An overview of hazard and risk assessment of the OECD high production volume chemical category-Long chain alcohols [C6-C22] (LCOH)

This review summarizes the findings of the assessment report for the category, long chain alcohols (LCOH) with a carbon chain length range of C-6-C-22 covering 30 substances, and > 1.5 million tonnes/year consumed globally. The category was evaluated under the Organization for Economic Co-operation and Development (OECD) high production volume chemicals program in 2006. The main findings of the assessment include: (1) no unacceptable human or environmental risks were identified; (2) these materials are rapidly and readily biodegradable; (3) a parabolic relationship was demonstrated between carbon chain length and acute and chronic aquatic toxicity; (4) category-specific (quantitative) structure-activity relationships were developed enabling prediction of properties across the entire category: (5) LCOH occur naturally in the environment in an equilibrium between synthesis and degradation; (6) industry coming together and sharing resources results in minimizing the need for additional animal tests, produces cost savings, and increases scientific quality of the assessment.
