Description

  The present invention relates to a skin cleanser.

  Various properties are required for skin cleansing agents such as facial cleansers, depending on the type and the needs of the user group. For example, it is necessary to have a feeling of degreasing that is a feeling that sebum has been removed after washing, a thing that has a weak feeling of degreasing and a mild washing, or a thing that feels moist after washing. Therefore, skin cleansing agents corresponding to the difference in these required properties have been developed.

  In addition, various types of skin cleansing agents are known, for example, solid skin cleansing agents such as soap bars, paste-like skin cleansing agents used by filling tube containers, and pump filling dispensers. Liquid skin cleansing agents; skin cleansing agents that are filled in aerosol containers or non-aerosol type pump former containers and used in the form of foams are known (for example, see Patent Document 1).

Japanese Patent Laying-Open No. 2015-78139

  In particular, the skin cleanser used by being discharged in the form of foam is required to have excellent discharge characteristics, high foamability when discharged, and the ability to form excellent foam quality. In order to satisfy such characteristics, a skin cleanser filled in a non-aerosol type pump former container generally has a relatively small content of surfactant.

  In such a skin cleanser with a low content of surfactant, it is difficult to stably add a fatliquor such as an oil. There was a problem that it was easy to cause a squeezing.

  The skin cleanser of the present invention is a skin cleanser that is discharged in the form of foam, and is preferably a pump former type skin cleanser that is used by being filled in a pump former container. The pump former container that can be used in the present invention is not particularly limited, and a commercially available pump former container may be mentioned. A skin cleanser product is obtained by filling the pump former container with the skin cleanser of the present invention. The skin cleanser product is a skin cleanser product comprising at least a pump former container and the skin cleanser of the present invention filled in the pump former container.

  The site to which the skin cleansing agent of the present invention is applied is not particularly limited, and includes the face (for example, forehead, eyes, eyes, cheeks, mouth, etc.), arms, elbows, back of hands, fingertips, feet, knees, heels, neck, Aside, back, scalp, etc. The skin cleansing agent of the present invention is preferably used as a facial cleanser, hand soap, and body soap because it suppresses squeak and tension while leaving a moderate degreasing feeling.

  The skin cleansing agent of the present invention can be produced by mixing the above-described components and stirring them using a known method such as a paddle mixer.

The present invention contains a relatively high amount of a higher fatty acid and / or a salt thereof (component A) as a cleaning composition. As a result, for example, when used as a skin cleanser filled in a non-aerosol type pump former container, it has excellent discharge properties, high foaming properties when discharged, and forms excellent foam quality Yes. Furthermore, it is excellent in a degreasing feeling.
However, in the case of a skin cleanser having a low surfactant content, it has been difficult to stably add a greasing agent such as an oil, and there has been a problem that squeaks and tension are likely to occur. Some skin cleansing agents are required to have a proper degreasing feeling, and it has been difficult to suppress squeaks and tension after rinsing in such skin cleansing agents.
In contrast, in the present invention, a polyhydric alcohol (component C) is blended in addition to component A as a component that exhibits a degreasing feeling, and (eicosandioic acid / tetradecanedioic acid) polyglyceryl (component B) is mixed with component A. By mixing at a specific ratio, squeak and squeezing after rinsing were suppressed while leaving an appropriate degreasing feeling.

(Degreasing feeling)
A pump former was filled and used for evaluation. About 1 g of the skin cleanser was discharged from the pump former to the inner side of the forearm, and was applied by hand. Immediately after rinsing with lukewarm water, the washed part was touched with fingers in the wet state, and the touch was evaluated according to the following criteria.

◎ (Very good): There is no sliminess, and there is a feeling of resistance that is caught on the finger.
