Evaluation of skin carcinogenicity of technical 2,2-bis-(p-glycidyloxyphenyl)-propane in CF1 mice. 1985

N Zakova, and F Zak, and E Froehlich, and R Hess

The carcinogenic potential of a technical-grade epoxy resin, Araldite GY 250, of which the diglycidyl ether of bisphenol A (DGEBPA) is the main component, was investigated in CF1 mice. Groups of 50 male and 50 female mice were treated for 2 yr by repeated epidermal application of a 1 or 10% (v/v) solution in acetone. The controls, 50 mice of each sex, were treated with acetone alone. The treatment had no effect on survival and no excess incidence of skin tumours occurred. A positive control group of 50 male and 50 female CF1 mice was treated by epidermal application of 2% (v/v) beta-propiolactone in acetone. In this group there was a high incidence of malignant skin tumours at the site of application and, consequently, increased mortality. Treatment with neither DGEBPA technical nor beta-propiolactone induced systemic neoplasia.

D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
