Results and discussion

Results:

There were no deaths, and only 12 of the treated cases were classified as 'major outcome'. Virtually all the reports involved accidental exposure. The compositions of the cleaning preparations, routes of exposure, and clinical descriptions were not provided

Executive summary:

EFFECTS ON HUMANS

 Summary

 Human skin can tolerate contact with solutions of up to 1% LAS for 24 h with only mild irritation. Like other surfactants, LAS can deliapidate the skin surface, elute natural moisturizing factor, denature the proteins of the outer epidermal layer, and increase permeability and swelling of the outer layer. LAS do not induce skin sensitization in humans, and there is no conclusive evidence that they induce eczema. No serious injuries or fatalities have been reported following accidental ingestion of LAS-containing surfactant preparations.
