Any other information on results incl. tables
Due to intensive staining by the test compound erythema was not assessable. For the purpose of calculating the primary irritation index erythema was assumed to be equal to edema based on the correlation existing (Marzulli and Maibach, Fol. Cosm. Tox. 13, 355, 1975).
