Description

(Carboxylatomethyl)Dimethyl(Octadecyl)Ammonium is a quaternary ammonium compound with a long alkyl chain and a carboxylatomethyl functional group. This unique structure provides it with excellent surfactant properties, combining cationic activity with potential anionic character, making it a versatile intermediate for specialty chemical synthesis. It is primarily sought after by manufacturers in the personal care, textile, and industrial cleaning sectors for formulating conditioners, softeners, and biocidal agents. Its functionality is critical for developing products that require both emulsification and substantive properties on various substrates.

Application

• Hair Conditioner & Cosmetic Ingredient: Acts as a substantive conditioning agent, providing softness and manageability to hair.
• Fabric Softener & Textile Auxiliary: Imparts a soft hand feel and antistatic properties to textiles and fabrics.
• Industrial & Institutional (I&I) Cleaners: Serves as a surfactant and emulsifier in hard-surface cleaning formulations.
• Biocide & Disinfectant Intermediate: Used in the synthesis of quaternary ammonium compounds (QACs) with enhanced biocidal activity.
• Paper Softening Agent: Employed in the paper manufacturing process to improve sheet softness.
• Antistatic Agent for Plastics: Provides internal or external antistatic properties to polymer films and moldings.
• Emulsifier for Specialty Polymers: Functions as an emulsifying agent in polymerization processes for latexes and resins.
• Oilfield Chemical Additive: Used as a corrosion inhibitor or surfactant in drilling and production fluids.

Quality Control

Our (Carboxylatomethyl)Dimethyl(Octadecyl)Ammonium is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, moisture content, and residual solvents. While produced to meet general industrial standards, specifications can be aligned with customer-specific requirements for 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 after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
