Betaine surfactants
It is produced 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 first 3 and is presently the main surfactant in baby shampoo.
In 1940, the American DuPont Company developed and applied this type of substance. Like amino acid surfactants, this sort of surfactant has strong detergency and reduced irritation, and the solution is weakly acidic. Pet experiments have actually verified that this sort of compound is less hazardous. It is an excellent surfactant.

Amino acid surfactants
Made from a mix of coconut oil and amino acids, it is risk-free, gentle, and non-irritating. The most vital thing is that it is normally weakly acidic and meets the pH demands of healthy and balanced skin and hair. It is the perfect surfactant in baby hair shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the viewpoint of chemical residential or commercial properties, its pH worth is in between 5.5 and 6.5, which is weakly acidic and near to the pH value of human skin. Hence, it is gentle and skin-friendly and ideal for all hair kinds; amino acid surfactants are zwitterionic and easily soluble in water. It is easy to wash clean.
But it likewise has restrictions. Amino acid surfactants are several to dozens of times much more expensive than ordinary surfactants, and most are shampoos specially created infants and young kids. The disadvantages of amino acid surfactants are that they are not rich in foam and have weak purification capability.
The phenomenon of solidification and turbidity of surfactants in winter season is primarily as a result of the low temperature level causing several of its components to take shape or precipitate.

Suppose surfactant solidifies and becomes turbid in winter season?
This is a physical sensation and does not have a substantial effect on the efficiency of surfactants. In order to resolve this issue, the following approaches can be taken:
1. Increase the temperature level: Place the surfactant in a cozy setting or enhance its temperature level by home heating to ensure that the taken shape or sped up elements will gradually liquify and the surfactant will return to a clear state. However, it should be noted that the temperature level ought to be stayed clear of when warming to stay clear of affecting the surfactant’s performance.
2. Stirring: For surfactants that have solidified or ended up being turbid, they can be restored to a consistent state by mixing. Mixing can aid taken shape or sped up components redisperse into the liquid and enhance surfactant clearness.
3. Include solvent: In many cases, an ideal amount of solvent can be added to thin down the surfactant, thereby improving its coagulation and turbidity. Nonetheless, the included solvent must work with the surfactant and needs to not affect its usage effect.
