Description of key information

Glycol ethers are not considered to have a pH. Glycol ethers are extremely weak acids, with pKa values typically of 16-18. The pH is defined as the –log of the hydrogen concentration. The pH-value is usually only relevant for aqueous solutions. In the case of glycol ethers being very weak acids, there is very little hydrogen ion dissociated. In addition there is almost no water present in the glycol ether. Thus dissociation does not occur.
