What is Corrositex®?

Corrositex® is an in vitro method used to determine the dermal corrosive potential of and assign U.N. Packing Group classification for chemicals and chemical mixtures.

Corrositex® has been designed as a replacement for the dermal corrosivity rabbit test based upon proprietary biomembrane and chemical detection technology developed by InVitro International.

This study is designed to comply with the standards set forth in the OECD Guideline for the Testing of Chemicals No. 435.

Why Use Corrositex®?

Saves Time Time Savings: Corrositex® testing can provide a Packing Group determination in a matter of minutes and no more than 4 hours, unlike animal testing which can take 2 - 4 weeks.
Accuracy Accuracy: More accurate than pH testing and is packing group specific.
Savings Cost Savings: Reduced shipping charges, additional cost savings workplace safety and MSDS development.

How the Test Works?

Corrositex® is a non-animal alternative toxicology test. Although not a classical "in vitro " test, Corrositex® uses a synthetic membrane-based detection system to determine the UN packing group classification of chemicals, consumer products or other hazardous materials. The results, expressed as a break-through time, correlate well with rabbit dermal corrosivity tests.

In the Corrositex® testing system, a glass vial filled with a chemical detection fluid is capped by a proprietary bio-barrier membrane, which is designed to mimic the effect of corrosives on living skin.

Corrositex® measures the time required for a test article to pass through a hydrated collagen matrix and supporting filter membrane. As the corrosive sample passes through or destroys this bio-barrier, the underlying liquid Chemical Detection System changes color or texture. The time it takes for the sample to break through the membrane is recorded and compared to a classification chart to determine corrosivity/noncorrosivity for assignment of the proper U.N. Packing Group classification for U.S. DOT or EPA compliance.
