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 first 3 and is presently the main surfactant in infant hair shampoo.
In 1940, the American DuPont Firm developed and used this type of substance. Like amino acid surfactants, this type of surfactant has strong detergency and reduced inflammation, and the remedy is weakly acidic. Pet experiments have shown that this kind of substance is less toxic. It is an optimal surfactant.

Amino acid surfactants
Made from a combination of coconut oil and amino acids, it is risk-free, gentle, and non-irritating. One of the most important point is that it is naturally weakly acidic and meets the pH demands of healthy skin and hair. It is the perfect surfactant in baby hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the point of view of chemical properties, its pH worth is between 5.5 and 6.5, which is weakly acidic and near to the pH value of human skin. Hence, it is mild and skin-friendly and ideal for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is easy to rinse tidy.
However it likewise has restrictions. Amino acid surfactants are several to dozens of times extra expensive than common surfactants, and a lot of are shampoos particularly produced babies and young children. The drawbacks of amino acid surfactants are that they are not rich in foam and have weak purification ability.
The sensation of solidification and turbidity of surfactants in wintertime is generally due to the low temperature causing several of its elements to crystallize or speed up.

What if surfactant solidifies and becomes turbid in wintertime?
This is a physical sensation and does not have a considerable influence on the performance of surfactants. In order to fix this issue, the complying with methods can be taken:
1. Increase the temperature: Position the surfactant in a cozy environment or boost its temperature by home heating to ensure that the taken shape or precipitated elements will progressively dissolve and the surfactant will go back to a clear state. However, it needs to be kept in mind that the temperature level should be avoided when warming to stay clear of impacting the surfactant’s performance.
2. Stirring: For surfactants that have strengthened or ended up being turbid, they can be recovered to an uniform state by stirring. Stirring can assist crystallized or sped up components redisperse right into the liquid and improve surfactant clearness.
3. Add solvent: In some cases, a suitable amount of solvent can be included in weaken the surfactant, therefore boosting its coagulation and turbidity. Nevertheless, the included solvent ought to be compatible with the surfactant and needs to not influence its usage result.
