Polyelectrolyte Complex for Mending Damaged Hair

A molecular complex is formed by the association of two or more molecules or ions. More specifically, a polyelectrolyte complex (PEC) is made up of differing macromolecules bound together by noncovalent bonds, which include primarily coulombic interactions.1 PECs often are referred to in the patent and technical literature as polymer-polymer complexes, interpolyelectrolyte complexes, or complex coacervates; these terms all are based on the interaction of large macromolecules. Regarding the formation and application of PECs, the authors propose they instead be characterized by the term complex system, as defined by complexity theory.
