PPG-2 myristyl ether propionate was found to have a boiling point of 235 - 254 °C at 101325 Pa, resulting in an average of 245 °C.
Executive summary:

In accordance with OECD Guideline 103 (Boiling Point), the boiling point for PPG-2 myristyl ether propionate was determined by use of a Siwoloboff technique. The sample was heated gradually within a tube and the boiling temperature was noted to be the point at which, on momentary cooling, a string of bubbles tops and liquid suddenly rises in the boiling capillary of a thermometer in close contact with the tube. The experiment was repeated in quadruplicate and the average of the initial and final boiling point (°C) calculated. PPG-2 myristyl ether propionate was concluded to have a boiling point of between 235 - 254 °C at 101325 Pa, resulting in an average of 245 °C.

Description of key information

The average boiling point of PPG-2 myristyl ether propionate was determined to be 245 °C at 101325 Pa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
245 °C

Additional information

A key study was undertaken according to the Siwoloboff technique specified in OECD Guideline 103 (Boiling Point), without deviation, to determine boiling point. The resulting value has been assigned a Klimisch score of 1 (reliable without restriction) and is suitable for regulatory purpose.
