Betain overfladeaktive stoffer
Det genereres ved reaktionen af fedtholdige tertiære aminer og natriumchloracetat, inklusive cocoylpropylbetain, dodecyl betain, cetylbetain, og lauroylpropylbetain. Det er mildere end de første tre og er i øjeblikket det vigtigste overfladeaktive stof i shampoo til børnehår.
I 1940, det amerikanske DuPont-firma opfandt og anvendte denne type forbindelse. Som aminosyreoverfladeaktive stoffer, denne type overfladeaktive stoffer har en stærk rengøringsevne og lav irritation, og opløsningen er svagt sur. Kæledyrsforsøg har bekræftet, at denne type forbindelse er mindre giftig. Det er et egnet overfladeaktivt middel.

Aminosyre overfladeaktive stoffer
Fremstillet af en kombination af kokosolie og aminosyrer, det er sikkert, mild, og ikke-irriterende. En af de vigtigste pointer er, at den normalt er svagt sur og opfylder pH-kravene til sund og afbalanceret hud og hår. It is the excellent surfactant in infant shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” osv
From the point of view of chemical residential or commercial properties, its pH worth is in between 5.5 og 6.5, which is weakly acidic and near to the pH value of human skin. Derfor, it is mild and skin-friendly and suitable for all hair kinds; amino acid surfactants are zwitterionic and quickly soluble in water. It is easy to wash tidy.
Yet it additionally has limitations. Amino acid surfactants are several to lots of times more pricey than common surfactants, and a lot of are hair shampoos particularly produced infants and little ones. The negative aspects of amino acid surfactants are that they are not abundant in foam and have weak purification ability.
The sensation of solidification and turbidity of surfactants in wintertime is primarily because of the low temperature creating a few of its components to take shape or speed up.

What if surfactant solidifies and comes to be turbid in winter months?
This is a physical sensation and does not have a considerable influence on the performance of surfactants. In order to address this trouble, the adhering to techniques can be taken:
1. Increase the temperature level: Put the surfactant in a warm atmosphere or raise its temperature by heating to ensure that the crystallized or precipitated parts will slowly liquify and the surfactant will return to a clear state. Ikke desto mindre, it must be kept in mind that the temperature must be avoided when heating to avoid affecting the surfactant’s efficiency.
2. Stirring: For surfactants that have actually solidified or come to be turbid, they can be restored to a consistent state by mixing. Stirring can assist crystallized or precipitated ingredients redisperse right into the liquid and boost surfactant quality.
3. Include solvent: Undertiden, a suitable amount of solvent can be included in weaken the surfactant, therefore boosting its coagulation and turbidity. Ikke desto mindre, the added solvent ought to work with the surfactant and needs to not affect its usage effect.
