1. What is 3-O-Ethyl Ascorbic Acid?

3-O-Ethyl Ascorbic Acid is a highly stable and oil-soluble derivative of Vitamin C (L-Ascorbic Acid). It is created through a targeted etherification process at the third hydroxyl group of the ascorbic acid molecule. This modification dramatically enhances its stability against oxidation (from light, air, and heat) and improves its skin penetration compared to pure Vitamin C. For B2B clients in the cosmetic and personal care industry, a reliable 3-O-Ethyl Ascorbic Acid manufacturer is essential for sourcing a potent, effective, and formulator-friendly active ingredient for advanced skincare solutions.

3. What Defines the Best 3-O-Ethyl Ascorbic Acid? A B2B Buyer’s Guide

のために 国際的 cosmetic brands and 輸出業者, the “best” product is defined by its ultra-high purity, brilliant white color, low odor, proven stability, and the supplier’s technical data confirming its efficacy and compatibility.

• 主な成分と効能： Premium 3-O-Ethyl Ascorbic Acid is a high-purity synthetic compound (e.g., ≥98% or cosmetic grade). Its scientifically validated benefits include:

  • Superior Stability: Highly resistant to oxidation, remaining effective in formulations far longer than pure L-ascorbic acid, even at neutral pH. This eliminates the need for highly acidic formulas.

  • Effective Skin Brightening & Anti-Pigmentation: Inhibits the enzyme tyrosinase, effectively reducing melanin production and helping to fade dark spots, hyperpigmentation, and achieve a more even skin tone.

  • 強力な抗酸化保護： Neutralizes free radicals generated by UV exposure and pollution, protecting skin cells from oxidative damage and preventing signs of photoaging.

  • Collagen Synthesis: Boosts collagen production, helping to improve skin firmness and reduce the appearance of fine lines and wrinkles.

  • (Compliant for use in cosmetic formulations globally. Not typically used in dietary supplements.)

• 原産地と品質: Our product is synthesized in a cGMP-compliant environment from high-purity starting materials, ensuring a consistent, high-quality, and contaminant-free ingredient.

• 使用方法と投与量:

  • 一般的な用途: Incorporated into serums, creams, lotions, essences, ampoules, and brightening treatments.

  • 推奨用量: Effective in formulations at concentrations typically between 0.5% and 3%. It is compatible with a wide pH range and is oil-soluble, offering formulation flexibility.

• 対象者: Formulators developing anti-aging skincare, brightening and whitening products, antioxidant serums, and general rejuvenating cosmetics.

• 注意事項と副作用:

  • 予防： Generally well-tolerated and considered non-irritating, making it suitable for sensitive skin types. It is much less acidic than pure Vitamin C.

  • 副作用: Rare. Significantly less likely to cause the stinging or irritation associated with low-pH L-ascorbic acid formulas.

5. 詳細な製品仕様（COA）

Every batch is accompanied by a comprehensive Certificate of Analysis (COA) to guarantee it meets the stringent standards of the cosmetic industry.

6. 生産工程と品質管理

Our production involves the chemical synthesis of 3-O-Ethyl Ascorbic Acid from pharmaceutical-grade L-Ascorbic Acid. The process typically involves protecting the sensitive enediol structure of ascorbic acid, followed by a controlled etherification reaction at the third hydroxyl group using ethanol. After the reaction is complete, the protecting groups are removed, and the crude product undergoes a meticulous multi-stage purification process, including crystallization and washing with specific solvents, to obtain the final pure, crystalline powder.

私たちの 品質管理 is integrated into every step. It starts with qualifying all raw materials, especially the L-Ascorbic Acid source. In-process controls monitor the reaction progress and the selectivity of the etherification to minimize by-products. The final product is rigorously analyzed. 高速液体クロマトグラフィー（HPLC） with UV detection is the primary method for quantifying the 3-O-Ethyl Ascorbic Acid content and assessing chemical purity, ensuring the absence of unreacted starting materials or synthesis impurities. FT-IR Spectroscopy confirms the molecular identity and the successful etherification. We also employ ICP-MS for sensitive heavy metal detection. This multi-tiered QC protocol guarantees a product that is pure, safe, stable, and effective for cosmetic formulations.

7. アプリケーションシナリオ

3-O-Ethyl Ascorbic Acid is a premier ingredient specifically for the cosmetics industry:

• Skincare: The primary application. Used in a vast array of products including facial serums, anti-aging creams, whitening/ brightening lotions, eye treatments, and day creams with antioxidant protection.

• ヘアケア： Incorporated into scalp treatments and hair serums for its antioxidant benefits and potential to improve scalp health.

• Cosmecuticals: A flagship active in products marketed for their clinically proven efficacy in treating hyperpigmentation and photoaging.

8. 健康上の利点、研究、イノベーション

The primary advantage over pure Vitamin C is its stability and skin permeability. Its mechanism of action remains the same once it penetrates the skin and is believed to be converted into active L-ascorbic acid. It effectively inhibits tyrosinase activity and scavenges free radicals. Current research frontiers are focused on further enhancing its delivery into the skin using nanoencapsulation technologies and exploring its synergistic effects with other actives like Vitamin E, ferulic acid, and other antioxidants. The main チャレンジ for manufacturers is achieving a very white color and minimizing any yellow tinge, which is a sign of potential degradation or impurities. At Zhonghong, our 革新 lies in our patented purification process that delivers a consistently white powder, providing our B2B partners with a superior, aesthetically perfect ingredient for their premium formulations.

9. FAQ – よくある質問

Q: How does it compare to L-Ascorbic Acid in terms of efficacy?
A: While L-Ascorbic Acid is the gold standard, its instability is a major drawback. 3-O-Ethyl Ascorbic Acid offers very comparable efficacy in terms of brightening and antioxidant benefits but with vastly superior stability, easier formulation, and better skin tolerance.

Q: Can it be used in aqueous formulations?
A: It is inherently oil-soluble. For water-based formulas, it requires the use of solubilizers or can be incorporated into oil-in-water emulsions. Its stability allows for a broader pH range than L-ascorbic acid.

Q: 通常の保存期間はどれくらいですか?
A: The raw material powder has a shelf life of 24 months when stored in a cool, dry place away from light and moisture. Its stability in a final formulation is significantly higher than that of products containing pure L-ascorbic acid.

Q: Do you offer samples for our product development and stability testing?
A: もちろんです。 無料サンプルハーブエキス and active ingredients to qualified businesses for evaluation and compatibility testing in their labs.

Q: What packaging do you use for international export?
A: We use sealed, double-layer plastic bags with desiccant inside foil-lined cardboard drums to protect the product from moisture and light during transit, ensuring it arrives in perfect condition.
