Data source

Materials and methods

Results and discussion

Any other information on results incl. tables

The substance is formally an ether of isoborneol with two (iso)propanole chains. It has a low solubility in water, for renally

excretion improvement by glucuronidation or conjugation with sulfate or acetate etc. is necessary. This may be possible

directly on the alcohol–group of the side chain or after a hydroxylation of a methyl-group of the molecule.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): no bioaccumulation potential based on study results
Ether bindings are split up during metabolism in mammalian organism slowly. 
The decomposition of the molecule should lead to isoborneol, which is excreted mainly via lungs (about 70 percent) due to its
volatility or hydroxylated and excreted with urine. Isoborneol can also be secreted by gall bladder with bile. This metabolic
pathways seems also possible for the substance itself.
Executive summary:

There are no toxicokinetic studies for this substance, but a transfer of knowledge about well known bicyclic terpene hydrocarbons like borneol, camphen, pinenes can give relevant hints for metabolism:

The substance is formally an ether of isoborneol with two (iso)propanole chains. It has a low solubility in water, for renally excretion improvement by glucuronidation or konjugation with sulfate or acetate etc. is necessary. This may be possible directly on the alcohol–group of the side chain or after a hydroxylation of a methyl-group of the molecule.

Ether bindings are splitted up during metabolism in mammalian organism slowly.  The decomposition of the molecule should lead to isoborneol, which is excreted mainly via lungs (about 70 percent) due to its volatility or hydroxylated and excreted with urine.
