Description

High adhesion eye makeup composition

This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0111763 dated August 31, 2016, and all the contents disclosed in the literature of that Korean patent application are incorporated as part of this specification.

The present invention relates to a high-adhesion eye makeup composition, and more particularly to an eye makeup composition containing a plate-like powder and spherical powder to enhance adhesion and excellent applicability.

In general, the function of mascara is to apply the eyelashes to curl the eyelashes long, to give a sense of volume to emphasize the eyes and to give an expression to the eyes. In mascara, the sense of volume means that the mascara is applied to the eyelashes in abundance so that the eyelashes are thinner and richer than the original state. In particular, Asian women who have relatively poor eyelashes and small eyes compared to Western women have a greater desire to express deeper and longer eyebrows. Therefore, the expectation of the volume function of mascara is high.

Accordingly, many methods have been developed to improve the volume function, and in general, a large amount of polymer or a powder which forms a wax or a film in the oil phase has been used.

Particularly, powders are easily used in volume mascara because they can easily show a sense of volume as the content is increased. Recently, a spherical powder having a round shape such as nylon, silicone-based resin, polymethmethylacrylate, etc. is used. Specifically, Japanese Patent Application Laid-Open No. Hei 11-12132 discloses an eye makeup composition which contains a silicone resin powder such as polymethylsilsesukioki acid and is prepared by a phase inversion emulsifision, thereby having an excellent volume feeling. It is. However, the spherical powder provides excellent volume due to the round shape, but has a disadvantage of falling off the eyelashes when applied without applying evenly because the adhesion area with the eyelash surface is small.

In order to improve this disadvantage, eye makeup compositions prepared by blending hydrocarbon-based oils with spherical powders are disclosed in Japanese Patent Laid-Open No. 2004-315420. However, the eye makeup composition is excellent in volume and curling retention by using a spherical hollow powder, but the oil used to improve the applicability has a disadvantage of causing eye bleeding and difficult to apply over time.

On the other hand, when flat plate powders such as mica, talc, and sericite are used, they are applied in close contact with the surface of the eyelashes, but they apply very tightly, but the amount of volley is too small to reduce the volume. Increasing it may cause the texture to stick together or the mascara texture becomes pervasive.

Republic of Korea Patent Publication No. 0709612, "Mascara composition"

In order to solve the above problems, the most commonly used technique for making a formulation having excellent coating properties is to form a skeleton by a saponification reaction in which a fatty acid reacts with an amino base. This shows good applicability through shear-thining properties, which are easily broken by application, which results in a very poor persistence in water for the formulation thus formed. In order to improve this, the high-strength film-forming agent is used in a high content to increase the persistence. In this case, there is a problem in that the coated surface becomes rough or does not slide when padding is applied. Therefore, spherical powder or amorphous wax or low-viscosity wax is used in the prior art to increase sliding while bringing shear-thining and sustainability, which decreases adhesion and decreases volume and increases the number of overcoats. Again, the chart surface is roughened.

Therefore, an object of the present invention is to provide an eye makeup composition which improves the surface of the application and improves the clean volume by improving the adhesion while maintaining the existing smooth application and persistence.

In order to achieve the above object, the present invention provides a high adhesion eye makeup composition comprising a weight ratio of the plate-shaped powder and the spherical powder is 4: 1 to 2: 1.

The eye makeup composition according to the present invention has excellent adhesion and sliding, so that the surface of the coating is improved and exhibits a function of clean volume force without clumping to satisfy the ideal requirement of mascara.

1 is a test result image of Example 1 and Comparative Example 3 of the present invention.

The present invention includes a plate-shaped powder and a spherical powder, and includes a film-forming agent which is a combination of an alkyl acrylate copolymer and an acrylate group added with a styrene group in a high content, and softly spreads and sustains to form a formulation through a saponification reaction. Provides eye makeup compositions that improve adhesion and improve volume while maintaining the volume.

