Sodium Ascorbyl Phosphate (SAP) is a stable, water-soluble derivative of Vitamin C (ascorbic acid). It is commonly used in skincare, cosmetics, and pharmaceutical products due to its ability to deliver the benefits of Vitamin C in a more stable and less irritating form. Below is some basic information:
Chemical Properties of Sodium Ascorbyl Phosphate
- Chemical Formula: C6H7NaO9P
- Molecular Weight: 322.13 g/mol
- Appearance: White to off-white powder
- Solubility: Highly soluble in water, slightly soluble in ethanol.
Key Benefits and Functions of Sodium Ascorbyl Phosphate
- Antioxidant: Protects skin cells from damage caused by free radicals and environmental stressors like UV radiation and pollution.
- Collagen Production: Promotes the synthesis of collagen, improving skin elasticity and reducing signs of aging.
- Brightening Effect: Reduces melanin production, helping to fade dark spots and hyperpigmentation, resulting in brighter skin.
- Acne Management: Exhibits antibacterial properties, especially against Propionibacterium acnes, making it useful in acne treatments.
- Skin Soothing: Gentle on the skin compared to pure ascorbic acid, suitable for sensitive skin types.
Applications of Sodium Ascorbyl Phosphate
- Skincare Products: Found in serums, moisturizers, and sunscreens for anti-aging and brightening effects.
- Cosmetics: Used in formulations to enhance skin clarity and evenness.
- Pharmaceuticals: Occasionally used in topical formulations for dermatological benefits.
Advantages over Pure Vitamin C
- Stability: More resistant to oxidation, ensuring a longer shelf life.
- Lower Irritation: Gentler on the skin, minimizing redness and sensitivity.
- Water Solubility: Easily incorporated into aqueous-based formulations.
Storage
- Should be stored in a cool, dry place, away from light and moisture to maintain its stability.

Uses of Sodium Ascorbyl Phosphate
Sodium Ascorbyl Phosphate (SAP) is a stable, water-soluble derivative of Vitamin C commonly used in various applications, primarily in the cosmetics and pharmaceutical industries. Here are its main uses:
1. Skincare Applications
- Anti-Aging: Sodium Ascorbyl Phosphate boosts collagen production, reducing fine lines and wrinkles, and improving skin elasticity.
- Brightening Agent: It helps reduce hyperpigmentation, dark spots, and uneven skin tone by inhibiting melanin production.
- Antioxidant Protection: Protects the skin against free radical damage caused by UV rays and environmental pollutants.
- Acne Treatment: Exhibits antimicrobial properties, reducing acne-causing bacteria and inflammation.
- Moisturization: Enhances hydration and improves skin texture.
2. Hair Care Products
- Used in shampoos and conditioners to protect hair from oxidative stress and environmental damage.
- Promotes a healthier scalp and can reduce irritation.
3. Pharmaceuticals
- Found in formulations aimed at treating skin conditions like acne, eczema, or psoriasis due to its anti-inflammatory properties.
4. Food and Beverage Industry
- Occasionally used as an antioxidant to stabilize products and prevent oxidation, though less common compared to other derivatives of Vitamin C.
5. Personal Care Products
- Used in formulations of sunscreens, serums, creams, and lotions to provide additional Vitamin C benefits.
Its stability and gentle nature make Sodium Ascorbyl Phosphate suitable for sensitive skin and long-lasting formulations.
