Description

Polyethylene Glycol Stearate is a versatile non-ionic surfactant and emulsifier derived from the esterification of stearic acid with polyethylene glycol. This compound is valued for its ability to stabilize emulsions, modify viscosity, and provide lubricating and softening properties across diverse industrial formulations. It is a critical ingredient for manufacturers in the cosmetics, pharmaceuticals, and food processing industries seeking reliable, multifunctional excipients and processing aids.

Application

• Cosmetics & Personal Care: Acts as a primary emulsifier, opacifier, and pearlizing agent in creams, lotions, shampoos, and conditioners.
• Pharmaceuticals: Used as a non-ionic emulsifier, solubilizer, and ointment base in topical creams, ointments, and suppositories.
• Food Industry: Functions as an emulsifier, dispersing agent, and texturizer in various food products, often where a stable oil-in-water emulsion is required.
• Industrial Applications: Serves as a lubricant, anti-static agent, and mold release agent in plastics, textiles, and metalworking fluids.
• Agrochemicals: Employed as an adjuvant in pesticide and herbicide formulations to enhance spreading and wetting on plant surfaces.

Quality Control

Our Polyethylene Glycol Stearate is manufactured under a strict quality management system. Each batch is tested to ensure it meets defined specifications for critical parameters such as acid value, saponification value, hydroxyl value, and melting point. Certificates of Analysis (COA) are provided with every shipment. We can supply grades suitable for industrial, cosmetic, and food applications, with compliance to relevant standards such as FCC (Food Chemicals Codex) and CTFA (Cosmetic Ingredient Review) guidelines upon request.

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 material is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket). Keep away from strong oxidizing agents.
