- Details on sampling:
- - Concentrations:
- Sampling method: Samples were collected on Day 2 of dry mixing, Day 6 of hydration equilibration, Day 0, prior to the addition of worms for the control and treatment and at test termination (Day 14).

Description of key information
Key value for chemical safety assessment
Additional information
Since no studies investigating the toxicity of Pentaerythritol, mixed esters with linear and branched fatty acids to soil macroorganisms are available, in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5 a read-across to the structurally related source substance Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) was conducted. The target substance is characterized as a tetraester of pentaerythritol and linear and branched fatty acids. Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) is a tetraester of C5/C7/C9/C10 with pentaerythritol. All substances share similar physico-chemical properties, only differ in the distribution of chain lengths of the fatty acid and do not share any functional group which might increase aquatic toxicity the read-across is suitable to investigate the aquatic toxicity using read-across.
This read-across is justified in detail in the overall summary (IUCLID Section 6.1) and within the analogue justification in IUCLID Section 13.
A study with the source substance Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) was conducted according to OECD 207 under GLP conditions (Kelley, 2013). Eisenia fetida was exposed to a test concentration of 1000 mg/kg dw in artificial soil for 14 d. Mortality was recorded at the end of the study. 100% survival was observed in both the control group and treatment group resulting in a NOEC (14 ) for mortality of≥1000 mg/kg dw.
Based on the available results from structurally related source substances (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) which are characterized by a similar ecotoxicological profile and comparable structure, it can be concluded that no effects on earthworms are expected for Pentaerythritol, mixed esters with linear and branched fatty acids.
