从China供应商批发进口3-O-Ethyl-L-Ascorbic Acid — FOB条款

3-O-Ethyl-L-Ascorbic Acid (INCI: 3-o-ETHYL ASCORBIC ACID) is a next-generation vitamin C derivative supplied by Zhenyibio Technology Inc. from their facility in Xi'an, Shaanxi Province, China. The material presents as a white crystalline powder with molecular formula C8H12O6 and molecular weight of 204.18 g/mol. The supplier specifies minimum purity of 99% and identifies the product under CAS number 86404-04-8 and EINECS number 617-849-3. This derivative was developed to overcome the stability limitations of ascorbic acid in cosmetic formulations, offering improved resistance to oxidation, heat, and light degradation during manufacturing and shelf life.

The ethyl ether modification at the 3-position of the ascorbic acid ring confers both lipophilicity and enhanced chemical stability compared to unmodified L-ascorbic acid. This structural change allows the molecule to penetrate the stratum corneum more effectively while resisting the oxidative browning and pH-dependent instability that limits native vitamin C utility. In cosmetic applications, the material functions as a melanogenesis inhibitor, collagen synthesis promoter, and free-radical scavenger through ROS reversal. The supplier notes particular efficacy against inflammatory cytokines including IL-6, with application in anti-aging and brightening formulations at typical use levels of 0.5% to 2.0% in finished products.

Primary buyers include cosmetic contract manufacturers, skincare brands, and personal care formulators targeting the premium brightening and anti-aging segments. The material serves serums, ampoules, creams, and emulsion systems where color stability and formulation compatibility are critical. Zhenyibio Technology Inc. packages this active in 1kg aluminum foil bags for sampling and development quantities, and 25kg fiber drums for production scale. Buyers should confirm with the supplier regarding specific certificate of analysis details, storage conditions below 25°C, and any region-specific regulatory compliance documentation for their target cosmetic markets.

Zhenyibio Technology Inc. operates from No.29 Kejiliulu in the Gaoxin District of Xi'an City, Shaanxi Province, China, with postal code 71000. The supplier profile indicates a Harbor trust tier classification, with response rate and average response hours both showing zero activity. This limited engagement signal suggests buyers should anticipate longer initial inquiry turnaround and may benefit from direct follow-up communication through the listed address or alternative channels to confirm product availability and technical support capacity.

The company positions itself in the cosmetic active ingredient sector, specifically marketing vitamin C derivatives for premium skincare applications. The listing provides no stated manufacturing certifications, GMP compliance declarations, or specific quality management accreditations. Buyers should verify directly with Zhenyibio Technology Inc. whether the facility operates under ISO 22716 (cosmetics GMP), whether batch-specific certificates of analysis include heavy metals and microbial testing, and whether the company can supply regulatory documentation such as safety data sheets and cosmetic ingredient safety assessments for target import markets.
