US EPA Issues Five 'Not Likely to Present Unreasonable Risk' Findings

The US EPA has published TSCA section 5(a)(3)(C) determinations for five substances that were the subject of pre-manufacture notices (PMNs).

All were determined not likely to present an unreasonable risk based on low human health and environmental hazard.

Three of the substances carry a polymer exemption flag. This requires that they be manufactured such that they meet the exemption criteria. These substances are:

> 1,6,10-dodecatriene, 7,11-dimethyl-3-methylene-, (6E)-, homopolymer, 2-hydroxypropyl-terminated (CASRN: 1898242-86-8). The review on this substance began on 17 November 2016;

> 1,6,10-dodecatriene, 7,11-dimethyl-3-methylene-, (6E)-, homopolymer, 2-hydroxyethyl-terminated (CASRN: 2007163-32-6) – review began 17 November 2016;

> generic substituted carbomonocycle, polymer with substituted carbonomoncycles, alkyl substituted- alkanediols, alkanediol, alkanedioic acid, and dialkylene glycol – review began 24 April 2017;

The other two substances are:

> generic poly aliphatic phosphate – review began 22 June 2016;

> alcohols, C12-13-branched and linear, dimerized – review began 22 March 2017.

The agency made its determinations between 21 and 31 July.
