Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis as a function of pH

In accordance with column 2 of REACH Annex VIII, the study does not need to be conducted, because the substance is readily biodegradable.

Additional information

Additional information on stability:

In air, the photodegradation of 1,3 -butanediol by OH-radicals was estimated to be 14.2329 E-12 cm³/molecule*sec, leading to a half-life of approx. 27 hours (1.1 days) (ECT, 2008).

First order rate constants for photochemical oxidation in water by OH radicals were reported to be 2.2E09 L/mol*sec at pH 7 (Buxton et al., 1988; RL4).

No data on phototransformation in soil are available.
