Polyethylene glycol monobutyl ether

Polyethylene glycol monobutyl ether (CAS 9004-77-7), commercially available as DCP 208 and Adeka Carpol M2, is a nonionic surfactant and solvent used across industrial and personal care manufacturing.

Its butyl-capped polyethylene glycol structure delivers controlled hydrophilic-lipophilic balance, making it effective for emulsification, dispersion, and surface-active cleaning applications.

In textile and leather processing, it functions as a leveling and dispersing agent, improving dye uptake uniformity and finish consistency across various substrates during the manufacturing process.

Metalworking and industrial cleaning formulators incorporate it into water-based cutting fluids and degreasers, where it solubilizes oils and facilitates rinsing without the need for aggressive solvents.

Personal care manufacturers use it as a solvent and emulsifier in rinse-off formulations, helping to disperse actives and condition processing behavior for high-quality consumer products.

In paper manufacturing, it supports surface sizing and coating formulations by improving pigment dispersion and film-forming agent compatibility, ensuring a smooth and consistent finish.

Polyethylene glycol monobutyl ether is supplied as a clear to slightly hazy liquid. It is available in technical and industrial grades, with molecular weight variants determining HLB value.

Buyers should specify chain length or equivalent grade designation when sourcing. Bulk liquid supply in drums and IBCs is standard for industrial procurement and large-scale chemical distribution.
