Description

1-Octadecanaminium, N,n-Bis(2-Hydroxyethyl)-n-Methyl-, Bromide is a quaternary ammonium salt surfactant characterized by its long alkyl chain and hydroxyethyl functional groups. This structure provides excellent emulsifying, antistatic, and conditioning properties, making it a valuable ingredient in formulations requiring cationic activity and water solubility. It is primarily utilized by manufacturers in the personal care, textile, and industrial cleaning sectors for its ability to modify surface interactions and enhance product performance.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair by neutralizing static charge.
• Fabric Softeners: Imparts a soft, fluffy hand feel to textiles and reduces static cling in dryer sheets and liquid softener formulations.
• Personal Care Emulsions: Serves as an emulsifier and conditioning agent in skin creams, lotions, and other leave-on or rinse-off products.
• Industrial & Institutional (I&I) Cleaners: Used in specialty cleaning formulations for its surfactant and antistatic properties on hard surfaces.
• Antistatic Agents: Applied in plastics, synthetic fibers, and electronics manufacturing to dissipate static electricity.
• Corrosion Inhibition: Can function as a component in corrosion inhibitor packages for industrial water systems or metal processing.
