Sashie's work revolves around the belief that the coacervate is a universal model and basis for all systems and organisms, simple and complex.
Coacervates are tiny spherical droplets of assorted organic molecules (specifically, lipid molecules) that are held together by hydrophobic forces from a surrounding liquid.
Detection of nucleic acid bases in photochemically synthesised self-sustaining coacervates.
INVESTIGATING THE EFFECT OF SODIUM CHLORIDE CONCENTRATION ON COMPLEX COACERVATE FORMATION WITHIN A CONCENTRATED REGIME
Polyquaternium compounds are theorized to be useful in forming complex coacervates in the concentrated surfactant regime.
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.
The complex also includes a polymer deposition aid that forms coacervates to help keep the silicones from washing away, acting as a net and capturing other care ingredients and bringing them down to the fabric surface for maximum effect and chlorine scavenger technology, which helps maintain bright colors and prevents dyes from fading by neutralizing chlorine in the wash water.
