Conclusions:
Biodegradation half-life of test substance 2-Buten-1-ol, 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)- in soil was estimated to be 75 days (1800 hrs).
Executive summary:

Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half-life period of 2-Buten-1-ol, 2-methyl-4-(2,2,3-trimethyl-3-

cyclopenten-1-yl)- (CAS No. 28219 -60 -5) in soil was obtained to be 75 days (1800 hrs). Based on this half-life value of 2-Buten-1-ol, 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-, it is concluded that the chemical is not persistent in the soil environment.
