Wholesale Cosmetic Grade L-Ergothioneine 99% 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
1.Superior Antioxidant Capacity:
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.
2.Mitochondrial Protection & Anti-Aging:
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.
3.Stable & Light-Resistant:
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.
4.Gentle & Skin-Friendly:
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.
5.Synergistic Enhancement:
When combined with other antioxidants (e.g., ferulic acid, glutathione) or peptides, it doubles the anti-aging and protective effects of the entire formulation.
Product Application
1.Skincare Formulations (Core Application):
a.Daily protective products:
Toners, moisturizers, sunscreens (boosts UV damage resistance, prevents photoaging).
b.Anti-aging treatments:
Serums, ampoules, overnight masks (targets fine lines, dullness, and skin sagging caused by oxidative stress).
c.Sensitive skin care:
Calming lotions, post-sun repair products (soothes inflammation, strengthens fragile barriers without irritation).
d.Professional salon products:
Custom facial masks, anti-aging peels (enhances the efficacy of other active ingredients like vitamin C and peptides).
