Key value for chemical safety assessment
Effects on fertility
Description of key information
NOAEL was considered to be 40 mg/kg/day for P and F1 generation when Crl:CD (SD)male and female rats treated with C.I. Basic Violet 1 orally by gavage.
Since no experimental and estimated data are currently available for reproductive toxicity and only read across data is available
for the target compound N-(4-((4-(dimethylamino)phenyl)(4-(phenylamino)naphthalen-1-yl)methylene)cyclohexa-2,5-dienylidene)-N-methylmethanaminium acetate (CAS No. 83803-79-6), conclusions and classifications are solely based on its read across chemicalsC.I. Basic Violet 1(CAS no 8004-87-3 and gentian violet (CAS no 548-62-9).
