How does the foam come out of the foaming hand sanitizer facial cleanser, body wash, etc. .

Of course, it is pulled with alkaline ingredients.

It is produced by combining with air.

Surfactants are liquids that are easily touched by gases.

The magic of the foaming hand sanitizer lies in its bottle.

The problem of pressure. Foam generator added.

Hello, this principle is due to the fact that there is a special device at the nozzle of the bottle mouth, which allows the air to be thoroughly mixed with the hand sanitizer. Because the fluid has a depressurizing effect, the middle of the foam gun is an ordinary tip head, and a sleeve with many holes on the side is added to the outside, and when the foaming agent is sprayed from the middle of the sleeve, because the air pressure is reduced, a large amount of air is sucked in from the side, so that foam is produced. Now many places prefer to use foam hand sanitizer, in fact, I personally think that foam hand sanitizer will be easier to write, if it is a general ordinary hand sanitizer, when squeezing out and absorbing, you still need to slowly rub it into a foam, if it is a foam hand sanitizer, it will reduce one step, and it is also more water-saving.

The magic of the foaming hand sanitizer lies in its bottle. The problem of pressure. Foam generator added.

Because of the addition of foaming agent, there is foam.

The foaming agent reduces the interfacial tension at the air-water interface, promotes the formation of small bubbles in the slurry, expands the sorting interface, and ensures that the bubbles rise to form a foam layer.

Introduction to Foaming Agents:

Chinese name: foaming agent.

Appearance: Colorless or light yellow homogeneous liquid.

ph ： 6～8

Foaming capacity: 450ml

Foaming agents are generally surfactants, and their molecular structure is composed of non-polar lipophilic (hydrophobic) groups and polar hydrophilic (oleophobic) groups, forming so-called "amphiphilic" molecules that are both hydrophilic and lipophilic. Lipophilic groups can be aliphatic hydrocarbon groups, alicyclic hydrocarbon groups and aromatic hydrocarbon groups or aliphatic hydrocarbon groups, alicyclic hydrocarbon groups and aromatic hydrocarbon groups with O, N and other atoms; The hydrophilic groups are generally carboxylic acid groups, hydrocarbon groups, sulfonic acid groups, sulfuric acid groups, phosphonic acid groups, amino groups, nitrile groups, thiol groups, halogen groups, ether groups, etc.

The foaming agent is added to the water, and the hydrophilic group is inserted into the water phase and the lipophilic group is inserted into the oil phase or erected in the air to form a directional arrangement on the interface layer or surface, so that the interfacial tension or surface tension is reduced. In general, aqueous solutions containing very small amounts of foaming agents are foaming.

Common foaming agents include hydroxyl compounds, ethers and ether alcohols, pyridines and ketones.

The main thing is to add substances that reduce surface tension, such as sodium stearate and the like, after adding substances that reduce surface tension to the water, in the process of bathing, the liquid continuously inhales air from the air and foams, and the reduction of surface tension makes the foam not easy to break, so the foam is washed more and more, forming a rich foam.

The principle is its chemical composition. Probably sodium stearate. The stearic acid group is a hydrophobic group, and as the name suggests, it is not water-friendly.

However, because this part is an organic part, it can combine with dirty substances such as oil and form a good combination, and then the sodium part is a hydrophilic group, which can be well combined with water. So the oil is connected to the water through this substance, and it washes away. The cause of foaming is the result of the incomplete dissolution of this substance in water after combining with the oil.

That's why foam tends to be dirty too.

Because their main ingredients are surfactants and water. Surfactants encounter water (and other liquids can do) cause the surface tension of the water to decrease, resulting in foam formation. If you remove the water contained in the shampoo, try it, and no matter how much you rub it, it won't lather.

Hand sanitizers are all foamy, foam can be used for deep cleaning**, sterilization.

It is foamy, and it has foam for deep cleaning.

This is the reason for the content in it, and it is washed clean only when there is foam.

Step 1:

Warm water blister hands in autumn and winter, the weather is relatively cold, many people have cold palms, it is best to warm hands with warm water before taking the facial cleanser, because the hand temperature is too low is not conducive to the foaming of the active agent.

Step 2: Add a drop of water to lather the cleanser, especially the paste-like cleanser, which has less water than the lotion cleanser, so you need to add a drop of water to the cleanser, and then start kneading and foaming.

Step 3: Don't crush the palms of your handsWhen rubbing the foam with your hands, don't crush the palms of your palms, and leave a little gap to facilitate air entry and help the cleanser foam. Once the lather begins, continue to gently circular the palm back and forth for 10-20 seconds, prompting more rich, delicate lather.

Step 4: When you put the foam in your palm over your face and feel that the cleanser is fully foaming, cover the foam on your hands on your face, gently rub your forehead, nose, chin, corners of your mouth, cheeks and other parts, and rub each part for at least 20 seconds, which can promote the foam of the cleanser to more fully dissolve the sebum and make your face cleaner.

Step 5: Rinse off the facial cleanser foam on your face with warm water After washing your face, you should use warm water to wash off the remaining foam on your face, as dirt residues will clog pores and cause new problems.

You can buy a frother to squeeze the facial cleanser and add a little water to have a dense bubble.

Some facial cleansers don't foam, so you have to buy the kind of foam type, and there are the kind of things that are specially foamed, like bath bombs, and simply rubbing them by hand will not have that effect.
