Ascorbyl Palmitate Specifications: Quality for Food & Pharma Needs

Ascorbyl Palmitate, a fat-soluble ester of Vitamin C, is a critical ingredient sought after for its antioxidant and nutritional properties, particularly within the food, pharmaceutical, and cosmetic sectors. For businesses aiming to buy Ascorbyl Palmitate, understanding its precise specifications is paramount to ensuring it meets the rigorous demands of their applications. Manufacturers in China play a key role in supplying this compound, often adhering to stringent international quality benchmarks.

The chemical identity of Ascorbyl Palmitate is confirmed by its CAS number, 137-66-6, and its molecular formula, C22H38O7. Typically, it presents as a white to yellowish-white powder, a critical visual specification for quality control. The purity is often defined by its assay, which typically must be a minimum of 98% on a dried basis, as determined by titrimetric methods. This high level of purity is essential for applications where consistency and performance are non-negotiable, such as in pharmaceutical formulations or high-grade food additives.

Compliance with international pharmacopeia and food codex standards is a key differentiator for suppliers. Ascorbyl Palmitate that meets USP (United States Pharmacopeia), BP (British Pharmacopoeia), EP (European Pharmacopoeia), and FCC (Food Chemicals Codex) standards signifies a commitment to quality and safety. These standards dictate specific parameters for:

  • Appearance: White to yellowish-white powder.
  • Assay: Minimum 98% purity.
  • Loss on Drying: A maximum limit, typically around 2%, to ensure minimal moisture content.
  • Residue on Ignition: A low maximum limit, usually 0.1%, indicating minimal inorganic impurities.
  • Optical Specific Rotation: A defined range (e.g., +21° to +24°) measured under specific conditions, confirming the correct stereoisomer.
  • Heavy Metals/Lead Content: Strict limits, such as a maximum of 2 ppm for lead, to ensure safety.

These specifications are not merely technical details; they are critical indicators of product quality and suitability for sensitive applications. For businesses sourcing from China, working with Ascorbyl Palmitate suppliers who readily provide detailed Certificates of Analysis (COA) that confirm adherence to these specifications is crucial. This documentation provides assurance that the purchased ingredient will perform as expected and meet regulatory requirements.

Beyond the core chemical purity, specifications also extend to other aspects like non-GMO status, Halal, and Kosher certifications, which are increasingly important for global market access. Understanding these requirements allows buyers to select suppliers who align with their product development and market strategies. For those seeking to purchase Ascorbyl Palmitate, the availability of comprehensive product specifications and supporting documentation from their chosen manufacturer or supplier is a key factor in establishing a reliable B2B relationship.
