Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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

For the structurally related n-butyl acrylate a NOEC of 0.136 mg/L was determined: NOEC (reproduction) = 0.136 mg/L (Daphnia magna, OECD 211, semi-static).

Additional information

There are no data on long-term toxicity towards invertebrates for Isobutyl acrylate. But for the structurally related n-butyl acrylate a 21-day chronic toxicity study is available (BASF SE 2009).

 

A 21-day Daphnia magna Reproduction Test sponsored by The Acrylate REACH Task Force was performed with n-butyl acrylate under semi-static conditions in accordance with OECD TG 211 and GLP regulations (BASF SE, 2009). Nominal test concentrations were 0, 0.1, 0.22, 0.46, 1.0, and 2.2 mg/L. Since the mean values of n-Butyl Acrylate in M4-medium were found to be in the range of 9.3 – 80.0 % of the nominal concentrations, the effect concentrations were based on the time-weighted mean analytically detected concentrations. The most sensitive effect values were concerning reproduction: NOEC (reproduction): 0.136 mg/L; LOEC (reproduction): 0.457 mg/L. Survival of the parent or young daphnia was not affected, but the growth of the parent animals: NOEC (body length): 0.457 mg/L; LOEC (body length): 1.226 mg/L.
