This product abosorbs efficien for UVA and best at wavelength of 345nm. In addition, Terephthalylidene Dicamphor Sulfonic Acid is chemically stable as hard to decompose and penetrate into skin.This UV-filter is with excellent safety profile. Widely used in various types of sunscreen products. (1) Totally Water soluble; (2) Broad UV spectrum,abosorbs excellent in UVA; (3) Excellent photo stability and hard to decompose; (4) Safety reliable.
Performance:	Terephthalylidene Dicamphor Sulfonic Acid appears to be relatively safe because is only minimally absorbed into the skin or systemic circulation. Since Terephthalylidene Dicamphor Sulfonic Acid 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, Terephthalylidene Dicamphor Sulfonic Acid may cause skin arritation/dermatitis. In its pure form, Terephthalylidene Dicamphor Sulfonic Acid 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 Terephthalylidene Dicamphor Sulfonic Acid, the culprit might be the neutralizing base rather than Terephthalylidene Dicamphor Sulfonic Acid itself. You could try a brand with a different neutralizing base.
