JP4299294B2 - Water-based eyeliner composition - Google Patents

Description

  The present invention relates to a water-based eyeliner composition that is excellent in friction resistance, has a vivid color and smooth writing, and has good storage stability.

  Conventionally, eyeliners have been applied around the eyes and used to enhance the impression of the eyes, but in recent years their uses have diversified, and they are not only black with a high effect of making the eyes appear larger, but also have a glittering effect. There is a tendency to increase the number of blends of high pearl pigments and lame agents, and high fashionability is required.

  However, the conventional eyeliner has a very large particle size of the pearl pigment and the lame agent, so there is a problem that the brush pen type is clogged with the gap between the fibers of the brush, and other than the brush pen type. However, in a low-viscosity composition such as an eyeliner, these precipitate with time, and it is difficult to blend a large amount of glitter pigment.

  On the other hand, for the purpose of producing blackness, efforts have been made to blend carbon black, which has higher coloring power than black iron oxide, etc., but due to its strong cohesion, it is not uniformly dispersed in the system, There was a problem that the blackness of the coating film was uneven, and in addition, it was very difficult to obtain good storage stability.

  In order to solve these problems, a liquid cosmetic production method is disclosed in which a slurry in which water, barium sulfate and sodium phosphate are mixed is prepared in advance and then mixed with a polymer and a pigment (Patent Document 1). reference). However, in the present invention, since an extender pigment such as barium sulfate is blended, the composition becomes cloudy and a vivid color cannot be obtained, and the ability to prevent the precipitation of the glitter pigment is poor. Furthermore, the friction resistance of the coating film was not satisfactory.

  In order to prevent the precipitation of glittering pigments, efforts have been made to prepare emulsifier type eye liners instead of water based agents, or to increase the viscosity of water based eye liners with water-soluble polymers to make them highly viscous. ing. However, if the system is emulsified, the liquid appearance will become cloudy and vivid color will not be obtained, and the film pressure of the coating will increase, resulting in poor friction resistance. There was a problem that. On the other hand, when the viscosity is simply increased, the elongation of the liquid is deteriorated and the writing quality is deteriorated, and the effect of preventing the precipitation of the glitter pigment is not obtained.

JP 2004-277362 A

  The object of the present invention relates to a water-based eyeliner composition that is excellent in abrasion resistance, has a vivid color and smooth writing, and has good storage stability.

As a result of intensive studies to achieve the above-mentioned object, the present inventor combined a glitter pigment, carbon black, a microorganism-derived polysaccharide, a volatile alcohol, and an alkyl acrylate copolymer emulsion in combination. The inventors have found that an aqueous eyeliner composition having excellent friction resistance, vivid color development and good writing feel, and having good storage stability can be obtained, and the present invention has been completed.

That is, the present invention provides the following components (A) to (E):
(A): Bright pigment (B): Carbon black (C): Microorganism-derived polysaccharide (D): Volatile alcohol
(E): An aqueous eyeliner composition comprising an alkyl acrylate copolymer emulsion.

  INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a water-based eyeliner composition which is excellent in friction resistance, has a vivid color development and good writing, and has good storage stability, which is not in the prior art.

  Hereinafter, embodiments of the present invention will be described in detail.

  In this specification, an aqueous system is a non-emulsifying type, uses water as a main solvent, and further contains 30% by mass (hereinafter referred to as%) or more of water based on the total amount of the cosmetic. Refers to that.

  The glitter pigment of component (A) used in the present invention is not particularly limited as long as it is generally used in cosmetics, and any pigment can be used. For example, mica titanium, pigment coated mica titanium, metal coated glass powder, titanium oxide coated glass powder, titanium oxide coated synthetic phlogopite, iron oxide / titanium oxide coated synthetic phlogopite, fish scale foil, bismuth oxychloride, aluminum powder, iron oxide Coated aluminum powder, polyethylene terephthalate / aluminum / epoxy laminated powder, polyethylene terephthalate / silver / epoxy laminated powder, polyethylene terephthalate / polyolefin laminated film powder, polyethylene terephthalate / polymethyl methacrylate laminated film powder, etc. are used.

  Among these, it is preferable to use dye-coated mica titanium because it can exhibit more vivid and excellent color development. The dye used here may be either an organic dye or an inorganic dye. Examples of the dye-coated mica titanium include iron oxide-coated mica titanium, carmine-coated mica titanium, carmine / conjucite-coated mica titanium, iron oxide / carmine Examples include titanium coated mica, titanium mica coated titanium, iron oxide / konjiki coated mica titanium, chromium oxide coated titanium mica, titanium black coated titanium mica, and the like.

