Betaine surfactants

It is created by the reaction of fatty tertiary amines and sodium chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first three and is presently the primary surfactant in infant hair shampoo.

In 1940, the American DuPont Company invented and used this sort of substance. Like amino acid surfactants, this kind of surfactant has solid detergency and low irritability, and the option is weakly acidic. Pet experiments have verified that this kind of material is less harmful. It is an ideal surfactant.

Amino acid surfactants

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

From the viewpoint of chemical properties, its pH value is between 5.5 and 6.5, which is weakly acidic and near to the pH worth of human skin. Hence, it is gentle and skin-friendly and suitable for all hair types; amino acid surfactants are zwitterionic and quickly soluble in water. It is easy to rinse clean.

Yet it likewise has restrictions. Amino acid surfactants are numerous to lots of times much more pricey than ordinary surfactants, and many are hair shampoos particularly created infants and little ones. The downsides of amino acid surfactants are that they are not rich in foam and have weak purification capacity.

The sensation of solidification and turbidity of surfactants in winter season is mostly due to the reduced temperature creating some of its parts to crystallize or speed up.

Suppose surfactant solidifies and ends up being turbid in winter months?

This is a physical phenomenon and does not have a considerable effect on the performance of surfactants. In order to resolve this problem, the complying with methods can be taken:

1. Increase the temperature: Place the surfactant in a warm environment or enhance its temperature level by heating to make sure that the crystallized or sped up components will gradually dissolve and the surfactant will go back to a clear state. However, it should be kept in mind that the temperature should be prevented when heating up to avoid influencing the surfactant’s efficiency.

2. Mixing: For surfactants that have actually strengthened or ended up being turbid, they can be restored to a consistent state by stirring. Mixing can assist crystallized or precipitated active ingredients redisperse right into the fluid and improve surfactant clearness.

3. Add solvent: In many cases, an ideal amount of solvent can be added to thin down the surfactant, consequently boosting its coagulation and turbidity. Nonetheless, the added solvent need to be compatible with the surfactant and ought to not affect its usage effect.
