Conclusions:
The autoignition temperature (liquids) for 2-(2-methylpropoxy)ethanol was found to be 265 °C at 1010 hpa.
Executive summary:

An experiment was undertaken in line with ASTM E659-14 (Standard Test Method for Autoignition Temperature of Liquid Chemicals) to determine the autoignition temperature of 2-(2-methylpropoxy)ethanol. The appearance of a flame within the flask and a rise in temperature indicated that auto-ignition had taken place. The lowest internal flask temperature at which hot-flame ignition occurred (i.e. the autoignition temperature) for 2-(2-methylpropoxy)ethanol was 265 °C at an atmospheric pressure of 1010 hpa.

Description of key information

An autoignition temperature of 265 °C was determined for liquid 2-(2-methylpropoxy)ethanol at an atmospheric pressure of 1010 hpa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
265 °C

Additional information

A Klimisch score of 1 (reliable without restriction) has been recommended for the endpoint conclusion given that it was obtained in a key study performed according to ASTM E659-14 (Standard Test Method for Autoignition Temperature of Liquid Chemicals). No deviation from the protocol was reported.
