Applicant's summary and conclusion

Interpretation of results:

other: not classified

Remarks:

Criteria used for interpretation of results: EU

Conclusions:

- is slightly irritant for the eye (Max. O.I = 9.3) according to the classification established in the
Journal Officiel de la République Française dated July 10th, 1992.
- must not be classified according to the criteria for the classification, packaging and labelling of
dangerous substances in compliance with the E.E.C. Directive n° 67/548 and 93/21.

Executive summary:

The product LCA01006 was instilled, as supplied, into the eye of three New Zealand rabbits at the dose of 0.1 ml, according to the experimental protocol established on the basis of the official method as defined in the O.E.C.D. guideline n° 405 dated February 24th, 1987 and the test method B.5 of the directive 92/69/E.E.C. dated December 29th, 1992.

The ocular reactions observed during the study remained slight and only recorded at the conjunctivae level: redness 1 hour after the test product instillation and totally reversible between the 3rd and the 4th day of the test, associated with a slight chemosis in the 3 animals on examination time 1 hour only.

In conclusion, the result obtained, enable to conclude that the test product LCA01006:

- is slightly irritant for the eye (Max. O.I = 9.3) according to the classification established in the Journal Officiel de la République Française dated July 10th, 1992.

- must not be classified according to the criteria for the classification, packaging and labelling of dangerous substances in compliance with the E.E.C. Directive n° 67/548 and 93/21.
