According to ECHA guidance Chapter R.7c: Endpoint specific
guidance, Version 3.0 – June 2017, Section R.7.11.2 the following
applies: QUOTE: "In the case of readily biodegradable substances which
are not directly applied to soil it is generally assumed that the
substance will not enter the terrestrial environment and as such there
is no need for testing of soil organisms is required." UNQUOTE.
The substance (R)-(-)-butane-1,3-diol was shown to be readily
biodegradable, is fully miscible in water and does have a negative log
Pow (-0.9). Finally, no direct application to soil is known and indirect
exposure of soil is also unlikely. The substance is used as intermediate
and monomer in industrial processes, making exposure to soil very
unlikely. The professional and consumer uses in cosmetic, washing and
cleaning and pharmaceutical products do result in aqueous emissions to
sewage treatment plants, in which due to the ready biodegradability the
substance would be entirely biodegraded and thus, exposure to soil
through these uses of the substance is unlikely too. Thus, long-term
exposure to soil is not of concern and no testing for long-term toxicity
to soil microorganisms is required, based on exposure considerations.
