Description of key information

Experimental water solubility data are available for the chemical to be registered (water solubility = 8.8E-5 g/L). Water solubility data are also available for four read-across chemicals. The read-across chemicals are included in the Glycol Esters Category submitted by the American Chemistry Council for the U.S. Environmental Protection Agency as a contribution to the U.S. EPA High Production Volume Chemical Program. All members of this category have similar molecular structure and functional groups. The functional groups in common are aliphatic ester groups and glycol ether groups. The glycol ether groups, joined together in one to four units, are end-capped with aliphatic acids via ester groups. The water solubilities of the test substance and the read-across chemicals are qualitatively described as of low water solubility.

The WATERNT module (v1.01) of the U.S. EPA EpiSuite program (Copyright 2000 -2012) was used to calculate a water solubility for the subject chemical. The value obtained bu this method was 0.015889 mg/L and is consistent with the values for the similar read-across chemicals.
