Description

Hexadecyldimethylammonium Acetate is a quaternary ammonium salt (quat) with a long alkyl chain, valued for its potent cationic surfactant and antimicrobial properties. Its primary commercial value lies in its ability to function as a phase-transfer catalyst, emulsifier, and biocide across diverse industrial formulations. This compound is essential for manufacturers in the personal care, agrochemical, textile, and water treatment industries seeking effective and versatile cationic agents.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, crucial in organic synthesis for pharmaceuticals and specialty chemicals.
• Antimicrobial Agent: Used as a preservative and disinfectant in cosmetic formulations, industrial biocides, and sanitizing products.
• Emulsifier & Softener: Imparts conditioning and softening properties in hair care products, fabric softeners, and textile auxiliaries.
• Agrochemical Adjuvant: Enhances the efficacy and adhesion of pesticides and herbicides on plant surfaces.
• Water Treatment: Acts as an algicide and flocculant aid in industrial cooling and process water systems.
• Analytical Chemistry: Employed in ion-pair chromatography for the separation of ionic species.
• Nanomaterial Synthesis: Serves as a cationic surfactant template in the preparation of mesoporous silica and other structured materials.

Quality Control

Our Hexadecyldimethylammonium Acetate is manufactured under a strict quality management system. Each 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 characteristics is provided with every shipment to guarantee consistency and traceability for your critical applications.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
