"Trichlorin" suspected of being carcinogenic to several brands of toothpaste

According to Voice of China's “News Evening Peak” report, toothpaste can cause carcinogens when it comes to running water? Such a report has recently attracted widespread attention. According to U.S. media reports, because some toothpastes contain a substance called triclosan, encountering chlorine in tap water will produce a carcinogen called chloroform. So, does the toothpaste that is common around us really contain triclosan? Is this thing really carcinogenic? Can toothpaste still be used?

Triclosan is a high-dose antibacterial agent that causes cancer. Reporters found the report on the website of the New York Times. Allegedly, triclosan was suspected to affect the secretion of human hormones and lead to the production of human bacteria. Drug resistance, US Food and Drug Administration and other relevant departments are reassessing the safety of triclosan. And the "New York Times" reported that the famous toothpaste brand Colgate still uses triclosan in its products. What exactly is triclosan?

Kang Jingwu, director of the analysis department of the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences: It is a bacteriostatic agent that can kill bacteria after it is added. Some countries also add gargles and toothpaste. This kind of thing, some experts say is carcinogenic, it is now said that the use of high doses will cause cancer. The lethal dose of triclosan per kilogram of mice is 3,800 mg, and its toxicity may be based on this. From this point of view, it is not too toxic.

With the bactericidal effect of daily chemical products triclosan appeared high rate today (4th) afternoon reporter visited several supermarkets and found that in addition to a Chinese toothpaste, the vast majority of toothpaste ingredients list is not triclosan. In addition, toothpastes such as Colgate, Crest, Chinese, and Black were all sold normally, and there was no case of unsalable or unmarketable toothpaste. Kang Jingwu researcher told reporters that in addition to toothpaste, triclosan is also widely used in shampoo, shower gel, soap, mouthwash and other daily products, especially with a bactericidal effect, the incidence of triclosan is high.

Kang Jingwu: Hand sanitizer and shampoo, I think if it is antibacterial and antibacterial function, Shiyou** has this compound in it. Because it is a very broad-spectrum antibacterial agent, it is also a relatively inexpensive antibacterial agent.

Crest and Chinese toothpaste all stated that they can be assured of their use. In fact, as early as in 2005, American scientists proposed the theory of “trichloran cancer” and caused widespread concern. At the time, experts from the Chinese Center for Disease Control and Prevention told the media that the low dose of triclosan had no effect on the human body to cause cancer.

Last year (2010), the US Food and Drug Administration relaunched the evaluation of triclosan safety. The new study is even more eye-popping. Although triclosan is highly effective and safe, it produces highly toxic dioxins under certain conditions, such as ultraviolet radiation or discharge into the sewer. At the end of last year, some members of the United States even urged the United States to include triclosan on the banned list.

So, does the daily chemical products we use daily have triclosan? Crest toothpaste manufacturer, Procter & Gamble customer service personnel gave the following explanation.

Crest toothpaste manufacturer, Procter & Gamble customer service personnel: Because triclosan is a component, it has been safely and effectively used for more than 30 years in medicine, households, and personal care.

China Toothpaste Manufacturer, Unilever Customer Service: The product (triclosan) content is within the scope of national standards. This can be used with confidence in our company's products.

Oral doctors recommend that you always replace toothpaste brands. Is there a standard for toothpaste ingredients and dosage? The answer is yes. At present, the national standard for toothpaste used in China is a new national standard that has been implemented since February 1, 2009. It states that it is not allowed to add triclosan to raw materials, but it can be used as a preservative in toothpaste, but its content must not exceed 0.3%.

At present, China's relevant departments have not yet tested the toxic effects of triclosan in toothpaste. The reports of foreign experts in the media are equally applicable in the field of daily chemistry, and there is no way for ordinary consumers to judge. In addition, there are many other names for triclosan, such as "Trichlorine," "trichlorin," "Klein," etc. Consumers may not be able to recognize the product formula when they see it. Even if the formula of toothpaste is completely transparent and open, ordinary people cannot know the main effects of various ingredients and what kind of influence they may have on the body.

Beijing Jiahe Dental Clinic doctor told reporters that it is recommended that we often replace toothpaste brand use.

Oral Doctor: The most basic of toothpaste, such as friction agents, foaming agents, and thickening agents, including stereotypes, must be obtained, and certainly, everyone knows. The role played by a small amount of this, including a lot of which may not be what the manufacturer wants it to have, but that comes with the production process, is possible. Do not always use a brand, a product, often change one.
