Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 405 (Acute Eye Irritation / Corrosion)
- Principles of method if other than guideline:
- The Draize rabbit eye irritation procedure was used to evaluate Myristyl Myristate in six separate studies. In each study, 0.1 ml of diluted or undiluted Myristyl Myristate was instilled into one eye of each rabbit with no subsequent washing;
The untreated eye served as control.
The treated eyes were examined and gradded on the Draize eye irritation scale at 24, 48 and 72 h.
The undiluted ingredient produced only minimal eye irritation. - GLP compliance:
- not specified
