Is Colgate Total contains cancer-causing chemical Triclosan?
By Anu Passary, Tech Times | August 14, 8:43 AM
A chemical called triclosan, which is used in Colgate Total toothpaste, is said to be linked with cancer cell growth.

The U.S. Food and Drug Administration (FDA) explains that triclosan is included in numerous products to prevent or reduce bacterial contamination. The chemical is also found in furniture, clothing, kitchenware and toys. It is also an ingredient in antibacterial body washes and soaps, toothpastes and a number of cosmetics, which are regulated by the FDA.

The FDA also suggests on its website that triclosan is not hazardous to humans. The FDA reveals that some animal related studies suggest that the chemical changes hormone regulation. However, the government agencies say that certain effects of the chemical in animals do not predict the same effects on humans.

According to Colgate, the Total toothpaste is a trusted name worldwide and thousands of Americans have been using it for many years. Colgate also highlights that the Total toothpaste is also recommended by many dentists.

The toothpaste company explains that the Colgate Total includes 0.3 percent triclosan, which wades off plaque germs harmful for the gums and teeth. The company says that the toothpaste is also clinically-proven to reduce germs better when compared to other toothpastes available in the market.

Colgate also points out that it is not only FDA but also other government agencies across the globe, who suggest that triclosan is safe to use in toothpaste.

"Colgate Total is the only toothpaste on the market that has undergone the U.S. Food and Drug Administration's rigorous New Drug Application (NDA) review process for efficacy and safety, including periodic reviews of scientific literature and safety information. As recently as November 25, 2013, the FDA continues to affirm its support for the use of Colgate Total® toothpaste to fight gum disease," per Colgate.

The toothpaste company also claims that the Colgate Total is the only known toothpaste approved by the FDA and also accepted by the American Dental Association as an effective and safe solution to prevent gingivitis, a gum disease.

Other well-known toothpaste makers such as Procter & Gamble (P&G) and GlaxoSmithKline (GSK) do not use triclosan in their toothpastes. P&G says that the company does not market or produce oral products that contain triclosan. GSK previously used triclosan in some of its toothpastes but the company has reformulated its oral products and they do not contain the purported harmful chemical.

Other report cites that the European Union has placed a ban for the use of triclosan in any food-related products.

It remains unclear if triclosan is harmful to humans; however, it remains to be seen if the FDA starts a fresh investigation to ensure that the chemical is safe to be used in toothpastes.

Should You Keep Using Your Colgate Total Toothpaste?

Colgate Total toothpaste contains an antibacterial ingredient called triclosan. As we recently reported, a Bloomberg News story raised concerns over the potentially harmful effects of the chemical.
While long-term research in humans is lacking, several studies of the effects of triclosan in mice and rats found adverse health effects at high concentrations, including reduced fertility and increased cancer risk. But it's difficult to say if these results would translate into humans, especially because we've been exposed to triclosan in various products for decades. Recent headlines with phrases like "cancer-causing chemical" or "cancer-linked ingredient" are overhyped and fail to account for this.

And while any link with cancer probably sounds scary, it's important to keep in mind that the compound is in the toothpaste for a reason: It helps fight gingivitis, a common disease that causes inflammation and bleeding of the gums.

Do the benefits that triclosan provides in Colgate Total toothpaste outweigh the risks? Or should you throw it in the trash and switch to Crest, which is advertised as 100% triclosan free?

This risk-benefit analysis poses very personal questions, and we can't say for sure if you should switch, but here's what we do know about triclosan.

What is triclosan?
Triclosan is an antimicrobial agent, meaning that it helps to "slow or stop the growth of bacteria, fungi, and mildew," according to the Environmental Protection Agency. It first started to appear in antibacterial hand soap products in the 1970s.

Since then, triclosan has been added to a ton of things — "it has been used in consumer products such as detergents, soaps, skin cleansers, deodorants, lotions, creams, toothpastes, and dishwashing liquids," according to a CDC fact sheet. Many of those products labeled with "antibacterial" potentially contain triclosan or a related compound.

What are the risks?
The truth is, we don't fully know what the risks of triclosan use are. "The human health effects from exposure to low environmental levels of triclosan are unknown ... More research is needed to assess the human health effects of exposure to triclosan," according to a Centers for Disease Control and Prevention fact sheet.

The U.S. Food and Drug Administration, however, has never issued a comprehensive ruling on triclosan's effectiveness and safety — even though it originally said it would look into triclosan in 1974. Now, the FDA says it will issue a ruling on triclosan in 2016.

But because of consumer concerns about safety and environmental impacts, triclosan has been phased out of many soap products because of mounting evidence that these products don't provide health benefits above regular soap and water.

Tests in animals have raised some red flags. For example, one study found that triclosan promoted breast cancer in cells in the lab and in mice. Another study found that exposure to triclosan during fetal development caused neurological damage in some rats.

But it is important to recognize that chemicals can affect animals differently from humans, and animal testing can involve sky-high doses of the chemical in question. However, these kinds of findings in animals mean further testing is warranted before the product is approved for humans.

Direct affects of the chemical on your body are not the only concerns about the additive. In the mid-2000s, environmental groups like the Natural Resources Defense Council, started to raise concerns that the inclusion of triclosan in soaps might be contributing to the rise of antibiotic resistant bacteria, which can cause dangerous infections that are hard to treat. Because soaps get washed down the drain and eventually end up in water systems, the group also found that triclosan could disrupt the algae and wildlife found in water ecosystems. For example, Canadian scientists found that exposure to triclosan caused developmental issues in bullfrogs.

The Environmental Protection Agency website says that triclosan " potentially pos[es] a concern for aquatic organisms." The agency plans to re-evaluate triclosan, but it remains a registered pesticide.

What are the benefits?
According to Colgate's website: "Reviews by the U.S. Food and Drug Administration, the American Dental Association, and government agencies around the world confirm triclosan's safe use in toothpaste and recognize that Colgate Total provides an important health benefit."

The website also says the "safety and effectiveness" of the product is supported by more than 80 scientific studies, involving 19,000 people.

Last year, an independent review of the existing research on triclosan in toothpaste concluded that the chemical "reduced plaque, gingival inflammation, and gingival bleeding" but that those reductions "may or may not be clinically important." Triclosan-containing toothpaste was also associated with a "small reduction" in cavities.

"There do not appear to be any serious safety concerns regarding the use of triclosan ... toothpastes in studies up to three years in duration," the reviewers concluded.

Colgate is quick to point out that real-world evidence seems to echo these results.

"In the nearly 18 years that Colgate Total has been on the market in the U.S., there has been no signal of a safety issue from adverse-event reports," Thomas DiPiazza, a Colgate spokesman, told Bloomberg.

Colgate did not return our request for comment. (We will update this post if we hear back.)

What's the bottom line?
So, should you throw away your tube of Colgate Total? Basically, that's up to you.

If the results of these animal trials scare you, or if you are worried about triclosan seeping into the environment, and you don't have gingivitis, you might want to switch toothpastes. But, the current FDA stance is that "triclosan is not known to be hazardous to humans" and that there is not "sufficient safety evidence" to recommend that consumers stop using products containing triclosan.

Once again it's important to reiterate that often in studies, animals are given very high doses of a chemical relative to the actual levels that humans would consume. So unless you plan on eating a whole tube of Colgate Total (not recommended for other reasons), you will probably be fine. And also, before you switch to a "natural" toothpaste, you might want to know that Tom's of Maine happens to be a subsidiary of Colgate-Palmolive Co.
