Results and discussion
In vivo
- Irritant / corrosive response data:
- Only the corrosivity was determined, as such no information is provided on individual animal scores for erythema and edema. The conclusion of the assay was that the material tested was corrosive, however there is no information on the time taken to produce corrosivity, i.e. 4 mins, 1 hour or 4 hours.
Considering the pH and the irritancy of the structurally related compound 2-amino-2-methylpropanol it is likely that it is corrsoive at 4 hours rather than 1 hours
Any other information on results incl. tables
Only the corrosivity was determined, as such no information is provided on individual animal scores for erythema and edema. The conclusion of the assay was that the material tested was corrosive.
Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Criteria used for interpretation of results: expert judgment
- Conclusions:
- The substance appears to be corosive. Considering the high pH of the test material in a 0.1M aqueous solution (pH11.1) it is not surprising that the substance is corrosive.
- Executive summary:
2 -Aminobutanol was tested for corrosivity using a Draize protocol, where 6 Albino Rabbits were exposed under occlusive conditions to the test material for 4 hours. Under the conditions of the assay the substance was Corrosive.
