PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance, Reaction mass of 2-ethyl-2-(methoxymethyl)–propane-1,3-diol and 2-ethylpropane-1,3-diol is readily biodegradable and has a log Pow value of 0.42 (i.e. <4.5) and is therefore concluded to be not P/vP and not B/vB. Available ecotoxicology data for the substance all show L(E)C50 values >100 mg/L (Fish LC50 = 2,400 mg/L, Daphnia EC50 = 7,060 mg/L, Algal ErC50 > 100 mg/L).
In the chemical safety assessment performed according to Article 14(3) in connection with Annex I section 3 (Environmental Hazard Assessment) no hazard was identified. Therefore according to REACH Annex I (5.0) exposure estimation is not necessary. Consequently, in accordance with Column 2 of REACH Annex IX, the long term studies do not need to be conducted as all identified uses of the substance are assessed as safe for the environment. It is therefore concluded that Reaction mass of 2-ethyl-2-(methoxymethyl)–propane-1,3-diol and 2-ethylpropane-1,3-diol is not toxic (T) under PBT.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
