Product Introduction
L-(+)-Ergothioneine, known as premium cell-targeted antioxidant amino acid for high-end skincare, is exclusively produced via controlled edible mushroom fermentation by Xi'an Dowell Healthy. Unlike chemically synthesized alternatives, our EGT powder retains natural bioactivity without residual synthetic impurities, meeting EU cosmetic safety and CPNP notification standards.
This sulfur-containing imidazole-thione molecule owns a unique biological feature: human skin cells actively absorb it through the OCTN-1 transporter, then concentrate EGT inside mitochondria-the core zone where 90% of skin oxidative damage occurs. It executes multi-layer skin protection through 5 independent synergistic pathways: neutralizing ROS/RNS free radicals, chelating iron & copper metal ions to block Fenton oxidation chain reaction, stabilizing mitochondrial membrane & cellular DNA against photo damage, balancing endogenous antioxidant circulation, and maintaining stable activity under high-temperature cosmetic mixing & long shelf storage.
Visually presented as white to off-white fine crystalline powder, the raw material features complete water solubility, neutral pH property, and perfect compatibility with all water-based, emulsion, gel cosmetic systems. Our batch purity reaches ≥99% tested by HPLC strict detection, with ultra-low heavy metal and microbial limits suitable for sensitive skin, sun care, anti-aging and brightening finished cosmetics. Multiple global authoritative certifications including FDA GRAS, EFSA novel food approval, China IECIC 2021 listing, Kosher, Halal, ISO & Non-GMO certificates fully support cross-border cosmetic brand registration worldwide.

Frequently Asked Questions
Q1: What is the difference between your fermented ergothioneine and chemically synthesized EGT on the cosmetic market?
A: Our product is 100% extracted from fermented natural edible golden mushrooms, without toxic chemical synthesis raw materials and heavy catalyst residues; synthetic EGT often contains trace organic solvent residues, cannot pass strict EU cosmetic ingredient detection. Fermented EGT also retains better cell absorption activity for long-term skincare efficacy.
Q2: How long is the shelf life after opening the sealed ergothioneine package?
A: After opening the vacuum aluminum bag, seal tightly and store under 4℃ dark dry environment, the activity can remain stable for 6 months; long-term exposed to air and high temperature will gradually reduce antioxidant efficacy, we recommend sub-packaging into small sealed vials after opening.
Q3: Can ergothioneine be mixed with Vitamin C, retinol and other active ingredients in one formula?
A: Yes, our EGT owns wide pH compatibility and thermal stability, it can synergistically enhance antioxidant capacity with Vitamin C, hyaluronic acid, tranexamic acid and retinol, and reduce the irritation risk of retinol & high-concentration VC to sensitive skin. We provide free compound formula matching advice upon request.
Q4: Does ergothioneine powder cause skin irritation or allergic sensitization for topical skincare use?
A: Standard human skin irritation and sensitization clinical tests prove our cosmetic-grade EGT has mild non-irritating property; the GHS label only marks slight eye & respiratory irritation risks during raw material powder operation, finished skincare products with 0.05%-1% addition will not trigger skin allergy for normal and sensitive skin crowds.
Q5: What documents do you supply for cosmetic ingredient registration in EU & USA?
A: We provide full registration supporting files: HPLC COA, full-component MSDS, TDS, FDA GRAS certification file, EFSA novel food notification document, China IECIC listing certificate, Kosher, Halal, ISO9001 & FSSC22000 certification, which meet CPNP, FDA cosmetic raw material filing requirements.
Q6: What is the minimum order quantity for samples and formal bulk orders respectively?
A: Sample test MOQ is 500g (free 10–100g samples available); formal bulk order minimum quantity is 1kg, mass industrial production orders support 25kg fiber drum whole pallet wholesale with preferential unit price.
Q7: What delivery methods can I choose for bulk ergothioneine powder shipment? How long is the transit time?
A: Three mainstream logistics solutions: 1) DHL/FedEx express for goods under 100kg, door-to-door delivery within 3–5 working days; 2) Air freight for 100kg–1000kg goods, airport-to-airport transit time 5–7 days; 3) Sea freight for over 300kg bulk cargo, port-to-port delivery around 30 days.
Q8: Is this ergothioneine raw material allowed to be used in sunscreens and medical beauty repair products?
A: Fully permitted.
