  • the stability of PECs may be compromised due to the presence of other ingredients, especially charged compounds and polymers that could disrupt the PEC structure.
  • the usefulness of PECs may be limited by their compatibility with other ingredients that may be desirable to include in a hair care composition. Since multiple properties are often desired in hair care compositions, it would be desirable to formulate hair care compositions that include stable combinations of PECs with other hair care ingredients that provide additional desirable properties.
  • WO2012/054243 discloses hair compositions with PEC.

  • the present invention provides a composition according to claim 1 .
  • PEC can be stably incorporated into hair conditioning compositions with lamellar conditioning gel phase if the PEC is added to the composition after formation of the conditioning gel phase and not before it. This is in contrast to what is disclosed in the prior art which suggests that further thickening materials such as PQ-37 or PEG are required to maintain structure.
  • the compositions disclosed in the prior art do not refer to compositions with conditioning gel phases and instead relate solely to compositions comprising materials with conditioning capability without the need for lamellar phase. The PEC is thus added to the conditioning gel phase and not formed within the gel phase and is not prepared separately and the gel phase added to it.

Adjustment of the pH alters the percent of ionizable groups that are ionized and thus adjusts the number of groups that may interact through ionic bonds. Production of phase diagrams at varying pHs can be used to determine the proper pH for PEC formation.

The positive charges of the polyquat-28 polymer are attracted to the negatively charged hair fibers and are substantive to the hair. Since the negatively charged PVMMA polymer is complexed to the polyquat-28, the PVMMA also is drawn to the hair. The ends of the split-end are then adhered together through the adhesive action of multiple PECs interacting with the ends of the split-end and/or each other (e.g., in film- formation where the film contracts while drying).
