Octaethyleneglycol monododecyl ether

Octaethyleneglycol monododecyl ether (CAS 3055-98-9), also known commercially as Akypo Rox RLM22, is a nonionic ethoxylated alcohol surfactant with a C12 hydrophobic tail and an eight-unit ethylene oxide chain. It functions as an emulsifier, wetting agent, and dispersant across a range of industrial and personal care applications. In personal care formulations, it stabilizes emulsions and improves spreadability in creams and lotions.

Textile and paper processing operations use it to enhance substrate wetting and dye penetration, improving uniformity across treatment baths. Water treatment and industrial cleaning formulations rely on its degreasing performance. The chemical is effective at removing oils and particulates from surfaces and process streams. In printing and packaging, it supports ink dispersion and surface modification to improve adhesion and print quality.

Octaethyleneglycol monododecyl ether is typically supplied as a liquid or low-viscosity paste, depending on temperature and concentration. Technical-grade material is the standard commercial offering for most users. High-purity grades are available for personal care and specialty formulation use. It is commonly available in drum and IBC quantities suited to industrial procurement volumes and large scale manufacturing needs.
