Ethylene oxide-propylene oxide triblock copolymer

Description:
Ethylene oxide-propylene oxide triblock copolymer, identified by CAS number 691397-13-4, is a type of non-ionic surfactant and polymer that exhibits unique properties due to its block copolymer structure. This substance consists of alternating blocks of ethylene oxide (EO) and propylene oxide (PO), which contribute to its amphiphilic nature, allowing it to interact with both hydrophilic and hydrophobic environments. The EO blocks typically enhance water solubility, while the PO blocks provide hydrophobic characteristics, making this copolymer useful in various applications, including as a surfactant, emulsifier, and stabilizer in formulations. It is known for its low toxicity and biocompatibility, which makes it suitable for use in pharmaceuticals, personal care products, and industrial applications. Additionally, the triblock structure imparts thermal stability and mechanical strength, enhancing its performance in diverse conditions. Overall, this copolymer is valued for its versatility and effectiveness in modifying surface properties and stabilizing emulsions.
