octaethylene glycol monooctadecyl ether

Description:
Octaethylene glycol monooctadecyl ether, with the CAS number 13149-87-6, is a nonionic surfactant characterized by its long hydrophobic alkyl chain and a hydrophilic polyethylene glycol (PEG) segment. This compound typically features a structure that includes an octadecyl group (derived from stearyl alcohol) attached to an octaethylene glycol moiety, which consists of eight ethylene glycol units. As a surfactant, it exhibits excellent emulsifying, wetting, and dispersing properties, making it useful in various applications, including cosmetics, pharmaceuticals, and industrial formulations. Its nonionic nature allows it to be compatible with a wide range of other surfactants and formulations, enhancing its versatility. Additionally, octaethylene glycol monooctadecyl ether is known for its low toxicity and good biodegradability, contributing to its appeal in environmentally friendly formulations. The compound is typically a viscous liquid or waxy solid at room temperature, and its solubility in water is limited due to the hydrophobic alkyl chain, although it can be solubilized in organic solvents.
