Surfactants (superficially active substances (SAS) is a group of substances that cause the reduction of the surface tension at the breaking point of phases of the substances that do not dissolve in each other.
Operational principle of SAS: If you wash your oily hands with water, you would not clean them, because water molecules don’t “stick” to the molecules of fat. So, to wash it off you need somehow to attach mud molecules to molecules of water. And here SAS ( soap in your case) makes a rescue performing the role of a bounding substance.
Classification of surfactants and their features:
Ionic surfactants are the most widely used.
– low cost;
– a good cleaning effect.
– the most aggressive to human body;
– sensitive to water hardness.
Cationic surfactants in small dosage act as emollients, antistatic agents and disinfectants, mainly used in shampoos and shower gels.
– antibacterial ;
-low functional properties
Nonionic surfactants is the second most popular group of SAS.
– good effect on fabric;
– positive impact on the hair structure ;
-high washing effect;
-stabilize the foam;
Amphoteric surfactants -depending on pH environment act as cationic or ionic ones.
- the saftiest among all surfactants
- stable in hard water
