Sunsafe- TDSA(30%) appears to be relatively safe because is only minimally absorbed into the skin or systemic circulation. Since Sunsafe- TDSA(30%) is stable, toxicity of degradation products is not a concern. Animal and cell culture studies indicate the lack of mutagenic and carcinogenic effects. However, direct safety studies of long-term topical use in humans are lacking. Rarely, Sunsafe- TDSA(30%) may cause skin irritation/dermatitis. In its pure form, Sunsafe- TDSA(30%) is acidic. In commercial products, it is neutralized by organic bases, such as mono-, di- or triethanolamine. Ethanolamines sometimes cause contact dermatitis. If you develop reaction to a sunscreen with Sunsafe- TDSA(30%), the culprit might be the neutralizing base rather than Sunsafe- TDSA(30%) itself. You could try a brand with a different neutralizing base.
