Details on test animals or test system and environmental conditions:
3 male albinos rabbits, numerated A4789, A4790 and A4791 of new-zealand strain, originating from the Elevage de Gérome (Quartier Labaste – 40260 Linxe) were kept during a 7-day acclimatisation period.

The product MADECASSOSIDE was applied, as supplied, at the dose of 0.5g, under semi-occlusive dressing during 4 hours on an undamaged skin area of 3 rabbits, according to an experimental protocol established from the O.E.C.D. guideline (n° 404 dated July 17th, 1992) and the method B.4 of the E.E.C. directive n° 92/69 dated December 29th,1992.
It was only noted a slight erythema, in 1 animal on the reading time 24 hours.
The results obtained, in these experimental conditions, enabled to conclude that the test product MADECASSOSIDE, according to the scales of interpretation retained:
- is non irritant to skin (PSi = 0.2) according to the classification established in the Journal Officiel de la République Française dated February 21st, 1982,
- and, must not be classified, according to the criteria for classification, packaging and labelling of dangerous substances in compliance with the E.E.C. Directives 67/548 and 96/45.

Interpretation of results:
other: not classified
Conclusions:
The results obtained, in these experimental conditions, enabled to conclude that the test product MADECASSOSIDE, according to the scales of interpretation retained:
- is non irritant to skin (PSi =0.2) according to the classification established in the Journal Officiel
de la République Française dated February 21st, 1982, - and, must not be classified, according to the criteria for classification, packaging and labelling of
dangerous substances in compliance with the E.E.C. Directives 67/548 and 99/45.
Executive summary:

The product MADECASSOSIDE was applied, as supplied, at the dose of 0.5g, under semi-occlusive dressing during 4 hours on an undamaged skin area of 3 rabbits, according to an experimental protocol established from the O.E.C.D. guideline (n° 404 dated July 17th, 1992) and the method B.4 of the E.E.C. directive n° 92/69 dated December 29th,1992.

Details on test animals or tissues and environmental conditions:
Three female albinos rabbits of New Zealand strain, numbered A4825, A4826 and A4827, originating from the Elevage de Gérome (Quartier Labaste – F40260 Linxe) were kept during a 5 day acclimatisation period. During the test, the animals weighed between 2.20kg and 2.37kg.
Animals were kept in individuals boxes, the environmental conditions were:
- temperature: between 19 °C and 21 °C
- relative humidity: between 45% and 52%
Vehicle:

Amount / concentration applied:
A quantity of 0.1 g of the pure test product was instilled into one eye of each rabbit
Number of animals or in vitro replicates:

Irritant / corrosive response data:
The ocular reactions observed during the study remained slight and only recorded at the conjunctivae level: very slight redness in the 3 animals on examinations times 1, 24 and 48 hours associated with a very slight chemosis in 2 animals only at the reading time 1 hour.

The result obtained, in these experimental conditions, enable to conclude that the test product MADECASSOSIDE:
- 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.
- and, 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 99/45.


 


NOTE :
If no reaction is observed at 72 hours (D3) after instillation, the study is finished. In case of persistent reactions, additional observations can be carried out at Day 4 (D4), to Day 21 (D21) in order to determine the reversible character of the lesions observed.

Interpretation of results:
other: not classified
Conclusions:
The result obtained, in these experimental conditions, enable to conclude that the test product MADECASSOSIDE:
- 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.
