B2B Sourcing Guide: Elevating Skincare Stability Bulk Sodium L-Ascorbyl-2-Phosphate CAS 66170-10-3 Factory Direct
Bulk Sodium L-Ascorbyl-2-Phosphate (CAS 66170-10-3)Factory Direct
The global anti-aging and functional cosmetics market is rapidly moving away from unstable raw active ingredients. Modern formulation brands require reliable active agents that maintain structural integrity throughout their shelf life without undergoing rapid color shifts or oxidation. Sodium L-ascorbyl-2-phosphate (CAS 66170-10-3), universally known as Sodium Ascorbyl Phosphate (SAP), stands out as the premier water-soluble, highly stable Vitamin C derivative.
As an industrial-scale chemical synthesis plant, we produce and distribute premium cosmetic-grade SAP powder directly to global wholesale channels, ensuring stable batch pricing and robust contract supply chains.

Chemical Structure
Basic Chemical Info
CAS 66170-10-3 is a chemically modified ester of L-ascorbic acid. By securing the reactive enediol system of Vitamin C with a stable phosphate matrix, this molecule successfully avoids the rapid oxidation typically triggered by light, heat, and air exposure. Upon contact with the skin, localized phosphatase enzymes break down the ester bond, smoothly releasing active free ascorbic acid directly into the target dermal layers.

Application
FAQ
Q1: Can your CAS 66170-10-3 powder be used in anti-acne formulations?
Yes. Published clinical research shows that SAP possesses excellent antimicrobial activity against Cutibacterium acnes. At concentrations between 1% and 3%, it serves as an effective, gentle alternative for managing breakouts without causing the skin flaking associated with standard acids.
Q2: How does Sodium Ascorbyl Phosphate (SAP) compare to Magnesium Ascorbyl Phosphate (MAP)?
While both are highly stable, water-soluble options, SAP features a slightly higher active ascorbic acid yield per unit mass due to its molecular configuration. Furthermore, SAP is typically easier to clarify in aqueous gel bases compared to its magnesium counterpart.
Q3: What is your minimum industrial ordering quantity (MOQ)?
For standard stock specifications, our commercial MOQ begins at 25kg (1 drum). Smaller trial packages (e.g., 1kg–5kg) for laboratory validation or pilot scaling can be arranged through our sales desk.
Advanced Production Technology
Our factory runs an eco-friendly synthesis path to process bulk Sodium L-ascorbyl-2-phosphate without deploying toxic organic solvents:
[High-Purity L-Ascorbic Acid Base]
│
▼ (Phosphorylation Phase using Phosphorus Oxychloride)
[Stabilized Carboxymethyl-Phosphated Matrix]
│
▼ (Neutralization Grid utilizing Pure Sodium Hydroxide)
[Crude Sodium Ascorbyl Phosphate Liquid]
│
▼ (Multi-Stage Nanofiltration & Activated Carbon Wash)
[Fluidized Spray-Dry Air Processing]
│
▼ (Premium Dry Powder CAS 66170-10-3)
- Targeted Phosphorylation Regulating: Using advanced automated reaction systems, we selectively bind the phosphate cluster onto the C2 position of the ascorbic acid ring. This approach prevents secondary side-reactions at the C5 or C6 hydroxyl positions, ensuring consistent bio-conversion rates in final consumer applications.
- Membrane-Purified Crystallization: Our production line utilizes multi-stage nanofiltration alongside dynamic membrane systems. This allows us to separate out trace inorganic salts and unreacted phosphoric elements, yielding a highly refined powder that exhibits excellent water solubility and long-term solution clarity.
Product Advantages: Compared with Competitors
When sourcing raw cosmetic active ingredients on the global B2B market, minor structural deviations can lead to formula discoloration. Our factory-refined material provides distinct functional advantages over standard trading house options:
- Excellent pH Versatility: Standard ascorbic acid demands a highly acidic formulation window (pH<3.5), frequently resulting in skin irritation. Our SAP remains highly stable in neutral-to-alkaline aquatic bases with a pH above 7.0, making it exceptionally gentle on sensitive or acne-prone skin profiles.
- No Heat-Induced Yellowing: Many low-tier commercial alternatives begin to yellow when exposed to compounding processes that exceed 40∘C40 raised to the composed with power C
. Our strict impurity control ensures that bulk batches maintain their pure white appearance, even during long maritime transit times. - Synergistic Blending Fluidity: Through optimized spray-drying particle controls, our crystalline powder disperses quickly into aqueous solutions without clumping, dramatically cutting processing mix times for large-scale operations.
Plant Infrastructure & Scalable Production Capacities
Partnering directly with our primary industrial manufacturing plant provides your sourcing network with essential stability and regulatory support:
- Massive Output Scalability: Our specialized esterification workshops maintain a reliable annual capacity exceeding 200 metric tons, protecting your manufacturing lines from sudden raw material shortages.
- Global Regulatory Compliance: Our manufacturing complex operates under strict compliance with ISO 9001:2015, ISO 22000, and cosmetic GMP parameters.
- Complete Dossier Documentation: Every outbound commercial lot is backed by an extensive documentation bundle, containing validated batch Certificates of Analysis (COA), comprehensive Global Harmonized Safety Data Sheets (SDS), Technical Data Sheets (TDS), and matching HPLC identity validation reports.
Industrial Packaging, Sealing & Global Freight Logistics
Because Methyl L-prolinate hydrochloride is highly hygroscopic, proper sealing and climate management during transport are essential to maintain product integrity:
- Commercial Packaging Options: We ship in heavy-duty 25kg fiber drums lined with dual-layer anti-static polyethylene bags, as well as customizable 1kg aluminum foil bags for pilot manufacturing runs.
- Headspace Humidity Barriers: Every container undergoes an ultra-dry nitrogen purge and heat-sealing before palletization. This completely eliminates moisture absorption and clumping risks during long-distance ocean transit.
- Strategic Marine Port Access: Located near major global shipping ports, we provide flexible shipping terms under FOB, CFR, CIF, and DDP terms, handled by certified freight forwarders.
