Embodiment 1～32

[0059] Examples 1-32, Comparative Examples 1-13

[0060] The skin cleansing compositions with the compositions shown in Tables 1 to 9 were produced, and the speed until the feeling of a pause was felt during rinsing, the strength of the pause feeling at the end of rinsing, the refreshing feeling after drying with a towel, and the amount of bubbles were evaluated. . In addition, in some of the examples, the smoothness after drying, pearly luster, foam breaking, and liquid appearance were also evaluated. Finally, the results are combined and shown in Table 1 to Table 9 respectively.

[0061] Production method

[0062] The ingredients shown in the table were weighed and added to ion-exchanged water, and stirred sufficiently at a temperature of 50°C to obtain a skin cleansing composition. Add an appropriate amount of sodium hydroxide or malic acid to adjust the pH of the 20-fold dilution to weak acidity. Here, the pH was measured using a pH meter (manufactured by HORIBA, model...

Abstract

A skin cleansing composition contains the following ingredients (A), (B) and (C): (A) a polyoxyethylene alkylether sulfate, (B) a polyoxyethylene alkylether carboxylate, and (C) a cationic group-containing polymer having a cationic charge density of not less than 4.5 meq/g, and/or polyvinylpyrrolidone. A weight ratio (A):(B) of the ingredient (A) to the ingredient (B) is from 85:15 to 25:75. A total content of the ingredients (A) and (B) based on the whole composition ranges from 5 to 25 wt %. A content of the ingredient (C) ranges from 0.05 to 1 wt %. The skin cleansing composition is excellent in foamability and foam quality, and provides a good stop feeling during rinsing and a refreshed touch feeling after towel blotting.

Description

technical field [0001] This invention relates to skin cleanser compositions. Background technique [0002] Among the performances of a skin cleanser for face and body cleansing, it is important that a feeling of touch (stop feeling) with frictional resistance appear as a feeling at the time of rinsing during use. When rinsing, it takes a short time until the feeling of stopping is felt, and when the strength is strong, it is preferable because a refreshing feeling can be provided. [0003] In the prior art, in the skin cleansing composition with surfactant widely used in this field, that is, polyoxyethylene alkyl ether sulfate as the main agent, although its foaming property is good, there are residues when rinsing The slimy feeling problem. In Patent Documents 1 and 2, it is described that, in a personal cleansing composition containing a water-soluble surfactant such as polyoxyethylene alkyl ether sulfate as a main ingredient, by adding a water-insoluble surfactant such ...
