Wholesale L-Ergothioneine 99% Suppliers in China - Cosmetic Grade White Powder from Factory CAS 497-30-3
Product Introduction
Ergothioneine Powder is a naturally occurring amino acid-derived antioxidant primarily sourced from mushrooms (such as shiitake), fermented grains, and certain microorganisms. Unlike synthetic antioxidants, it is a unique “intracellular antioxidant” that can penetrate skin cells and mitochondria, where it neutralizes free radicals at the source.
Produced via advanced bio-fermentation technology, our ergothioneine powder retains high bioactivity and stability. It is a white, odorless fine powder with excellent solubility in water-based skincare formulations, making it a star ingredient for high-end anti-aging and protective skincare products.
Features
It neutralizes multiple free radicals (including hydroxyl radicals and superoxide anions) more effectively than vitamin C and E, and it does not oxidize itself after reaction—providing long-lasting protection instead of one-time scavenging.
It specifically accumulates in cell mitochondria (the "energy factory"), reduces oxidative damage to mitochondrial DNA, slows down cellular senescence, and maintains skin firmness and vitality.
Unlike vitamin C, it is not easily degraded by light, heat, or air. It remains active in skincare formulations for a long time, suitable for transparent packaging products.
Non-irritating, non-sensitizing, and compatible with all skin types—including sensitive, rosacea-prone, and post-procedure skin. It complements other active ingredients without causing conflicts.
When combined with other antioxidants (e.g., ferulic acid, glutathione) or peptides, it doubles the anti-aging and protective effects of the entire formulation.
