对苯二亚甲基二樟脑磺酸(TDSA),商品名依莰舒 (Ecamsule)Mexoryl® SX,是一种水溶性的化学防晒剂。它由法国欧莱雅集团 (L'Oréal) 研发并广泛应用于其旗下防晒产品中。其主要功能是高效吸收紫外线A段 (UVA,波长320-400nm),能深入皮肤真皮层,防止皮肤光老化、色素沉着及DNA损伤。其作用机制是基于其分子结构对U光的选择性吸收。TDSA的优势包括光稳定性好(不易光照分解)、肤感相对轻盈(因水溶性可减少产品油腻感),以及安全性较高(皮肤渗透性低,刺激性小)。


Tetradecyl Sulfonate (TDSA), also known by its trade names Ecamsule or Mexoryl® SX, is a water-soluble chemical sunscreen agent.It was developed by L'Oréal in France. Its primary function is to effectively absorb UVA rays (320-400 nm), which penetrate deep into the skin's dermis and can cause skin aging, pigmentation, and DNA damage. It works by absorbing UV radiation through its specific molecular structure. Key advantages of TDSA include its good photostability (resists degradation by sunlight), relatively light skin feel (as it's water-soluble and can reduce oiliness), and high safety profile (low skin penetration and irritation potential).
