Triclosan is an antibacterial and antifungal agent found in many consumer products, including soaps, detergents, and toothpastes. In hospitals, it is used in surgical scrubs, hand washes, and sutures. While it is effective in reducing the risk of surgical site infections, its use in antibacterial soaps has come under scrutiny in recent years. Studies have shown that washing with antibacterial soaps containing triclosan is not significantly more effective than using plain soap and water in preventing illness. Due to these findings and concerns about the potential health and environmental impacts of triclosan, the U.S. Food and Drug Administration (FDA) banned the sale of consumer antiseptic wash products containing triclosan in 2016. However, this ban does not apply to antibacterial soaps used in healthcare settings, such as hospitals.

What You'll Learn
Triclosan's effectiveness as an antibacterial agent in hospitals
Triclosan is a chemical ingredient with antibacterial and antifungal properties. It was first used as a pesticide in the 1960s and has since been added to a wide range of consumer goods, including soaps, detergents, cosmetics, and surgical cleaning treatments.
In hospitals, triclosan is used in surgical scrubs, hand washes, and antiseptics. It is also integrated into the surfaces of medical devices, such as surgical sutures. The use of triclosan in surgical units is considered effective with a minimum contact time of approximately two minutes.
The effectiveness of triclosan as an antibacterial agent has been called into question in recent years. In 2013, the U.S. Food and Drug Administration (FDA) asked the makers of antibacterial soaps and body washes containing triclosan to provide data proving their safety and effectiveness in preventing infections compared to regular soap and water. The FDA concluded that these products had not been proven to be any more effective than plain soap and water and, therefore, banned their sale in 2016.
However, some studies suggest that antimicrobial hand soaps containing triclosan may provide slightly greater bacterial reduction on the hands than plain soap. Additionally, triclosan-coated sutures have been found to reduce the risk of surgical site infections.
While triclosan has been shown to be effective in certain applications, concerns have been raised about its widespread use and the potential development of antibiotic resistance. Some studies have also linked triclosan exposure to an increased risk of food allergies and allergic contact dermatitis. Overall, while triclosan may have some benefits in hospitals, its effectiveness as an antibacterial agent is still a subject of ongoing research and debate.

Potential health risks of triclosan exposure for healthcare workers
Triclosan is a chemical ingredient with antibacterial and antifungal properties. It was first used as a pesticide in the 1960s and has since been added to various products, including antibacterial soaps. In hospitals, triclosan is used in surgical scrubs, hand washes, and sutures. While triclosan can effectively reduce the risk of surgical site infections, its widespread use has raised concerns about potential health risks for healthcare workers.
Healthcare workers are exposed to triclosan through occupational sources such as triclosan-containing soaps and personal care products. Studies have found that working in hospitals that use triclosan products is associated with higher levels of triclosan in the body. The potential health risks of triclosan exposure for healthcare workers include:
- Endocrine disruption: Triclosan is a potential endocrine disruptor, and in vivo and in vitro studies have shown endocrine-disrupting effects in mice. However, the effects of triclosan exposure on endocrine function in humans require further investigation.
- Allergic reactions: Triclosan has been linked to allergic contact dermatitis and allergic sensitization, particularly to inhalant and seasonal allergens.
- Bacterial resistance: Long-term exposure to triclosan may contribute to the development of drug-resistant bacteria, making it harder to treat common bacterial infections.
- Hormonal effects: The widespread use of triclosan may impact hormonal development, although the mechanism behind this effect is still controversial.
- Environmental toxicity: Triclosan can contaminate water sources and is toxic to aquatic animals.
- Food allergy: Some studies suggest that triclosan exposure may be associated with a higher risk of food allergies, although this may be due to reduced exposure to bacteria rather than the toxicology of triclosan itself.
While the use of triclosan in hospitals may provide benefits in terms of infection control, the potential health risks for healthcare workers should be carefully considered. Further research and larger-scale studies are needed to fully understand the long-term effects of triclosan exposure in humans.

