Abstract

The present invention relates to a personal care composition containing a gel-network phase, a stability agent, a structured oil phase and an aqueous phase. This particular combination of materials, specifically gel-network emulsifiers in combination with stabilizing polymers, provide for products which have excellent application aesthetics and yet deposit significant levels of beneficial lipids even when rinsed off. Additionally, the present invention relates to a method of using a wet skin personal care composition that contains a gel-network phase, a stability agent, a structured oil phase and an aqueous phase.

Claims

1. An oil-containing composition comprising:

a) an aqueous phase;

b) from about 1 to about 80 weight percent of a structured oil phase;

c) a gel-network phase comprising a non-ionic hydrophilic surfactant and a hydrophobic structuring agent; and

d) an aqueous phase stability agent

wherein said structured oil phase has a shear index of less than 0.8.

2. The composition of claim 1, comprising at least 10 weight percent of said structured oil phase.

3. The composition of claim 1, comprising at least 20 weight percent of said structured oil phase.

4. The composition of claim 1, wherein said structured oil phase is petrolatum.

5. The composition of claim 1, wherein said gel-network phase is present in an amount from about 1 to about 20 weight percent of said composition.

6. The composition of claim 1, wherein said gel-network phase is present in an amount from about 0.5 to about 20 weight percent of said composition.

7. The composition of claim 1, wherein said gel-network phase is present in an amount from about 1 to about 10 weight percent of said composition.

8. The composition of claim 1, wherein said aqueous phase stability agent is a modified starch.

9. A method of depositing oils on a substrate comprising applying an oil-containing composition to a substrate, said oil-containing composition comprising:

a) an aqueous phase;

b) from about 1 to about 80 weight percent of a structured oil phase;

c) a gel-network phase comprising a non-ionic hydrophilic surfactant and a hydrophobic structuring agent; and

d) an aqueous phase stability agent

wherein said structured oil phase has a shear index of less than 0.8.

10. The method of claim 9, wherein said oil-containing composition comprises at least 10 weight percent of said structured oil phase.

11. The method of claim 9, wherein said oil-containing composition comprises at least 20 weight percent of said structured oil phase.

12. The method of claim 9, wherein said gel-network phase is present in an amount from about 0.5 to about 20 weight percent of said composition.

13. The method of claim 9, wherein said gel-network phase is present in an amount from about 1 to about 10 weight percent of said composition.

14. The method of claim 9, wherein said structured oil phase is petrolatum.

15. The method of claim 9, wherein said aqueous phase stability agent is a modified starch.
