Cetyl tranexamate hydrochloride  (Synonyms: TXC hydrochloride)

Cetyl tranexamate (TXC) hydrochloride is an ester derivative of Tranexamic acid (HY-B0149). Cetyl tranexamate hydrochloride is an inhibitor of fibrinogen activation and can reduce the production of fibrinogen in keratinocytes induced by ultraviolet rays or damage, indirectly inhibiting the melanin production pathway. Cetyl tranexamate hydrochloride also targets melanin (dark spots) and hemoglobin (red spots), reducing vascular dilation and pigmentation by inhibiting inflammatory mediators (such as prostaglandins, platelet activating factors). Cetyl tranexamate hydrochloride can be used as a cosmetic ingredient and is suitable for epidermal pigment disorders such as photoaging, post-inflammatory hyperpigmentation (PIH), and melasma^[1].
