Description of key information

No effects up to the limit of water solubility (WS < 0.15 mg/L; OECD 201).

Key value for chemical safety assessment

Additional information

One experimental study investigating the toxicity of 1,2,3-Propanetriol, homopolymer, diisooctadecanoate (CAS 63705-03-3) to algae is available (BASF SE, 2013). The study was conducted according to OECD 201 under GLP conditions. Pseudokirchneriella subcapitata was exposed to six nominal concentrations (1.0, 3.2, 10, 32, 100 and 320 mg/L.), which were prepared as Water Accommodated Fraction (WAF), in a static test for 72 h. No effects on growth rate were observed up to the highest test concentration resulting in an EC10 (72 h) > 320 mg/L (nominal). Based on this result it can be concluded that no toxicological effects on aquatic algae are expected up to the limit of water solubility for 1,2,3-Propanetriol, homopolymer, diisooctadecanoate.
