Applicant's summary and conclusion
- Interpretation of results:
- other: Weakly Sensitizing
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The test compound D &C yellow no. 11 induced delayed type skin sensitization in guinea pig and is found to be a sensitizing to the skin of guinea pigs.
- Executive summary:
Modified Buehler test was performed to study the sensitizing potential ofD &C yellow no. 11 to the skin of Guinea pigs.
The induction phase was accomplished with 24 hr occluded patch in nuchal area once weekly for three consecutive weeks following 2 week resting period. Pigs were initially challenged with dye used during the induction phase and then with the concentration of 1.0, 3.0 and 10%.Thereafter the patches were removed and the guinea pigs were rested for 24 hrs depilated with a chemical depilatory and evaluated and scored for erythema and edema.
D &C yellow no. 11 at a challenge concentration of 10% elicited delayed skin sensitization in 11 of 13 animals and hence is a weak sensitizer. Lower concentrations did not elicit statistically significant response.
According to the publication, the test material is a skin sensitizer.
