Allergenicity evaluation of Bioban CS-1135 in experimental animals.
An industrial preservative, Bioban CS-1135, was evaluated for its contact allergenicity by means of multiple-dose guinea-pig maximization test and non-radioactive murine local lymph node assay. In the guinea-pig test, an induction dose of 0.5% Bioban CS-1135 sensitized all animals of the group. The dose-response study of the elicitation phase determined a minimum elicitation dose of 5% for positive skin reactions. In the murine assay, Bioban CS-1135 at doses of 10% and more exerted significant effects on lymphoid cell proliferation. Although the data clearly designated Bioban CS-1135 as a skin sensitizer, its relative potency was ranked lowest among skin-sensitizing biocides previously evaluated in this laboratory.
