Betaine surfactants

It is produced by the response of fatty tertiary amines and sodium chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the initial three and is presently the primary surfactant in baby hair shampoo.

In 1940, the American DuPont Firm created and used this type of substance. Like amino acid surfactants, this type of surfactant has solid detergency and low irritation, and the service is weakly acidic. Animal experiments have verified that this kind of material is much less poisonous. It is an excellent 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 important point is that it is normally weakly acidic and meets the pH requirements 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 point of view 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. Thus, it is gentle and skin-friendly and suitable for all hair types; amino acid surfactants are zwitterionic and conveniently soluble in water. It is simple to rinse tidy.

Yet it also has constraints. Amino acid surfactants are numerous to dozens of times much more pricey than regular surfactants, and many are hair shampoos specially produced babies and children. The disadvantages of amino acid surfactants are that they are not rich in foam and have weak purification capacity.

The phenomenon of solidification and turbidity of surfactants in wintertime is primarily due to the reduced temperature level triggering some of its components to crystallize or speed up.

Suppose surfactant solidifies and comes to be turbid in winter months?

This is a physical phenomenon and does not have a considerable influence on the performance of surfactants. In order to address this problem, the following approaches can be taken:

1. Increase the temperature: Place the surfactant in a cozy setting or boost its temperature level by heating to make sure that the taken shape or precipitated components will slowly dissolve and the surfactant will certainly return to a clear state. Nonetheless, it must be noted that the temperature level should be avoided when heating up to stay clear of impacting the surfactant’s efficiency.

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

3. Add solvent: In some cases, an appropriate quantity of solvent can be added to thin down the surfactant, therefore enhancing its coagulation and turbidity. However, the added solvent must be compatible with the surfactant and must not impact its usage result.