According to a preferred embodiment of the present invention, the eye makeup composition is a cosmetic composition for mascara, eyeliner, eye shadow or eyebrow, more preferably a cosmetic composition for mascara or eyeliner, and most preferably a cosmetic composition for mascara.

In order for the eye makeup composition having excellent volume sense desired in the present invention, the adhesion and adhesion of the powder in the composition should be excellent, and the adhesion and adhesion of the powder depend on the size and shape of the powder particles. The plate-like powder used in the present invention is usually small particles in proportion to the particle size applied to the cosmetic composition.

In the case of small particles of plate powder, the spreadability is low and gives a stiff feeling, but the adhesion is excellent. The addition of spherical powder with excellent spreading properties along with good adhesion plate powders enables the simultaneous application of soft application and adhesion, which is the main feature of the formulation. Therefore, in the present invention, the plate-like powder and the spherical powder are preferably included in a weight ratio of 4: 1 to 2: 1.

The plate-like powder usable in the present invention has an average particle size distribution of 0.1 to 2.0 μm, more preferably 0.5 to 1.8 μm, for example, Talc, Mica, Kaolin, Alumina. Etc., but it is preferable to use talc. The plate-like powder is very thin so that it is thinly applied to the eyelashes, so it is hardly used to improve the volume.However, because of its large attachment area, it is smooth and smooth. Due to the surface characteristics, it has the advantage of applying very smooth and smooth. Generally, Whittaker, Clark & Daniels' alumina series (Activated 4082, Calcined 612, Tabular 635, Trihydrate 617, etc.) and Advanced Powder Technology's Alusion are commercially available.

The spherical powders usable in the present invention are those having an average particle diameter of 0.5 to 10 μm, more preferably 2.0 to 5.0 μm, such as spherical silica, nylon, vegetable cellulose, acrylic acid, acrylic acid esters, methacrylic acid and methacrylic acid. Although ester, acrylonitrile, etc. are mentioned, it is preferable to use spherical silica. The spherical powder is widely used because of its morphological characteristics, which can be attached to the eyelashes as thick as the diameter of the powder to give an instant volume improvement effect. Generally, J.Rettenmaier & Sohne's Arbocel series (A300, BC1000, FT600-30, etc.), Presperse's Celluflow C-25, and Tosco's Ramie Cellulose Powder are available.

The total weight of the plate-like powder and the spherical powder is included in 1 to 10% by weight, more preferably 1 to 5% by weight based on 100% by weight of the total composition. This is too small when using less than 1% by weight can not expect the coating effect of the powder, when used in excess of 10% by weight of the aggregates between the powder occurs and the dispersion is not easy to emulsify This is because it is difficult to formulate.

In addition, the term "film former" as used herein refers to a compound formed by polymerization of molecules to form a thin film on the surface to maintain curling of the eyelashes and to help prevent pigments in the inner layer from getting under the eyes. In addition to mascara, these ingredients are used in hair fixing products such as hair gels, mousses, waxes, sprays, etc. Among them, short eyelashes are quickly fixed and polymers without eye irritation and stickiness are used.

The eye makeup composition according to the present invention also contains a combination of an alkyl acrylate copolymer and an acrylate-based styrene group added as a film former.

Since the alkyl acrylate copolymer has a faster drying speed than conventional film forming agents such as polyvinylpyrrolidone, the adhesion amount to the eyebrows can be increased without bleeding and powder falling off, and a thin and firm film film on the eyebrows is provided. It is formed so that the makeup state can be kept clean over time. The kind of alkyl acrylate used in the present invention is not particularly limited, but for example, C10-30 alkyl acrylate copolymer or acrylate / C10-30 alkyl acrylate copolymer.

