Sodium Ascorbyl Phosphate (SAP)

Why Use Sodium Ascorbyl Phosphate?

SAP is one of the most stable and skin-compatible forms of Vitamin C available for cosmetic formulations. Unlike pure ascorbic acid, it resists oxidation and retains potency longer in water-based systems. It gradually converts into active Vitamin C on the skin, delivering antioxidant protection, brightening effects, and supporting collagen synthesis over time.

Key Benefits:

• Brightens dull or uneven skin tone
• Fights oxidative damage caused by UV and pollution
• Supports collagen production and smoother skin texture
• Gentle and non-irritating for sensitive skin types
• Helps reduce appearance of blemishes and post-acne marks

Common Applications:

• Brightening serums and lotions
• Vitamin C facial mists
• Anti-aging creams and moisturizers
• Anti-acne skincare formulations

Usage Guidelines:

• Typical usage rate: 1%–5%
• Can be added to the water phase of formulations
• pH range for stability: 6.0 – 7.0
• Compatible with other antioxidants like Vitamin E and Ferulic Acid

Formulation Tips:

• Use chelating agents (like EDTA) to improve stability
• Combine with Niacinamide or Zinc PCA for acne-prone formulations
• Avoid very low pH systems (<5) to prevent degradation
