legal entity composition of the substance
State / form:
liquid
>= 70 - <= 100 % (w/w)

Composition 1
Reference substance:
Composition 1
Reference substance:
Composition 1
This impurity is considered relevant for the classification and labelling of the substance
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 >2000 mg/L (Fish LC50 = 2,400 mg/L, Daphnia EC50 = 7,060 mg/L, Algal ErC50 = 2,512mg/L). Consequently, in accordance with Column 2 of REACH Annex IX, 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.
