Description

Palmitic Acid CAS NO 57-10-3 is a saturated long-chain fatty acid and a fundamental building block in organic chemistry. It serves as a critical raw material and intermediate for a wide range of industrial and consumer product formulations. This versatile compound is essential for manufacturers in the personal care, food, pharmaceutical, and chemical synthesis sectors seeking reliable quality and consistent supply.

Application

• Soap & Detergent Manufacturing: A primary raw material for producing sodium palmitate, a key component in traditional bar soaps, providing hardness and a stable lather.
• Cosmetics & Personal Care: Used as an opacifying agent, emulsifier, and surfactant in creams, lotions, and other skincare products.
• Food Industry (as an additive): Functions as a lubricant, release agent, and texturizer (e.g., in chewing gum base) under food-grade specifications.
• Pharmaceutical Excipient: Employed in tablet and capsule formulations as a binder and coating agent to control drug release.
• Lubricants & Greases: Acts as a precursor for metallic soaps (e.g., lithium, calcium, aluminum palmitates) used as thickeners in lubricating greases.
• Candle Making: Used to harden candles, improving burn time and structural integrity.
• Chemical Synthesis: A vital intermediate for producing esters, amides, alcohols, and other derivatives for plastics, coatings, and surfactants.
• Textile & Leather Processing: Applied as a softening and waterproofing agent in finishing processes.

Quality Control

Our Palmitic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, iodine value, and melting point are available upon request. We can supply grades compliant with various standards, including Food Chemical Codex (FCC) and Kosher, subject to specific customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and strong oxidizing agents. For long-term storage under optimal conditions, a temperature-controlled environment is recommended to prevent discoloration or lump formation.
