Benefits of technology

[0005] The present invention relates to a multi-phase personal cleansing compositions comprising a structured aqueous cleansing phase and at least one aqueous phase wherein at least one phase comprises a non-migrating colorant. The phases are packaged i

Problems solved by technology

The ability to place a cleansing phase in physical contact with a structured aqueous phase and maintain stability for any period of time has proven to be a problem.
The physical contact of a structured aqueous phase and a cleansing phase creates a situation where they are thermodynamically unstable.
Although such dual-chamber delivery systems provide improved cleansing benefits versus conventional systems, it is often difficult to achieve consistent and uniform p

Abstract

A multi-phase personal cleansing composition comprising: (a) a structured aqueous cleansing phase comprising a surfactant and water; and (b) at least one additional, non-lamellar aqueous phase; wherein at least one of said structured aqueous cleansing phase and said additional aqueous phase comprises at least one non-migrating colorant, said non-migrating colorant comprising a cLogP value of at least about 2; and wherein said structured aqueous cleansing phase and said additional aqueous phase are packaged in physical contact with one another.

Description

FIELD OF THE INVENTION [0001] The present invention relates to multi-phase personal cleansing compositions comprising at least one structured aqueous cleansing phase and at least one additional, non-lamellar aqueous phase wherein at least one of the phases comprises at least one non-migrating colorant comprising a cLogP value of at least about 2 and wherein the two phases are packaged in physical contact with one another while remaining stable over time. BACKGROUND OF THE INVENTION [0002] The ability to place a cleansing phase in physical contact with a structured aqueous phase and maintain stability for any period of time has proven to be a problem. The physical contact of a structured aqueous phase and a cleansing phase creates a situation where they are thermodynamically unstable. [0003] One attempt at providing a stable, structured aqueous phase and cleansing phase within a personal cleansing product would be the use of dual-chamber packaging. These packages comprise separate cl...
