Cas no 2136-71-2 (2-Hexadecyloxyethanol)

2-Hexadecyloxyethanol is a nonionic surfactant characterized by its amphiphilic structure, combining a hydrophilic ethoxylate group with a hydrophobic hexadecyl (C16) chain. This compound exhibits excellent emulsifying, wetting, and dispersing properties, making it suitable for applications in industrial formulations, personal care products, and agrochemicals. Its long alkyl chain enhances stability in hydrophobic matrices, while the ethoxylate moiety ensures moderate water solubility. The surfactant demonstrates compatibility with a wide range of polar and nonpolar substances, offering balanced surface activity. Its thermal and chemical stability further supports its use in high-temperature or chemically aggressive environments. The product is typically supplied as a clear to pale-yellow liquid or low-melting solid, depending on purity and storage conditions.
