Betaine surfactants
It is generated by the reaction of fatty tertiary amines and sodium chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first 3 and is currently the major surfactant in baby hair shampoo.
In 1940, the American DuPont Company invented and used this kind of compound. Like amino acid surfactants, this sort of surfactant has strong detergency and low irritation, and the service is weakly acidic. Animal experiments have confirmed that this sort of material is less poisonous. It is an excellent surfactant.

Amino acid surfactants
Made from a combination of coconut oil and amino acids, it is risk-free, gentle, and non-irritating. One of the most important thing is that it is normally weakly acidic and fulfills the pH needs of healthy skin and hair. It is the suitable surfactant in baby shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the point of view of chemical buildings, its pH worth is between 5.5 and 6.5, which is weakly acidic and close to the pH value of human skin. Thus, it is mild and skin-friendly and ideal for all hair types; amino acid surfactants are zwitterionic and easily soluble in water. It is very easy to rinse clean.
However it additionally has constraints. Amino acid surfactants are numerous to dozens of times much more expensive than average surfactants, and many are hair shampoos specially produced infants and young kids. The disadvantages of amino acid surfactants are that they are not abundant in foam and have weak purification capability.
The phenomenon of solidification and turbidity of surfactants in wintertime is mostly as a result of the reduced temperature level triggering several of its components to crystallize or precipitate.

What happens if surfactant solidifies and ends up being turbid in winter?
This is a physical phenomenon and does not have a significant impact on the performance of surfactants. In order to address this trouble, the complying with methods can be taken:
1. Enhance the temperature: Place the surfactant in a warm atmosphere or boost its temperature level by heating to ensure that the crystallized or sped up elements will slowly dissolve and the surfactant will certainly return to a clear state. However, it ought to be kept in mind that the temperature should be prevented when heating to stay clear of influencing the surfactant’s efficiency.
2. Mixing: For surfactants that have strengthened or become turbid, they can be brought back to an uniform state by stirring. Stirring can help crystallized or sped up components redisperse right into the fluid and boost surfactant quality.
3. Add solvent: Sometimes, an ideal quantity of solvent can be included in dilute the surfactant, thereby improving its coagulation and turbidity. Nonetheless, the included solvent must work with the surfactant and needs to not influence its use effect.
