Description

Polyoxyethylene Stearate is a non-ionic surfactant and emulsifier derived from stearic acid and ethylene oxide. This versatile compound is valued for its ability to stabilize emulsions, modify viscosity, and act as a dispersing agent in a wide range of industrial formulations. It is a critical ingredient for manufacturers in the cosmetics, pharmaceuticals, food processing, and agrochemical industries seeking reliable and effective surface-active properties.

Application

• Primary emulsifier and stabilizer in cosmetic and personal care products such as creams, lotions, and ointments.
• Used as a solubilizer and co-emulsifier in pharmaceutical preparations for topical and oral delivery.
• Food-grade applications as an emulsifier and dispersant in baked goods, dairy products, and edible oils.
• Key component in textile processing as a lubricant, softener, and antistatic agent for fibers.
• Emulsifier and adjuvant in pesticide and agrochemical formulations to enhance spray coverage and efficacy.
• Industrial applications in paints, coatings, and polishes as a viscosity modifier and dispersing aid.
• Plastic and polymer processing as an internal and external lubricant and anti-static agent.

Quality Control

Our Polyoxyethylene Stearate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for critical parameters such as saponification value, hydroxyl value, acid value, and melting point. We provide comprehensive Certificates of Analysis (COA) with every shipment and can support compliance with relevant standards for food (FCC), pharmaceutical (USP/NF), and industrial applications.

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); ensure containers are sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
