In vitro test system
- Test system:
- artificial membrane barrier model
- Vehicle:
- unchanged (no vehicle)
- Details on test system:
- SOURCE AND COMPOSITION OF MEMBRANE BARRIER USED
- Was the Corrositex® test kit used: Yes (InVitro International, Irvine CA, USA)
- Components: The test system consists of two components: a proteinaceous macromolecular gel (= synthetic biobarrier) on a permeable membrane and a fluid, the Chemical Detection System (CDS)
- Apparatus and preparation procedures: The biobarrier was produced on the day the assay was performed. The entire contents of the biobarrier diluent vial were added slowly to the matrix powder to ensure complete and uniform solubilisation. The vial containing the solution was placed in a water bath on a heating plate set to 68°C with the stir switch set to maintain 200 rpm for the stir bar. The solution was warmed to 68 °C and stirred for 20 min to solubilise the biobarrier matrix. Then the heating plate was switched off and the solution was left to stand for 10 minutes. In the next step 200 μL of the solubilised matrix were pipetted onto the membrane discs. The membrane discs with the biobarrier were stored in the fridge (2 - 8°C) for a period of 5 hours before use.
WAS THE COMPATIBILITY TEST PERFORMED: For the qualification screen, 108.8 mg of the test item were added to the “qualification test tube”.
The test item induced a colour change in the CDS immediately and is therefore qualified for the determination of its skin corrosion potential with the Corrositex®-Test.
WAS THE TIMESCALE CATEGORY TEST PERFORMED: The categorisation screen was used to choose the appropriate scoring scale. The screen was performed by adding 103.2 mg (tube A) and 100.4 mg (tube B) of the test item to two different test tubes (A and B) which contained an acid resp. a base buffer. The content of the individual tubes was then mixed and the resulting colours were observed after one minute.
Since no colour change could be observed in either tube, two drops of the “confirm reagent” were added to tube B; this was mixed and the resulting colour was used to confirm the category. The categorisation kit and colour chart provided by Romer Labs Deutschland GmbH were used to determine the category. The test item was classified in category 2.
TEMPERATURE USED DURING TREATMENT: no data
METHOD OF DETECTION
- Chemical detection system (CDS) was used.
METHOD OF APPLICATION: A membrane disc coated with the biobarrier was placed into a vial containing the CDS and the control resp. test item was applied. Each replicate was observed until a break-through occurred or for the maximum observation time. First, one vial was exposed to the test item and a stop watch was started. The vial was observed for 3 min. continuously. Since no colour change or any other change in the CDS was visible within 3 minutes, the remaining 3 vials were exposed to the test item in 1 minute intervals.
NUMBER OF REPLICATES: 4 vials were used for quadruplicate measurement of the test item, 4 vials were used for the positive control, 4 vials were used for the negative control and 2 vials were used as colour reference for the CDS, respectively.
NUMBER OF INDEPENDENT EXPERIMENTS TO DERIVE FINAL PREDICTION: 1
PREDICTION MODEL / DECISION CRITERIA
- The test substance is considered to be corrosive to skin if observable changes in CDS solution were observed after > 30 - 60 min (Category 1C), > 3 - 30 min (Category 1B) and 0 - 3 min (Category 1A).
- The test substance is considered to be non-corrosive to skin if observable changes in CDS solution were not observed after > 60 min. - Control samples:
- yes, concurrent negative control
- yes, concurrent vehicle
- yes, concurrent positive control
- Amount/concentration applied:
- TEST MATERIAL
- Amount applied: ca. 500 mg (496.8, 505.1, 508.0 and 510.9 mg)
NEGATIVE CONTROL
- Amount applied: 500 µL
- Concentration: 10%
POSITIVE CONTROL
- Amount applied: ca. 120 mg (120.3, 122.9, 118.6 and 120.5 mg)
- Concentration: 100% (solid pellets) - Duration of treatment / exposure:
- 1 h (category 2)
- Number of replicates:
- quadruplicate measurement

- Other effects / acceptance of results:
- ACCEPTANCE OF RESULTS:
- Acceptance criteria met for negative control:
The negative control did not induce a change in the colour of the CDS reagent after > 60 minutes.
- Acceptance criteria met for positive control:
The positive control showed a distinct change in the colour of the CDS reagent in the time interval of 8 - 16 minutes (recorded breakthrough times: 11 - 14 minutes).
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification as corrosive required according to Regulation (EC) No. 1272/2008
- Conclusions:
- Under the conditions of this test, the test substance did not show corrosive properties towards the skin in the in vitro Membrane Barrier Test for Skin Corrosion using Corrositex®.
