Description of key information
Bioaccumulation: aquatic / sediment:
The estimated bio concentration factor (BCF) for 2-isopropyl-5-methylcyclohexanone is 47.8 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000.Thus it is concluded that 2-isopropyl-5-methylcyclohexanone is not expected to bio accumulate in the food chain.
Additional information
Bioaccumulation: aquatic / sediment:
Five studies including Predicted model data and Experimental result for Bioaccumulation endpoint of target chemical 2-isopropyl-5-methylcyclohexanone (Cas no. 1074-95-9) and its relevant read across chemical which is100% structurally similar to targetwere reviewed to summarize as follows:
In a prediction done using the BCFBAF (v3.01) model of the EPI suite Program (2017), the estimated bio concentration factor (BCF) for target chemical 2-isopropyl-5-methylcyclohexanone is 47.8 L/kg wet-wt.
Another prediction model PBT profiler; 2017 indicated that the Bioaccumulation factor (BCF) was predicted to be 48 L/kg wet-wt at 25 deg.C for 2-isopropyl-5-methylcyclohexanone.
Further, as per Chemspider - ACD/PhysChem Suite prediction model, the Bioconcentration factor (BCF) for target chemical 2-isopropyl-5-methylcyclohexanone was predicted to be 147.25 at pH 5.5 and 7.4 at temperature 25 deg.C.
Above all results are supported by reliable prediction database i.e Scifinder; 2017 for read across substance trans-menthone (Cas no. 89-80-5) indicated the Bioconcentration factor (BCF) for was predicted to be 73.1 at pH 1-10 and temperature 25 deg.C.
In addition, a study from authorative database i.e HSDB by US EPA; 2017 for same read across chemical i.e trans-menthone (Cas no. 89-80-5) indicated an estimated BCF of 15 was calculated for menthone, using a water solubility of 688 mg/l and a regression derived equation. This BCF suggests the potential for bioconcentration in aquatic organisms is low.
All studies for target and read across indicate the BCF factor is in the range of 15 -147.25(L/kg wet-wt or dimensionless) concluded test substance chemical 2-isopropyl-5-methylcyclohexanone (Cas no. 1074-95-9) is non Bioaccumulative in aquatic environment as all not exceed the BCF criteria of 2000.
