Key value for chemical safety assessment
Additional information
The vapour pressure of the test substance 2,2-bis(hydroxymethyl)propane-1,3-diyl didocosanoate (CAS: 68258-72-0) was determined by QSAR calculation with SPARC (v4.6). The results are 4.32E-22 Pa, 5.28E-36 Pa, 1.58E-46 Pa for the diester, triester and tetraester components, respectively.
