Betaine surfactants
It is created by the response of fatty tertiary amines and salt chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first three and is currently the main surfactant in baby shampoo.
In 1940, the American DuPont Business developed and used this kind of compound. Like amino acid surfactants, this type of surfactant has strong detergency and low inflammation, and the remedy is weakly acidic. Pet experiments have confirmed that this kind of material is much less harmful. It is an optimal surfactant.

Amino acid surfactants
Made from a combination 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 satisfies the pH requirements of healthy and balanced skin and hair. It is the optimal surfactant in infant shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the point of view of chemical residential or commercial properties, its pH worth is in between 5.5 and 6.5, which is weakly acidic and near the pH worth of human skin. Thus, it is mild and skin-friendly and ideal for all hair types; amino acid surfactants are zwitterionic and quickly soluble in water. It is easy to wash tidy.
Yet it also has constraints. Amino acid surfactants are several to loads of times much more expensive than common surfactants, and a lot of are hair shampoos specially made for babies and kids. The drawbacks of amino acid surfactants are that they are not abundant in foam and have weak decontamination capacity.
The phenomenon of solidification and turbidity of surfactants in winter is mostly because of the reduced temperature level triggering a few of its elements to take shape or precipitate.

Suppose surfactant solidifies and comes to be turbid in winter months?
This is a physical phenomenon and does not have a considerable effect on the effectiveness of surfactants. In order to solve this issue, the adhering to approaches can be taken:
1. Boost the temperature: Position the surfactant in a cozy setting or increase its temperature by home heating so that the crystallized or precipitated components will gradually liquify and the surfactant will go back to a clear state. Nevertheless, it should be noted that the temperature needs to be avoided when heating up to avoid influencing the surfactant’s performance.
2. Mixing: For surfactants that have solidified or come to be turbid, they can be brought back to a consistent state by stirring. Stirring can aid taken shape or sped up active ingredients redisperse right into the fluid and enhance surfactant clarity.
3. Add solvent: In some cases, an appropriate quantity of solvent can be included in thin down the surfactant, consequently boosting its coagulation and turbidity. However, the added solvent need to be compatible with the surfactant and ought to not impact its usage result.
