The authors suggest two stages of ecological and hygienic evaluation of surface active substances widely used in oil extraction. Stage 1. Toxicological-hygienic evaluation of these substances. Stage 2. Ecological-hygienic aspects of surface active substances (migration into soil, phytotoxicity, effect on the water quality and oth.). It was established at stage 1 that proxanol, proxamin, diproxamin are compounds of minor hazard (class 4 hazard). These substances belong to local skin-irritating substances. Proxanol produces skin-resorptive effects which is confirmed by clinical signs of intoxication, reduction of weight of the experimental animals.
