Triclosan
An antibacterial and antifungal agent used in various consumer products
Overview[edit | edit source]
Triclosan is a synthetic antibacterial and antifungal agent that is commonly found in a variety of consumer products, including soaps, detergents, toothpaste, and cosmetics. It is used to reduce or prevent bacterial contamination.
Chemical Properties[edit | edit source]
Triclosan is a chlorinated aromatic compound with the chemical formula C12H7Cl3O2. It is a white powdered solid with a slight aromatic, phenolic odor. The compound is only slightly soluble in water but is soluble in most organic solvents.
Mechanism of Action[edit | edit source]
Triclosan works by inhibiting the enzyme enoyl-acyl carrier protein reductase, which is involved in the synthesis of fatty acids in bacteria. This inhibition disrupts the bacterial cell membrane, leading to cell death. Triclosan is effective against a wide range of gram-positive and gram-negative bacteria.
Uses[edit | edit source]
Triclosan is incorporated into a variety of products for its antimicrobial properties. These include:
- Personal care products such as antibacterial soap, toothpaste, and deodorants.
- Household items like kitchenware, furniture, and toys.
- Medical devices and surgical equipment to prevent bacterial contamination.
Health and Environmental Concerns[edit | edit source]
There has been growing concern about the potential health and environmental impacts of triclosan. Studies have suggested that triclosan may contribute to the development of antibiotic resistance and may have endocrine-disrupting effects. Additionally, triclosan can persist in the environment, leading to potential ecological impacts.
Regulation[edit | edit source]
Due to these concerns, regulatory agencies in several countries have taken steps to limit the use of triclosan. For example, the United States Food and Drug Administration (FDA) banned the use of triclosan in over-the-counter antibacterial soaps in 2016, citing insufficient evidence of its safety and effectiveness.
