- Concentration (if solution): undiluted

Duration of treatment / exposure:
up to 4 hours or until break through
Observation period:
Test substance: 3 min to 4 hours or until break through
Negative control: 60 min
Positive control: continuosly until break through
Details on study design:
4 tests were performed for the test item, one test for the positive, negative ant eht color (blank) control.
The experimental design of this study consisted of a qualification screen with the CDS (to determine if a color change can be detected) and a categorization screen (to categorize weak acids/bases and strong acids/bases), which were performed as a pretest, and a definitive Corrositex® assay.
The Corrositex® assay was evaluated on the basis of the color change of the CDS. The time that a color change was observed was recorded manually and the break through times of the four replicates was used to determine the corrosive potential of the test substance. For the qualification screen, 150 μL of the test substance was added to the CDS screening tube. If the test substance failed to produce a color change in the CDS within one minute, the test substance could not be analyzed in this system, and no further testing was required. In addition, one vial was used for the PC, NC and for the color (blank) control, each. A membrane disc coated with the biobarrier matrix was placed into one vial containing the CDS and approximately 500 μL of the test substance was added onto the membrane disc. An electronic time clock was started with the application. The vial was observed for three minutes for any change in the CDS. If no color change was observed within three minutes, the remaining membranes were
treated with the test substance. An electronic time clock was started with each application. The vials were observed continuously for the first ten minutes. Thereafter the vials were observed for approximately ten minutes around the time points relevant for evaluation or until break through of the test substance occurred. The elapsed time between test-substance application and the first change in the indicator solution (i.e. barrier
penetration) was recorded.

Based on the observed results and applying the evaluation criteria described it was concluded, that 3-Amino-butan-1-ol shows a corrosive potential in the Corrositex® - Skin Corrosion Test under the test conditions chosen. The mean break through time

determined in the in vitro membrane barrier test was 28 minutes and 18 seconds.
