Description

2-Hydroxyoctadecanoic Acid is a high-purity, long-chain hydroxy fatty acid that serves as a versatile intermediate and functional additive. Its unique amphiphilic structure, featuring both a carboxylic acid group and a hydroxyl group on a C18 backbone, provides valuable properties for synthesis and formulation. This compound is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking to develop surfactants, emulsifiers, or bioactive compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, lipid-based drug delivery systems, and bioactive molecules.
• Cosmetic & Personal Care Ingredients: Acts as a key component in emulsifiers, opacifiers, and viscosity modifiers for creams, lotions, and ointments.
• Specialty Surfactants & Emulsifiers: Serves as a raw material for producing non-ionic and anionic surfactants with specific hydrophilic-lipophilic balance (HLB) values.
• Lubricant & Metalworking Fluid Additives: Utilized as a friction modifier or corrosion inhibitor due to its polar head group and long alkyl chain.
• Polymer Modification: Employed as a monomer or cross-linking agent in the production of polyesters, alkyd resins, and other specialty polymers.
• Research & Development: Serves as a standard or building block in organic synthesis and biochemical research.
