Conclusion on classification

Isobutyric acid, monoester with 2,2,4 -trimethylpentane-1,3 -diol is not classified for environmental effects due to the fact that it is readily biodegradable and does not meet the criteria for classification under the DSD-DPD or CLP. It also does not exhibit any of the grounds for concern listed for Chronic Category 4 under the CLP criteria.
