Description

[2-[2-Hydroxy-3-[(1-Oxooctadecyl)Oxy]Propoxy]-2-Oxoethyl]Dimethyloctadecylammonium Chloride is a high-purity quaternary ammonium compound (quat) with a unique esterquat structure, offering a combination of cationic and ester functionalities. This matters for formulators seeking advanced conditioning, emulsification, and antistatic properties in products requiring both substantive deposition and environmental compatibility. It is primarily needed by manufacturers in the personal care, textile, and industrial surfactant sectors for creating premium rinse-off conditioners, fabric softeners, and specialty emulsifiers.

Application

• Hair Care Formulations: As a primary cationic surfactant in premium hair conditioners, creams, and masks, providing excellent detangling, softness, and manageability.
• Fabric Softeners & Conditioners: A key active ingredient in liquid and concentrated fabric softeners, delivering superior softness, static control, and fragrance retention on textiles.
• Skin Care & Cosmetics: Used in rinse-off skin cleansers and shaving products for its mildness and ability to impart a smooth, conditioned feel.
• Industrial Surfactants & Emulsifiers: Functions as a specialty emulsifier and antistatic agent in industrial polishes, coatings, and lubricant formulations.
• Biocide & Disinfectant Synergist: Can enhance the efficacy of antimicrobial formulations due to its cationic nature and surface-active properties.
