Description

Skin cleanser composition

The present invention relates to a skin cleanser composition.

Conventionally, as a skin cleanser that more reliably removes dirt, which is difficult to remove with a conventional skin cleanser, as a metabolite such as old dead skin cells or sebum of the skin, peeling cleanser and cleanser containing a scrub agent have been known.

For example, Patent Document 1 discloses a cleaning cosmetic containing specific porous silica particles as a scrub agent. According to this cosmetic for washing, it is described that even if rubbed with a weak application force, a sufficient scrub feeling is obtained, and a burning feeling is suppressed.

Further, for example, Patent Document 2 discloses a peeling cosmetic containing polyvinyl alcohol in the water-resistant phase. According to this peeling cosmetic, it is described that it has an excellent cleaning effect to remove impurities from the skin and adhered dirt, has a good feeling of use, and also has little irritation to the skin.

The skin cleanser composition of the present invention is not particularly limited, and can be produced by a known or common method. For example, it can be prepared by mixing each of the above components and using an emulsifying kiln.

The skin cleanser composition of the present invention is a composition used for washing by applying it to the skin (skin). The skin cleanser composition of the present invention is not particularly limited, and includes, for example, the face (e.g., forehead, around the eyes, the tail of the eyes, cheeks, around the mouth, etc.), arms, elbows, back of hands, fingertips, and legs. , Knees, heels, neck, armpits, and back. Among them, the skin cleanser composition of the present invention is preferably for face use from the viewpoint of having a small burden on the skin, although it has the same cleanability as a conventional scrub-containing cleanser or peeling cleanser.

The skin cleanser composition of the present invention can be used as a face wash, body soap, hand soap, or the like. Especially, it is preferable that it is a face wash.

The skin cleanser composition of the present invention can be applied to various formulations and is not particularly limited, but it is preferably in the form of a cream or an emulsion. When the component (B1) is included, the skin cleanser composition of the present invention can exhibit a creamy formulation without causing agglomeration of the component (B1). In addition, when the component (B2) is included, the easiness of foaming becomes particularly good when the skin cleanser composition of the present invention is in the form of a cream or an emulsion. Further, the skin cleanser composition of the present invention may be in the form of the skin cleanser composition of the present invention filled in a container. Examples of the container include a pump container and a tube container.

In the composition for the skin cleanser of the present invention, in a composition containing water [component (D)] as a medium, higher fatty acids and/or salts thereof [component (A)] are used in a specific ratio, and fibrous cellulose [component (B1)] )] in a specific ratio, the component (B1) is uniformly dispersed without agglomeration, so that the burden on the skin at the time of washing is small, and the conventional scrubbing agent-containing detergent is not used even if a scrub agent is not used. It is possible to have the same cleaning properties as the peeling detergent. In addition, when using degreasing rice bran [component (B2)] in combination in a specific ratio, it is estimated that the shape of the component (B2) or what has been "degreased" greatly affects it, and the scrub feel and the grind The feeling is suppressed, the burden on the skin is small, and even without using a scrub agent or the like, it is possible to have cleaning properties equivalent to those of conventional scrubbing agent-containing detergents and peeling detergents. Further, by blending the cationic polymer (component (C)) in a specific ratio, a polymer film is formed on the skin after washing the skin and covers the skin, thereby providing excellent smoothness.

[Table 2]

When using the skin cleanser composition of the present invention containing the component (B2) as the component (B) (Examples 4 to 8), it has the same cleanability as the conventional scrub-containing cleanser or peeling cleanser, and the land after cleansing It was evaluated that the burden on the skin was small because a feeling of creeping and scrubbing during washing were not felt. In addition, it was evaluated that the smoothness of the skin after washing was excellent, and foam generation and foam quality were also excellent. On the other hand, when the component (B2) was not blended (Comparative Example 3), it was evaluated that the cleaning power was inferior to that of the scrubbing agent-containing detergent or the peeling detergent. In addition, when the content ratio of the component (B2) was large (Comparative Example 4), a feeling of greasyness after washing was felt, and it was evaluated that the burden on the skin was large. In addition, in the case of using a material predicted to exhibit the same effect as the component (B2) instead of the component (B2) (Comparative Examples 5 to 8), a scrub feeling during washing was felt, and it was evaluated that the burden on the skin was large.
