CAS No. 86404-04-8 3-O-Ethyl-Ascorbic Acid for Stable Vitamin C Skincare

Why Choose 3-O-Ethyl-Ascorbic Acid for Skincare Formulation?

Vitamin C is widely used in skincare for its antioxidant and brightening properties, but conventional ascorbic acid can be difficult to stabilize. Exposure to oxygen, light, and heat may cause oxidation and discoloration, creating challenges for cosmetic manufacturers. CAS No. 86404-04-8 3-O-Ethyl-Ascorbic Acid offers an alternative for developing vitamin C skincare products with improved oxidation resistance and formulation flexibility.

Key Benefits for Cosmetic Manufacturers

3-O-Ethyl-Ascorbic Acid is a modified vitamin C derivative designed to improve stability while retaining functional characteristics associated with vitamin C. Its properties make it suitable for brightening serums, facial creams, lotions, gels, and masks.

According to the supplied technical data, the ingredient achieved 95.5% retention after six weeks in an aqueous solution at 60°C. This accelerated test result indicates promising stability under the specified conditions, although finished products still require individual stability testing.

Its amphiphilic properties also provide formulation flexibility by combining polar hydroxyl groups with improved lipid compatibility. The reported transdermal penetration rate of approximately 58% offers another point of interest for developers evaluating vitamin C derivatives for topical applications.

Formulation Tips for Better Performance

When incorporating 3-O-Ethyl-Ascorbic Acid into skincare formulations, processing temperature, pH, and ingredient compatibility deserve careful attention. The supplied recommendations include adding the ingredient below 40°C and maintaining a formulation pH of 4.0–6.0.

Typical usage levels range from 0.5% to 2%, while higher-concentration products may use approximately 3%–5%, subject to formulation requirements and safety assessment. Sodium citrate at around 0.2% is also suggested as a stabilizing component, but compatibility testing should determine whether it is appropriate for the complete formula.

The ingredient can be combined with niacinamide, arbutin, or hyaluronic acid to develop products targeting uneven-looking skin tone, hydration, and antioxidant care. Formulators should evaluate solubility, processing sequence, pH compatibility, and long-term stability before scaling up production.

Applications Across Skincare Categories

The versatility of CAS No. 86404-04-8 3-O-Ethyl-Ascorbic Acid supports several cosmetic product concepts. Serums can emphasize concentrated brightening care, while creams and lotions combine antioxidant positioning with daily moisturization. Gels and facial masks offer alternative textures, and sunscreen or after-sun formulations may incorporate the ingredient as part of broader antioxidant-focused skincare development.

Selecting the appropriate concentration and delivery format depends on the product's intended function, the complete ingredient combination, and applicable cosmetic regulations.

How to Select a Reliable Raw Material Supplier

For cosmetic manufacturers, sourcing decisions should consider purity, batch consistency, packaging, documentation, and supply flexibility alongside price. The supplied product specification states a purity of 99%, a minimum order quantity of 1 kg, and 25 kg drum packaging.

SACH BIOTECH provides 3-O-Ethyl-Ascorbic Acid for cosmetic manufacturing, supporting the development of vitamin C serums, creams, lotions, gels, and other skincare products. Reviewing technical specifications and conducting appropriate formulation trials can help manufacturers assess whether this ingredient meets their product development and procurement requirements.
