Among them, isopropylmethylphenol and salicylic acid are preferable, and isopropylmethylphenol is more preferable. The bactericide may be used alone or in combination of two or more.

The pH of the skin cleansing composition of the present invention is preferably 9.0 to 11.0, more preferably 9.0 to 10.0. When the pH is within the above range, the load on the skin during washing can be further reduced.

The skin cleansing composition of the present invention is not particularly limited, and can be manufactured by a known or commonly used method. For example, it can be produced by mixing the above components and using an emulsifying pot.

The skin cleansing composition of the present invention is a composition used for applying and cleaning the skin (skin). The site where the skin cleansing composition of the present invention is used is not particularly limited, and includes, for example, the face (for example, forehead, eyes, eyes, cheeks, mouth, etc.), arm, elbow, back of hand, fingertip, foot, knee. , Heel, neck, armpit, back, etc. Among them, the skin cleansing composition of the present invention is preferably for facial use from the viewpoint of having a small burden on the skin, although it has the same cleanability as conventional cleansing agents containing scrubbing agents and peeling cleansing agents.

The skin cleansing composition of the present invention can be used as a facial cleanser, body soap, hand soap and the like. Of these, a face wash is preferable.

The skin cleansing composition of the present invention can be applied to various dosage forms and is not particularly limited, but it is preferably a cream or emulsion. When the component (B1) is included, the skin cleansing composition of the present invention can exhibit a creamy dosage form without causing aggregation of the component (B1). In addition, when the skin cleansing composition of the present invention is in the form of a cream or an emulsion when it contains the component (B2), the foamability is particularly good. The skin cleansing composition of the present invention may be in the form of the skin cleansing composition of the present invention filled in a container. Examples of the container include a pump container and a tube container.

The skin cleansing composition of the present invention uses a higher fatty acid and / or its salt [component (A)] in a specific ratio in a composition using water [component (D)] as a medium, and uses fibrous cellulose [component]. When (B1)] is used in combination at a specific ratio, the component (B1) is uniformly dispersed without aggregating, the burden on the skin at the time of washing is small, and a conventional scrub agent is not used. It is possible to have a cleaning property equivalent to that of a cleaning agent containing a scrubbing agent or a peeling cleaning agent. When the defatted rice bran [ingredient (B2)] is used in combination at a specific ratio, it is presumed that the shape of the ingredient (B2) and the “defatted” one have a great influence on the feeling of scrubbing. The tautness is suppressed, the burden on the skin is small, and it is possible to have the same cleanability as a conventional cleaning agent containing a scrubbing agent or a peeling cleaning agent without using a scrubbing agent or the like. Then, by blending the cationic polymer [component (C)] in a specific ratio, a polymer film is formed on the skin after washing the skin, and the skin is covered, whereby the smoothness is excellent.

Hereinafter, the present invention will be described in more detail based on Examples, but the present invention is not limited to these Examples. The blending amount shown in the table is the blending amount of each component (that is, the blending amount of the active ingredient in each raw material, so-called pure content), and is represented by "mass%" unless otherwise specified. Further, potassium hydroxide was added so that the pH would be 10.0.
