Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- CERVOLIDE does not meet the criteria to be as Eye irritant Category 2 according to the CLP Regulation (EC) No. 1272/2008.
- Executive summary:
The CERVOLIDE was tested in this study to determine his eye irritant potential according to the procedure is that suggested by Dr. Draize and described in "Appraisal of the safety of chemicals in foods, drugs amd cosmetics" published by the Association of Food and Drug Officials of the United States.
Observations and scoring by the Draize method were conducted immediately and 1 hour, 24 hours, 48 hours, 72 hours, 7 days and 14 days later. With 10%, conjunctival redness was observed in 3/3 animals at 1 hour and 24 hours. Reactions were absent by 48 hours. With 30%, conjunctival redness was observed in 3/3, 3/3 and 1/3 animals at 1 hour, 24 hours and 48 hours, respectively. Reactions were absent by 72 hours.With the neat material, conjunctival redness was observed in 3/3, 1/3 and 3/3 animals at 1 hour, 24 hours and 48 hours, respectively. Moderate conjunctival redness was observed in 2/3 animals at 24 hours. Chemosis was observed in 3/3 animals at 24 hours. Dose: 100 % Effects: eye effects; irritant effects Results: moderate conjunctival irritation which cleared within 72 hours
CERVOLIDE does not meet the criteria to be as Eye irritant Category 2 according to the CLP Regulation (EC) No. 1272/2008.
