Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning composition, more specifically a cleaning composition containing a phosphate ester surfactant and a taurine surfactant, which has excellent foaming power, rapid foaming properties, and cleaning power. This invention relates to a cleansing composition that is gentle on the skin.

Recently, phosphate ester surfactants, which are a type of ionic surfactants, have been recognized as extremely mild surfactants with low irritation to the skin, and have been used as a component of cleaning compositions. It's being used. However, this phosphate ester surfactant has several drawbacks, including poor foaming properties, particularly rapid foaming, which is an essential performance required for cleaning compositions. It has not yet been satisfactory as a surfactant for compositions. For this reason,
There has been a desire to improve the performance of cleaning compositions containing phosphate ester surfactants while taking advantage of their properties.

The present inventors conducted intensive research on cleaning compositions using phosphate ester surfactants in order to eliminate the above-mentioned drawbacks. The present invention was completed based on the finding that the combination of a surfactant improves the shortcomings of the cleaning composition, such as the lack of rapid foaming properties, and does not change the characteristic of low irritation to the skin.

Next, the present invention will be described in more detail with reference to Examples, but the present invention 8A is not limited to these Examples.

Example 1 Liquid detergent A liquid detergent was prepared with the following composition, and the foaming power was measured by varying the type and blending ratio of the phosphate ester surfactant and taurine surfactant.

The results are shown in Table 1.

Composition: Ethanol 10-Water
Conditions and method for measuring residual foaming power: Prepare a 15% aqueous solution of the sample detergent, and
into a graduated cylinder. Next, a stirring blade was placed in the solution, and while the blade was reversed every 5 seconds, the stirring blade was stirred for 60 minutes.
The mixture was stirred for a second to generate bubbles, and the volume of the bubbles generated was measured.

As is clear from Table 1 below, a detergent with excellent foaming power can be obtained by combining a phosphate ester surfactant and a taurine surfactant.
