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

In accordance with section 3 of Annex XI of legislation EC1907/2006, the study does not need to be conducted. The use of butyl acrylate as a monomer, almost exclusively in closed systems for the production of polymers, indicates that environmental exposure would be limited. The volatility of n-butyl acrylate provides for volatilization of any releases to the air. Butyl acrylate is slowly photodegradable and readily biodegradable, and accidental releases to the environment would not result in accumulation or persistence. The relatively high water solubility and corresponding low log Kow indicate that no bioaccumulation potential exists.
In order to assess long-term toxicity towards aquatic organisms, a 21-day chronic life-cycle study with Daphnia magna was conducted by BASF SE (2009).

Key value for chemical safety assessment

Additional information

The sole use of the butyl acrylate monomer is as a chemical intermediate in the production of polymeric resins (emulsion polymers) with other monomers such as acrylic acid and its salts, amides, esters, methacrylates, acrylonitrile amongst others. Butyl acrylate is handled primarily, if not exclusively, in closed systems.This use of butyl acrylate as a monomer for the production of copolymers in closed systems indicates that environmental exposure would be limited. The volatility of butyl acrylate provides for volatilization of any releases to the air. Butyl acrylate is slowly photodegradable and readily biodegradable, and accidental releases to the environment would not result in accumulation or persistence. The relatively high water solubility and corresponding low log Kow indicate that no bioaccumulation potential exists.

Acute effects levels were in the same range of concentrations for all three trophic levels, i.e. between 1 and 10 mg/L. In order to assess long-term toxicity towards aquatic organisms, a 21-day chronic life-cycle study with Daphnia magna was conducted by BASF SE (2009).
