Sodium Ascorbyl Phosphate

Sodium Ascorbyl Phosphate (SAP) is a naturally occurring water-soluble derivative of vitamin C. It is the most stable form of vitamin C, which means it does not oxidise. Sodium Ascorbyl Phosphate (SAP) is an antioxidant that reduces oxidative stress by neutralising free radicals, effectively slowing the ageing process and slowing the formation of fine lines and wrinkles.  SAP has the ability to penetrate the epidermis without causing irritation.

Vitamin C in its pure, active form is known as ascorbic acid. Sodium Ascorbyl Phosphate is a vitamin C derivative that gets converted to ascorbic acid in the skin. Vitamin C is notoriously unstable, particularly when exposed to light and air. On the contrary, Sodium Ascorbyl Phosphate is a significantly more stable derivative of Vitamin C, and maintains its effectiveness over time, even when exposed to environmental stressors.SAP is also generally gentler on the skin, making it a better choice for those with sensitive skin or who have had negative reactions to ascorbic acid in the past.Sodium Ascorbyl Phosphate has also shown notable sebum-regulating and anti-acne properties, which are less well-established with pure ascorbic acid.

Key Technical Parameters:

Benifits: 

Sodium Ascorbyl Phosphate does wonders for your skin. Sodium Ascorbyl Phosphate offers several benefits for the skin as following:

• Antioxidant protection: SAP has powerful antioxidant properties, and protects the skin from free radical damage, which can lead to premature ageing.

•Collagen Production: By stimulating collagen synthesis, SAP helps to maintain the skin's elasticity and youthful appearance.

•Brightening of Skin Tone: SAP has proven effective in reducing the appearance of hyperpigmentation and improving overall skin tone.

•Sebum Regulation and Anti-acne Effects: Particularly beneficial for oily and acne-prone skin, SAP has demonstrated significant sebum-regulating and anti-acne effects in several studies.

Applications:

Lotions, Cream, Sun care and after sun products, Make up products.

Vitamin C:

Nowdays Various vitamin C derivatives are used in cosmetics for external use . Pure vitamin C, ascorbic acid or also called L-ascorbic acid (ascorbic acid) has the most direct effect.In contrast to the other variants, it does not first have to be converted into the active form. Studies show that vitamin C supports collagen synthesis and fights free radicals. It is also effective against acne and age spots by inhibiting tyrosinase. However, ascorbic acid cannot be processed into a cream because the active ingredient is too susceptible to oxidation and decomposes quickly. Therefore, preparation as a lyophilisate or administration as a powder is expedient.

In the case of a serum containing ascorbic acid, the formulation should have a strictly acidic pH value to ensure the best possible penetration into the skin. The administration should be an airtight dispenser. Vitamin C derivatives that are less skin-active or more tolerable and that remain stable even in cream bases are particularly suitable for sensitive skin or the thin eye area.

It’s well known that a high concentration of an active ingredient does not mean a better care effect. Only the careful selection and the formulation adapted to the active ingredient ensure optimal bioavailability, good skin tolerance, high stability, and the best possible product performance.
