Description

22-Hydroxydocosanoic Acid (ω-Hydroxybehenic Acid) is a high-purity, long-chain hydroxy fatty acid characterized by a terminal hydroxyl group. This unique bifunctional structure makes it a valuable intermediate for synthesizing specialized polymers, surfactants, and lubricants where both carboxylic acid and alcohol reactivity are required. It is particularly sought after by manufacturers in the personal care, cosmetics, and specialty chemical industries for producing high-performance esters and emollients.

Application

• Polymer & Resin Synthesis: Key monomer for producing polyesters and polyamides with specific flexibility and hydrophobicity.
• Cosmetic & Personal Care Ingredients: Used to synthesize emollient esters, waxes, and conditioning agents for creams, lotions, and hair care products.
• Lubricant & Grease Additives: Serves as a building block for high-performance synthetic esters used in industrial and automotive lubricants.
• Surfactant & Detergent Intermediate: Utilized in the production of non-ionic and anionic surfactants for specialized cleaning formulations.
• Pharmaceutical Intermediates: Potential use in the synthesis of prodrugs or controlled-release drug delivery systems.
• Research & Development: A valuable standard and reagent in lipid chemistry and material science research.

Quality Control

Our 22-Hydroxydocosanoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and titration methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality.
