Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keratin plug removing agent which can satisfactorily remove keratin plugs formed in pores.

[0002]

2. Description of the Related Art Conspicuous pores are one of the top problems in women's skin troubles recently, which is one of the top problems. This is largely due to the horn plug formed in the pores. The keratin plug is keratinized together with sebum and contains keratin and is clogged in the pores. If left unattended, not only the pores are conspicuous but also various skin problems occur. Therefore, it is preferable to remove the keratin plug from the viewpoint of beauty and skin health.

However, the keratin plug cannot be sufficiently removed by the commonly used face wash and makeup remover. On the other hand, peel-off type pack agents are applied on the skin, dried and then peeled off from the skin. As film-forming agents used therefor, polyvinyl alcohol, polyvinyl pyrrolidone and the like are used. However, those containing these nonionic polymers as the main components are not sufficient for removing stains on the pores that are difficult to remove, and show little effect particularly for removing horn plugs.

Therefore, a keratin plug removing agent that can effectively remove keratin plugs has been desired.

[0005]

In view of the above circumstances, the inventors of the present invention have conducted diligent research and as a result, found that a keratin plug removing agent containing a polymer compound having a salt-forming group and an oil agent hurt the skin. The present invention has been completed based on the finding that keratin plugs and stains can be effectively removed without any problems.

That is, the present invention provides a keratin plug remover characterized by containing a polymer compound having a salt-forming group and an oil agent.

The salt-forming group of the polymer compound used in the present invention is not particularly limited as long as it is a group that forms a salt in the presence of an acid or a base, and any of anionic, cationic and zwitterionic groups can be used. May be Specific examples of such a salt-forming group include a carboxyl group, a sulfonic acid residue, a sulfuric acid residue, a phosphoric acid residue, a nitric acid residue, an amino group and an ammonium group. Two or more kinds of these groups may be contained in one compound.
