Method:
The following guidelines were followed during this study:
OECD Guidelines for Testing of Chemicals, Section 4, Number 402 "Acute Dermal Toxicity", adopted February 24, 1987. Directive 92/69/EEC, B.3. "Acute Toxicity-Dermal", July 31, 1992.
Procedure:
Five male and five female HanRcc:WIST (SPF) rats were treated with 2-(2- Vinyloxyethoxy)ethyl acrylate at 2000 mg/kg by dermal application. The test item was diluted in vehicle (PEG 300) at a concentration of 0.5 g/mL and administered at a volume dosage of 4 mL/kg. The application period was 24 hours.
