Betaine surfactants

It is produced by the reaction of fatty tertiary amines and salt chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the first three and is presently the primary surfactant in baby hair shampoo.

In 1940, the American DuPont Business designed and applied this type of compound. Like amino acid surfactants, this kind of surfactant has strong detergency and low irritability, and the service is weakly acidic. Pet experiments have proven that this kind of material is less hazardous. It is a suitable surfactant.

Amino acid surfactants

Made from a mix of coconut oil and amino acids, it is secure, mild, and non-irritating. The most crucial thing is that it is naturally weakly acidic and satisfies the pH needs of healthy and balanced skin and hair. It is the ideal surfactant in infant hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” and so on

From the point of view of chemical homes, 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 gentle and skin-friendly and appropriate for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is simple to rinse tidy.

But it likewise has limitations. Amino acid surfactants are a number of to dozens of times more costly than normal surfactants, and a lot of are hair shampoos specially made for infants and little ones. 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 winter season is generally due to the reduced temperature creating some of its components to take shape or speed up.

What if surfactant solidifies and becomes turbid in wintertime?

This is a physical phenomenon and does not have a considerable effect on the performance of surfactants. In order to address this trouble, the adhering to methods can be taken:

1. Boost the temperature: Put the surfactant in a cozy environment or increase its temperature by home heating so that the taken shape or precipitated parts will slowly dissolve and the surfactant will return to a clear state. Nevertheless, it ought to be noted that the temperature level ought to be stayed clear of when heating to stay clear of influencing the surfactant’s performance.

2. Mixing: For surfactants that have strengthened or ended up being turbid, they can be restored to an uniform state by mixing. Mixing can help taken shape or sped up ingredients redisperse into the liquid and improve surfactant clarity.

3. Add solvent: In some cases, a proper amount of solvent can be contributed to dilute the surfactant, thereby enhancing its coagulation and turbidity. However, the added solvent should be compatible with the surfactant and should not affect its use result.
