Applicant's summary and conclusion

Executive summary:

Due to the virtually constant mass loss above 90 °C the vapour pressure of DCHA-isostearate was calculated between 45°C and 90°C. The calculated mass loss within this temperature range is 0.87 mg (corresponds to 8.7 %), which results in a vapour pressure of 1.0 Pa at 20 °C and 1.5 Pa at 25 °C.
