rom 1992).
