Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a skin cleansing article in which a cleansing composition is filled in a foam discharge container. More specifically, the present invention relates to a skin cleansing article which has a good feeling of use, has a high cleansing power, and discharges foam that is creamy and has good shape retention.

[0002]

2. Description of the Related Art Conventionally, foaming detergent compositions for use in the form of foam discharged from a foam discharge container have been developed for various uses such as bath, face wash and hair wash. As a foam discharge container for filling with such a foamable cleaning composition, various devices have been devised in order to discharge stable foam. For example, a container (Japanese Examined Patent Publication No. 52-16567) that discharges in the form of bubbles by mixing a detergent composition with air and passing it through a bubble generating means such as a porous body is known.

Further, as a foaming detergent composition for ejecting fine bubbles from such a foam ejection container, there has been proposed a composition containing a surfactant, a monohydric alcohol and a polyhydric alcohol (Japanese Patent Laid-Open No. Hei 5 (1999) -58242). -132700). Also,
To reduce skin irritation, maintain a constant surfactant concentration on the skin for a long time, and cleanse the skin with good reproducibility, use a relatively low concentration of a hypoallergenic surfactant and a water-soluble polymer. It has also been proposed to fill the squeeze foamer container with the detergent composition contained therein and use it (see Table 5).
No. 506259).

[0004]

However, the conventional detergent composition filled in the foam discharge container has a problem that the foam density is high and the shape retention is insufficient. Therefore, when massaging the skin with the foam discharged from the foam discharge container, there is a problem that the foam disappears during the massage, and a sufficient feeling of massage cannot be obtained. There was also a problem. This problem was particularly noticeable in the case of cleaning makeup products that are difficult to remove even with sweat, and hair cosmetics with a high setting power that contain a polymer having a relatively low solubility in water.

The present invention is intended to solve the problems of the prior art as described above, and has a good feeling of use, a high cleaning power, and a creamy and good shape-retaining foam discharge. It is an object of the present invention to provide a skin cleansing product.

Example 5 A skin cleansing article was prepared as a face wash in the same manner as in Example 1 except that the components having the composition shown in Table 3 were used. Next, with 10 professional panelists, with 0.1 g of foam discharged from the skin cleansing article, the forearm coated with model sebum at a rate of 10 mg / 5 cm ² was massaged for 30 seconds, and the degree of residual model sebum was visually inspected. As a result, it could be washed off almost completely, and almost no residue remained.

EFFECTS OF THE INVENTION According to the skin cleansing article of the present invention, a homogeneous and creamy foam with low irritation and high cleansing power can be obtained. By using the foam, oily stains that are difficult to remove, such as lipstick, eye makeup, and water resistant foundation, can be well washed with a good feeling of use. It can also be used favorably as a shampoo and body wash.
