Executive summary:

The vapour pressure of Bis(2 -hydroxyethyl)oleylmethylammonium chloride, CAS Number 18448 -65 -2, EC Number 242 -332 -0, was estimated using MPBVP (v1.43), [EPI Suite version 4.11].

The study was assigned a reliability score of 2 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

The vapour pressure was estimated to be 3.7E-18 mm/Hg (4.93E-16 Pa) at 25 degrees C, modified Grain method.
