Reference substance:

Reaction mass of 2-ethylpropane-1,3-diol and 5-ethyl-1,3-dioxane-5-methanol and propylidynetrimethanol

PBT status:

the substance is not PBT / vPvB

Justification:

Polyol TD is inherently biodegradable (95 % biodegradation in 35 days) and can therefore not be regarded as persistent in the environment.

Since the log Pow of all components of Polyol TD is below 4.5, Polyol TD does not have bioaccumulation potential.

Furthermore, Polyol TD does not exhibit any relevant toxicity to aquatic organisms or mammals.
