Aqueous cosmetic

Abstract

Disclosed is an acidic dye-based aqueous cosmetic preparation containing titanium oxide and an acidic dye or an organic pigment-based aqueous cosmetic preparation containing titanium oxide and an organic pigment, wherein titanium oxide sedimentation stability over time is excellent, a hard cake is not easily formed even when titanium oxide has sedimented, and the sedimented titanium oxide can be easily re-dispersed by stirring. The aqueous cosmetic preparations of respective compositions have excellent usability and coating properties, and are suitable for nail beauty preparations for nail art, products for skin coloring or the like. The aqueous cosmetic preparations are configured to contain at least 5-30% by mass of titanium oxide, an acidic dye or an organic pigment, an alkali-soluble acrylic resin and water.

Description

technical field [0001] The present invention relates to an aqueous cosmetic comprising titanium oxide and an acid dye or an organic pigment, and more particularly to an aqueous cosmetic whose titanium oxide is excellent in aging settling stability so that even when oxidized Titanium also does not easily generate hard cake when it settles and can be easily redispersed by stirring, it is excellent in workability and applicability and is suitable for manicure compositions for manicures, cosmetics for skin coloring, and the like. Background technique [0002] Many cosmetics have been known so far as water-based cosmetics containing titanium oxide excellent in covering power. [0003] Titanium oxide contained in the above-mentioned aqueous cosmetics settles to form a hard cake when left for a long time. This hard cake involves the problem that it is not easily redispersible by stirring or the like. [0004] Cosmetics for skin coloring comprising at least water, a pigment contai...

AI Technical Summary

Problems solved by technology

[0006] However, also in aqueous cosmetics such as the aqueous cosmetics for skin coloring and the aqueous manicure compositions described in each of the aforementioned Patent Documents 1 and 2, the current situation is that the components settle to form a hard cake in certain cases when left standing for a long time , and it is not easy to redisperse them by stirring etc.

[0007] In addition, there are problems involved in that when an acid dye is present in an aqueous cosmetic containing titanium oxide, it tends to cause aggregation of titanium oxide, and when sodium polyaspartate is used as a dispersant for titanium oxide, the come together to increase the viscosity

Therefore, therein lies the problem that they cannot be accommodated and used in pen-type applicators

[0008] In addition, when an aqueous cosmetic containing titanium oxide is accommodated in a pen applicator, its tip is dry, and therefore therein involves a problem that, particularly in the case of an aqueous cosmetic in which titanium oxide is blended with an organic pigment, the above-mentioned organic pigment Agglomerates and solidifies, whereby the cake becomes harder
