Results and discussion

Toxicokinetic / pharmacokinetic studies

Details on absorption:
Considering the use of 3-oxoglutaric acid, as an intermediate for the preparation of other chemicals; the most likely route of exposure is dermal, followed by inhalation that shall result in the absorption of chemical within the living system. However, considering that in an industrial environment the use of gloves and mask is prevalent, dermal absorption shall also be limited. Also the particle size of glutaric acid is not of an inhalable size thus the absorption through the inhalation route is also unlikely.


Details on distribution in tissues:
3-oxoglutaric acid is very soluble in water as well as methanol. Thus, it is highly likely that this substance, if absorbed is likely to be distributed to the other parts of the living system through the blood and lipids. But given its low bio-concentration factor (BCF) of 3.2, 3-oxoglutaric acid shall not bio-accumulate in the living system and is likely to be excreted out of the body.


Details on excretion:
3-oxoglutaric acid is very soluble in water as well as methanol. Thus, it is highly likely that this substance, if absorbed is likely to be distributed to the other parts of the living system through the blood and lipids. But given its low bio-concentration factor (BCF) of 3.2, 3-oxoglutaric acid shall not bio-accumulate in the living system. As a general rule, the chemicals that do not bio-accumulate are likely to be excreted out of the body either through urine, bile or faeces.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: no or low bio-accumulation potential based on the properties
Based upon the physico-chemical properties and bio-concentration factor of 3-oxoglutaric acid it has been deduced that the chemical has potentially no or low bio-accumulative property and shall be eliminated from the body system through urine, bile or feaces posing no danger to the living organism.

Executive summary:

Based upon the physico-chemical properties and bio-concentration factor of 3-oxoglutaric acid it has been deduced that the chemical has potentially no or low bio-accumulative property and shall be eliminated from the body system through urine, bile or feaces posing no danger to the living organism.
