Description

Didodecyl Dimethyl Ammonium Chloride is a high-purity quaternary ammonium compound (QAC) valued for its potent antimicrobial and surfactant properties. This versatile chemical is essential for formulating effective disinfectants, sanitizers, and fabric softeners across multiple industries. It is a critical raw material for manufacturers in the hygiene, personal care, textile, and industrial water treatment sectors seeking reliable, high-performance cationic surfactants.

Application

• Disinfectant & Sanitizer Formulations: A key active ingredient in hospital-grade disinfectants, surface cleaners, and food processing sanitizers due to its broad-spectrum efficacy against bacteria, fungi, and viruses.
• Fabric Softeners & Conditioners: Imparts a soft, antistatic finish to textiles and is widely used in household and industrial fabric care products.
• Industrial Biocides: Used in cooling water systems, paper mills, and oilfield applications to control microbial growth and prevent biofouling.
• Personal Care Products: Functions as a conditioning agent and preservative in hair conditioners, skin creams, and other cosmetic formulations.
• Agricultural Adjuvants: Serves as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adherence.
• Phase Transfer Catalyst: Facilitates reactions between chemicals in different phases in specialty organic synthesis.

Quality Control

Our Didodecyl Dimethyl Ammonium Chloride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and compliance.

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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
