Nomination Summary for Long-chain alkylbenzenes (N95023)

Long-chain alkylbenzenes

Specific Substances: Dodecylbenzene, Nonylbenzene

Nomination Date: 03/27/1995

Nominator: Connecticut Department of Public Health and Addiction Services

Rationale: The molecules of alkylbenzenes of chain lengths of 9 or greater are of concern because of alkylbenzene spills from subaqueous power cables. Alkylbenzenes occur as a mixture of 9-15 carbon chain lengths and are used as feedstock in the production of linear alkylbenzene sulfonate-based detergents, in dielectric fluids, and other industrial/commercial applications. Believed to be high production chemicals. Literature suggests promotional effect as active promoters in skin painting studies. Common marine pollutants which have been show to bioaccumulate in shellfish which poses potential human health concern. Lack of chronic toxicity data.