The FDA's stance on triclosan in antibacterial soap
In 2013, the FDA asked the makers of antibacterial soaps and body washes to provide data proving that these products were safe and effective in the long term, and that they were better at preventing infections than regular soaps.
In 2016, the FDA issued a final ruling that companies could no longer sell antibacterial soaps and other products containing triclosan in the United States. The FDA stated that these products may not be safe and that they are no more effective than regular soap and water. The FDA also stated that there was no evidence that antibacterial soaps with triclosan do a better job of cleaning hands, and that the chemicals in them may pose health hazards.
The FDA ban applies only to consumer products, not those used in hospitals and food service settings. The FDA's rule also does not affect hand sanitizers or antibacterial wipes.
The FDA has deferred rulemaking for one year on three additional ingredients used in consumer wash products: benzalkonium chloride, benzethonium chloride, and chloroxylenol (PCMX). During this time, consumer antibacterial washes containing these ingredients may be marketed while data is being collected.
The FDA has also confirmed that there is extensive evidence showing that triclosan in Colgate Total toothpaste prevents gum disease.

Bacterial resistance to antibiotics due to triclosan
Triclosan is a chemical ingredient with antibacterial properties. It is an organic compound that is soluble in ethanol, methanol, diethyl ether, and strongly basic solutions. It was first used as a pesticide in the 1960s and has since been added to many consumer products, including soaps, detergents, toys, surgical cleaning treatments, and body washes.
In recent years, concerns have been raised about the potential impact of triclosan on bacterial resistance to antibiotics. While triclosan is effective at killing bacteria, its widespread use may contribute to the development of antibiotic-resistant bacteria. This is because triclosan does not kill 100% of bacteria, and the bacteria that survive may develop mutations that make them more resistant to antibiotics.
A study conducted in 2019 found that bacteria exposed to triclosan were significantly more likely to survive treatment with antibiotics compared to bacteria that were not exposed to triclosan. This suggests that the use of triclosan may contribute to the development of antibiotic-resistant bacteria.
In response to these concerns, the U.S. Food and Drug Administration (FDA) banned the sale of consumer antiseptic wash products containing triclosan in 2016. The FDA stated that these products may not be safe and are no more effective than regular soap and water. However, triclosan is still allowed in other consumer products, such as toothpaste, where it has been shown to be effective in preventing gum disease.
The impact of triclosan on bacterial resistance to antibiotics is a complex issue that requires further research. While it is important to prevent the spread of bacteria and infections, it is also crucial to consider the potential long-term effects of triclosan use on bacterial resistance and explore alternative methods for preventing the spread of bacteria.

Alternatives to triclosan in antibacterial soaps
In 2016, the U.S. Food and Drug Administration (FDA) banned the sale of consumer antiseptic wash products containing triclosan. This was due to concerns about its impact on bacterial resistance to antibiotics, environmental toxicity, and ill health effects. The ban came into full effect in 2020, and as a result, companies have begun to replace triclosan with alternative ingredients.
Some common alternatives to triclosan in antibacterial soaps include benzalkonium chloride, benzethonium chloride, chloroxylenol, and chlorhexidine. These alternatives are antimicrobial agents that are intended to kill bacteria. However, it is important to note that some of these alternatives may be more toxic than triclosan and can cause allergic and irritant contact dermatitis.
Alcohol, specifically ethyl alcohol and isopropyl alcohol, has become the major germ-killer in hand sanitizers since the removal of triclosan. Alcohol-based hand sanitizers are recommended by the FDA and other experts when soap and water are not available. These sanitizers should contain at least 60% ethyl alcohol or 70% isopropyl alcohol to be effective.
Natural and nature-inspired antibacterial ingredients are also being used as alternatives to triclosan. For example, Unilever, a major manufacturer, has replaced triclosan and triclocarban in their soaps, toothpastes, hand washes, and bath liquids with natural alternatives.
It is important to note that the safety and effectiveness of these alternatives are still being evaluated, and some experts argue that the best alternative to antibacterial soaps is simply using plain soap and water.
