historical data of reference tests approximately every 3 months since April 1988.

DOC analysis of the test substance concentration was conducted at test start and after 96 hours at the end of exposure. The DOC concentration measured in the test solution at test start was 0.04 mg/L; at test termination 0.83 mg/L were determind. In the control vessels a concentration of 2.02 mg/L at test start and 1.74 mg/L at test termination was measured. Thus, the substance can be considered as not soluble in the test medium. Therefore the evalution is based on nominal concentrations.

Additional information
In accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 read across to three structurally related sub-category members pentaerytritol tetraoleate (CAS 19321-40-5), 2,2-bis(hydroxymethyl)-1,3-propanediyl dioleate (CAS 25151-96-6) and fatty acids, C16-18 and C18-unsaturated, esters with pentaerythritol (CAS 85711-45-1)was conducted to fulfill the data requirement according to Annex VII-IX offatty acids, C16-18 and C18-unsatd., tetraesters with pentaerythritol (CAS 68604-44-4) in regard to the short term toxicity to fish,. This read-across is justified in detail in the overall summary (IUCLID chapter 6.1) and within the category justification in IUCLID Section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substances were used for the assessment. The fatty acid chain length of C16 and C18 of the read-across substances are identical to those of the target substance and all substances contain the same alcohol (pentaerythritol).
The first study with the read-across substance pentaerytritol tetraoleate (CAS 19321-40-5) was performed under static conditions and GLP according to OECD 203 (Bogers, 1997).Cyprinus carpiowas exposed to a nominal concentration of 100 mg/L. A stock solution was prepared in acetone. Blank and solvent controls were also tested. No mortalities occurred after the test duration of 96 hours resulting in an LC50 of > 100 mg/L. Therefore it can be concluded that pentaerytritol tetraoleate (CAS 19321-40-5) will not exhibit short-term effects to fish up to the limit of water solubility.
For the second read-across substance 2,2-bis(hydroxymethyl)-1,3-propanediyl dioleate (CAS 25151-96-6) a test under semi-static conditions according to ISO 7346-1 was performed (Richterich, 2008).Brachydanio rerio (new name Danio rerio) was exposed to nominal concentrations of 3000 and 10000 mg/L. The test substance was weighed directly into the vessels, filled up with water and stirred. No mortalities occurred after the test duration of 96 hours resulting in an LC50 of > 10000 mg/L (nominal). Therefore it can be concluded that 2,2-bis(hydroxymethyl)-1,3-propanediyl dioleate (CAS 25151-96-6) will not exhibit short-term toxicological effects to fish up to the limit of water solubility.
For the third read-across substance fatty acids, C16-18 and C18-unsaturated, esters with pentaerythritol (CAS 85711-45-1) a test under static conditions according to OECD 203 was performed (Muckle, 2013).Danio rerio was exposed to a nominal concentration of 100 mg/L. A water accommodated fraction (WAF) was prepared by adding the required amount of test substance to water with subsequent stirring. The lower phase was used as test medium. DOC analysis of the test substance concentrations indicated that the substance is not soluble in the test medium and the evaluation is hence based on nominal concentrations. No mortalities occurred after the test duration of 96 hours resulting in an LL50 of > 100 mg/L (nominal).
Based on the acute fish toxicity studies on read-across substance, it can be concluded that 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) will not exhibit short-term toxicological effects to fish up to the limit of water solubility.
