What surfactant do you use for that shampoo?

Traditional shampoos always contain a variety of surfactants, including soap.


Surfactants are substances that act on the boundary surface (interface) between two different substances to facilitate mixing.

Surfactants have both a hydrophilic group that is easily compatible with water and a hydrophobic group (lipophilic group) that is easily compatible with oil in one molecule.


In addition, surfactants have the function of lowering the surface tension of water, making it easier for water to soak into things.

Due to the above properties, the surfactant plays a role of removing stains on the skin and hair.


When choosing a shampoo, what kind of surfactant is used is important.


A certain amount of detergency is required to wash away sebum and dirt, but if the detergency of a surfactant is strong, it may degrease more than necessary, which may cause irritation to the skin or make the hair dry I will.

On the other hand, if you use a product with a weak detergency, it will not be able to remove enough sebum and dirt from dogs that produce a lot of sebum or are very dirty.


When choosing a shampoo, it is important to first identify the type of surfactant.
By doing so, you will be able to find the perfect shampoo for your dog.


There are various types of surfactants, but they are broadly classified into two types: ionic surfactants that form electricity when dissolved in water, and nonionic (nonionic) surfactants that do not become ions.


Furthermore, ionic surfactants are divided into the following three types depending on what kind of ion they have.

① Anionic surfactant
② Cation (cation) surfactant
③ Amphoteric surfactant


In addition, the anionic surfactant,

[Higher alcohol type]
[Soap type]
[Amino acid type] etc.

Shampoo agents combine several surfactants to give them various characteristics, but the two main types used are anionic and amphoteric surfactants.

Ingredients are listed in large quantities first.

However, as for cosmetics for human beings, all the ingredients of shampoo agents are obligatory as cosmetics, but shampoos for dogs are treated as miscellaneous goods and may not be fully indicated.
