Ecotoxicity

When evaluated as a group, the acrylate esters have similar ecotoxicity data. LC50 values in freshwater fish ranged from 1.81 and 5.2 mg/L, EC50 values in freshwater invertebrates (Daphnia magna) were between 1.3 and 8.74 mg/L, and EC50 values in freshwater algae were between 1.71 and 14.6 mg/L, respectively. Thus, effect values were all in the same range of concentrations with Daphnia magna as the most sensitive freshwater species by a narrow margin. A 21-day chronic life-cycle study with Daphnia magna is available with ethyl acrylate with a respective NOEC of 0.19 mg/L, and another with n-butyl acrylate with a NOEC of 0.136 mg/L. In addition, several NOEC values from studies in algal species are available ranging from 0.45 to 3.85 mg/L.

Environmental Fate

In contact with water, Isobutyl acrylate will hydrolyze slowly. Photodegradation in air will proceed slowly, too. In water, sewage treatment plants and soil rapid degradation is expected, since i-BA was readily biodegradable in an OECD 310-Screening test. Based on an experimental log Pow and calculated BCF, a potential for bioaccumulation is not to be expected. Adsorption of isobutyl acrylate to the solid soil phase is not expected.. Fugacity model calculation (Mackay Level I) revealed the atmosphere as the main target compartment for distribution which is also indicated by the substance's physicochemical properties.

Human Health Effects

Acute Toxicity; Iso-butyl acrylate is of low toxicity after a single ingestion. iBA is of moderate toxicity after a short-term inhalation and after short-term skin contact.; Oral: LD50 = 4895 mg/kg bw (rat); Dermal: LD50 ca. 793 – 4000 mg/kg bw (rabbit); Inhalation: LC50 = 10.5 mg/L (rat, 4h); Irritation/Sensitization; Iso-butyl acrylate is irritating respiratory system and skin. iBA is suspected to be a skin sensitizer, based on the structural similarity to n-butyl acrylate.; Repeated Dose Toxicity; No repeated dose toxicity studies are available with iBA; therefore data of the structural analog n-butyl acrylate are taken to assess toxicity after repeated exposure.
