6. Ingredients. Surfactants (surfactants) are the basis of any shampoo and play the role of washing, cleansing and foaming components.
The most common surfactant in the formulations of modern shampoos is sodium hydroxyethylated lauryl sulfate - sodium laureth sulfate.
In baby shampoos, soft surfactants (co-surfactants) are mainly used, which are products based on protein hydrolysate and fatty acids, for example, coconut oil. This product is very suitable for creating transparent shampoos.
Thickeners, antistatic agents, preservatives, pH regulators, complexing agents, BAS / dietary supplements, coloring agents, etc. are used as auxiliary raw materials.
Overeating additives. They are used to restore the lipid layer (in other words, to reduce the degreasing effect of shampoo on the scalp and hair). This is especially true for shampoos for the care of dry and damaged hair. These additives give the hair elasticity, shine and improve their appearance.
Overeating additives are mainly fats and oils of natural origin. These include lanolin and its derivatives, almond, coconut, apricot, olive, sesame and other oils. Biologically active additives (dietary supplements). Dietary supplements play an important role in the composition of shampoos: vitamins, plant extracts, algae extracts, fruit acids and others that promote cell renewal, improve hair structure, etc.
