Embodiment

[0101] Hereinafter, although an Example is shown and this invention is demonstrated more concretely, this invention is not limited to these Examples.

[0102] [Reference test example]

[0103] Liquid compositions for skin cleansing having the compositions shown in Tables 1 to 4 were prepared. Details of each component shown in Tables 1 to 4 are as follows. It should be noted that the liquid compositions for skin cleansing shown in Tables 1 to 4 are liquid, and the viscosity at 20° C. (measured by BL viscometer (B-type viscometer manufactured by Brookfield Co., Ltd.) spindle No. 3, 6 rpm) is all 5000 mPa·s The following ranges, except for Reference Example 1 (pH at 25° C. about 10), the pH at 25° C. is within the range of 3 to 8.

Abstract

The purpose of the present invention is to provide a liquid composition for skin cleansing, which is used in a non-conventional method. The liquid composition for skin cleansing according to the present invention, which contains (A) a surfactant and (B) an amphiphilic ester and has a pH of from 3 to 8, while being contained in a spray container, is capable of exhibiting excellent cleansing power,while being reduced in the skin irritancy of the liquid composition for skin cleansing, and is able to provide a novel use that is different from conventional uses wherein a liquid composition for skin cleansing is foamed before application to the skin, said novel use being direct spraying of a liquid composition for skin cleansing onto the skin.

Description

technical field [0001] The present invention relates to a liquid composition for skin cleansing capable of cleansing without applying physical friction to the skin. Background technique [0002] Various skin cleansing compositions such as facial cleansers, body soaps, and shampoos are offered as products aimed at cleansing and keeping the skin clean. In the mechanism of skin cleansing by the skin cleansing composition, the surface active agent is adsorbed on the dirt to reduce the surface tension between the dirt and water, and the mechanical force generated by friction also interacts to make the dirt float in the water . In order for such a cleaning mechanism to function effectively, it is necessary to mix a surfactant at a critical micelle concentration or higher. [0003] On the other hand, the cleaning power of the surfactant is too strong, causing skin irritation, and as a result, skin problems such as dry skin are caused. Therefore, for the purpose of softening the ...
