Abstract

An aqueous cleansing and oily soil removing composition comprising a surface active agent and an agent for removing oily soil from skin, in which the surface active agent and agent for removing oily soil are separate but combinedly dispensable from a single packaging means as discrete domains, preferably in a predetermined ratio. Separating the agent for removing oily soil from the surface active agent results in improved removal of oily soil from skin, and a clean, fresh feel which is appreciated by the consumer.

Claims

1. A cleansing and oily soil removing composition consisting essentially of:

a) an aqueous domain, free of an oily soil removal agent, containing one or more surface active agent(s) selected from the group consisting of anionic, nonionic, amphoteric, and zwitterionic surface active agents, soap and mixtures thereof; and

b) an aqueous or non-aqueous domain, free of a cleansing surface active agent, containing one or more agent(s) for removing oily soil, the nonaqueous domain being in a non-emulsified state;

said agents being selected from the group consisting of polymeric polyols, solid particulate materials of size greater than 10 microns, polyhydric alcohols, ethanol, and mixtures thereof;

wherein the domains are greater than 1000 microns in size and are separate but combinedly dispensable from a single packaging means as discrete domains.

2. A composition according to claim 1, wherein the single packaging means comprises two separate compartments.

3. A composition according to claim 1, wherein one of the domains is in microencapsulated form.

4. A composition according to claim 1, wherein the agent for removing oily soil is thickened with a thickening agent.

5. A composition according to claim 1 wherein the agent for removing oily soil is present in an amount from 1 to 70 wt %.

6. A composition according to claim 1 wherein the agent for removing oily soil is present in an amount from 5 to 50 wt %.

7. A composition according to claim 1, wherein the oily soil is cosmetic make-up.

8. A composition according to claim 1, wherein the aqueous domain containing surface active agent is thickened with a thickening agent.

9. A method for improved removal of oily soil from skin by using a cleasing and oily soil removing liquid composition of claim 1, the method comprising:

i) dispensing the surface active agent and the agent for removing oily soil from a packaging means;

ii) applying the surface active agent and the agent for removing oily soil to the human body; and

iii) removing the resulting mixture of oily soil and cleansing agents by rinsing with water.

10. A method according to claim 9, wherein the surface active agent and the agent for removing oily soil are dispensed from the packaging means.

11. A packaged topical composition comprising a cleansing composition according to claim 1 in a dispensing package.

12. A packaged composition according to claim 11, wherein the package has two or more compartments.
