Abstract

A dermal penetration rate (flux), predicted from physical properties of 132 chemicals, is suggested as an index of the dermal absorption potential of industrial chemicals. The prediction is designed for organic nonelectrolytes. Two reference values are recommended as criteria for skin notation: 1) dermal absorption potential, which relates to dermal absorption raising the dose of nonvolatile chemicals or biological levels of volatile chemicals 30% above those observed during inhalation exposure to TLV-TWA only--dermal absorption of chemicals belonging to this category should be considered when data obtained by biological monitoring are interpreted; and 2) dermal toxicity potential, which relates to dermal absorption that triples biological levels as compared with levels observed during inhalation exposure to TLV-TWA only. Chemicals belonging in this category should carry a skin notation. The toxicity criteria may not be valid for chemicals whose TLVs are based on preventing irritation and discomfort.
