Vitamin B3 Powder

Vitamin B3 Powder of the Highest Quality | USP/EP Grade | cGMP Certified

Shaanxi Hongda Phytochemistry Co., Ltd. is a leading manufacturer of high-purity Vitamin B3 powder (niacin, CAS 59-67-6). Our niacinamide powder uses pharmaceutical-grade 3-methylpyridine, manufactured using modern catalytic oxidation and purification processes. First, the oxidation reaction is strictly controlled, followed by multi-stage crystallization and filtration to achieve a purity of 99.5% - 100.5% (compliant with internationally accepted pharmacopoeia absolute quantification standards). We ensure that every kilogram entering the formulation tank consists of pure active molecules, achieving the theoretical upper limit of its whitening, oil-controlling, and repairing effects through biochemical design.

Key Advantages:

• High Bioavailability: Supplements that are easy to absorb
• Free Niacin Residue: 100 ppm (parts per ten thousand limit; actual measured level in high-end cosmetics is less than 20 ppm), eliminating the "niacin redness reaction" caused by capillary dilation, making the finished serums and creams extremely gentle on sensitive skin.
• Free Pyridine Residue: Not detected (ND, detection limit less than 2 ppm, gas chromatography-mass spectrometry), exhibiting odorless and pure properties, eliminating the need to add large amounts of expensive fragrances to mask industrial odors, perfectly meeting pure cosmetic standards.
• Quality Assurance: A COA for each batch that checks for microorganisms and heavy metals
• Certifications: cGMP, ISO 9001, and USP/EP standards are used all throughout the world to make sure things are done right.
• Uses: cosmetics, fortified foods, cholesterol-lowering drugs, and dietary supplements.

Key Specifications

Core Production Process (Chemical Synthesis)

Reaction:

• 3-Cyanopyridine + Ammonia → Nicotinamide (with a catalyst at high heat and pressure).
• Buyer Focus: Keeping impurities to a minimum, controlling the yield of the reaction, and making sure the raw materials are pure.

Cleaning and crystallizing:

• Filtration or activated carbon gets rid of impurities.
• Controlled cooling made pure nicotinamide crystals.
• Buyer Focus: *Level of purity (>99.5%), crystal structure (which impacts solubility and stability), and consistency.*

Drying and milling:

• Crystals dried to less than 0.5% water.
• Ground to a very specific and even size of powder particles.
• Buyer Focus: controlling moisture (shelf life), making the powder flow, and how well it dissolves.

Quality Assurance (Not up for discussion):

• Testing that is quite strict: identification (HPLC/FTIR), potency (assay), purity/impurities (HPLC), heavy metals, and microbiological.
• Batches may be traced, and they follow GMP.
• Focus on the buyer: following specifications, following rules (USP/EP/FCC), and making sure each batch is the same.

Applications of Vitamin B3 Powder

• Cholesterol Management: Core ingredient in extended-release Niacin tablets.
• Dietary Supplements: Enhances energy metabolism in capsule/tablet formulations.
• Intravenous Nutrition: Meets USP-NF standards for injectable therapies.
• Cosmetic & Skincare: Stabilized Niacinamide for anti-aging serums.
