Shouldn t toothpaste contain bleach?

It does not contain bleach, and if it is a whitening toothpaste, there are two factors for the whitening effect, one is because the friction agent plays the role of physical removal of pigment, and the other factor is that the chemical active ingredient plays the role of chemical and physical removal of pigment.

Sodium hexamineric phosphate.

It can effectively inhibit the formation of tartar and inhibit the adsorption of new color sources on the tooth surface for a long time, which has also recently been introduced as a whitening toothpaste to help remove exogenous staining from the tooth surface. Sodium hexamerobyaphosphate contains 10 12 repeating pyrophosphate subunits, which gives it a stronger adsorption of hydroxyapatite. Sodium hexaminylphosphate adsorbs acquired membrane proteins, removing exogenous pigments and inhibiting the adsorption of new chromogens by changing the composition of the salivary acquisition membrane.

Sodium tripolyphosphate.

Sodium phosphate, a linear condensation of sodium phosphate, is commonly used in whitening toothpaste, which can effectively remove exogenous staining on the tooth surface. The mechanism of sodium tripolyphosphate inhibiting the pigmentation of the tooth surface and clearing the tooth staining may be that sodium tripolyphosphate has more anions competing with the pigment and protein for the binding site and adsorbing on the surface, thereby inhibiting the attachment of the pigment and protein and promoting its desorption. In addition, sodium tripolyphosphate can chelate calcium ions, which are important factors for anions such as proteins, theabrownin, and polyphenols to attach to the surface of hydroxyapatite and maintain it on the obtained membrane.

If the whitening toothpaste does not contain bleach, it will still whiten a fart, so it is better to go home and dip it in some salt and brush it! The so-called dosage is to talk about toxicity is to play hooligan, the average mass fraction of phosphite in whitening toothpaste is about 5%, and the dosage of toothpaste is only a few grams each time. So the dosage is still very important, and you must look at the dosage.

I would like to say that although a small amount of bleach in toothpaste will not kill us, because this kind of substance has a certain toxicity, if the amount of use and the amount of residue cannot be strictly controlled, it will definitely cause potential harm to human health.

Each brand of toothpaste has a different amount of drops in it. If it's not good-looking, my teeth will have to be booked for nothing, but some of the plant-based toothpaste will not have it.

1. Fluoride toothpaste: It is a toothpaste that adds an appropriate amount of fluoride to the toothpaste and has the function of preventing tooth decay. Numerous studies have proven that fluoride can improve the resistance of teeth to corrosion and inhibit the growth and reproduction of cariogenic bacteria.

Fluoride is also present in the normal oral environment, but its concentration is not sufficient to cause these changes. The use of fluoride toothpaste is to increase the fluoride in the oral cavity within a safe range to form a strong protective layer on the tooth surface, thereby reducing the occurrence of tooth decay.

Reminder: Children under 3 years of age should avoid fluoride toothpaste due to the presence of toothpaste swallowing in children; Children aged 4-6 years old should use it under the guidance of adults, and the amount of each brushing should be the size of a soybean grain.

2. Chinese herbal toothpaste: It is a drug that adds some Chinese herbs on the basis of ordinary toothpaste, which has the effects of clearing heat and detoxifying, reducing inflammation and stopping bleeding, which can have a certain auxiliary effect on alleviating the inflammation of the gums.

3. Anti-inflammatory toothpaste: On the basis of ordinary toothpaste, certain antibacterial drugs are added to reduce inflammation and antibacterial, inhibit the formation of dental calculus and plaque, and play a role in improving the oral environment, preventing and assisting gingival bleeding and periodontal disease.

4. Allergy-free toothpaste: This toothpaste contains desensitizing ingredients such as potassium nitrate or strontium chloride, which has a certain alleviating effect on the allergy of Yashan.

5. Descaling and whitening toothpaste: This kind of toothpaste contains drugs such as peroxide or hydroxyapatite, which uses the principle of friction and chemical bleaching to remove the coloration of the tooth surface and play a role in whitening the teeth.

There is a fe Jindian dentist, biological enzyme toothpaste, the application of biological enzymes taught in our high school textbooks, sterilization and then anti-cavity without fluoride, and then the supermarket saw it and bought it, and now we use it all in our family, **It doesn't matter if it's a little higher, the key is safety, and now the cheap ones don't dare to use. The price is so high, how can it be done if it is not miserable.

Recently, it was found that six brands of whitening toothpaste, including Chungwa, Colgate, Heimei, Crest, Black and Liby, contained bleaching substances, which damage the enamel layer of teeth and were irreversible in many cases.

Personal suggestion, recommend the old brand of cold acid ling,

If you don't buy whitening effect, it's not bad to change the moth-proof. Isn't rice poisonous to be eaten every day?

This time, the toothpaste contains bleach, which is the conclusion reached by a Guangxi family through experiments. They purchased six brands of whitening toothpaste, including Zhonghua, Colgate, Heimei, Crest, Heiren, and Liby, for testing, and the results showed that all six kinds of toothpaste could fade with a test agent prepared with iodine solution, dilute sulfuric acid and starch, and it was concluded that the toothpaste contained more or less bleach, and it was inferred that the bleaching substance was a sulfite or similar substance.

And another ** used the same method to experiment with the drink and found that it also faded, does the drink also have bleach? Don't believe it, it's okay.

Use the brand you're used to...

Can mixing toothpaste and bleach produce toxic gas?

Answer: The composition of bleach is CaCl2 and Ca(ClO)2, and pure hydrolysis will produce HCOs. Toothpaste is weakly alkaline, and the main ingredient is calcium carbonate.

The two undergo a chemical reaction to produce carbon dioxide. Innocuity.

When you brush your teeth, you don't use toothpaste, you use baking soda that you use when you cook, and brush your teeth with some dipping, which is much whiter than toothpaste.

Personally, I think Yunnan Baiyao toothpaste is still good and has been using it. It's just a little more expensive.

I'm afraid of this, I'm afraid of that, I'm going to die, I'm going to die...

In May 2013, a ** company in Guangxi purchased six brands of whitening toothpaste, including Zhonghua, Colgate, and Heimei, and submitted them to a professional testing agency for testing, and found that the above brands of whitening toothpaste contained more or less bleaching ingredients, and inferred that this bleaching substance was a sulfite or similar substance. In a statement dated May 3, 2013, the China Oral Cleaning and Care Products Industry Association questioned this test method, pointing out that iodine solution, dilute sulfuric acid and starch were used as test agents to test the composition of whitening toothpaste, and there was great uncertainty in scientific principles, and many factors and substances could change the color of the solution.

According to the association, there is a discrepancy between the reported problem of sulfites in whitening toothpaste.
