Overview
Polyethylene Glycol (4) Ether, or PEG-4 Ether, is a versatile non-ionic surfactant derived from the polymerization of ethylene oxide. It is part of the larger family of polyethylene glycol ethers, which are widely used across various industries due to their emulsifying and dispersing properties. PEG-4 Ether is particularly valued for its ability to reduce surface tension between liquids or between a liquid and a solid, making it an essential component in formulations requiring stability and homogeneity. Its applications span from household cleaning products to industrial processes, where its performance and safety profile are highly regarded.
Physical and Chemical Properties
PEG-4 Ether is characterized by its viscous liquid form, typically colorless to pale yellow. It is soluble in both water and most organic solvents, which enhances its versatility in various formulations. The compound's molecular weight is approximately 194.23 g/mol, and it has a density of around 1.09 g/cm³. Its non-ionic nature means it does not ionize in water, making it compatible with a wide range of other chemicals without causing precipitation or instability. The melting and boiling points can vary depending on the specific formulation, but PEG-4 Ether generally remains stable under a broad range of temperatures and pH levels.
Main Applications
PEG-4 Ether is extensively used in the production of detergents and cleaning agents, where it acts as an emulsifier and wetting agent. Its ability to break down oils and greases makes it a key ingredient in both household and industrial cleaners. In the cosmetics industry, PEG-4 Ether is employed in formulations of shampoos, lotions, and creams due to its mildness and emulsifying properties. It helps to stabilize mixtures of oil and water, ensuring a smooth and consistent product texture. Additionally, it finds applications in pharmaceuticals as a solubilizing agent and in textile processing to improve dye penetration and fabric softness.
Safety and Storage
PEG-4 Ether is generally considered safe with low toxicity levels, but proper handling is still essential. Prolonged skin contact should be avoided to prevent potential irritation, and inhalation of vapors or mists should be minimized in industrial settings. For storage, PEG-4 Ether should be kept in a cool, dry place away from direct sunlight and oxidizing agents. Containers should be tightly sealed to prevent moisture absorption and contamination. In case of spills, the area should be cleaned promptly with water and appropriate protective equipment.
B2B Procurement Guide
When sourcing PEG-4 Ether, B2B buyers should prioritize suppliers with a proven track record of reliability and quality assurance. It is crucial to verify the purity and consistency of the product, as variations can impact performance in end-use applications. Buyers should also consider the supplier's compliance with industry standards and regulations, such as REACH or FDA approvals, depending on the intended use. Price negotiations should factor in bulk purchase discounts, but the focus should remain on product quality and supplier credibility.
