What is Polyethylene glycol monobutyl ether?

Polyethylene glycol monobutyl ether (CAS 9004-77-7) is a nonionic surfactant and solvent. Also marketed as DCP 208 and Adeka Carpol M2.

Textile and leather: leveling and dispersing agent for dye uptake uniformity
Metalworking and industrial cleaning: solubilizes oils in water-based cutting fluids and degreasers
Personal care: solvent and emulsifier in rinse-off formulations
Paper manufacturing: improves pigment dispersion in surface sizing and coating formulations
Its butyl-capped polyethylene glycol structure delivers controlled hydrophilic-lipophilic balance for emulsification and dispersion.

Good to know: Buyers should specify chain length or equivalent grade designation when sourcing.
