Additional information

All of the components in the Reaction mass of 1,3-Propanediol, 2-(hydroxymethyl)-2-[(methoxymethoxy)methyl]- and 1,3-dioxane-5,5-dimethanol are stable to hydrolysis i.e. the estimated half-life of the components is greater than one year under typical environmental conditions.

The Reaction mass of 1,3-Propanediol, 2-(hydroxymethyl)-2-[(methoxymethoxy)methyl]- and 1,3-dioxane-5,5-dimethanol and all of its components can not be classified as readily biodegradable.

The logKow values of all of the major componments of Reaction mass of 1,3-Propanediol, 2-(hydroxymethyl)-2-[(methoxymethoxy)methyl]- and 1,3-dioxane-5,5-dimethanol are reported to be <3 (see Section 4.7, partition coefficient). According to Column 2 of Annex IX of the REACH regulation, no study is required if the logKow is below the trigger of 3 as the substance can be expected to have a low potential for bioaccumulation.

Based on physicochemical properties (i.e. Log Pow = -0.9) the substance can be expected to have a low potential for adsorption. According to Column 2 of Annex VIII of the REACH regulation, no study is required if the logPow is below the trigger of 3 as the substance can be expected to have a low potential for adsorption.
