Overview of Terephthalylidene Dicamphor Sulfonic Acid

Terephthalylidene Dicamphor Sulfonic Acid (TDSA) is a high-performance UV filter widely used in sunscreens, cosmetic formulations, and personal care products. It provides broad-spectrum protection against UVA rays, preventing skin damage, premature ageing, and photo-induced disorders. TDSA is highly photostable, water-soluble, and compatible with various sunscreen formulations, making it ideal for lotions, creams, gels, and emulsions.

TDSA is often combined with other UV filters and stabilisers such as Ethylhexyl Methoxycinnamate, Avobenzone, Homosalate, and Octocrylene to achieve comprehensive sun protection and formulation stability.
