Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The substance is an UVCB generated by the reaction of glycerol, propane-1,3-diol and trimellitic anhydride. It is expected that the starting materials or their hydrolysis products are released in the course of metabolism. Esterases present in the skin, in the interstinal tissues and in liver and plasma can efficiently cleave similar esters.

Additional information

The dermal absorption has been modeled according to Fitzpatrick et al.. The log Kp calculated with a mol wt. of 920 and a logKow of 0.3 is -12.2 indicating a marginal potential for skin penetration.
