Ergothioneine (mercaptohistidine trimethyl inner salt, ergothioneine, EGT) is a compound discovered in 1909, originally found in a fungus Claviceps purpurea, pure white crystals, water-soluble, (at room temperature) Soluble 0.9mol/L), will not self-oxidize under physiological pH value and strong alkali solution. It exists in two isomers, thiol and thione forms. Ergothioneine is a natural antioxidant that can protect cells in the human body and is an important active substance in the body. Natural antioxidants are safe and non-toxic, and have become a research hotspot.

1. Used as a unique antioxidant.

2. Add to cosmetics as a skin protectant Ultraviolet UVA in sunlight can penetrate into the dermis layer of human skin, affect the growth of epidermal cells, make surface cells die, and cause premature skin aging, while ultraviolet UVB is more likely to lead to the occurrence of skin cancer. Ergothioneine can minimize the formation of reactive oxygen species and protect cells from radiation damage. Therefore, ergothioneine can be added to certain cosmetics as a skin protectant for the development of outdoor skin care products and protective cosmetics.
3. In the field of cosmetics, it can be used for anti-aging, and can be made into products such as sunscreens.
