4-hydroxybenzotriazole 0.32%

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): low bioaccumulation potential based on study results
Based on the physicochemical data and the supporting study by Hoffmann the toxicokinetic properties of Benzotriazole are assesssed.
Executive summary:

Absorption: for the dermal and oral route, an absorption of 100% are assumed,

for the inhalative route no relevant absorption is estimated and 10% are assumed.

Distribution: no information

Metabolism and Excretion: metabolism rate is rather low (supporting study) and no Phase II reactions may occur.

Renale and fecal excretion are the prominent excretion routes.
