Problems solved by technology

[0003] However, higher fatty acid salts do not have sufficient foaming properties during washing and leave a tight feeling on the skin after washing
In addition, if the skin cleanser contains a higher fatty acid salt, there are problems in the storage stability of the formulation: precipitation of the higher fatty acid salt occurs during low-temperature storage; or the skin cleanser becomes hard; or separation occurs during high-temperature storage.

Embodiment 1～21、 comparative example 1～5

[0117] According to the formulations shown in Tables 1 to 6, the skin cleansers of Examples 1 to 21 and Comparative Examples 1 to 5 were prepared according to conventional methods.

[0118] In addition, in the table|surface, the unit of a numerical value is mass %, and "-" shows not blending.

[0119] For the prepared skin cleanser, according to the evaluation criteria described below, [1] foaming property, foam persistence, foam quality, [2] touch during cleansing, moisturizing feeling after washing, and [3] Preparation stability was evaluated. The evaluation results are shown in Tables 1 to 6.

[0120] In addition, the details of each component shown in Table 1 to Table 6 are as follows.

[0121] Microcrystalline cellulose; KG1000 is Ceolus KG1000: trade name, Asahi Kasei Chemicals Corporation, with an average particle diameter of 50 μm and a long-to-short-diameter ratio (L / D) of 3.5.

Abstract

The present invention provides a skin cleanser that is less irritating to the skin, has excellent foaming properties, has less tightness after washing, less contamination of containers due to stringiness during use, and exhibits good stability over time. The skin cleanser of the present invention contains microcrystalline cellulose with an average particle diameter of 100 μm or less, polyquaternium-7, higher fatty acid salts with 8 to 22 carbon atoms, and polyhydric alcohols.

Description

technical field [0001] The present invention relates to a skin cleanser. Background technique [0002] Higher fatty acid salts are often used in skin cleansers because of their excellent cleansing power and refreshing feeling of use. [0003] However, higher fatty acid salts have insufficient foaming properties during washing and leave a tight feeling on the skin after washing. In addition, if the skin cleanser contains a higher fatty acid salt, there are problems in the storage stability of the preparation such as precipitation of the higher fatty acid salt during low-temperature storage, hardening of the skin cleanser, or separation during high-temperature storage. [0004] In order to solve these problems, various studies have been conducted. [0005] For example, Japanese Patent Laid-Open No. Hei 3-227914 describes a liquid detergent composition in which foaming properties are improved by blending a cationic polymer and a glucose derivative into a higher fatty acid sal...
