Abstract

A mild, multi-phase cleansing composition is described that includes a cleansing phase including a structured surfactant component has a first density; a benefit phase includes an emulsion, the benefit phase has a second density and a density modifier; wherein the first density differs from the second density by less than 0.15 g/cm³; the structured surfactant component includes at least one surfactant and provides a Total Lather Volume of at least about 600 ml. The emulsion is either an oil in water or an oil in water emulsion.

Claims

1. A mild, multi-phase personal cleansing composition comprising:

(i) a cleansing phase comprising a structured surfactant component and water;

said cleansing phase having a first density;

wherein said structured surfactant component comprises low density microspheres having a density of less than 0.7 g/cm³ and at least one surfactant; and

wherein said structured surfactant component provides a Total Lather Volume of at least 600 ml;

(ii) a benefit phase comprising an emulsion and optionally, high density particles having a density greater than 1.1 g/cm³;

said benefit phase having a second density;

wherein said first density differs from said second density by less than 0.15 g/cm³; and

wherein the personal cleansing composition has a density of less than 0.97 g/cm³.

2. The mild, multi-phase personal cleansing composition according to claim 1 wherein said low density microsphere is selected from the group consisting of inorganic material, organic material and mixtures thereof.

3. The mild, multi-phase cleansing composition of claim 1, wherein said structured surfactant component provides a Total Lather Volume of at least about 800 ml.

4. The mild, multi-phase cleansing composition of claim 1, wherein said structured surfactant component provides a Yield Point of greater than about 0.5 Pascal.

5. The mild, multi-phase cleansing composition of claim 1, comprising from about 1% to about 95%, by weight of the composition, of said structured surfactant component.

6. The mild, multi-phase cleansing composition of claim 1, wherein said surfactant is selected from the group consisting of anionic surfactant, nonionic surfactant, zwitterionic surfactant, cationic surfactant, amphoteric surfactant, soap, and mixtures thereof.

7. The mild, multi-phase cleansing composition of claim 6 wherein said anionic surfactant is selected from the group consisting of alkyl ether sulfates, alkyl sulfonates and mixtures thereof.

8. The mild, multi-phase cleansing composition of claim 6, wherein said amphoteric surfactant is selected from the group consisting of sodium lauroamphoacetate, sodium cocoamphoactetate, disodium lauroamphoacetate, and disodium cocodiamphoacetate, and mixtures thereof.

9. The mild, multi-phase cleansing composition of claim 6, wherein said nonionic surfactant is selected from the group consisting of glyceryl monohydroxystearate, steareth-2, propylene glycol stearate, sorbitan monostearate, glyceryl stearate, laureth-2, and mixtures thereof.

10. The mild, multi-phase cleansing composition of claim 6, comprising from about 0.1% to about 50%, by weight of said structured surfactant component, of said nonionic surfactant.

11. The mild, multi-phase cleansing composition of claim 10, wherein said nonionic surfactant has an HLB of from about 1.5 to about 15.0.

12. The mild, multi-phase cleansing composition of claim 1, wherein said composition comprises a structured domain wherein said structured domain is an opaque structured domain.
