Description

Hexadecylsuccinic Acid is a high-purity, long-chain aliphatic dicarboxylic acid derivative valued for its hydrophobic character and versatile reactivity. This compound serves as a critical intermediate and functional additive, enabling precise material modification and performance enhancement in advanced formulations. It is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to improve product durability, compatibility, and surface activity.

Application

• Polymer Additive & Modifier: Acts as a chain extender, corrosion inhibitor, or internal lubricant in engineering plastics, coatings, and adhesives.
• Lubricant & Grease Formulation: Used as a thickening agent and performance additive to enhance viscosity, thermal stability, and anti-wear properties.
• Metalworking Fluids: Functions as a corrosion inhibitor and emulsifier in synthetic and semi-synthetic cutting and grinding fluids.
• Surfactant & Emulsifier Synthesis: Serves as a key hydrophobic intermediate for producing specialty surfactants with low foaming and good wetting characteristics.
• Pharmaceutical & Cosmetic Intermediates: Utilized in the synthesis of esters and other derivatives for controlled-release formulations and emollients.
• Textile & Leather Auxiliaries: Employed as a softening agent and water-repellent finish to improve fabric hand-feel and durability.

Quality Control

Our Hexadecylsuccinic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical constants is provided with each shipment to guarantee traceability and compliance with your quality requirements.

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 and handling properties.
