Description

Trimethyloleylammonium Chloride is a quaternary ammonium salt (quat) featuring a long-chain oleyl group, making it a versatile cationic surfactant and conditioning agent. Its structure provides excellent substantivity to various surfaces, particularly those with a negative charge, which is critical for performance in industrial and personal care formulations. This compound is essential for manufacturers in the personal care, textile, and oilfield chemical industries seeking effective antistatic, emulsifying, and softening properties.

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 care products.
• Industrial Antistatic Agents: Used in plastics, synthetic fibers, and coatings to dissipate static electricity and prevent dust attraction.
• Emulsifier for Oily Phases: Facilitates the formation and stabilization of oil-in-water (O/W) emulsions in cosmetic and industrial formulations.
• Oilfield Chemicals: Serves as a clay stabilizer and surfactant in drilling and completion fluids to control clay swelling and improve fluid performance.
• Biocide & Disinfectant Formulations: Used as a component in synergistic blends for its surfactant and antimicrobial properties.
