Description

  The present invention relates to a cleaning composition containing charcoal, polyoxypropylene coconut oil fatty acid monoisopropanolamide and a polyhydric alcohol having an IOB value of 3 to 5, more specifically, excellent in the dispersion stability of charcoal, The present invention relates to a detergent composition that can easily remove pores and provide a moist feeling after use.

  The detergent composition is a preparation containing various components in combination for the purpose of removing dirt and excess sebum on the skin. Conventionally, as a method for increasing the cleaning power, the content of cleaning components such as a surfactant is increased, or the scrubbing agent or powder is included to cause friction with the skin and physically remove dirt. A method of facilitating has been used. As an example, there is a technique using charcoal as a powder. Since charcoal is porous and has sebum adsorbing ability, it has been developed that contains it in a cleaning agent to enhance its cleaning ability. As a technique containing charcoal, for example, there is a technique containing a higher fatty acid, charcoal and a polyhydric alcohol (see, for example, Patent Document 1). Moreover, there exists a technique containing charcoal and an alkyl acrylate copolymer (for example, refer patent document 2).

JP 2002-167325 A Japanese Patent Application Laid-Open No. 2002-212060

Among the prior arts described above, in the technique of Patent Document 1, the stability of the cleaning agent itself may be impaired or foaming may be deteriorated depending on the degree of polymerization of polyethylene glycol. Further, in the technique of Patent Document 2, there is a case where a film feeling and a feeling of tension unique to a polymer are observed after use. Further, in the conventional detergent technology, increasing the cleaning power, on the other hand, sometimes caused a feeling of irritation during use or a feeling of tension after use by removing sebum more than necessary.
In addition, in the conventional technology, the viscosity of the cleaning composition decreases when the cleaning composition is stored at a high temperature, so that charcoal may settle, and even when the cleaning composition is returned to room temperature, the structure of the cleaning composition is In some cases, the appearance of the preparation becomes non-uniform, for example, the charcoal contained becomes localized due to non-uniformity.
Therefore, in the present invention, technological development was conducted with the aim of a detergent composition that has excellent charcoal dispersion stability, good soil removal, and a moist feeling after use.

  In view of this situation, the present inventor has intensively studied, and as a result, has found that a material called charcoal is useful as a material that achieves both improvement in detergency and a moist feeling after use. However, when charcoal is included in the cleaning composition, it is necessary to coexist with a specific surfactant in order to stably contain this charcoal in the preparation, such as sedimentation with time. Thought. As a result of various investigations, in order to disperse the charcoal, the polyoxypropylene coconut oil fatty acid monoisopropanolamide and the polyhydric alcohol having a specific IOB value are included, so that the charcoal settles even at high temperatures. In addition, the present inventors have found that the appearance does not become uneven even when the temperature is returned from high temperature to room temperature.

That is, the present invention includes the following components (a) to (c);
(A) Charcoal (b) Polyoxypropylene coconut oil fatty acid monoisopropanolamide (c) The present invention relates to a cleaning composition comprising a polyhydric alcohol having an IOB value of 3 to 5.

  The average particle diameter of a component (a) is 1-200 micrometers, It is related with the cleaning composition characterized by the above-mentioned.

  The component (b) has an average number of polyoxypropylenes of 0.3 to 5 mol per molecule, and relates to a detergent composition.

  The cleaning component of the cleaning composition is a higher fatty acid salt.

  Furthermore, the present invention relates to a cleaning composition comprising polyethylene glycol having a number average molecular weight of 1,000 to 6,000 as component (d).

As another aspect of the present invention, the cleaning is characterized in that the mass ratio of the component (a) and the component (b) is in the range of (a) :( b) = 5: 1 to 1: 100 It is related with an agent composition.
By making it within the range of such a ratio, it is possible to further improve the dispersion stability of charcoal in the cleaning composition.

  Furthermore, as another aspect of the present invention, it is possible to provide a cleaning composition containing the component (a) charcoal in granulated granules. By containing charcoal in granulated granules, it acts synergistically with the sebum adsorption effect of charcoal when the detergent composition contains charcoal alone and the effect of removing pores as granulated granules. It is also possible.

The cleaning composition of the present invention has the advantages of being excellent in the dispersion stability of charcoal, having good dirt removal from pores, and having a moist feeling after use.
The component (a) charcoal used in the cleaning composition of the present invention is porous and has the property of adsorbing excess sebum on the skin.
