Justification:

 

The results of an OECD Guideline 302 B (Inherent biodegradability: Zahn-Wellens/EMPA Test) concluded that 1, 3- Propanediol, 2, 2- bis(hydroxymethyl) - , allyl ether is not readily biodegradable. Further information is required until a conclusion can be made on P properties. Simulation testings on ultimate degradation in surface water (OECD 309) has therefore been proposed. 

A Bioconcentration study on the Primary Components of Allyl Pentaerythritol (APE) in Fish: Aqueous Exposure Test OECD 305-I was performed where, the BCF of 3 major constituents of APE was calculated. The highest BCF (BCF_kinetics: 120 Lkg^-1 , BCF_{steady state}: 117 Lkg^-1) was obtained from Pentaerythritol tetraallyl ether which is the contributes 9.5% of the total APE. The study result shows that this substance is not Bioaccumulative (B) neither very Bioaccumulative (vB) and do not pass the criteria of B and vB according to ANNEX XIII of the REACH guidance document.

Short-term ecotoxicology data are available, showing L(E)C50 values of 52 mg/L (fish, 96-h LC50), 69.9 mg/L (Daphnia, 48-h EC50) and >100 mg/L (algae, 72-h EC50). Long-term ecotoxicity data are not available. Based on available short-term ecotoxicity data, the substance does not meet the criteria to be considered potentially toxic (T) (i.e. L(E)C50 values are not <0.1 mg/l). It is therefore concluded that 1, 3- Propanediol, 2, 2- bis(hydroxymethyl) - , allyl ether is not T under PBT.
