Lochhead, University of Southern Mississippi, reported on the correlation of the physicochemical behavior of coacervates normalized with critical overlap concentration of a polymer.
The compositions for producing stable coacervate droplets, at these initial concentrations, were determined by adding 0.
Our results show that as the concentration of NaCl increased, the amount of coacervate formed decreased in the 'ion-exchange' region but increased in the large micelle region.
INVESTIGATION OF THE STRUCTURE OF POLYELECTROLYTE-BASED COMPLEX COACERVATES
Copolymers of diallyldimethylammonium chloride and acrylamide have recently been advanced as coacervate depositing agents for skin, with the added advantage that they provide desired low viscosity/theology to the personal care compositions in which they are included.
The higher molecular weight polymer improves bridging of the silicone in the coacervate to assist deposition while the increased charge reduced looping on the surface to direct the silicone to the hair and also hold hair in its place.
Conventional conditioning shampoos work by a mechanism in which cationic polymers interact with the anionic detersive surfactants to phase separate as a coacervate during the rinse stage.
He was known to many as the father of the modern conditioning shampoo and of coacervate delivery systems.
These cationic polymers operate by depositing a polymer-surfactant complex coacervate that separates as a distinct phase during the rinsing step of the shampoo process.
Using a liquid handling system for sample preparation, we are able to analyze nearly 1000 samples per investigator per day, making it possible to understand electrolyte effects and coacervate structure-property relationships," explained Dr.
The composition is free of anionic water-soluble polymers, random copolymers, block copolymers, coacervates, precipitates and silicone copolymers.
