Description

16-(Trimethylsiloxy)Hexadecanoic Acid Methyl Ester is a high-purity organosilicon derivative of a long-chain fatty acid, valued for its unique combination of hydrophobic and reactive functional groups. This compound serves as a versatile intermediate for introducing lipophilic siloxane moieties into target molecules, enhancing properties like water repellency, surface modification, and compatibility. It is primarily sought by R&D chemists and process engineers in the specialty chemicals, personal care, and advanced materials sectors for synthesizing novel surfactants, polymers, and surface-active agents.

Application

• Intermediate for Silicone-Modified Surfactants: Key building block for synthesizing novel organosilicone surfactants and emulsifiers used in high-performance personal care formulations and industrial cleaners.
• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to textiles, paper, and various inorganic substrates like glass or metal oxides.
• Polymer & Resin Additive: Used as a reactive modifier or internal lubricant in specialty polymer systems to improve processing, release properties, and surface characteristics.
• Lubricant & Release Agent Synthesis: Serves as a precursor for creating specialized lubricants and mold release agents with enhanced thermal stability and low surface energy.
• Cosmetic & Personal Care Ingredients: Employed in the synthesis of conditioning agents, emollients, and film-formers for hair care and skincare products.
• Adhesion Promoter: Functions as a coupling agent to improve adhesion between organic polymers and inorganic surfaces in coatings and composite materials.

Quality Control

Our production of 16-(Trimethylsiloxy)Hexadecanoic Acid Methyl Ester adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from strong acids and bases.
