Betaine surfactants
It is generated by the response of fatty tertiary amines and sodium chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the first 3 and is currently the primary surfactant in child hair shampoo.
In 1940, the American DuPont Business created and applied this type of compound. Like amino acid surfactants, this type of surfactant has strong detergency and low inflammation, and the solution is weakly acidic. Pet experiments have proven that this type of compound is much less toxic. 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 vital point is that it is naturally weakly acidic and fulfills the pH requirements of healthy and balanced skin and hair. It is the suitable surfactant in baby shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” and so on
From the perspective of chemical properties, its pH value is in between 5.5 and 6.5, which is weakly acidic and near the pH worth of human skin. Thus, it is mild and skin-friendly and ideal for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is very easy to rinse tidy.
Yet it also has constraints. Amino acid surfactants are several to lots of times a lot more expensive than ordinary surfactants, and the majority of are hair shampoos particularly produced infants and little ones. The drawbacks of amino acid surfactants are that they are not rich in foam and have weak purification ability.
The phenomenon of solidification and turbidity of surfactants in winter is mostly as a result of the low temperature level causing several of its elements to crystallize or precipitate.

What if surfactant solidifies and comes to be turbid in winter season?
This is a physical phenomenon and does not have a considerable influence on the performance of surfactants. In order to resolve this problem, the adhering to techniques can be taken:
1. Boost the temperature: Put the surfactant in a warm environment or enhance its temperature by heating to make sure that the taken shape or precipitated components will gradually liquify and the surfactant will certainly return to a clear state. However, it ought to be kept in mind that the temperature level needs to be avoided when warming to avoid impacting the surfactant’s performance.
2. Stirring: For surfactants that have strengthened or become turbid, they can be recovered to an uniform state by stirring. Mixing can assist crystallized or precipitated active ingredients redisperse right into the fluid and improve surfactant clearness.
3. Add solvent: In some cases, a suitable amount of solvent can be contributed to weaken the surfactant, consequently enhancing its coagulation and turbidity. Nonetheless, the included solvent ought to be compatible with the surfactant and ought to not affect its use result.
