Frequently Asked Questions
Q1: What is Sodium Ascorbyl Phosphate Powder?
A1: It is a stable, water-soluble derivative of Vitamin C (L-ascorbic acid) manufactured via high-efficiency catalyzed phosphoric acid esterification. It serves as an effective whitening and antioxidant agent in cosmetic formulations.
Q2: What is the purity and assay value of this product?
A2: Our Sodium Ascorbyl Phosphate has an assay purity of ≥95.0% (with typical results reaching up to 99.6%), and a total Vitamin C content of ≥45.0%.
Q3: How stable is Sodium Ascorbyl Phosphate compared to pure Vitamin C?
A3: Unlike pure Vitamin C (L-ascorbic acid) which oxidizes rapidly in water and light, Sodium Ascorbyl Phosphate is highly stable and resistant to discoloration and degradation, making it ideal for cosmetic formulations.
Q4: What are the storage requirements to maintain shelf life?
A4: It should be stored in a cool, dry, and well-closed place at a constant low temperature, protected from direct sunlight, heat, and moisture. Its shelf life is 2 years under proper storage conditions.
Q5: What standard packaging formats do you offer?
A5: We offer 1-5kg/bag (aluminum foil bag outer), 5-10kg/carton (carton outer), and 10-25kg/fibre drum. All packages contain double plastic bags inside to prevent moisture ingress. Custom packaging is also available on request.
Q6: Is the product GMO-free and safe for global distribution?
A6: Yes, our Sodium Ascorbyl Phosphate is completely Non-GMO, Non-irradiation, and processed under ISO compliant quality systems, making it ready for global export.
