Sodium Erythorbate

Product Description

Manufactured through advanced synthesis and strictly maintained under direct factory supply standards, our High Purity Sodium Erythorbate delivers exceptional batch-to-batch consistency for professional cosmetic formulations. As a potent stereoisomer of ascorbic acid, it functions as an advanced reducing agent that neutralizes oxidative stress and protects sensitive lipid and aqueous phases from degradation. Highly stable in aqueous solution, this critical active ingredient extends the shelf-life of finished products and preserves the structural integrity of companion molecules, thereby supporting optimal transdermal delivery.

Product Specification

• INCI Name: Sodium Erythorbate
• CAS Number: 6381-77-7
• Chemical Class: Antioxidant / Reducing Agent
• Appearance: White to yellowish crystalline powder
• Purity: ≥98.0% (High Purity)
• Solubility: Highly soluble in water

Key Benefits & Applications

• Oxidative Stress Neutralization: Efficiently scavenges free radicals and reactive oxygen species (ROS), protecting cellular components and formulation integrity from oxidative degradation.
• Formulation Stabilization: Prevents the auto-oxidation and browning of sensitive active ingredients (such as botanical extracts and vitamins), significantly extending the shelf-life and aesthetic appeal of the cosmetic base.
• Synergistic Photo-Protection: Assists in defending the skin matrix against environmental stressors when formulated with primary UV filters, enhancing overall dermal protection.
• Applications: Essential for brightening serums, advanced Vitamin C formulations, anti-aging creams, and sun protection products.

Formulation Guidelines

• Maximum Safe Concentration: Recommended usage levels typically range from 0.1% to 1.0%, depending on the specific antioxidant requirements of the matrix (Suggested).
• Solubility: Remains highly stable in aqueous solution, facilitating seamless integration into water-based serums and toners.
• Processing Phase: Recommended to incorporate directly into the aqueous phase at room temperature or during the cool-down phase below 40°C to prevent thermal degradation.
• Synergy: Combine with Ascorbic Acid (Vitamin C) to inhibit its premature oxidation and enhance sustained brightening efficacy.
