Description

Ethoxypolyethylene Glycol is a versatile non-ionic surfactant and polymer intermediate, widely recognized for its excellent solubility, low toxicity, and tunable properties. This compound is crucial for formulators seeking to modify surface tension, enhance stability, or act as a solubilizing agent in complex mixtures. It is particularly valuable for industries such as pharmaceuticals, personal care, agrochemicals, and industrial manufacturing where reliable performance and material consistency are paramount.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, and coating agent in drug formulations and controlled-release systems.
• Personal Care & Cosmetics: Functions as a surfactant, emulsifier, and viscosity modifier in creams, lotions, and shampoos.
• Agrochemical Adjuvant: Enhances the spreading, penetration, and efficacy of pesticides and herbicides.
• Industrial Surfactant: Employed in textile processing, metalworking fluids, and as a dispersant in various chemical processes.
• Polymer Modification: Serves as a precursor or macromonomer for synthesizing specialized polyethers and block copolymers.
• Laboratory Reagent: Utilized in biochemical research and as a phase-transfer catalyst in organic synthesis.

Quality Control

Our Ethoxypolyethylene Glycol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as hydroxyl value, average molecular weight, and water content are available upon request. We adhere to relevant cGMP and ISO 9001 standards where applicable to guarantee supply reliability and product consistency for our global B2B partners.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
