Description of key information

Bioaccumulation: aquatic / sediment

From BCFBAF (v3.00) model of EPI suite Program, the estimated bio concentration factor (BCF) for 2-hydroxypropyl octadec-9-enoate is 2006 L/kg whole body w.w which exceed the bio concentration threshold of 2000. Thus it is concluded that 2-hydroxypropyl octadec-9-enoate is expected to bioaccumulate in the food chain.

Additional information

Bioaccumulation: aquatic / sediment

Three results including different predicted data from validated models and experimental data from authorative database for bioaccumulation (BCF) endpoint of target chemical 2-hydroxypropyl octadec-9-enoate (Cas no. 1330-80-9) were summarized as follows:

 

First prediction done using BCFBAF (v3.00) model indicate the estimated bio concentration factor (BCF) for 2-hydroxypropyl octadec-9-enoate is 2006 L/kg wet-wt which exceed the bio concentration threshold of 2000. Thus it is concluded that 2-hydroxypropyl octadec-9-enoate is expected to bioaccumulate in the food chain. 

Other predicted database PBT profiler indicates the Bioaccumulation factor (BCF) for test substance 2-hydroxypropyl octadec-9-enoate was estimated to be 2000 L/kg wet-wt at 25 deg.C. Based on the BCF concentration factor it is concluded that the test chemical 2-hydroxypropyl octadec-9-enoate is bioaccumulative in nature as it equal to the BCF criteria of 2000.

All above predicted results of target supported by experimental data of read across chemical Isopropyl Myristate (Cas no. 110-27-0) which suggest an estimated BCF of 2800 was calculated in fish for isopropyl myristate, using an estimated log Kow of 7.17 and a regression derived equation. This BCF suggests the potential for bioconcentration in aquatic organisms is very high.

 

Thus based on the above information for bioaccumulation endpoint, it can be concluded that the test substance 2-hydroxypropyl octadec-9-enoate (Cas no. 1330-80-9) is expected to be bioaccumulative in aquatic environment.
