VIABILITY/MORTALITY/CLINICAL SIGNS

No clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.

 

IRRITATION

The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores0).The individual mean score for erythema/eschar and oedema for each of the three animals was therefore0.

 

COLORATION

No staining by the test item on the treated skin was observed.

 

CORROSION

Noirreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin.

 

BODY WEIGHTS

The body weights of all rabbits were considered to be within the normal range of variability.

Applicant's summary and conclusion

Interpretation of results:

not irritating

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Based upon the referred classification criteria (EEC Commission Directive 93/21/EEC of
April 27, 1993), ACETYLFURANOSIDE is considered to be “not irritating” to rabbit skin.

Executive summary:

To assess the primary skin irritation potential of ACETYLFURANOSIDE, a primary skin irritation study was performed in three (one male and two females) young adult New Zealand White rabbits.

 

The fur of the left flank was clipped and 0.5 g of ACETYLFURANOSIDE was applied epicutaneously to an area of approximately 6 cm²and then covered with a semi-occlusive dressing for approximately four hours. The skin reactions (erythema and eschar, as well as oedema formation) were evaluated at 1, 24, 48 and 72 hours after removal of the dressing and test item.

 

The test item did not elicit any skin reactions at the application site of any animal at any of the observation times (all scores 0). The individual mean score for erythema/eschar and oedema for each of the three animals was therefore 0.

 

The test item caused no staining of the treated skin.

 

No corrosive effects were noted on the treated skin of any animal at any measuring interval.

 

Following evaluation of the experimental data according to the EEC classification criteria, ACETYLFURANOSIDE is classified as "not irritating" to rabbit skin.
