Triclocarban is a triclosan analogue with an antibmicrobial property. It has been used in a wide range of personal cleansing products including deodorant and bar soaps, deodorants, detergents, cleansing lotions, and wipes. In US triclocarban was approved for marketing of over-the-counter (OTC) consumer antiseptic wash products. But on September 2, 2016 U.S. Food and Drug Administration banned containing triclocarban and triclosan consumer antiseptic wash products from further marketing in USA because of a potential damage to human health, resulting from extended exposure to antiseptic active ingredients on a regular bases. However the new rule does not not affect consumer hand “sanitizers” or wipes, or antibacterial products used in health care settings. Triclocarban is a limited spectrum antibacterial agent effective in vitro against some strains of staphylococcus, streptococcus, and enterococcus bacteria. The minimum inhibitory concentration has been found to range from 0.5 to 8 mg/L for these various strains. Triclocarban can act by non-specific membrane-destabilizing mechanism; also was suggested, that similar to triclosan, Triclocarban exerts its effect by inhibiting the activity of enoyl-(acyl-carrier protein) (ACP) reductase, widely distributed in bacteria, fungi and plants. As a result, this agent interrupts cell membrane synthesis and leads to bacterial growth inhibition.   ^NCATS
