98 °C at 102.21 kPa (closed cup)

Key value for chemical safety assessment

Additional information

The flash point of the substance fatty acids, tall-oil, butyl esters (CAS 67762 -63 -4) was obtained from measurement of a similar substance with EU method A.9 using an equilibrium closed cup method.

Justification for read-across:

CAS-No. 163961-32-8 (fatty acids, C16-18 and C18 unsatd., branched and linear, butyl esters) and CAS-No. 67762-63-4 (fatty acids, tall-oil, butyl esters) are structural similar due to the specification of 67762-63-4. This substance contains butyl esters of fatty acids with the following chain length: C16 < 10%, C20 < 10%, ∑ C18 unsatd. 40-100%. Therefore read-across for some physico-chemical endpoints is possible.
