Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning composition, and more particularly to a cleaning composition with improved foaming properties and creaminess.

[Conventional technology and its problems]

Conventionally, cleansing compositions, especially detergents for skin or hair, have not only good foaming properties.

It is required that the foam has a good feel, and various oily substances, water-soluble polymers, etc. have been used for this purpose. However, when these substances are used in large amounts, they have problems such as inhibiting foaming and adversely affecting the stability of the system.

[Means for solving problems]

Therefore, in order to overcome such problems, the present inventors
As a result of extensive research, we found that by incorporating a cationized cyclodextrin represented by the general formula U> below into the surfactant together with a conventionally used surfactant, foaming and system stability were inhibited. They found that the feel of the foam could be improved without any problems, leading to the completion of the present invention.

That is, the present invention relates to a cationized cyclodextrin represented by the following formula: The present invention provides a cleaning composition characterized in that it contains 0.5 to 50 weight percent of the anionic or amphoteric surfactant based on the total amount of the anionic or amphoteric surfactant.

Furthermore, the cationized/lilobquistri/ used in the present invention has the effect of clathrating various low-molecular organic compounds, and such clathrate compounds also have the effect of improving the feel of foam. Therefore, according to the present invention, it is possible to stably incorporate various low-molecular organic compounds into a detergent composition, and also to improve the feel of foam.

The cationized cyclodextrin used in the present invention is α, β
It is obtained by reacting a cyclodextrin such as , γ, etc. with a quaternizing agent such as glycidyltrimethylammonium chloride. Details of the synthesis method are available in Japanese Patent Application Laid-Open No. 58-21090.
It is described in Publication No. 1. This compound has significantly improved water solubility compared to its starting material, β-cyclodextyl IJ, etc., and can be incorporated in large amounts into detergent compositions, and also has good low-temperature stability. be. In particular, compared to cyclodextrin, clathrate compounds with other low-molecular-weight organic compounds have the property of being difficult to precipitate.

The cationized cyclodextrin used in the present invention is 0.5 to 50 weight tons based on the total amount of surfactants in the detergent composition.
Used in percentages. If the amount is less than this, the effect of improving the feel of the foam will not be sufficient, and if it is too much, foaming may be inhibited.
