Overview
Ascorbyl Palmitate is the fat-soluble form of Vitamin C, created by binding ascorbic acid with palmitic acid. It supports antioxidant protection in lipid phases, helping formulations maintain integrity when exposed to oxygen, light, and heat during production or storage.

Applications & Formulation
Anti-Aging Serums: Recommended dosage of 0.5%–2.0% in anhydrous or oil-based formulations.
Emulsions & Creams: Inhibits lipid phase oxidation to prevent rancidity and yellowing in formulas with high unsaturated plant oil content.
Sun Care & Lip Balms: Prevents oxidative degradation of UV filters and carrier oils in anhydrous stick applications.
Hair & Scalp Treatments: Provides thermal and oxidative protection calibrated for sensitive scalp and hair conditioning oil lines.
Industrial Customization Options
Process-Specific Grain Sizing
Offers selectable particle distribution ranges (80–120 mesh, 120–200 mesh, and micronized <20μm) to match different shear systems and mixing conditions, reducing dispersion time in oil phases.
Traceable Regulatory Labeling
Provides configurable labeling formats, including OEM private label, neutral export labeling, and fully GHS-compliant warehouse labels, with optional integration of internal SKU barcodes, batch IDs, and scanning systems for automated inbound QC workflow.
Specification Monograph Control
Offers selectable specification control levels, from standard commercial range to tightened internal control protocol, limiting batch-to-batch assay variance within defined thresholds to ensure consistent emulsification behavior.
Packaging & Handling Configuration
Available in 25 kg standard fiber drums or customized 1 kg / 5 kg / 10 kg sub-packaging options, with optional nitrogen flushing, anti-static liners, and moisture-barrier reinforcement to maintain stability during long-distance shipping and storage.
Commercial Terms
Standard Packaging: 25 kg fiber drums lined with double PE bags (Nitrogen-blanketed packaging applied during warehouse sealing to protect stability).
MOQ Tiers: 25 kg for commercial validation, 100 kg for standard cargo shipments, and 1 metric ton for bulk contract pricing.

FAQ
Q: What is the typical lead time stability for repeat orders?
A: For repeat production lots under the same specification, lead time is typically more predictable because raw material sourcing and production scheduling are standardized in advance, especially for contract or framework orders.
Q: How do you ensure the material will not vary across different production campaigns?
A: Each production campaign follows locked process parameters and controlled reaction conditions, with batch release tied to internal QC thresholds to minimize variability between manufacturing runs.
Q: What level of technical support is available after purchase?
A: Technical support is typically focused on troubleshooting dispersion behavior, formulation compatibility in oil systems, and scale-up guidance between pilot and production stages.
Q: What payment terms are typically available for international orders?
A: Standard terms are usually T/T in advance for first cooperation orders. For established customers, partial deposit with balance before shipment or monthly settlement under framework agreements may be available, depending on credit evaluation.
Q: What documents are typically provided for customs clearance and import processing?
A: Standard shipment documentation includes Commercial Invoice, Packing List, Bill of Lading or Air Waybill, and Certificate of Analysis (COA).
