The evidence, graded

expert consensusUS safety reviewers (1994) judged ethyl hexanediol safe as a cosmetic ingredient, then used at 5% or less, and confirmed it in 2011. In pregnant rats, birth defects came only at doses that also harmed the mothers. On skin, undiluted, 1 mL per kg a day had no clear effect on the pups. The reviewers said the doses that did would take kilograms of a cosmetic. In 1991 the US EPA judged its use in insect repellent by pregnant women an unacceptable risk, and makers withdrew every repellent with it.Cosmetic 1994 · Journal of the American College of Toxicology ↗
