Betaine surfactants
It is produced by the reaction of fatty tertiary amines and sodium chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the initial 3 and is currently the major surfactant in child shampoo.
In 1940, the American DuPont Company developed and applied this kind of compound. Like amino acid surfactants, this kind of surfactant has solid detergency and reduced irritability, and the service is weakly acidic. Animal experiments have shown that this type of substance is less hazardous. It is an excellent surfactant.

Amino acid surfactants
Made from a combination of coconut oil and amino acids, it is safe, mild, and non-irritating. The most important point is that it is naturally weakly acidic and fulfills the pH demands of healthy skin and hair. It is the suitable surfactant in infant shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the perspective of chemical buildings, its pH value is in between 5.5 and 6.5, which is weakly acidic and near the pH value of human skin. Therefore, it is mild and skin-friendly and suitable for all hair types; amino acid surfactants are zwitterionic and conveniently soluble in water. It is very easy to rinse tidy.
Yet it additionally has restrictions. Amino acid surfactants are several to dozens of times a lot more costly than ordinary surfactants, and a lot of are hair shampoos specifically made for infants and children. The negative aspects of amino acid surfactants are that they are not abundant in foam and have weak decontamination capacity.
The phenomenon of solidification and turbidity of surfactants in winter months is mostly because of the low temperature level causing some of its elements to crystallize or speed up.

What if surfactant solidifies and comes to be turbid in winter months?
This is a physical phenomenon and does not have a considerable influence on the performance of surfactants. In order to fix this trouble, the following approaches can be taken:
1. Increase the temperature: Put the surfactant in a warm environment or enhance its temperature level by home heating to ensure that the crystallized or sped up components will gradually liquify and the surfactant will certainly go back to a clear state. Nevertheless, it must be noted that the temperature needs to be avoided when warming to stay clear of influencing the surfactant’s performance.
2. Stirring: For surfactants that have strengthened or come to be turbid, they can be restored to a consistent state by stirring. Stirring can help crystallized or sped up components redisperse right into the liquid and boost surfactant clearness.
3. Include solvent: Sometimes, an appropriate amount of solvent can be added to weaken the surfactant, consequently enhancing its coagulation and turbidity. Nevertheless, the added solvent must work with the surfactant and should not influence its use effect.
