Betaine surfactants
It is generated by the response of fatty tertiary amines and salt chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first three and is presently the main surfactant in infant hair shampoo.
In 1940, the American DuPont Company developed and used this type of substance. Like amino acid surfactants, this type of surfactant has strong detergency and low inflammation, and the service is weakly acidic. Animal experiments have actually shown that this kind of material is much less toxic. It is an optimal surfactant.

Amino acid surfactants
Made from a mix of coconut oil and amino acids, it is safe, mild, and non-irritating. One of the most crucial thing is that it is normally weakly acidic and meets the pH demands of healthy and balanced skin and hair. It is the optimal surfactant in infant shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” and so on
From the viewpoint of chemical residential or commercial properties, its pH value is between 5.5 and 6.5, which is weakly acidic and close to the pH worth of human skin. Therefore, it is gentle and skin-friendly and ideal for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is simple to rinse tidy.
Yet it likewise has restrictions. Amino acid surfactants are numerous to loads of times a lot more pricey than ordinary surfactants, and many are hair shampoos specially created infants and young kids. The negative aspects of amino acid surfactants are that they are not abundant in foam and have weak decontamination ability.
The phenomenon of solidification and turbidity of surfactants in winter months is mainly due to the low temperature triggering some of its parts to take shape or precipitate.

Suppose surfactant solidifies and comes to be turbid in wintertime?
This is a physical sensation and does not have a considerable impact on the performance of surfactants. In order to resolve this problem, the adhering to methods can be taken:
1. Increase the temperature level: Place the surfactant in a cozy setting or boost its temperature level by heating to make sure that the taken shape or sped up parts will progressively dissolve and the surfactant will go back to a clear state. However, it should be noted that the temperature ought to be stayed clear of when warming to stay clear of influencing the surfactant’s performance.
2. Mixing: For surfactants that have solidified or come to be turbid, they can be brought back to an uniform state by stirring. Stirring can help taken shape or precipitated ingredients redisperse into the liquid and improve surfactant quality.
3. Include solvent: In some cases, an appropriate quantity of solvent can be included in dilute the surfactant, therefore enhancing its coagulation and turbidity. Nonetheless, the added solvent ought to be compatible with the surfactant and must not impact its use effect.
