S-Acetyl-L-glutathione(CAS:3054-47-5)

S‑Acetyl‑L‑glutathione is a white to off‑white powder with good water solubility and surface activity, commonly employed as a thickening, emulsifying, stabilizing, and film‑forming agent. In the food industry it serves as an antioxidant to delay lipid oxidation and preserve color; it enhances the stability of yogurt, infant formula powders, and cold drinks, preventing ingredient separation; it shortens processing time and improves texture in baked goods and dough products; and it inhibits browning in meat and fish cakes, thereby extending shelf life. In the health‑supplement sector it acts as a nutritional fortifier supplying dietary selenium and improving amino‑acid balance, and is frequently added to functional beverages, infant formulas, and nutrition supplements. In cosmetics it functions as a moisturizing, antioxidant, and skin‑barrier repair agent, helping to fade pigmentation and achieve more even skin tone. Medically, as a precursor of glutathione it readily penetrates cells to raise intracellular glutathione levels, providing detoxification, liver protection, antioxidant, and immune‑modulating effects; it is therefore incorporated into oral health‑care products and liver‑protective formulations.