  In the present invention, one or more of these can be selected and used from time to time, and the blending amount is preferably 0.01 to 40%, more preferably based on the total amount of the cosmetic. Is 10-30%. If it is in this range, it has a vivid color and can further improve the good storage stability.

The carbon black of the component (B) used in the present invention is not particularly limited as long as it is generally used in cosmetics, but in order to produce a more vivid color, it was dispersed using water as a solvent. It is desirable to use an aqueous dispersion. Furthermore, if the dispersion diameter of 90% or more of the pigment particles is controlled to 0.7 μm or less, it is more preferable in terms of storage stability such as pigment aggregation and sedimentation. In detail, those described in JP-A-2002-363031 and the like can be used. In addition, also about the definition of said aqueous dispersion and a dispersion diameter, it follows the definition described in this Unexamined-Japanese-Patent No. 2002-363031. Examples of such commercially available products include TNP series (manufactured by Mikuni Dye Co., Ltd.).

  In the present invention, the blending amount is preferably 0.01 to 10%, and more preferably 0.1 to 5.0%, based on the total amount of the cosmetic, with respect to the pure carbon black. If it is in this range, it has vivid color development and good storage stability can be further enhanced.

  The microorganism-derived polysaccharide of the component (C) used in the present invention is a polysaccharide produced by a microorganism, optionally purified and heat sterilized, and is generally used in cosmetics. Can be used without particular limitation. For example, xanthan gum, gellan gum, dextran, succinoglucan, bull run and the like can be exemplified. Of these, the use of xanthan gum is more preferable in terms of smooth writing and storage stability without aggregation and precipitation of pigments.

  In the present invention, one or more of these can be selected and used as appropriate, and the blending amount is preferably 0.01 to 5.0% with respect to the total amount of the cosmetic, Preferably it is 0.05 to 3.0%. Within this range, excellent storage stability can be further enhanced while having a smooth writing taste.

  The volatile alcohol of component (D) used in the present invention is not particularly limited as long as it is generally used in cosmetics, and any one can be used. Further, in this specification, “volatile” means a tendency that 97% or more evaporates within 1 hour when it comes into contact with the skin. That is, this component (D) is an alcohol having a vapor pressure of preferably 0.7 kPa to 40 kPa in a liquid state under conditions of a temperature corresponding to the skin (30 ° C.) and atmospheric pressure (1 atm). Examples include ethanol, isopropanol, phenoxyethanol, phenoxyisopropanol, and the like. These are usually used as cosmetics, solvents, and antibacterial agents in cosmetics, but in the present invention, only when the components (A) to (E) are combined and blended, The present inventors have found that a water-based eyeliner that can completely prevent precipitation and aggregation of a pigment such as carbon black and that has a smooth writing taste is obtained, which is completely different from the conventional purpose of use.

  In the present invention, one or more of these can be selected and used as appropriate, but phenoxyethanol is most preferred. The blending amount is preferably 0.01 to 15%, more preferably 0.1 to 10% based on the total amount of the cosmetic. Within these ranges, good storage stability is particularly good.

  The alkyl acrylate copolymer emulsion of component (E) used in the present invention is not particularly limited as long as it is generally used in cosmetics, but exhibits more vivid color development and high friction resistance. Therefore, it is desirable to use methacrylic acid as the acid monomer. Furthermore, it is more preferable if the light transmittance before the coating film formation of the 0.6 wt% aqueous resin component is 60% or more when measured with a spectrophotometer at a wavelength of 425 nm. In detail, those described in JP-A-2005-2207 and the like can be used. In addition, what is described in this Unexamined-Japanese-Patent No. 2005-2207 can be used also about the measuring method of the said light transmittance, and the composition of another monomer. Examples of such commercially available products include iodosol GH256 (manufactured by NSC Japan).

  In the present invention, one or more of these can be selected and used as appropriate. The blending amount is preferably 0.1 to 40%, more preferably 0.5 to 30% with respect to the total amount of the cosmetic. Within these ranges, vivid color development and high friction resistance can be obtained. If it exceeds 40%, the fluidity is lost and the writing quality may deteriorate. On the other hand, if it is less than 0.1%, desired color developability and friction resistance may not be obtained.
