- shampoos on the market are “2 in 1” shampoos whose function is to wash the hair, but also to provide it with softness.
- surfactants are used, mainly anionic and / or zwitterionic, allowing the shampoo not to be too aggressive for the hair and the scalp.
- Softness is for its part provided by conditioning agents which are either silicone agents or polymers having cationic charges having an affinity for the hair. The higher the cationic charge carried by this polymer, the better is this affinity with the keratin fibers of the hair.
- Coacervation results from the ionic attraction between two compounds of opposite charges.
