Description

Quaternary Ammonium Compounds, C12-18-Alkyl(Hydroxyethyl)Dimethyl, Chlorides are a versatile class of cationic surfactants widely valued for their potent antimicrobial, antistatic, and conditioning properties. Their molecular structure, featuring a long alkyl chain and a hydroxyethyl group, provides excellent surface activity, compatibility, and mildness. This product is essential for manufacturers in the personal care, textile, and industrial cleaning sectors seeking high-performance, multifunctional ingredients.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic conditioning agent, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners: Imparts a soft, fluffy hand feel to textiles and reduces static cling in laundry applications.
• Disinfectant & Sanitizer Formulations: Serves as a key active ingredient in quaternary ammonium compound (QAC or Quat) based disinfectants for hard surface cleaning in institutional and industrial settings.
• Industrial Biocides: Used in water treatment, oilfield, and pulp/paper industries for microbial control due to its broad-spectrum efficacy.
• Antistatic Agents: Applied in plastics, textiles, and electronics manufacturing to dissipate static electricity.
• Emulsification & Phase Transfer Catalysis: Facilitates the formation and stability of emulsions and can act as a catalyst in certain organic synthesis reactions.

Quality Control

Our Quaternary Ammonium Compounds are manufactured under a strict quality management system. Each batch is tested to ensure consistent performance and meets relevant industry specifications. Certificates of Analysis (COA) documenting key parameters such as active matter content, pH, and color are available upon request. We can support compliance needs for various applications, including those requiring cosmetic-grade or industrial-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure containers are properly sealed after use to prevent absorption of atmospheric moisture.
