Description

Oxirane, Methyl-, Polymer With Oxirane, 2-(2-Methoxyethoxy)Ethyl Ether is a specialized polyether polymer, commonly known as a poly(ethylene glycol) methyl ether-block-poly(propylene glycol)-block-poly(ethylene glycol) methyl ether triblock copolymer. This compound is valued for its unique surfactant and rheology-modifying properties, making it an essential functional additive in advanced formulations. It is primarily sought by manufacturers in the personal care, pharmaceutical, and industrial sectors for its ability to stabilize emulsions, modify viscosity, and enhance solubility.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, and stabilizer in topical creams, ointments, and transdermal drug delivery systems.
• Personal Care Formulations: Acts as a non-ionic surfactant and viscosity modifier in shampoos, lotions, and cosmetic products for improved texture and stability.
• Polymer Processing Aid: Functions as a compatibilizer and processing aid in the production of polyurethane foams and other specialty polymers.
• Laboratory Reagent: Utilized in biochemical and chemical research as a phase transfer catalyst or a component in buffer solutions.
