Ascorbyl Palmitate Powder - Premium Grade Antioxidant from Shaanxi Nuoyuan Biotech

The Ascorbyl Palmitate Powder (CAS 137-66-6) supplied by Shaanxi Nuoyuan Biotech is of pharmaceutical quality and has a 95% purity level, as confirmed by HPLC. With a 30,000㎡ ISO 9001 certified factory, we process 20,000 tonnes of raw materials annually as a large corporation with over a decade of industry expertise.

We outperform water-soluble vitamin C in lipidic formulations because our product is a fat-soluble ester of palmitic acid and L-ascorbic acid. North American, European, and other food, cosmetics, and pharmaceutical companies buy our amphipathic antioxidant. Five advanced HPLC testing equipment maintain batch consistency.

Aside from being very soluble in oils and ethanol, each batch undergoes rigorous quality control. Its chemical formula is C22H38O7.

Ascorbyl Palmitate Powder - Premium Grade Antioxidant from Shaanxi Nuoyuan Biotech

What Is Ascorbyl Palmitate Powder?

The compound is a lipophilic byproduct of vitamin C esterification with palmitic acid. You may add this fat-soluble form of ascorbic acid to systems that don't include water since it doesn't dissolve in oils as fast as regular ascorbic acid.

By addressing critical issues with the formulation, the white to off-white powder (CAS 137-66-6) is achieved. Vitamin C's bioactivity is maintained and PUFA-rich products' lipid peroxidation is inhibited. Around 107–117°C is when it melts. It might undergo processing at high temperatures, rendering regular vitamin C ineffective.

Manufacturers of lipid-rich vitamins, anhydrous cosmetics, and oil-based serums use it as a substrate. Its capacity to penetrate cell membranes not only protects oxygen-sensitive molecules from oxidation, but also aids collagen formation.

Manufacturing Process Excellence

Our production facility employs pharmaceutical-grade esterification under controlled conditions. The four-stage process ensures consistent quality:

Stage	Description	Technical Control
1. Esterification	Catalysis of the interaction between ascorbic acid and palmitic acid	Temperature-controlled enzymatic process
2. Purification	Removal of unreacted materials and byproducts	Multi-stage recrystallization
3. Drying	Moisture elimination under vacuum conditions	Vacuum oven at controlled temperature
4. Milling	Particle size standardization	Precision grinding to specified mesh

We have 5 HPLC systems in-house, checking every step and confirming purity before packing. This vertical integration avoids third-party delays while still adhering to pharmaceutical requirements.

Core Applications in Industries

Formulations for Cosmetics

Your oil-based serums and anti-aging creams need a stable form of vitamin C that won’t oxidise. This chemical provides antioxidant protection and brightens hyperpigmentation without the discomfort of pure ascorbic acid.

Food Preservation

Extend the time items with polyunsaturated fats stay fresh.It helps oils, nuts, and fortified foods stay from going bad, and keeps them safe for labeling as GRAS.

Pharmaceutical Uses

For fat soluble vitamin complexes or topical medicines this derivative also has better skin penetration and prolonged collagen maintenance.

Nutraceutical Supplement

Improve the bioavailability of liposomal vitamin C products by developing them. Lipophilicity safeguards the stomach mucosa and enhances digestion absorption.

FAQ

Q: Why is your Ascorbyl Palmitate more stable than ordinary vitamin C?

A: In lipid settings, where water-soluble forms degrade in hours due to oxidation, palmitate esterification gives fat solubility.

Q: Is private labelling or bespoke specs an option?

A: Yeah. We provide unique purity levels, particle size, and customised packaging as part of our OEM/ODM capabilities, designed to meet your market demands.

Q: What is your minimum order quantity?

A: We can provide samples of 100g for testing. Commercial orders from 25kg with no maximum restriction.

Q: How long is the lead time from order confirmation to shipment?

A: Stock products ship within 2-3 business days. Depending on the specifics, a bespoke formulation might take anywhere from ten to fifteen days to complete.

Q: Do you supply regulatory support documents?

A: With each shipment COA, MSDS, allergy declarations and other related certifications are available. Further information is available on request.

Q: Do you provide technical help during formulation development?

A: We can give guidance on solubility, optimum consumption rates and compatibility with additional substances as you go through your development process.
