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 initial three and is currently the main surfactant in infant shampoo.

In 1940, the American DuPont Firm designed and applied this kind of compound. Like amino acid surfactants, this type of surfactant has strong detergency and low irritation, and the option is weakly acidic. Pet experiments have actually proven that this type of material is less harmful. It is an optimal surfactant.

Amino acid surfactants

Made from a mix of coconut oil and amino acids, it is safe, gentle, and non-irritating. One of the most essential point is that it is naturally weakly acidic and satisfies the pH demands of healthy and balanced skin and hair. It is the optimal surfactant in infant hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” and so on

From the perspective of chemical residential properties, its pH value is in between 5.5 and 6.5, which is weakly acidic and near to the pH value of human skin. Thus, it is gentle and skin-friendly and suitable for all hair kinds; amino acid surfactants are zwitterionic and quickly soluble in water. It is very easy to wash clean.

But it likewise has limitations. Amino acid surfactants are numerous to dozens of times more pricey than common surfactants, and a lot of are hair shampoos specifically made for infants and young kids. The negative aspects of amino acid surfactants are that they are not abundant in foam and have weak decontamination capability.

The sensation of solidification and turbidity of surfactants in wintertime is primarily because of the reduced temperature triggering a few of its components to crystallize or precipitate.

What happens if surfactant solidifies and comes to be turbid in winter?

This is a physical sensation and does not have a substantial effect on the performance of surfactants. In order to fix this trouble, the following methods can be taken:

1. Enhance the temperature level: Put the surfactant in a cozy environment or increase its temperature by heating so that the taken shape or sped up elements will gradually dissolve and the surfactant will go back to a clear state. Nevertheless, it should be kept in mind that the temperature level should be prevented when heating to avoid influencing the surfactant’s performance.

2. Mixing: For surfactants that have solidified or ended up being turbid, they can be restored to an uniform state by mixing. Stirring can assist taken shape or sped up components redisperse right into the liquid and boost surfactant clarity.

3. Add solvent: In some cases, a suitable amount of solvent can be added to thin down the surfactant, thereby boosting its coagulation and turbidity. Nonetheless, the included solvent should work with the surfactant and must not impact its usage impact.
