Description of key information
Additional information
Acute tests on all three trophic levels, as
well as a chronic test on toxicity to invertetrates, were performed to
examine the aquatic toxicity of 2,2-Dimethlypropane-1,3-diol. Algae and
Daphnia magna turned out to be the most sensitive species revealing an
ErC50 (72h) and an EC50 (48h) >500 mg/L, respectively. The actue
toxicity test with fish revealed an LC50 (96h) >10000 mg/L and in a
long-term study with aquatic invertebrate Daphnia magna a NOEC (21d) of
1000 mg/L was found.
Thus, 2,2-Dimethlypropane-1,3-diol is considered acutely not harmful to
aquatic organisms and not chronic toxic in algae and Daphnia magna.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
