Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Reaction mass of 2-ethylpropane-1,3-diol (DMP) and 5-ethyl-1,3-dioxane-5-methanol (CTF) and propylidynetrimethanol (TMP) comprises of a number of components, the main constituents are CTF (cyclic trimethylolpropane), DMP (di-methylolpropane) and TMP (2 -ethyl-2 -hydroxymethyl-1,3 -propanediol).

 

A test conducted to OECD guideline 301A indicated that the Reaction mass overall can be considered as inherently biodegradable (90% biodegradation in 35 days). This conclusion is confirmed by individual tests on the separate components. The substances CTF (cyclic trimethylolpropane) and DMP (di-methylolpropane) are readily biodegradable (84% after 21 days with a 14 day lag phase and 81% after 14 days, respectively in tests conducted to OECD 301A). The substance TMP is inherently biodegradable (80% in 3 days in a test conducted to OECD 302B).

 

Simulation tests on soil and sediment were waived. This is because the exposure to these compartments is not likely and it can be expected that all components of Polyol TD have a low potential for adsorption to soil and sediment (log Pow < 3).
