Abstract

A multi-phase personal care composition is described that comprises a first visually distinct structured phase and a second visually distinct structured phase. The first visually distinct structured phase comprises a cleansing phase that includes about 2% to about 23.5%, by weight of the cleansing phase, of surfactant component. Preferably, the surfactant component comprises at least one branched anionic surfactant.

Claims

1. A multi-phase personal care composition comprising:

a. a first visually distinct structured cleansing phase comprising;

i. from about 2% to about 21% by weight of said first visually distinct structured cleansing phase, comprising at least one branched anionic surfactant;

ii. from about 0.5% to about 5.0%, by weight of said first visually distinct structured cleansing phase, of a nonionic surfactant having an HLB from about 3.4 to about 15.0 selected from the group consisting of ethoxylated alcohols, glyceryl monohydroxystearate, steareth-2, laureth-2, isosteareth-2, propylene glycol stearate, PEG-2 stearate, sorbitan monostearate, glyceryl stearate, glyceryl laurate and mixtures thereof;

iii. 3.0% or greater, by weight of said first visually distinct structured cleansing phase, of an amphoteric or zwitterionic surfactant;

iv. from about 1% to about 6% by weight of said first visually distinct structured cleansing phase of an electrolyte;

vi. from about 0.1% to about 0.5% by weight of said first visually distinct structured cleansing phase, of gas filled microspheres; and

b. a second visually distinct benefit phase.

2. The multi-phase personal care composition of claim 1, wherein said branched anionic surfactant is selected from the group consisting of sodium trideceth sulfate, sodium tridecyl sulfate, ammonium trideceth sulfate, ammonium tridecyl sulfate, monomethyl branched surfactants and mixtures thereof.

3. The multi-phase personal care composition of claim 1, wherein said branched anionic surfactant comprises monomethyl branched surfactants.

4. The multi-phase personal care composition of claim 1, wherein said cleansing phase provides a Yield Stress of greater than about 1.5 Pascal.

5. The multi-phase personal care composition of claim 1, wherein said composition further comprises a polymeric phase structurant.

6. The multi-phase personal care composition of claim 5, wherein said polymeric phase structurant is selected from the group consisting of deflocculating polymers, naturally derived polymers, synthetic polymers, crosslinked polymers, block polymers, block copolymers, copolymers, hydrophilic polymers, nonionic polymers, anionic polymers, hydrophobic polymers, hydrophobically modified polymers, associative polymers, oligomers, and mixtures thereof.

7. The multi-phase personal care composition of claim 5, wherein said composition comprises from about 0.05% to about 10%, by weight of said cleansing phase, of said polymeric phase structurant.

8. The multi-phase personal care composition of claim 1, wherein said second visually distinct phase is a benefit phase comprises hydrophobic material with a Vaughan Solubility Parameter of from about 5 to about 15.

9. The structured multi-phase personal care composition of claim 1, wherein said benefit phase has a Consistency Value (K) of from about 30 to about 350 Pa-s.

10. The structured multi-phase personal care composition of claim 1, wherein said first visually distinct phase and said second visually distinct phase form a pattern.

11. The structured multi-phase personal care composition of claim 10, wherein said pattern is selected from the group consisting of striped, geometric, marbled, and combinations thereof.

12. The structured multi-phase personal care composition of claim 10, wherein said composition is packaged in a container such that said pattern is visible through said container.

13. The structured multi-phase personal care composition of claim 1, wherein said cleansing phase further comprises a liquid crystalline phase inducing structurant.

14. The structured multi-phase personal care composition of claim 13, wherein said liquid crystalline phase inducing structurant is selected from the group consisting of fatty acids, fatty alcohols, fatty esters, trihydroxystrearin, and mixtures thereof.

15. The structured multi-phase personal cleansing composition of claim 1, wherein said composition further comprises a optional benefit component, wherein said benefit component are selected from the group consisting of emollients, particles, beads, skin whitening agents, fragrances, colorants, vitamins and derivatives thereof, sunscreens, preservatives, anti-acne medicaments, antioxidant, chelators, essential oils, skin sensates, antimicrobial, and mixtures thereof.
