Description

(2-Hydroxyethyl)Methylbis[2-[(1-Oxooctadecyl)Oxy]Ethyl]Ammonium Hydrogen Sulphate is a quaternary ammonium compound with a stearate ester structure, functioning as a cationic surfactant and fabric softener active. It matters for its excellent softening, antistatic, and emulsifying properties, making it a key ingredient in high-performance formulations. This product is primarily needed by manufacturers in the textile, personal care, and household chemical industries for producing rinse-cycle fabric softeners, hair conditioners, and specialty industrial emulsifiers.

Application

• Primary Fabric Softener Active: Key cationic component in liquid and concentrated rinse-cycle fabric softeners for imparting softness and reducing static cling on textiles.
• Hair Care Conditioning Agent: Used in cream rinses and hair conditioners to provide detangling, smoothness, and manageability.
• Industrial Textile Auxiliary: Employed as a softener and antistatic agent in the finishing of synthetic fibers and blends during textile manufacturing.
• Specialty Emulsifier: Acts as a cationic emulsifier for creating stable oil-in-water emulsions in certain cosmetic and industrial applications.
• Paper Softening: Utilized in the paper manufacturing process to improve the hand-feel and softness of tissue and hygiene paper products.
• Leather Processing Aid: Applied in leather treatment to soften hides and improve their quality and texture.

Quality Control

Our (2-Hydroxyethyl)Methylbis[2-[(1-Oxooctadecyl)Oxy]Ethyl]Ammonium Hydrogen Sulphate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets the specifications required for fabric care and cosmetic applications. Certificates of Analysis (COA) documenting key parameters such as active matter content, iodine value, and pH are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality. Keep away from strong oxidizing agents.
