Description

  The present invention relates to a sesame cosmetic used by mixing at the time of use, and more specifically, has a skin cleansing effect, a short time required for rubbing, a dullness improving effect, a refreshing feeling of use, and a simple treatment. It relates to cosmetics with excellent properties.

  Gommage cosmetics apply cosmetics on the skin, and then apply physical external force (massage) such as massage with fingers or instruments to make up old keratin and dirt. It is a cosmetic intended to be scraped off together with the material. This is because agglomerates of cosmetics such as debris generated by rubbing adsorb skin keratin and dirt. For this reason, it is necessary to add to the gorge cosmetics a gorge agent that easily adsorbs to the skin's keratin and dirt, and produces aggregates such as debris. Conventionally, powder, crystalline cellulose, film-forming properties are required. Water-soluble polymers, solid paraffin, and the like have been proposed as sesame agents (see, for example, Patent Documents 1 to 3). However, in sesame cosmetics containing powder, it takes time to obtain the gamage effect until the debris is generated, so that the skin is subjected to a strong load due to physical external force and the skin is excessively burdened. there were. In addition, in the case of using a film-forming water-soluble polymer or solid paraffin, debris tends to remain on the skin after the treatment, and an action such as wiping off and removing the gommage agent occurs. There was a problem such as not being able to get.

On the other hand, ascorbic acid has been conventionally used in cosmetics as an effective component for whitening. Ascorbic acid has the disadvantage of being easily oxidized and chemically unstable,
Various ascorbic acid derivatives have been used in cosmetics, and these have also been used in detergents containing anionic surfactants (see, for example, Patent Documents 4 and 5). However, in detergents that contain an anionic surfactant that is an alkali metal salt, even when an ascorbic acid derivative that is more stable than ascorbic acid is blended, the storage stability of cosmetics may deteriorate. there were. For this reason, the cosmetics which provided the whitening effect by an ascorbic acid derivative to the cosmetics which mix | blended the anionic surfactant which is an alkali metal salt were calculated | required.
