Key value for chemical safety assessment
Additional information
The vapour pressure of the substance "Reaction mixture of glycerol-1,3-di(acetate), glycerol acetate and triacetin"
(EC 905-964-4) was determined by QSAR calculation with SPARC (v4.6).
Publicly available data for the triacetin component show a vapour pressure of 0.33 Pa at 25 °C and are within the above mentioned range and therefore supporting
