Description

Bis(2-Hydroxypropyl)Methyl(Octadecyl)Ammonium Methyl Sulphate is a quaternary ammonium compound valued for its cationic surfactant properties and excellent compatibility with various formulations. This chemical is essential for creating stable, effective products that require emulsification, antistatic, or conditioning performance. It is primarily needed by manufacturers in the personal care, textile processing, and industrial cleaning sectors seeking reliable, high-performance ingredients.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Textile Auxiliaries: Imparts a soft hand feel and reduces static cling on natural and synthetic fibers.
• Industrial & Institutional (I&I) Cleaners: Used as an emulsifier and antistatic agent in hard surface cleaners and floor polishes.
• Personal Care Emulsions: Serves as an emulsifying agent in skin creams and lotions, helping to stabilize oil-in-water systems.
• Antistatic Agents for Plastics: Incorporated into polymer coatings or treatments to dissipate static electricity.
• Agricultural Adjuvants: Can be used as a component in pesticide or herbicide formulations to improve spreading and adhesion.

Quality Control

Our Bis(2-Hydroxypropyl)Methyl(Octadecyl)Ammonium Methyl Sulphate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, moisture content, and other critical parameters is available upon request to 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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
