Sodium Ascorbyl Phosphate (SAP)
About Sodium Ascorbyl Phosphate (SAP) in DIY Skin Care
Sodium Ascorbyl Phosphate is an active ingredient for sophisticated cosmetic skin-care products. It is a stable vitamin C derivative. It protects the skin, promotes its development and improves its appearance.
Sodium Ascorbyl Phosphate is cleaved enzymatically in the skin to release active vitamin C.
Sodium Ascorbyl Phosphate is therefore an effective antioxidant which protects the cells against damage caused by free radicals.
Sodium Ascorbyl Phosphate counteracts skin aging in promoting collagen formation.
Sodium Ascorbyl Phosphate also acts on the melanine formation process to prevent hyperpigmentation and senile keratosis. It therefore has skin lightening
Because of its wide spectrum of action, Sodium Ascorbyl Phosphate is suitable for use in a wide range of skin care products.
As an effective watersoluble anti-oxidant which is stable in cosmetic formulation it is the perfect completion to Vitamin E Acetate, which is the common oilsoluble
equivalent. The oils oluble Vitamin E Acetate together with the water soluble Sodium Ascorbyl Phosphate are the perfect anti-oxidant system in all skin-care formulations which are used against the daily environmental stress for the skin.
Other very important areas of use are sun protection formulations, antiwrinkle products, body lotions, day creams and night creams, and whitening products.

Country of origin
- Sodium Ascorbyl Phosphate (SAP) may discolor in formulations with a pH below 6, so is best used in products with a final formulation pH between 6.0 - 7.0.
- If you're having trouble dissolving Sodium Ascorbyl Phosphate (SAP) in water, warming the solution to about 40°C (104°F) will help.
- It is essential that you do NOT add the powders to the water at once, sticky lumps WILL form. It is best to sprinkle tiny amounts at a time, mix that, and then add more.
Sodium Ascorbyl Phosphate is a crystalline solid that is sensitive to heat, moisture, low pH values and heavy metals.
In the production of cosmetic care products, it is recommended to add Sodium Ascorbyl Phosphate to formulations at a low temperature ( <40°C).
It can be exposed to higher temperatures up to 80°C, but only for a short time.
The product is most stable above pH 6.5. It is recommended to use a buffer system and to add a chelating agent.
Finished formulations should be stored at a temperature below 25°C.
