Betaine surfactants
It is generated by the response of fatty tertiary amines and sodium chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first three and is currently the primary surfactant in child hair shampoo.
In 1940, the American DuPont Firm invented and used this kind of compound. Like amino acid surfactants, this kind of surfactant has strong detergency and low irritability, and the option is weakly acidic. Animal experiments have shown that this type of substance is much less hazardous. It is a perfect surfactant.

Amino acid surfactants
Made from a mix of coconut oil and amino acids, it is risk-free, gentle, and non-irritating. The most vital point is that it is naturally weakly acidic and satisfies the pH requirements of healthy skin and hair. It is the ideal surfactant in baby hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” and so on
From the point of view of chemical residential properties, its pH value is between 5.5 and 6.5, which is weakly acidic and near to the pH worth of human skin. Hence, it is gentle and skin-friendly and appropriate for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is simple to wash tidy.
However it also has limitations. Amino acid surfactants are several to dozens of times more costly than common surfactants, and many are hair shampoos specially made for babies and children. The drawbacks of amino acid surfactants are that they are not abundant in foam and have weak purification capacity.
The sensation of solidification and turbidity of surfactants in winter is primarily because of the reduced temperature creating several of its elements to crystallize or speed up.

What if surfactant solidifies and comes to be turbid in wintertime?
This is a physical sensation and does not have a substantial influence on the efficiency of surfactants. In order to solve this trouble, the following techniques can be taken:
1. Raise the temperature level: Put the surfactant in a warm setting or increase its temperature by heating to make sure that the taken shape or precipitated elements will slowly dissolve and the surfactant will go back to a clear state. However, it must be kept in mind that the temperature level should be prevented when warming to stay clear of impacting the surfactant’s efficiency.
2. Mixing: For surfactants that have strengthened or become turbid, they can be brought back to a consistent state by mixing. Stirring can aid taken shape or sped up active ingredients redisperse right into the fluid and improve surfactant clearness.
3. Add solvent: Sometimes, an appropriate amount of solvent can be added to water down the surfactant, consequently enhancing its coagulation and turbidity. Nonetheless, the included solvent should work with the surfactant and ought to not impact its use impact.
