Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: expert judgment
Conclusions:
mild irritation reversible within 3 days.
Executive summary:

The objective of the study was to determine the potential eye irritation properties of different samples of which the chemical nature was not disclosed. The method used was generally that of Draize, Calvery and Woodward (Journ. Pharm. Exp. Therap. 82, 377 -390, 1944) and later described in "Appraisal of Safety of Chemicals in Foods, drugs and Cosmetics" (F.D.A. Div. Pharmacology, Draize J.H., 1959). The test solutions were made up by diluting the submitted samples of declared content of active matter with distilled water so that the content of active matter was reduced to 20% in each case. The tap water used for the control was London Tap Water. 0.1mL of the test solution (20% act. ingr.) was instilled into the conjunctival sac of one eye of each rabbit, the other eye serving as a control. In no case was the eye washed after instillation. For the sample of [Trade name], 3 rabbits were used. Readings were made visually and with the aid of an ophthalmoscope at 1, 2, 4, 6, 24, 48, 72 hours and 4 and 7 days after instillation and evaluated according to the Draize scoring method.
For the sample of [Trade name], mild irritation was observed which was reversible within 3 days.
