CAS No. 17940-81-7 is a white solid organic compound, commonly known as triclosan. It is an antimicrobial agent used in many consumer products, including toothpaste, soaps, shampoo, and deodorants. It is also used in a variety of medical applications, such as antiseptics and disinfectants.

Triclosan was first synthesized in 1964 by researchers at the Swiss company Ciba-Geigy. It is a chlorinated aromatic compound, composed of a phenyl ring and three chloro substituents. It is a highly lipophilic molecule, allowing it to easily pass through cell membranes, and has a broad spectrum of antibacterial activity.

Triclosan has been used for decades as an effective antimicrobial agent in a variety of consumer and medical products. Its broad spectrum of activity makes it effective against a wide range of microorganisms, including bacteria, fungi, and viruses. It is also effective against a number of antibiotic-resistant microorganisms.

In addition to its antimicrobial properties, triclosan has been shown to be an effective anti-inflammatory agent, and has been used to treat a variety of skin conditions. It has also been found to be effective in reducing the growth of biofilms, which can cause many infections.

Triclosan is generally regarded as safe when used as directed, but there have been concerns about its potential health effects. It has been found to accumulate in some tissues, and has been linked to endocrine disruption and cancer in animal studies. The European Union has banned its use in household products, and the US Food and Drug Administration is considering a ban.

Despite these concerns, triclosan remains an important antimicrobial agent, and is widely used in a variety of consumer and medical products. Its broad spectrum of activity makes it an effective agent against a variety of microorganisms, and its anti-inflammatory properties make it useful for treating a range of skin conditions.
