10g Sodium Ascorbyl Phosphate Powder (SAP)

Sodium Ascorbyl Phosphate (SAP) is one of the most reliable and scientifically respected vitamin C derivatives used in modern skincare. Unlike pure L-Ascorbic Acid, which oxidizes rapidly when exposed to air, light, water, or an unsuitable pH, Sodium Ascorbyl Phosphate was developed to deliver the long-term benefits of vitamin C while remaining remarkably stable throughout formulation, storage, and everyday consumer use.

Once applied to the skin, naturally occurring skin enzymes gradually convert Sodium Ascorbyl Phosphate into active vitamin C (ascorbic acid). This slow conversion allows the skin to utilize vitamin C over time instead of receiving a sudden burst that may quickly degrade. The result is a gentler yet highly effective form of vitamin C that is suitable for daily use and for individuals with sensitive, reactive, or acne-prone skin.

One of SAP's greatest advantages is that it performs exceptionally well in formulations with a near skin-friendly pH, unlike pure vitamin C which requires an acidic pH of around 2.5-3.5 to remain effective. This makes Sodium Ascorbyl Phosphate considerably easier to formulate with while reducing the likelihood of irritation, redness, stinging, or barrier disruption.

SAP is widely recognized for addressing multiple skin concerns simultaneously. It helps brighten dull complexions by gradually reducing excess melanin production, improving the appearance of post-inflammatory hyperpigmentation, acne marks, uneven skin tone, and sun-induced discoloration. Continuous use promotes a fresher, more luminous complexion without the aggressive peeling sometimes associated with stronger acidic vitamin C products.

Its antioxidant capability is another major reason formulators value this ingredient. By helping neutralize free radicals generated from UV exposure and environmental pollution, SAP supports healthier-looking skin and helps reduce oxidative stress that contributes to premature ageing. While it is not a replacement for sunscreen, it works exceptionally well alongside daily UV protection to provide an additional layer of defense against environmental damage.

Sodium Ascorbyl Phosphate is also valued for its ability to support collagen synthesis. Adequate collagen production contributes to firmer, smoother-looking skin and helps soften the appearance of fine lines over time. Because SAP releases vitamin C gradually, many users experience these long-term skin improvements with significantly less irritation than highly acidic vitamin C serums.

One feature that distinguishes SAP from many other vitamin C derivatives is its proven support for acne-prone skin. Scientific studies have demonstrated that Sodium Ascorbyl Phosphate possesses antimicrobial activity against Cutibacterium acnes (formerly Propionibacterium acnes), the bacteria involved in acne development. This means SAP not only helps fade acne marks but can also assist in reducing future breakouts while calming inflammation, making it particularly valuable in acne serums, moisturizers, facial gels, and clarifying creams.

Because of its excellent stability, compatibility, and broad skin benefits, Sodium Ascorbyl Phosphate has become a preferred choice in premium facial serums, brightening creams, moisturizers, toners, masks, eye treatments, anti-ageing products, and acne care formulations where long shelf life and consistent performance are essential.

INCI Name:

Sodium Ascorbyl Phosphate

CAS Number:

66170-10-3

Appearance:

Fine white to off-white crystalline powder with little to no characteristic odor.

Country of Origin:

China

Formation:

A stable, water-soluble phosphate ester derivative of L-Ascorbic Acid (Vitamin C), produced by phosphorylating ascorbic acid and neutralizing it with sodium to significantly improve stability against oxidation.

Specification:

• Cosmetic Grade
• Purity: Typically ≥95%
• Water-soluble
• Stable Vitamin C derivative
• Non-animal derived
• Suitable for vegan formulations
• Low odor
• Excellent formulation stability

Grade:

Cosmetic Grade

pH Stability:

Performs best within pH 6.0–7.5, with optimal long-term stability around pH 6.5–7.0. It remains significantly more stable than L-Ascorbic Acid across this range and is well suited for leave-on skincare formulations designed to match the skin's natural pH.

Recommended Usage Percentage:

• Daily facial products: 0.2–1%
• Brightening formulations: 1–3%
• Intensive treatment serums: 3–5%
• Professional formulations: Up to 5%, depending on formulation goals and compatibility.

Solubility:

Readily soluble in water. Insoluble in oils and non-polar solvents. Best dissolved completely in the water phase before combining with other formulation phases.

Compatibility:

Compatible with numerous cosmetic ingredients including:

• Niacinamide
• Panthenol (Vitamin B5)
• Sodium Hyaluronate
• Glycerin
• Betaine
• Allantoin
• Ceramides
• Green Tea Extract
• Centella Asiatica Extract
• Licorice Extract
• Tranexamic Acid
• Alpha-Arbutin
• Peptides
• Ectoin
• Aloe Vera Extract

Compatible with most emulsifiers, humectants, and aqueous gel systems.

Avoid prolonged exposure to highly acidic formulations (below pH 5), as this gradually reduces stability and effectiveness.

Mixing Phase & Temperature Range:

Incorporate into the water phase after complete dissolution.

For maximum stability, add during the cool-down phase below 40°C, although brief exposure up to approximately 50°C during processing is generally tolerated. Avoid prolonged heating, as excessive temperatures may gradually reduce potency.

Application:

Suitable for:

• Brightening facial serums
• Vitamin C serums
• Anti-ageing creams
• Moisturizers
• Acne treatment gels
• Facial lotions
• Brightening toners
• Facial essences
• Sleeping masks
• Eye creams
• Sheet mask essences
• Spot correctors
• After-sun skincare
• Sensitive skin formulations

Performance:

• Helps brighten dull and uneven skin tone.
• Reduces the appearance of post-acne marks and hyperpigmentation.
• Supports healthy collagen production for firmer-looking skin.
• Provides strong antioxidant protection against environmental oxidative stress.
• Helps reduce visible signs of premature ageing.
• Assists in calming inflammation associated with acne-prone skin.
• Demonstrates antimicrobial activity against acne-causing bacteria.
• Supports healthier skin barrier function with consistent use.
• Promotes smoother, more refined skin texture.
• Maintains excellent formulation stability compared to pure vitamin C.
• Suitable for long-term daily skincare without the high irritation potential of acidic vitamin C.

Storage:

Store in a tightly sealed, moisture-proof container in a cool, dry place away from direct sunlight, humidity, and excessive heat. Minimize repeated exposure to air during handling to preserve long-term stability. Properly stored material retains potency far better than pure L-Ascorbic Acid.

Shelf Life:

Approximately 24 months from the manufacturing date when stored under recommended conditions in unopened packaging.

Precaution:

• For cosmetic use only.
• Avoid inhaling the fine powder during handling and wear appropriate personal protective equipment when weighing large quantities.
• Always formulate within the recommended pH range to maintain optimal stability and efficacy.
• Conduct compatibility and stability testing when combining with new active ingredients, and perform preservative challenge testing for finished water-based products.
• Keep out of reach of children.
