Why does the toothpaste separate from the toothpaste when it encounters water?

Toothpaste is hydrophilic, unlike oil, toothpaste will attract water when it encounters water. I don't know if you have noticed this interesting phenomenon when people are brushing their teeth. If there is a small amount of water on the ground, some of the water around the toothpaste will disappear when the toothpaste falls to the ground.

Also, if the toothpaste foam we produce when we brush our teeth falls to the floor, this interesting phenomenon can also occur. What's going on? So we did a little experiment:

A drop of water is dropped onto a dry and clean porcelain plate (glass plate is also acceptable), and then squeeze some toothpaste onto the porcelain plate, the same as before.

As soon as the drop of water came into contact, the water disappeared instantly. So, we figured out that it was the toothpaste that sucked the water away. But how does it do it?

So we went one step further and investigated and collected evidence. Finally, we finally got to the bottom of the matter. It turns out that the reason why toothpaste absorbs water is because there are some substances used to make adhesives in toothpaste, and the role of this adhesive in toothpaste is to stabilize the paste and avoid water volatilization, it forms a viscous liquid by diffusion and water absorption, so that the solid and liquid of toothpaste remain homogeneous.

At present, the commonly used adhesive is sodium carboxymethylcellulose.

Magnesium aluminosilicate composite colloid. These substances are generally in excess, so in addition to acting as an adhesive in toothpaste, they can absorb more water, and they don't get dirt when brushing.

or something else, and it won't deteriorate. Therefore, both toothpaste and toothpaste foam have the ability to absorb water. Moreover, when the toothpaste becomes toothpaste foam, because of the surface area of the toothpaste foam.

Toothpaste has an adhesive that absorbs water.

Summary. Why does pro 3 toothpaste get into water? This is because the characteristics of toothpaste are determined, toothpaste is an active material, its microstructure is small, larger than the void, has a relatively large porosity, so that the gas and water vapor in the toothpaste penetrate easily, and the water may penetrate into the toothpaste from the outside, making the toothpaste collapse, and the situation of water entering the situation is pro 3.

In addition, there is also a possibility that the toothpaste contains active substances such as soap, which makes the toothpaste highly absorbent and more susceptible to water attack, making the toothpaste become thick and paste, and water will enter. In addition, improper use may also cause water ingress into the toothpaste, such as putting the toothpaste in a moist container, not only the toothpaste cannot maintain the original texture, but also easily absorbs water and becomes puree, resulting in water ingress. Therefore, in order to prevent the toothpaste from getting water, you need to avoid the effects of moisture and try to absorb excess water before use.

In addition, there is also a possibility that the toothpaste contains active substances such as soap, which makes the toothpaste highly absorbent and more susceptible to water attack, making the toothpaste become thick and paste, and water will enter.

In addition, improper use may also cause water ingress into the toothpaste, for example, if the toothpaste is packed in a container with pure moisture, not only can the toothpaste not maintain its original texture, but also it is easy to absorb water and become puree. Therefore, in order to prevent the toothpaste from getting water, you need to avoid the effects of moisture and try to absorb excess water before use.

Toothpaste dipped in water is a big misunderstanding, and they all think that it is easy to slide in the mouth after dipping in water, and it is very brisk, but in fact, it is completely unnecessary. Toothpaste is directly put into the mouth, due to its own viscosity, the impurities in the mouth can be wrapped in it, and the human mouth itself has saliva, which will naturally soften and dilute the toothpaste, but people are used to dipping it in water.

Should toothpaste be wet before use? It depends on personal habits, I usually don't get wet, but I will rinse a mouthful of water first, relatively speaking, it should be considered water, and if the water is wet, the bubbles will feel smoother when you use it.

Yes, dip a little, and the toothpaste will not foam.

When we get up every morning, the first thing we have to prepare is to brush our teeth, but in the process of brushing our teeth, many people have misunderstandings about the steps of brushing our teeth, for example, before brushing our teeth, we should dip the toothpaste in water, but in fact, this is not the case, so many people have doubts about the correct steps of brushing their teeth, so the problem comesHow much do you know about the common sense of wrong life, should you get wetted before using toothpaste? The answer, of course, is no. In daily life, we all know that toothpaste will produce more foam after being wet, many people think that the more foam, the better it is for teeth, but in fact, it is not, the more foam, the more likely it is not to play the role of cleaning, the reason why toothpaste can do the role of cleaning teeth, mainly depends on some small particles in the toothpaste, which play a role of friction between the teeth, so as to achieve the purpose of cleaning the teeth, and if the toothpaste is stained with water, the foam will be more, This will easily lead to less small particles in the toothpaste, and the cleaning effect will be greatly reduced, so people do not need to moisten the toothpaste when brushing their teeth.

And people in the process of brushing teeth, need to pay attention to some precautions, such as the way of brushing teeth, when brushing teeth, do not brush horizontally, which is not good for teeth, secondly, the brushing time should not be too short, otherwise for the teeth, it will not play a role in cleaning, and there is, in the eyes of the guests is a more important point, that is, when choosing a toothbrush, you should choose the right one, and the effect is better, the most important point is not to stain the toothpaste with water before brushing your teeth.

If the toothbrush is too large, not only is the effect not very good for brushing, but it may also cause damage to the mouth, so when people choose a toothbrush, they should choose the right one for themselvesHowever, the most important thing in brushing your teeth is not to wet the toothpaste before brushing your teeth, otherwise the cleaning effect will not be good.

Yes. Toothpaste can be moistened with water to create a lot of foam, which can lubricate the friction between the teeth and the toothbrush, reduce gum damage, and also better clean the teeth.

Don't, why, first of all, you have to know that you should brush your teeth for at least three minutes, when you brush the foam for a minute after you dip in water, the foam will come out, the mouth is full of foam, you just want to drink water and rinse your mouth, and you haven't brushed it in place at all, or you don't get wet and slowly brush out the foam, and your teeth will be brushed more in place.

The first point is that the toothpaste should not be dipped in water before use, so that the dirt in the teeth can be brushed clean, and the second point is that if you are wet, the foam is very rich, and it may not achieve the desired effect.

Guidance:

There are some substances used as adhesives in toothpaste, this adhesive plays a role in toothpaste to stabilize the paste and avoid water volatilization, it forms a viscous liquid through diffusion expansion and water absorption, so that the solid and liquid of toothpaste remain homogeneous. At present, the commonly used adhesive is carboxymethyl cellulose sodium, magnesium aluminosilicate composite colloid. These substances are generally in excess, so in addition to acting as an adhesive in toothpaste, they can also absorb more water.
