Figure 2: (3-[4,5-dimethylthiazol-2-yl]–tetrazolium 2,5-diphenyl-bromide) colorimetric assay with NIH-3T3 fibroblasts, HaCat, and keratinocytes.Percentage of viability of NIH-3T3 fibroblasts on culture at 24 h and 48h (a and b), HaCat immortalized keratinocytes on culture at 24 h and 48h (c and d) and human keratinocytes (KC) on culture at 24 h and 48h (e and f) relative to the control (culture medium – corresponding to 100% viable cells) by MTT colorimetric assay. Medium: Culture medium for culturing the cells. V: Ethanol 0,01% + Propylene glycol 0,09%. R1, R2, R3, R4: resin at concentrations of 0.001%, 0.0001%, 0.00001% and 0.000001%, respectively. One-way ANOVA followed by Bonferroni test (P < 0.05)
