Toxicological evaluation of commercial alkyldimethylamine oxides: two-year chronic feeding and dermal studies

Chronic feeding and dermal studies were conducted with commercial alkyldimethylamine oxides (ADAO) in rats and mice. Rats were dosed with 0.01, 0.1, or 0.2% w/v ADAO (on a 100% active basis) in their diet for 104 weeks. Mice were exposed to ADAO via a dermal application of 0.1 ml of an aqueous solution of ADAO at concentrations of 0.05, 0.13, or 0.26% w/v ADAO (on a 100% active basis) once daily three times per week for 104 weeks. No compound-related carcinogenic effects were observed in either chronic test.
