Abstract

The present invention provides a microbubble washing composition for washing a human body or an animal, a microbubble washing method using the microbubble washing composition, and a microbubble washing apparatus suitable for carrying out the method are provided which are capable of safely removing sebum and old keratin adhering to the surfaces of the pores in a short period of time, keeping the skin clean for a long period of time, preventing an odor. Specifically, the present invention provides a microbubble washing composition for washing a human body or an animal including a protease and a lipase, a microbubble washing method for washing a human body or an animal including washing a human body or an animal using a washing liquid containing the washing composition and microbubbles, and a microbubble washing apparatus.

Claims

1. A microbubble washing composition for washing a human body or an animal consisting of at least one protease, at least one lipase and at least one alkali metal salt selected from the group consisting of alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal sulfates, alkali halides, and alkali metal salts of boron.

6. The microbubble washing composition according to claim 1, wherein the alkali sulfates are sodium sulfate or potassium sulfate.

2. A microbubble washing method for washing a human body or an animal, the method comprising washing a human body or an animal using microbubbles and a washing liquid composition consisting of at least one protease, at least one lipase and at least one alkali metal salt selected from the group consisting of alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal sulfates, alkali halides, and alkali metal salts of boron.

3. The method according to claim 2, wherein the at least one alkali metal salt in the composition is present in an amount of 80 to 99.5 wt % based on the total amount of the composition.

7. The method according to claim 2, wherein the at least one protease in the composition is present in an amount of 0.01 to 0.5 wt % based on the total amount of the composition, and the at least one lipase is present in an amount of 0.1 to 1.0 wt % based on the total amount of the composition.

8. The method according to claim 2, wherein the microbubbles have a diameter of 50 μ

m or less.

9. The method according to claim 2, wherein the microbubbles are negatively charged.

10. The method according to claim 9, which further comprises filtering out contaminants released from the subject during the washing step.

11. The microbubble washing method according to claim 2, wherein the alkali sulfates are sodium sulfate or potassium sulfate.

4. The method of washing, wherein the washing liquid composition consists of the at least one protease, the at least one lipase, the at least one alkali metal salt, and at least one silica-based desiccant.

5. The method according to claim 4, wherein the composition contains the at least one silica-based desiccant in an amount of 0.01 to 1 wt % based on the total amount of the composition.
