Description

(2-Hydroxyethyl)(2-Hydroxyhexadecyl)Dimethylammonium Chloride is a quaternary ammonium compound (quat) valued for its unique combination of cationic surfactant properties and hydroxyl functionality. This structure makes it particularly effective as an emulsifier, softener, and antistatic agent in demanding formulations. It is essential for manufacturers in the personal care, textile, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Textile Auxiliaries: Imparts a soft, smooth hand feel to fabrics and provides durable antistatic properties.
• Skin Care Emulsions: Serves as an effective emulsifier and conditioning agent in creams and lotions, improving skin feel and formulation stability.
• Industrial Biocides & Sanitizers: Utilized as an active ingredient or synergistic component in disinfectant formulations for its antimicrobial efficacy.
• Paper Coatings & Sizing: Functions as a softener and processing aid to improve the quality and tactile properties of paper products.
• Antistatic Agents for Plastics: Incorporated into polymer coatings and films to reduce static charge accumulation.
