Applicant's summary and conclusion

Conclusions:
Fatty acids, C10 -20 neo, reaction products with diethylenetriamine is an UVCB substance. The main component is a mixture of bis-amides, derived from the amidation reaction between Fatty acids, C10-20-neo-, and diethylenetriamine. Fatty acids, C10-20-neo- is a complex mixture of tertiary carboxylic acids, with C19 being the main component.
Due to its complex composition, methods for the experimental measurement of vapour pressure are technically not applicable.
Based on the chemical composition, vapour pressure of the substance is estimated to be negligible, taking into account that the experimental vapour pressure value for Fatty acids, C10 - 20 neo, one of the starting materials and a minor component, is 0.009 Pa (at 20°C).
Estimated vapour pressure for the main component (bis amide derived from the amidation reaction between C19 neo fatty acid and diethylenetriamine) is 3.44 E-017 Pa (Modified Grain Method; MPBPWIN v.1.43, September 2010; US EPA).
