Abstract

<P>PROBLEM TO BE SOLVED: To provide a water-based skin care preparation containing a dye and markedly improved in the fading, deterioration or the like of the dye. <P>SOLUTION: The water-based skin care preparation contains the dye and has a pH of ≥7, especially 7-10. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an aqueous external preparation, an aqueous external preparation composition, and a makeup remover using the same, which are external preparations having a dye and are free from discoloration and discoloration of the dye.

Technical background

  Conventionally, external preparations for skin, such as cosmetics, having various pigments are known. This is widely adopted because it appeals visually to the purchase and use of the user. Furthermore, lip, teak, eye color, and the like are also used for those originally intended to apply a pigment to the surface of the skin.

  Therefore, various skin dyeing agents have been studied. For example, Patent Document 1 includes (A) one or two or more types of adhesives, and (B) one or more types selected from the group consisting of alcohols, ethylene glycol alkyl ethers, and N-alkylpyrrolidones, (C) It has disclosed about the skin dyeing | staining composition characterized by containing dye and pH being 1.5-6 (patent document 1).

  However, as a result of studies by the inventor, it was found that when the pH is low, fading of the dye is observed. In particular, the deterioration of a product placed in a transparent bottle and placed in a store for a long period of time is remarkable.

  On the other hand, since the surface of the skin is weakly acidic, cosmetics that have been weakly acidic have been mainly used.
