Description

  The present invention relates to an aqueous cosmetic containing titanium oxide and an acid dye. More specifically, the titanium oxide is excellent in stability of sedimentation over time and hard to form a hard cake even when the titanium oxide is precipitated. The present invention relates to a water-based cosmetic that is redispersible and that is suitable for nail art and other nail arts excellent in usability and application performance, and for skin coloring.

Conventionally, many water-based cosmetics containing titanium oxide having excellent hiding power have been known.
The titanium oxide contained in the aqueous cosmetic will settle and form a hard cake when left standing for a long time. This hard cake has a problem that redispersion by stirring or the like is not easy.

  Conventionally, as a skin coloring cosmetic with good pigment dispersibility during storage, at least water, a pigment containing titanium oxide, a skin coloring cosmetic containing a resin, and a styrene-acrylic acid copolymer as a resin, Contains at least one resin selected from the group consisting of a styrene-maleic acid copolymer, a styrene-alkyl acrylate copolymer, and a styrene-alkyl maleate copolymer, and a base such as ammonia or amines, and further a clay type Skin coloring cosmetics comprising at least one thickener selected from inorganic thickeners, inorganic fine particle thickeners, and polysaccharide thickeners (see, for example, Patent Document 1 of the present applicant) are known. ing.

  In addition, a water-based nail polish that improves dispersibility by blending a powder obtained by hydrophilizing a powder such as titanium oxide with a silylating agent having a polyoxyethylene chain and an acrylic polymer emulsion ( For example, see Patent Document 2).

However, even in aqueous cosmetics such as skin coloring cosmetics and water-based beauty nails described in Patent Documents 1 and 2, they may settle and form a hard cake when left still for a long time. At present, re-dispersion by stirring or the like is not easy.
Furthermore, in the aqueous cosmetic containing titanium oxide, when an acidic dye is present, aggregation of titanium oxide is likely to occur, and when sodium polyaspartate is used as a dispersant for titanium oxide as a dispersant, Over time, there are problems such as causing aggregation and an increase in viscosity. For this reason, there is a problem that it cannot be accommodated in a pen-type applicator.

In the present invention, by including an alkali-soluble acrylic resin as a dispersing agent such as titanium oxide, conventionally, when an acid dye is present, sodium polyaspartate is used as a dispersing agent for titanium oxide. In addition, it exhibits superior dispersion performance compared to the case of using styrene-acrylic resin or the like. This is presumably because a soft cake can be formed by the absence of a styrene group.
Furthermore, in the present invention, even when a water-based cosmetic containing titanium oxide and an acid dye is accommodated in a pen-type applicator described later, the titanium oxide does not aggregate and solidify, and the Since an increase in viscosity can be suppressed, an aqueous cosmetic can be obtained that can be suitably used for an unprecedented pen-type applicator.

However, the side of the coated body is further opened by cutting a side of the tubular inner cylinder by cutting or the like. It is also possible to form. By adopting such a configuration, it is possible to secure a flow path when clogging occurs due to the titanium oxide or the pigment, and there is an accident such as an increase in the viscosity of the aqueous cosmetic due to water evaporation or the like. Even when it happens, the water-based cosmetic can flow in without any delay.

By using the water-based cosmetic-applied applicator B having this structure, the water-based cosmetic having the above characteristics can be smoothly and efficiently supplied to the application body. And, for example, when the excessive amount of the aqueous cosmetic flows out due to the opening of the valve mechanism 16 more than necessary in FIG. 1, the excessive amount is temporarily held by the open-cell porous body 19. Thus, it is possible to prevent the dropping from the application body 20.
