Description

Polypropylene Glycol Monobutyl Ether Stearate is a non-ionic surfactant and emulsifier derived from polypropylene glycol, butanol, and stearic acid. This versatile chemical is valued for its ability to modify surface tension, stabilize formulations, and act as a coupling agent between polar and non-polar components. It is essential for manufacturers in the personal care, coatings, and industrial lubricant sectors seeking reliable performance additives.

Application

• Personal Care & Cosmetics: Acts as an emulsifier and opacifier in creams, lotions, and hair conditioners, providing a smooth texture and stable emulsion.
• Coatings & Inks: Serves as a dispersing agent and flow control additive in solvent-based coatings, improving pigment wetting and film formation.
• Industrial Lubricants & Metalworking Fluids: Functions as a lubricity additive and emulsifier, enhancing the performance and stability of synthetic and semi-synthetic fluids.
• Plastic & Rubber Processing: Used as an internal and external release agent and lubricant to aid in mold release and improve processing.
• Textile Auxiliaries: Employed as a softening agent and lubricant in fiber processing and finishing to reduce friction and improve handle.
• Adhesives & Sealants: Acts as a plasticizer and compatibility agent, modifying the rheology and improving the adhesion properties of various formulations.

Quality Control

Our Polypropylene Glycol Monobutyl Ether Stearate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as acid value, saponification value, and hydroxyl value 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, well-ventilated area away from strong alkalis and organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent moisture absorption and contamination.
