Betaine surfactants
It is generated by the reaction of fatty tertiary amines and sodium chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the initial 3 and is presently the major surfactant in infant hair 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 inflammation, and the solution is weakly acidic. Animal experiments have verified that this kind of substance is much less toxic. It is an excellent surfactant.

Amino acid surfactants
Made from a mix of coconut oil and amino acids, it is risk-free, mild, and non-irritating. The most vital thing is that it is normally weakly acidic and fulfills the pH requirements of healthy and balanced skin and hair. It is the suitable surfactant in baby hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the point of view of chemical properties, its pH value is between 5.5 and 6.5, which is weakly acidic and near the pH worth of human skin. Therefore, it is mild and skin-friendly and ideal for all hair kinds; amino acid surfactants are zwitterionic and conveniently soluble in water. It is easy to rinse tidy.
But it also has constraints. Amino acid surfactants are a number of to loads of times more costly than common surfactants, and many are hair shampoos specially produced babies and children. The drawbacks of amino acid surfactants are that they are not abundant in foam and have weak decontamination ability.
The sensation of solidification and turbidity of surfactants in winter is generally because of the reduced temperature creating some of its components to crystallize or precipitate.

What happens if surfactant solidifies and becomes turbid in winter?
This is a physical sensation and does not have a significant effect on the effectiveness of surfactants. In order to solve this issue, the adhering to approaches can be taken:
1. Raise the temperature: Position the surfactant in a warm setting or enhance its temperature by heating so that the taken shape or sped up parts will progressively liquify and the surfactant will certainly return to a clear state. Nevertheless, it needs to be noted that the temperature should be prevented when heating to prevent affecting the surfactant’s performance.
2. Stirring: For surfactants that have actually strengthened or come to be turbid, they can be brought back to a consistent state by stirring. Stirring can aid taken shape or sped up ingredients redisperse into the liquid and enhance surfactant clearness.
3. Add solvent: Sometimes, an appropriate amount of solvent can be included in thin down the surfactant, therefore improving its coagulation and turbidity. Nevertheless, the included solvent should be compatible with the surfactant and needs to not impact its use result.
