Key Features
Minimum 98.0% Active Assay: Crystalline powder form that eliminates formulation variables caused by carrier or filler residues.
Controlled Heavy Metal Limits: Documented thresholds of Arsenic less than 2 ppm, Lead less than 5 ppm, and Mercury less than 1 ppm to ensure full compliance with EU cosmetic safety regulations.
Colorimetry-Controlled Visual Profile: White-to-off-white powder specs prevent batch-to-batch discoloration in water-based serums and emulsions.
Odourless Raw Material: Simplifies fragrance-free personal care formulations and eliminates processing costs for raw material odor masking.
Storage Performance
24-Month Retest Period
Retains ≥95% active assay for two years when maintained in factory-sealed, original double-lined packaging under 25°C.
Aqueous Phase Stability
Resists heat and aeration-induced oxidation in water-based formulas, preventing the rapid degradation and browning typical of pure L-Ascorbic Acid.
Storage Requirements
Keep tightly sealed in a cool, dry environment, protected from direct sunlight and ambient humidity.

FAQ
Q: Does SAP work in oil-based or anhydrous systems?
A: SAP is water-soluble and must be used in the aqueous phase, as it cannot dissolve properly in oil-only or fully anhydrous systems. For oil-based formulas, a suitable solubilization or emulsification system is required.
Q: How should SAP be added during manufacturing?
A: It should be dissolved in deionized water at room temperature with moderate stirring before any emulsification step. Avoid adding it directly into high-temperature phases to prevent performance loss.
Q: Is SAP compatible with common preservatives?
A: It works well with most standard cosmetic preservative systems like phenoxyethanol blends. However, strong oxidizing agents should be tested in final formulations for long-term stability.
Q: What payment terms are typically available for bulk orders?
A: For regular customers, standard terms include T/T in advance, with options for 30% deposit and balance before shipment. Long-term partners may qualify for negotiated terms such as partial credit based on annual volume and order history.
Q: How is SAP packaged and protected during international shipping?
A: SAP is typically packed in 25 kg fiber drums with double inner PE liners to prevent moisture absorption. For ocean shipments, pallets are heat-treated and combined with desiccants to ensure stability during long transit times.
