Description

Peg 200 Monoisostearate is a non-ionic surfactant and emulsifier derived from polyethylene glycol and isostearic acid. This versatile chemical is valued for its excellent solubilizing, dispersing, and conditioning properties in a wide range of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and industrial lubricant sectors seeking stable, high-performance emulsions.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, and ointments, providing a smooth texture and stable oil-in-water emulsions.
• Pharmaceutical Topicals: Used as an excipient in topical drug delivery systems to enhance the solubility and skin penetration of active pharmaceutical ingredients.
• Industrial Lubricants & Metalworking Fluids: Serves as an emulsifier and lubricity agent, improving the stability and performance of water-based lubricants and coolants.
• Textile & Fiber Processing: Functions as a softener, lubricant, and antistatic agent in fiber spin finishes and fabric conditioning treatments.
• Agricultural Adjuvants: Employed as a surfactant and emulsifier in pesticide and herbicide formulations to improve spreading and adherence on plant surfaces.
• Plastic & Polymer Additives: Used as an internal or external lubricant and anti-static agent in polymer processing to improve flow and mold release.

Quality Control

Our Peg 200 Monoisostearate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as acid value, saponification value, hydroxyl value, and moisture content 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
