Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 435 (In Vitro Membrane Barrier Test Method for Skin Corrosion)
- Version / remarks:
- Adopted 19 July 2006
- Deviations:
- no
- Principles of method if other than guideline:
- Corrositex test is a standardized and reproducible method that can be employed to determine potential corrosivity and determine the Packing Group classification of specified categories of chemical compounds under the hazardous materials transportation regulations administered by the U.S. Department of Transportation (DOT) and international dangerous goods codes. The Corrositex test predicts the in vivo corrosive potential or a chemical compound or mixture by using as an endpoint the time it takes for the chemical to permeate through or destroy a synthetic biobarrier. When the chemical has passed through this biobarrier, a visual change is produced in a proprietary Chemical Detection System (CDS).

Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- The results of these studies indicated that the samples were compatible with the Corrositex system and were classified as Category 2 material. The results obtained from the evaluation of three different samples with four replicates per sample were highly reproducible, demonstrating that mean time of > 60 minutes was required to destroy the synthetic biobarriers. These findings lead to the designation of these samples containing different ratio's of MAHP and MAES as a non-corrosive. To confirm the non-corrosivity, an additional in-vivo test was scheduled.
