Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 430 (In Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test Method (TER))
- Principles of method if other than guideline:
- The test material was applied to the epidermal surface of three skin discs for a contact period of 24 hours. At the end of the contact period the test material was removed using a jet of warm tap water. Corrosive substances produce an irreversible loss of normal stratum corneum integrity and function, this is measured as a reduction in the inherent TER. test materials that give a mean electrical resistance of 5 kOhm or less are considered likely to be corrosive in vivo. The TER was measured using a low voltage alternating current electronic databridge.
- GLP compliance:
- yes (incl. QA statement)

Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Potential to cause corrosion Criteria used for interpretation of results: EU
- Conclusions:
- The mean TER recorded for the 24 hour test material contact period was less than 5 kOhm.
Following assessment of the data the test material is considered to have the potential to cause corrosion in vivo.
