Executive summary:

In a primary dermal irritation study, 3 New Zealand albino rabbits obtained from Charles River Deutschland GmbH weighing 2.3-2.8 kg were dermally exposed to Reactive Navy FC63805 in deionized water to an area of 25 cm2 on the dorsal region of the body with hair removed with an electric clipper. Test sites were covered with a semi-occlusive dressing for 4 hours. Animals were then observed for 3 days. Irritation was scored according to DRAIZE.

Interpretation of results:

GHS criteria not met

Conclusions:

Reactive Navy FC63805 is classified as not irritating as a result from the eye irritation experiment in New Zealand albino rabbits according to CLP criteria.

Executive summary:

In a primary eye irritation study according to OECD 405, 100 mg of Reactive Navy FC63805 was instilled into the conjunctival sac of the left eye of 3 New Zealand albino rabbits obtained from Charles River Deutschland GmbH weighing 3.3-3.7 kg for 24 hours. Treated eyes were washed with isotonic saline at approx. 37 degrees C 24 hours after administration and at all other designated examination times at which the treated eyes still showed discharge or at which a corneal examination with fluorescein sodium solution took place. Animals were then observed for 3 days. Irritation was scored by the method described previously.

In this study, Reactive Navy FC63805 is not considered an eye irritant.

Additional information

In a primary dermal irritation study, 3 New Zealand albino rabbits were dermally exposed to Reaktiv Marineblau FC 63805 in deionized water to an area of 25 cm² on the dorsal region of the body. Animals were then observed for 3 days. Irritation was scored according to DRAIZE. The mean score for erythema was 0.7 (max 3), and mean score for edema was 0 (max 0), therefore, Reaktiv Marineblau FC 63805 is slightly irritating to the skin.

In a primary eye irritation study, 100 mg of Reaktiv Marineblau FC 63805 was instilled into the conjunctival sac of the left eye of 3 New Zealand albino rabbits for 24 hours. Animals were then observed for 3 days. No effects on cornea or iris have been reported. The mean conjunctivae score was 0,44. The conjuctivae and chemosis maximum scores were 1 and 2, respectively. Scores for the iris and cornea were both 0. Therefore, results conclude Reaktiv Marineblau FC 63805 is not considered an eye irritant.

Justification for classification or non-classification

All signs of slight irritation were fully reversible in rabbit eyes and on rabbit skin. No positive indication of skin or eye irritation or any signs of corrosion were found. The substance is not classifiable according to CLP criteria.
