The Confusion Of The Public: Shampoo Can Cause Cancer?

In July 14, 2010,

This is the 16 time in two months that the two oxane has "stirred up trouble".

In March 12, 2009, the United States "safety cosmetics campaign" released a report that it was sent to 48 independent laboratories in California.

After two times of two oxane incidents, the relevant quality supervision and management departments of the state responded.

AQSIQ has sampled Johnson bathing products made by China (China) Limited. Its dioxane content is at a relatively low dose level, and it will not cause harm to the human body.

After the disclosure of the "two oxane incident" of the king shampoo, the State Food and Drug Administration attaches great importance to the food and drug administration. The food and Drug Administration of Guangdong immediately asked the relevant products of the company to carry out spot checks. The results showed that the level of two oxane in the sample was not harmful to the health of consumers.

From Johnson bathroom products to Bawang shampoo, relevant manufacturers have stated that trace two oxane in products is due to the fact that prohibited substances can not be prohibited from being imported into the product technically, and that they are not required for raw material formulation.

The existence of this two oxane determines the existence of two oxane in sanitary and shampoo products. If screening is carried out, there will be products with the same dose level of two oxane, not limited to Johnson and Overlord products.

Because unsolved problems are the common problems faced by all enterprises in the field.

There is no absolute poison in real life and there is no absolutely harmless substance.

Harmful and harmless depend to a large extent on contact dose, contact time and contact mode.

As early as the late 70s of last century, FDA began to monitor the content of two oxane in cosmetics.

From 1992 to 1997, the US FDA monitored that the content of two oxane in some cosmetics was 79ppm, but FDA did not think that this level would harm consumers' health.

The acute toxicity test of two oxane belongs to the category of micro toxicity.

Oral intake of two oxane was observed in rats. The lethal dose of half experimental animals was 5170mg/kg. The lethal dose of half of the experimental animals in rabbits was 7600mg/kg. Inhalation of respiratory tract for 2 hours in rats, the lethal dose of half experimental animals was 46000mg/m3.

It has been reported that two oxane has the possibility of carcinogenesis in laboratory animals, and the tumor is positive in mice exposed to 1440mg/kg (60 weeks, intermittent).

Comparatively speaking, the content of two oxane in sanitary and shampoo products is very low.

The official website of the Australian health administration website estimates technical documents and recommended standards for two oxane. It considers that except for food and drugs, the ideal limit of two oxane is 30ppm in daily consumer goods, and the content is not more than 100ppm, which is acceptable in toxicology.

Modern medical research can judge the toxicological characteristics of a single substance, and guide and regulate people's production and consumption behavior.

When people are exposed to various chemicals at the same time, the effect of additive, subtractive or multiplying in the toxic expression category of chemicals is difficult to solve in the world.

A shampoo product has been reported to contain dozens of chemicals or even more.

Generally, shampoo contains surfactants, conditioners, moisturizers, moisturizers, emulsifiers, viscosity modifiers and so on. However, there are several kinds of substances in each category, and the products are regarded as commercial secrets.

In view of this, the National Standard Commission promulgated the "general label for cosmetics used in consumer goods," which requires all cosmetics to be identified after October 1, 2009.

State related policies, regulations and technical specifications are usually rough.

If only the "whitening import factor", "natural plant extract", "vitamin nourishing formula" or "English labeling" are used in the market, most consumers will still be "blurred" and can not understand the true colors of Mount Lu.

To comply with the state's policies and regulations, in order to safeguard the legitimate rights and interests of consumers, the manufacturers concerned have the responsibility to clearly mark the names of the main components in Chinese.

It is technically impossible to label all ingredients.

For example, two oxane really comes from upstream raw materials, not Johnson and Overlord company's initiative to add. If there is no technical terms to restrict it, such substances are theoretically infinite, because all substances existing in natural environment are likely to be found in any product or even human body, but the dose is different.

As a clinician, I have not seen patients who use shampoo to cause poisoning or cancer so far.

In the field of clinical medicine, or in people's daily life, there is actually a problem of following different health "protection degrees".

If patients with the same disease have different medical treatment behavior, psychological burden and medical expenditure, there are significant differences.

Consumers who use sanitary and shampoo products once they know that the products they use contain two oxane, although the relevant departments of the state have made no health consequences, but for consumers, it will inevitably lead to different consumer behavior choices and psychological burden.

Relevant research has confirmed that the sale of sanitary bathrooms and shampoo products approved by the quality management department has a basic guarantee for people's health and consumers can rest assured.

However, safety and health are always relative concepts.

In the endless stream of bathroom and shampoo products, any product has gathered a lot of ingredients. Only focusing on two oxane can not solve all problems.

According to domestic research reports, 3 different brands of commercially available shampoo were used to observe the genotoxic effect of Vicia faba root tip cells. The results showed that 3 types of shampoo mutated the root tip cells of Vicia faba, resulting in a variety of chromosomal aberrations, indicating that the tested shampoo had genotoxic effects on root tip cells of Vicia faba.

Vicia faba root tip cells are not equal to human body.

Media reporters asked me how consumers use shampoo, hair conditioner, unwashed or unwashed, and I don't think any difference in current clinical symptoms can be seen.

If you read the report about the genotoxicity of shampoo to the root tip cells of Vicia faba, which is the integration effect of many substances, and care about it, it is better to rinse shampoo and conditioner after bathing.
