영문 초록

Most of cosmetics are emulsion products that contain the source of nutrition vegetable oil, mineral oil, natural extract and carbohydrate etc. There are many possibilities to be contaminated by microbials. We investigated the effect of antimicrobial and minimum inhibitory concentration(MIC) with thiamine dilauryl sulfate(TDS), which was prepared to use cosmetic lotion formulation. Staphylococcus aureus(S. aureus) and Escherichia col(E. coli) were used as test organism. MIC value of TDS was determined aganist microorganism for the growth inhibition by concentration of TDS. From the MIC results, antimicrobial effect of TDS was generally more effective to gram positive than gram negative. Antimicrobial effect with pH value against some microorganism appeared in the following order : pH 5 > pH 6 > pH 7. It showed strong antimicrobial activities against S. aureus, and weak antimicrobial activities against E. coli. If it was possible to determine the formulations with TDS, it would be effective to reduce the artificial preservatives.
