Furthermore, there are indications of critical concentrations for each of these components and that in the entangled region, the modulus of the coacervate is that of a crosslinked gel, whereas in the dilute region, the coacervate is a viscous liquid.
Coacervates are tiny spherical droplets of assorted organic molecules (specifically, lipid molecules) that are held together by hydrophobic forces from a surrounding liquid.

Conventional conditioning shampoos contain cationic polymers that form complex coacervates with anionic surfactants.

In the case of the Rhodia polymers, hindered drainage of the lamellar liquid could be caused by adsorption of the cationic entities at the lamellar surface with the non-ionic and/or anionic blocks in the lamellar liquid, Alternatively, formation of phase-separated coacervates between the cationic polymer and the anionic surfactant could result in blockage of the plateau border Of course, if the interaction of the cationic polymer is strong enough to form "inverse micellar" structures, then the phase-separated particles could cause a local reversal of the curvature in the lamellae, resulting in breakage of the lamellar film and subsequent foam destabilization.
BASF researchers have pronounced that they have created ampholytic terpolymers for 2-in-l shampoos that have a strong affinity for keratin substrates even in the presence of anionic surfactants, can provide conditioning on their own due to the presence of a hydrophobic monomer, form complexes with anionic, fatty amines and cationic surfactants for stimuli-responsive deposition for hair conditioning, and they form complex coacervates that can act as deposition aids for silicones beneficial agents.
11,12) Polymer-surfactant coacervates phase separate by dilution of this type of conditioning shampoo and these coacervates apparently are also able to enhance the deposition of the antidandruff ingredient.
Complex coacervates prepared by the interaction of cationic and anionic polyelectrolytes can be employed as encapsulants.
