Stigmasterol(CAS:83-48-7)

Stigmasterol (CAS 83‑48‑7) is a natural plant sterol widely employed in the food, cosmetics, and pharmaceutical sectors. In food, it serves as a nutritional fortifier or functional ingredient added to fortified beverages, infant formula, baked goods, and dietary supplements, aiding cholesterol absorption regulation and enhancing the bioavailability of fat‑soluble vitamins; it is listed on positive food‑additive inventories in several countries. In cosmetics, its excellent skin‑penetration, moisturizing and antioxidant properties make it a common component of creams, lotions, sunscreens, and anti‑aging formulations, where it softens the stratum corneum and improves barrier function. In pharmaceuticals, stigmasterol is a key precursor for the synthesis of steroid hormones such as progesterone and progestins, as well as vitamin D₃, and it can act as an anti‑inflammatory and immunomodulatory agent in functional drugs and nutraceuticals. Additionally, it is used as a softening agent in paper, printing inks, and textile applications to enhance material flexibility and water resistance.
