AccessWHITE SAP

Stabilized Vitamin C for Advanced Brightening and Antioxidant Defense

INCI Name: Sodium Ascorbyl Phosphate

AccessWHITE SAP is a highly stable, water-soluble derivative of Vitamin C that offers powerful antioxidant, brightening, and collagen-boosting benefits without the stability issues of L-Ascorbic Acid. As Sodium Ascorbyl Phosphate, it effectively brightens skin tone, fades hyperpigmentation, and provides photoprotective properties. It is an excellent choice for creating gentle yet potent anti-aging, brightening, and clarifying cosmetic products.

Solubility Notes:

Water-soluble. Add to the water phase of your formulation. For best results, maintain a final pH of 6.0–7.0 and add during cool-down (below 40 °C) to preserve stability.

Performance & Formulation Insights for AccessWHITE SAP

How Sodium Ascorbyl Phosphate Works

Sodium Ascorbyl Phosphate (SAP) is a stabilized precursor to Vitamin C. Once applied and absorbed, skin enzymes cleave the phosphate group to convert SAP into active L-Ascorbic Acid, enabling a gentler, more controlled delivery of Vitamin C’s benefits. SAP neutralizes oxidative stress from environmental aggressors, inhibits tyrosinase to reduce melanin production and fade dark spots, and serves as a cofactor in collagen synthesis to support firmness and elasticity. Additionally, SAP has demonstrated antimicrobial effects against acne-associated bacteria, offering multi-functional utility for brightening, anti-aging, and clarifying formulations.

Formulation Guidelines

AccessWHITE SAP is a fine white powder freely soluble in water, easily incorporated into the water phase of emulsions, gels, and aqueous serums. For optimal stability and to prevent discoloration, maintain a final formulation pH between 6.0 and 7.0. Add SAP during the cool-down phase (below 40°C / 104°F) to protect integrity. It pairs synergistically with other antioxidants like Vitamin E (tocopherol) and Ferulic Acid, which help regenerate antioxidant capacity and enhance overall photoprotection.

Key Formulation Benefits

  • Superior Stability: More resistant to oxidation than L-Ascorbic Acid, supporting longer shelf life and reduced discoloration.
  • Multi-Functional Efficacy: Delivers brightening, antioxidant, anti-aging, and anti-acne benefits in a single active.

Frequently Asked Questions About AccessWHITE SAP

For daily antioxidant support, use 0.2–2%. For visible brightening and anti-aging benefits, use 3–5%. Concentrations up to 10% can be used in targeted treatments, but 5% is effective for most applications.
Maintain a final pH between 6.0 and 7.0 to ensure stability and prevent discoloration.
AccessWHITE SAP is more stable and gentler to formulate with. While L-Ascorbic Acid can be more potent, it is highly unstable and requires a low pH that may irritate skin. SAP is converted to ascorbic acid within the skin, providing similar benefits with greater formulation stability and usability.
Yes. Sodium Ascorbyl Phosphate has demonstrated antimicrobial activity against acne-associated bacteria and helps reduce inflammation, making it suitable for clarifying serums and lotions.
Yes, it is highly compatible with niacinamide. When using with retinoids, many formulators apply them at different times (e.g., Vitamin C in the morning, retinol at night) to maximize efficacy, though well-designed formulas can incorporate both.
As a potent antioxidant, it helps neutralize free radicals generated by UV exposure. While not a sunscreen, it complements sun care and after-sun products to support protection against photo-aging.
