Description of key information

Examination of the chemical structure of 1-phenoxypropan-2-ol (propylene glycol methyl ether) shows that there is no functional group that could dissociate. The substance does not contain both, acidic or basic functional groups. 1-Phenoxypropan-2-ol (propylene glycol methyl ether) is not an ionisable organic substance and as non-ionisable ether-alcohol will tend not to dissociate in water under normal environmental conditions. Hence, according to column 2 of Annex IX of REACH this study does not need to be conducted.
