Other Names

Diethylene glycol monobutyl ethe

The formula



Butyl CARBITOL glycol ether can be considered a slower-evaporating analog of Butyl CELLOSOLVE glycol ether. It can be used in combination with Butyl Cellosolve glycol ether to lower the evaporation rate and increase the hydrophobicity of the solvent package. Yet Butyl CARBITOL glycol ether offers 100% water solubility.
