Triclosan is widely used as an antimicrobial agent in personal care and consumer products. It is commonly added to toothpaste, soaps, and deodorants for its ability to reduce or prevent bacterial contamination. In toothpaste, it helps control plaque and gingivitis. It is also found in mouthwashes for its antibacterial properties targeting oral pathogens.

In addition, triclosan is incorporated into textiles, plastics, and kitchenware to inhibit bacterial growth on surfaces. It has been used in healthcare settings in surgical scrubs and hand sanitizers to reduce microbial load. However, due to concerns over antibiotic resistance and environmental impact, its use has been restricted in some products and regions.
