3,4,4'-Trichlorocarbanilide (TCC) is primarily used as an antimicrobial agent in personal care and consumer products. It is commonly added to soaps, hand washes, body washes, deodorants, cosmetics, and toothpaste for its ability to kill or inhibit the growth of bacteria, helping to reduce the risk of infections and prevent microbial contamination. TCC is also incorporated into household cleaning products, such as floor cleaners and laundry detergents, to enhance germ-killing efficacy. In the textile industry, it is applied to fabrics to create antimicrobial finishes, making them resistant to odor-causing bacteria in clothes and sports equipment. Additionally, TCC is used in medical settings for disinfecting surfaces and equipment. Its broad-spectrum antimicrobial properties make it a versatile ingredient in various applications aimed at promoting hygiene and preventing the spread of pathogens. However, its use should be controlled to minimize environmental and health impacts.
