Product Description:

Sodium Ascorbyl Phosphate (SAP) is a highly stable, water-soluble derivative of Vitamin C known for its excellent antioxidant, brightening, and anti-acne benefits. Compared to pure ascorbic acid, SAP maintains its potency much longer and is gentle on the skin, making it ideal for sensitive or acne-prone skin types.

It helps even out skin tone, reduce hyperpigmentation, boost collagen production, and protect the skin from environmental stressors. SAP also exhibits antimicrobial activity against acne-causing bacteria C. acnes, making it a popular choice for brightening and clarifying skincare formulations such as serums, creams, toners, and gels.

Formulation Guidelines:

• Best added to the water phase of formulations.

• Works well with humectants like glycerin, hyaluronic acid, and soothing agents.

• Compatible with niacinamide, making it ideal for brightening serums.

• Avoid very low pH formulations; SAP requires a pH of 6–7 for stability.

• Can be combined with other antioxidants for enhanced protection.

• Dissolve fully before adding to emulsions or gels for a smooth texture.

Suitable for:

• Brightening serums

• Moisturizers

• Soothing or clarifying gels

• Anti-acne treatments

• Toners

• Masks

• Daily antioxidant creams

Storage:

Store in a cool, dry place away from direct sunlight to maintain stability.
