The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

An acute test on Daphnia (96-h LC50 5.9 mg/L) and a chronic test on algae (3-d NOEC 2.5 mg/L) were performed to examine the acute aquatic toxicity of LAS-MIPA. The toxicity of LAS-MIPA to aquatic organisms may be described by the toxicity of LAS-Na and MIPA according to the read-across statement in which full dissociation of the LAS-MIPA in water is supported. Sufficient data are available for LAS-Na and MIPA, which should provide adequate short-term and long-term aquatic toxicity data (see read-across statement).

For LAS-Na a large number of aquatic toxicity studies are available. The EC50s and NOECs are in the same order of magnitude as those found for LAS-TEA but slightly lower. The EC50s and NOECs found in toxicity tests with TEA are higher. Therefore, a precautionary approach is taken for the derivation of the PNECaqua. The large body of long-term ecotoxicity data for LAS-Na results in a conservative estimate of the PNECaqua for the read-across analogue LAS-TEA.

On the basis of the available tests LAS-MIPA is classified as Aquatic Chronic Toxicity, Category 3.
