Description of key information

An experimental melting point of <-20 deg C has been determined for the chemical subject to REACH registration. Melting point data are also available for three read-across chemicals. These 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 various aliphatic acids via ester groups. The category members are all liquids at room temperature, and all exhibit melting points <-20⁰C. The individual values for the read-across category members, as well as the chemical subject to this registration are given in the individual melting point study records in this file.

The MPBPWIN module (v1.43) of the U.S. EPA EpiSuite program (Copyright 2000 -2012) was used to calculate a melting point for the subject chemical. The value obtained bu this method was 89.10 ⁰C. This calculated value is not consistent with the actual observation that the material is a liquid at room temperature.
