Description

5-Hexadecylsalicylic Acid is a long-chain alkyl derivative of salicylic acid, offering unique amphiphilic properties due to its aromatic carboxylic acid head and long aliphatic tail. This compound is valued for its role as a versatile intermediate and functional additive, particularly in the synthesis of specialized surfactants and emulsifiers. It is primarily utilized by manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking to modify surface properties or create novel lipid-based compounds.

Application

• Surfactant & Emulsifier Intermediate: A key building block for synthesizing non-ionic and anionic surfactants used in detergents, cosmetics, and industrial cleaners.
• Personal Care Formulations: Acts as a co-emulsifier and stabilizer in creams, lotions, and ointments, leveraging its lipid-like structure for enhanced skin compatibility.
• Pharmaceutical Synthesis: Serves as a precursor or modifying agent in the development of prodrugs and lipophilic drug derivatives to improve bioavailability.
• Polymer Additive: Used as an internal or external lubricant and processing aid in plastics and polymer production.
• Corrosion Inhibitor Formulation: Incorporated into protective coatings and additives for metals, where its film-forming characteristics provide a barrier.
• Research & Development: Employed in academic and industrial R&D for studying self-assembly, micelle formation, and as a model compound in organic synthesis.

Quality Control

Our 5-Hexadecylsalicylic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
