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 detergency, and a creamy and good shape-retaining foam. It is an object of the present invention to provide a skin cleansing product.

[0006]

Means for Solving the Problems The present inventors have found that among sugar-based nonionic surfactants and anionic surfactants, a specific phosphate ester surfactant, sulfate ester surfactant or A detergent composition prepared by blending a sulfonic acid type surfactant is filled in a foam discharge container having a porous film, and the foam discharged from the container through the porous film,
The present inventors have completed the present invention by discovering that stains that were conventionally difficult to remove can be sufficiently washed with a good feeling of use.

That is, the present invention provides the following components (A) and (B) (A) a phosphoric acid ester type surfactant of the formula (1), a sulfate ester type surfactant of the formula (2) and a formula (3). ) At least one surfactant of sulfonic acid type surfactant

As can be seen from the results in Table 1, the skin cleansing articles of the examples showed very good results in detergency and foam quality. On the other hand, the skin cleansing article of Comparative Example was insufficient in detergency and foam quality because the surfactants of the components (A) and (B) were not used at the same time.

Example 4 A skin cleansing article was prepared as a face cleanser for makeup remover in the same manner as in Example 1 except that the components having the compositions shown in Table 2 were used. Next, a professional panel of 10 people washed the forearm coated with a water resistant foundation at a rate of 5 mg / 5 cm ² for 30 seconds with 0.1 g of foam discharged from the skin cleansing article, and the amount of the remaining water resistant foundation. When it was visually judged, it was possible to almost completely drop it.

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 amount of residual model sebum was visually inspected. As a result, it was almost completely dropped.

Comparative Examples 4 to 10 When the detergent compositions used in Examples 1 to 7 were used without being filled in a foam discharge container, all of them had insufficient foaming and were very easy to flow over the skin. Met. Therefore, sufficient detergency cannot be obtained.
