Biodegradability: 98% of 1,4-butenediol biodegraded in 5 days
Resuts of a guideline study of inherent biodegradability conducted
according to EU Method C.9 indicated 98% biodegradation in 5 days (BASF
AG 1993). The rapid decay of the test substance in this study indicates
that 1,4 -Butenediol (B2D) is readily biodegradable. The estimate of
biodegradability calculated using BioWin v. 4.10 also predicts that 1,4
-Butenediol is readily biodegradable (BioWin v4.10 2010). This
determination is supported by results of a second guideline-equivalent
study for inherent biodegradability of B2D and read-across to the
results of a guideline study for ready biodegradability conducted using
