Toxicokinetic / pharmacokinetic studies

Details on absorption:
0.014 and 0.026 mg DCHA/ml blood were determined indicating that dicyclohexylamine penetrate the alveolar membrane and enter the blood.
Details on distribution in tissues:
0.014 and 0.026 mg DCHA/ml blood were determined indicating that dicyclohexylamine penetrate the alveolar membrane and enter the blood.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: penetrated the alveolar membrane and entered blood stream
Executive summary:

Following inhalation exposure to DCHA, it was determined in blood indicating that dicyclohexylamine penetrates the alveolar membrane and enters the blood.
