Abstract

A skin cleansing composition comprising 5.0 to 50 mass% of a higher fatty acid and/or a salt thereof, 1.0 to 10 mass% of silica, 0.1 to 4.0 mass% of a cationic polymer, and 0.5 to 10 mass% of a sugar alcohol.

Description

Skin cleanser composition

Technical Field

The present invention relates to a skin cleansing composition for cleansing the skin and a skin cleansing agent obtained by filling a container with the composition.

Background

The detergent composition using a fatty acid salt is preferred because of its good detergency to sebum dirt and good feeling of cleanness after washing, but foaming power and foam accumulation during foaming are in room for improvement. Therefore, the following techniques are proposed: other surfactants and water-soluble polymers are added to a detergent composition using a fatty acid salt to increase the film strength of the foam, thereby increasing the foaming power and the foam volume (patent documents 1 and 2).

Problems to be solved by the invention

However, the detergent composition having the foaming power and the bubble volume increased by the above method has the following problems: a phenomenon known as stringing occurs when the composition is spread; the rinsing property after cleaning becomes poor.

The invention aims to provide a skin cleansing composition which has good foaming power and foam volume when foaming and improved rinsing performance after cleansing.

Means for solving the problems

The present inventors have conducted intensive studies and as a result, have found that a skin cleansing composition excellent in foaming power and foam volume at the time of foaming and in rinsing performance after cleansing can be obtained by blending silica, a cationic polymer and a sugar alcohol in a cleansing composition using a fatty acid salt, and have completed the present invention.

The higher fatty acid and/or salt thereof contained in the skin cleanser composition of the present embodiment may be appropriately selected and used according to the properties of the skin cleanser composition and the like.

In the present specification, the term "higher fatty acid" refers to a linear or branched saturated or unsaturated higher fatty acid. The higher fatty acid preferably has 10 or more carbon atoms, more preferably 12 or more carbon atoms, from the viewpoint of ensuring the viscosity and cleansing power of the skin cleansing composition. In addition, from the viewpoint of preventing water fusion and deterioration of high-temperature stability of the skin cleansing composition, it is preferably 20 or less, more preferably 18 or less. In addition, it is preferable that the fatty acid contains 12 to 14 carbon atoms in order to further improve foaming and foam quality.

Specific examples of the higher fatty acid include lauric acid, tridecylic acid, myristic acid, pentadecanoic acid, palmitic acid, heptadecanoic acid, stearic acid, arachidic acid, behenic acid, isooctanoic acid, isononanoic acid, isodecanoic acid, isoundecanoic acid, isolauric acid, isotridecanoic acid, isomyristic acid, isopentadecanoic acid, isopalmitic acid, isoheptadecanoic acid, isostearic acid, isononanoic acid, isononadecanoic acid, isoarachidic acid, isoheneicosanoic acid, and isobehenic acid. Other specific examples of the higher fatty acid include: vegetable oils such as olive oil, coconut oil, palm oil, and cottonseed oil; animal fat such as fish oil and beef tallow.

In the present specification, the term "higher fatty acid salt" refers to a compound obtained by saponifying or neutralizing at least a part (a part or all) of the higher fatty acid with an alkaline agent. In the case of using a higher fatty acid salt, the higher fatty acid salt can be obtained from a higher fatty acid and an alkaline reagent and then mixed with other components; the higher fatty acid salt may be prepared in the composition by compounding a higher fatty acid with an alkaline agent. It should be noted that such a higher fatty acid salt is also referred to as a higher fatty acid soap.

The alkaline agent can be used as a neutralizing agent. Examples of the base include inorganic bases such as sodium hydroxide, potassium hydroxide, sodium carbonate, and potassium carbonate; organic bases such as monoethanolamine, diethanolamine, triethanolamine, trimethylamine, triethylamine, isopropanolamine, morpholine, and arginine. Sodium hydroxide, potassium hydroxide, and triethanolamine are preferred because they are easily obtained and have excellent handling properties.

The higher fatty acid and/or salt thereof preferably includes a straight-chain higher fatty acid and/or salt thereof, from the viewpoint of further improving foaming. On the other hand, the composition may contain a branched higher fatty acid and/or a salt thereof in order to further improve the foaming property and the stability of the composition.
