Product Description

Vitamin C Cosmetic Grade Powder (Sodium Ascorbyl Phosphate) is a stable, water-soluble form of Vitamin C that works well in cosmetic formulations. Unlike other forms of Vitamin C, this one resists oxidation and retains its potency over time, so you get consistent results in your skincare products. Clinical studies have shown the effectiveness of sodium ascorbyl phosphate in improving skin health and preventing UV-induced damage.

Its fine white powder texture makes it easy to add to water-based products such as serums, gels, lotions, and toners. It brightens dull or tired-looking skin, making it a favourite for revitalising and glow-enhancing formulations. Sodium ascorbyl phosphate resists oxidative degradation, so it’s stable in formulations.

Vitamin C is known for its antioxidant properties to protect the skin from environmental aggressors such as pollution. This cosmetic grade powder also helps to even out complexion and may reduce redness and blotchiness, making it suitable for eczema and psoriasis-prone skin. It inhibits melanin production to reduce hyperpigmentation and even out skin tone. It’s also soothing and balancing, so great for oily or blemish-prone skin types. It helps to smooth out skin texture and can refresh the appearance of uneven skin tone when used regularly in skincare routines.

Why Sodium Ascorbyl Phosphate?

This form of Vitamin C is loved by formulators for its high stability and low irritation risk. Unlike ascorbic acid, sodium ascorbyl phosphate is more stable and less prone to degradation. It won’t oxidise, so your products remain effective and visually appealing.

Other forms of Vitamin C may change the colour and consistency of your formulas, but Sodium Ascorbyl Phosphate remains reliable and easy to use.

L-ascorbic acid is a powerful form of vitamin C, but less stable than sodium ascorbyl phosphate. Sodium ascorbyl phosphate is one of the most effective vitamin C derivatives available, more stable and with better skin penetration. Plus, it has a proven track record as an antioxidant ingredient in cosmetic applications and is listed in the Cosmetic Ingredient Database (CosIng) for skin conditioning and antioxidant functions.

Stable Forms of Vitamin C

When it comes to adding Vitamin C to skincare formulations, stability is key. There are several stable forms of Vitamin C available, including Sodium Ascorbyl Phosphate (SAP), Magnesium Ascorbyl Phosphate, and Ascorbyl Palmitate. These derivatives are designed to withstand heat, water, and oxygen, making them ideal for long-lasting cosmetic products.

Sodium Ascorbyl Phosphate is popular because of its high potency and deep skin penetration. It gives you the benefits of Vitamin C without the common drawbacks of irritation and rapid oxidation. Magnesium Ascorbyl Phosphate and Ascorbyl Palmitate are also great options, each with its benefits. But SAP is often preferred for its gentle nature, so suitable for sensitive skin types.

Water-Based Formulations

Because of its water solubility, Vitamin C Cosmetic Grade Powder can be added to water-based serums, gels, sprays, and creams. It blends well with hydrating actives such as Hyaluronic Acid Eco 100% Powder and Panthenol (Pro Vitamin B5) to enhance the benefits of your skincare product.

Skin Care

• Vitamin C supports collagen synthesis, making it an essential ingredient in age-defying creams, lotions, gels, and serums.

• It also supports the renewal of fibroblasts.
  
  
• It protects the cells from free radical damage as it is an excellent antioxidant that is water-soluble.
  
  
• Excellent for brightening a dull skin tone and evening out the complexion.
  
  
• At higher levels, it can be used to lighten hyperpigmentation and age spots on the skin.

Other

• Use 0.2% to 2% as an antioxidant and for age-defying products.
  
  
• Use 3% to 5% as a skin lightening active.
  
  
• Water soluble, so it cannot be used in oil-only products.
  
  
• It is heat sensitive, so it needs to be added in Stage 3 (below 40°C) and must be dissolved in something water-based first.
  
  
• The addition of Vitamin C can change the pH of the finished product.
  
  
• The ideal pH for Vitamin C (Sodium Ascorbyl Phosphate) is pH 6.5 to 7; however, it may be more relevant to change this if the preservative you are using has a defined pH of activity.
