Objective: To demonstrate the antibacterial activity of cosmetic products commonly used by\udthe community of Dhaka metropolis.\udMethods: A total of 10 categories of cosmetic samples (with a subtotal of 30 brands) were\udsubjected to microbiological analysis through conventional culture and biochemical tests. Agar\udwell diffusion method was used to determine the antibacterial trait in the tested samples which\udwas further confirmed by the minimum inhibitory concentration method.\udResults: All samples were found to be populated with bacteria and fungi up to 105 CFU/\udg and 103 CFU/g, respectively. Growth of Staphylococcus spp., Pseudomonas spp. and\udKlebsiella spp. was recorded as well. Conversely, 7 out of 30 items were found to exhibit the\udin vitro antibacterial activity against an array of laboratory test bacterial species including\udStaphylococcus spp., E. coli, Bacillus spp., Pseudomonas spp., Klebsiella spp. and Listeria\udspp. Consequently, all the samples showed antibacterial activity below the concentration of\ud0.46 mg/mL as found in the minimum inhibitory concentration test.\udConclusions: Overall, the presence of huge microbial population in cosmetic products is not\udacceptable from the point microbiological contamination level. The antibacterial trait of these\uditems, in contrary, may draw an overall public health impact
