Tetrazolium salt, MTT Colorimetric Assay를 이용한 Mouse Fibroblast에 대한 화장품원료 물질의 세포독성 평가

Cytotoxicity Evaluation of Cosmetic Materials to Mouse Fibroblast : by Tetrazolium salt, MTT Colorimetric Assay

The in Vitro chemosensitivity of fibroblast cell strains was determined using a semiautomated tetrazolium-based colorimetric assay(MTT assay) to 16 cosmetic materials. This assay is useful method to evaluate toxic effects of the chemicals. From assay results, we determined that the preservatives are more toxic than moisteurizers. The chemicals in the same group have a different toxicity. That is, in preservatives, Germall -115 is more toxic than Danisol -M, -p, and in surfactant sodium laurel sulfate than Myrj 52, and in moisteurizers, 1, 3-butylene glycol is more safe than the others. When the results from this assay for preservatives were compared with patch test results, good correlation was observed. Forthemore, this assay method can be used together with Patch test for the evaluation of the chemical toxicity, particularly in cosmetic field.
