Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition which is excellent in foaming power and foam quality and has a good feel on the skin and hair after use.

[0002]

2. Description of the Related Art Conventionally, phosphate ester type surfactants are
It is used as the main component of shampoos and skin cleansers because it is mild to the skin (Japanese Patent Publication No. 55-9).
033, Japanese Patent Publication No. 57-47959). However, especially when a monoalkyl phosphate ester is used alone as a main component of a detergent, it has a drawback that the foaming power and foam quality are not sufficient, so that it is preferable to use it in combination with other surfactants. Proposed (Japanese Patent Publication No. 2-466)
39, Japanese Patent Publication No. 6-33404, etc.).

Here, as the surfactant used in combination with the phosphoric acid ester, various betaine type surfactants are widely used because of the excellent foaming effect of the phosphoric acid ester. Examples of such betaine-type surfactants include hydroxysulfobetaine described in Japanese Patent Publication No. 2-46639 and amidopropyl betaine described in Japanese Patent Publication No. 6-33404. Both of them did not satisfy both the foaming power and the foam quality, and even if they were combined with a phosphoric acid ester, they were not sufficiently satisfactory in terms of feeling after washing, particularly moist feeling.

Further, a short-chain dialkyl or dialkenyl phosphate having a carbon number of 9 or less is effective in maintaining the foaming property of other phosphoric acid ester, and a composition containing these and an amphoteric surfactant. The thing is also proposed (Japanese Patent Laid-Open No. 2-1
No. 93910). However, detergents containing these short chain dialkyl or dialkenyl phosphates are
The feeling after washing was not satisfactory.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention has excellent foaming properties, creamy foam quality, and skin after washing, while maintaining the feature of the phosphoric acid ester type surfactants having low irritation. It is an object of the present invention to provide a detergent composition having a good feel of the like.

[0006]

Under such circumstances, the inventors of the present invention have conducted diligent research, and as a result, if a phosphate ester surfactant and hydroxysulfobetaine having a specific amide group were used in combination, It has been found that a detergent composition having excellent foaming properties, having a creamy foam quality, and having a good feel on the skin after washing and the like can be obtained even without containing a short-chain dialkyl or dialkenyl phosphate. Completed the invention.

That is, the present invention comprises the following components (A) and (B): (A) a phosphoric acid ester-based surfactant represented by the general formula (1) or this and a general formula (2). Which is a mixture with a phosphoric acid ester surfactant, the content weight ratio of which is (1) / (2) = 100/0 to 70/30.
