14-Day Cumulative Irritation Patch Test in Subjects With Normal Skin

The objective of this study is to determine the ability of the study material to cause irritation to the skin of humans under controlled patch test conditions. Substances that come into contact with human skin need to be evaluated for their propensity to irritate and/or sensitize. This testing is a modified primary irritancy patch test that can detect weak irritants that require multiple applications to cause a skin reaction.
