Description

Methyltris[2-[(1-oxooctadecyl)oxy]ethyl]ammonium methyl sulphate is a quaternary ammonium compound with a complex, multi-tailed structure, functioning as a cationic surfactant and fabric softener agent. Its primary commercial value lies in its potent conditioning and antistatic properties, which are essential for enhancing the feel and performance of textiles and personal care formulations. This chemical is a critical raw material for manufacturers in the fabric care, hair conditioning, and industrial surfactant sectors who require reliable, high-purity ingredients for their production processes.

Application

• Fabric Softeners and Conditioners: Primary active ingredient in liquid and dryer sheet formulations to impart softness, reduce static cling, and improve fabric manageability.
• Hair Care Products: Key conditioning agent in shampoos, conditioners, and hair masks to provide detangling, smoothness, and shine.
• Industrial Surfactants: Used as a cationic emulsifier, dispersant, or antistatic agent in various industrial processes and specialty chemical blends.
• Textile Auxiliaries: Employed in textile finishing to provide a soft hand feel and antistatic properties to synthetic and natural fibers.
• Personal Care Formulations: Incorporated into skin creams and lotions for its emollient and conditioning effects.
• Agricultural Adjuvants: Can be used as a component in pesticide or herbicide formulations to improve adhesion and spreading on plant surfaces.

Quality Control

Our Methyltris[2-[(1-oxooctadecyl)oxy]ethyl]ammonium methyl sulphate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
