Sodium Ascorbyl Phosphate goes by the chemical formula C6H6Na3O9P. People in personal care and health industries know it as a stable, water-soluble form of Vitamin C. Shandong Kunda Biotechnology produces Sodium Ascorbyl Phosphate using controlled synthesis from ascorbic acid and sodium phosphate derivatives, resulting in a molecule that holds the antioxidant strength of Vitamin C while offering significantly better resilience against oxidation and degradation from light and air exposure. This single element changes the shelf-life and formulation choices for anyone building topical or oral products, since so many alternatives fall apart rapidly once exposed to the elements. Many cosmetics and pharmaceutical brands depend on it as a critical raw material.
Sodium Ascorbyl Phosphate usually appears as a white or almost white crystalline powder, sometimes found in the form of solid pearls or flakes. Shandong Kunda's typical production batches show a fine, free-flowing texture, making measuring and weighing straightforward, critical during high-volume blending phases in manufacturing. This powder dissolves easily in water, forming clear to slightly hazy solutions depending on concentration. At room temperature, the density typically lands between 0.9 and 1.2 grams per cubic centimeter, a factor that helps users estimate volume and container needs for storage or transport. Its structure features a sodium salt attached directly to the ascorbate group via a phosphate linker, which acts as the backbone stabilizing the molecule against oxidation. That molecular structure not only locks in activity longer but allows the compound to serve as a more bioavailable source of Vitamin C when used in topical gels, creams, or serums, compared to plain ascorbic acid.
The HS Code for Sodium Ascorbyl Phosphate is 29362700, putting it alongside other organic compounds with pharmaceutical potential. Purity from Shandong Kunda usually climbs higher than 99% by HPLC analysis, as slight contamination can upset the stability and safety profile in end-use. The molecular weight clocks in at approximately 322.06 g/mol, key for dosing calculations and cross-checking labels for compliance. Melting point registers above 190°C, and the compound does not show significant loss on drying below 105°C—another nod to its robustness compared with unstable alternatives. Chemically, it behaves as both a reducing agent and a chelator, making it a sought-after ingredient in skin-brightening formulations and anti-aging solutions. Its reactivity also spotlights danger if mixed with strong acids or oxidizers; physical properties demand careful management throughout storage and handling.
Suppliers from Shandong Kunda deliver Sodium Ascorbyl Phosphate in multiple forms: dry powder, small pearls for precise metering, thin crystalline flakes, and sometimes as a premixed aqueous solution for direct application. Each form brings something unique—powder dissolves rapidly and stores well, while pearls can reduce airborne dust during industrial dispensing. Flakes handle static charges better and resist clumping in humid environments. As a raw material, its main job is to supply stable Vitamin C activity to whatever system it enters. In skin care, it finds its way into whitening serums, anti-blemish creams, and sun protection gels owing to its ability to fight damaging free radicals and brighten skin tone. In oral health, some toothpastes and mouth rinses deploy it to strengthen gum tissue and counteract oxidative stress caused by inflammation. Product formulators often choose Sodium Ascorbyl Phosphate over traditional Vitamin C when longevity and color stability matter; no one wants a cream that turns brown weeks after opening.
Safety sheets classify Sodium Ascorbyl Phosphate as low-risk if used according to recommended guidelines. Skin irritation studies rarely show problematic reactions at concentrations up to 10% in leave-on cosmetic products. Inhalation of powder dust requires engineering controls—good ventilation and simple masks protect workers. Despite being less hazardous than many other chemical actives, this compound reacts with strong oxidizers and acids, kicking up heat and sometimes gas, so segregated storage reduces the risk of accidental mixing. Disposal procedures call for controlled neutralization and dilution before introduction to wastewater systems, because heavy concentrations may disrupt microbial life. Readily biodegradable under standard wastewater treatments, it does not persist in the environment when handled properly. Its robust safety profile means that more personal care manufacturers now turn to it as consumer demand escalates around cleaner, skin-friendly options.
Bulk handling at Shandong Kunda involves triple-sealed, food-grade polymer drums with desiccant liners for moisture control. Warehouses require cool, dry, and dark storage—high humidity and light degrade potency over months. Large-scale buyers often demand lot-specific COAs to verify purity, density, and absence of harmful impurities like lead, arsenic, or pesticides. Safe transport regulations for this compound do not classify it as hazardous under normal shipping, but accidental release protocols sit in place to manage dust. A steady supply chain, built on secure global sourcing of both ascorbic acid and sodium phosphate, helps ensure continuous deliveries even during market turbulence. As a specialist who has watched ingredient shortages disrupt production lines, I see just how important this supply reliability remains for downstream industries relying on stable, high-grade Vitamin C derivatives.
Sodium Ascorbyl Phosphate will likely grow in both popularity and complexity. Regulatory shifts across Europe, North America, and Asia mean suppliers need regular toxicology updates to guarantee ongoing compliance. Testing for trace hazardous materials like ethylene oxide, solvent residues, or heavy metals reflects the reality that claims of “safer, cleaner, greener” ingredients require third-party validation and real transparency throughout the chain. Shandong Kunda Biotechnology regularly updates production SOPs, audits raw material partners, and pushes for documentation in every transport batch to reassure buyers and protect end-users. In an age when consumer trust can be destroyed by a single recall, meaningful certifications and robust supply-side traceability matter more than ever.
