[Comparison of the effects of the irritant action of different amounts of cooling mineral oil with biocides on the rabbit skin].

Effects of different concentrations of Emulgol EN-BIO C/88 oil on rabbit skin were studied. Experiments were carried out to examine oil irritancy to the skin and the inner surface of the ear skin subjected to a 24-hour closed exposure and repeated open exposure for 10 days, respectively. The data obtained have shown that 5 and 10 per cent emulsions of Emulgol EN-BIO C/88 produce mild skin irritation, while a 50 per cent emulsion and concentrate cause irritation of moderate degree. This means that the irritating potential of Emulgol depends on its concentration in oil-water emulsion. It is concluded that EN-BIO C/88 oil should be used in a 5 per cent concentration in industry.
