Additional information

According to column 2 of REACH Annex IX, study does not need to be conducted since Guaiacol is readily biodegradable. However, a study quoted as Klimisch 3 (Alexander & Lustigman, 1966) indicated biodegradation of substituted benzenes by soil microflora. Based on loss of UV absorbancy, the authors found that guaiacol was degraded by soil microorganisms in 4 days.
