Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- Tetrabromo Bisphenol-A, Lot #R6-FD2, did not cause delayed hypersensitivity in guinea pigs.
- Executive summary:
Tetrabromobisphenol-A, Lot # R6/FD2, was dermally applied to ten guinea pigs for a total of nine six-hour insult periods. A positive control group consisting of 10 guinea pigs was treated with 2,4 dinitrochlorobenzene. Approximately fourteen days after the last senstizing exposure, the animals were challenged in the same manner at both the site of sensitizing and a second challenge site. 48 hours after the first challenge, a second challenge was made. A positive reposnse was elicited by the animals receiving 2,4 dinitrochlorobenzene at challenges I and II. Erythema was observed during induction at 7 hours post doses 3 and 9, 24 hours post doses 3, 6, and 9, and 48 hours post doses 3, 6, and 9. No irritation was observed during induction or challenge periods with Tetrabromo Bisphenol-A.
Tetrabromo Bisphenol-A, Lot # R6/FD2, did not cause delayed hypersensitivity in guinea pigs.
