Titanium dioxide is classified as a class 2B carcinogen. Can the sunscreen still be used?

Titanium dioxide (TiO), an "excellent molecule" found in sunscreen products, has recently been labeled as a Class 2B carcinogen by the European Union.

How did a good sunscreen become a carcinogen? can you still use the sunscreen in your hand?

According to the risk of carcinogenesis to humans, IARC classifies chemicals that are at risk of causing cancer to humans into four categories.

Category 1: carcinogenic to human beings, with definite carcinogenicity.

Class 2A: carcinogenic to humans, there is sufficient evidence to prove carcinogenicity to laboratory animals but limited evidence to human carcinogenicity.

Class 2B: it may cause cancer to humans, there is no sufficient evidence to prove that it is carcinogenic to laboratory animals, and the evidence of carcinogenicity to humans is insufficient.

Category 3: it is impossible to classify the carcinogenicity of human beings, and the possibility of carcinogenicity to human beings is low.

Category 4: it is very likely not to cause cancer to people.

If you make a percentile classification of four types of carcinogens, category 1 is 100%, and category 2B is about 50%.

Why is titanium dioxide famous on the "list"?

Titanium dioxide is widely used as a white pigment, which can reflect and scatter light, and is often used in coatings, plastics, cosmetics and other fields.

It is usually added to sunscreen products as a physical sunscreen.

Class 2B carcinogens originated in a French study that found that exposure to high levels of titanium dioxide in rats led to lung cancer.

Therefore, it is speculated that inhalation of titanium dioxide may also cause the same harm to the human body, and the list of carcinogens is a reminder to consumers of possible risks.

Does the sunscreen in your hand still work?

We mentioned earlier that titanium dioxide is listed as a carcinogen based on an animal experiment, which mainly demonstrates the effects of titanium dioxide in the form of respirable particles on the body. and cancerous reactions only occur when exposed to high concentrations of titanium dioxide for a long time.

In other words, if you are using smeared sunscreen, you don't have to worry about it. The sunscreen we use usually has a low content of titanium dioxide.

Does the sunscreen spray still work?

Like smeared sunscreen, titanium dioxide is often added to sunscreen spray only as an ingredient, which is not enough to pose a cancer risk in terms of concentration and dose.

Unless.

Do you have any special habit of spraying sunscreen spray into your nose every day?

Of course, we do not recommend that people spray into their own respiratory tract when using sunscreen spray, and try to use smear sunscreen products for facial sunscreen.

Beside the point, tobacco and alcohol are classified as category 1 carcinogens, but it does not hinder their normal circulation in the market. As long as the dose is sufficient, everything can be toxic.

Daily sunscreen or do a good sunscreen, and so on for fear of being "poisoned" by the sun, then really want to cry without tears.