Examples of the acrylate to which the styrene group is added include styrene methacrylate, amino methyl propanol-acrylate, and polyacrylate. Specific examples thereof include styrene / acrylate / ammonium methacrylate and styrene /. Ammonium / methacrylate, polyurethane-14, amino methylpropanol-acrylate copolymer, amino methylpropanol-acrylate / aryl methacrylate copolymer, polyacrylate 2-cross polymer, polyacrylate-14, etc. However, styrene / acrylate / ammonium methacrylate is most preferably used. Examples of commercially available ones include Interpolymer Syntran series (5009, 5760), National starch & Chemical's Dynam X, Noveon's fixate series, G-100 Polymer, Super hold Polymer, and Plus Polymer. These polymers are commercially available in a variety of viscosities and molecular weights, and commercially available polymers were also used.

In the present invention, the combination of the alkyl acrylate copolymer and the styrene / acrylate / ammonium methacrylate copolymer is preferably used so that the weight ratio is 10: 5 to 10:10, and according to the embodiment of the present invention It was used in the weight ratio of 8. Alkyl acrylate copolymers having excellent durability have a disadvantage of roughening the surface upon coating due to differences in the drying rate between the outside and the inside, but styrene / acrylate / ammonium methacrylate copolymers having a phenyl group have soft characteristics. Therefore, it serves to soften some of the dried surface film of the alkyl acrylate copolymer.

In addition, the content of the film former is contained in an amount of 5.0 to 45.0% by weight, preferably 15.0 to 30.0% by weight, based on the total weight of the composition. When the content of the film-forming agent is less than 5.0% by weight, the film-forming effect is insignificant and does not contribute to the improvement of persistence, and when the content of the film-forming agent exceeds 60% by weight, the drying speed of the mascara composition is too fast, resulting in poor applicability.

In addition to the above components, the eye makeup composition of the present invention can be easily added by those skilled in the art in addition to the essential components in the manufacture of eye makeup to suit the function and use, specifically emulsifiers, waxes, defoamers , Preservatives, thickeners and the like.

Eye makeup composition according to the present invention is not limited to the manufacturing method, but is most commonly used as a technique for making a formulation having excellent applicability, by a soap (soap) reaction that reacts fatty acids and amino bases It is preferable to form a skeleton. Specifically, a soap which is a fatty acid ester, ie, a fatty acid ester is neutralized with a neutralizing agent to stabilize the system, and a polyglyceryl fatty acid ester, which is a wax crystal inhibitor, is mixed and used in order to continually excellent initial applicability.

In the present invention, in order to stabilize the system, instead of an emulsifier, a soap neutralized with a fatty acid ester is used, and the fatty acid ester is a higher fatty acid ester having 12 to 22 carbon atoms, and preferably palmitic acid having 16 to 18 carbon atoms; Stearic acid. When carbon number is less than 12 or more than 22, hardness and usability are not excellent. When the carbon number length of the fatty acid ester is less than 12, the carbon length is short and does not play an excellent role in applicationability, and the fatty acid ester having a carbon number of 12 or more, preferably 16 or more, forms the lamellar structure more easily. Since the structure is easily broken by the deformation force (stress) (shear shinning effect), for example, when applying mascara liquid to the eyelashes, the applicability is excellent.

As used herein, the term "neutralizing agent" is a substance having a function of neutralizing fatty acids, and has an effect of remarkable volume, curling and curling retention and suppressing powder fall.

According to a preferred embodiment of the present invention, the neutralizing agent included in the present invention is aminomethylpropanol (AMPD), aminobutanol (Aminobutanol), tetrahydroxypropylethylenediamine, diisopropanolamine (diisopropanolamine), triisopropanol At least one neutralizing agent selected from the group consisting of amine (triisopropanolamine), monoethanolamine and triethanolamine, most preferably aminomethylpropanol (AMPD).

The content of the neutralizing agent preferably comprises 0.1 to 10 parts by weight based on the total weight of the composition. When the content of the neutralizing agent is less than the above range, the composition is not stable due to fatty acids that are not neutralized, and when it exceeds the above range, the pH of the mascara is increased, so that the stability is not good, and it may cause eye irritation.

The amount of the neutralized fatty acid ester is 1 to 40% by weight and most preferably 5 to 30% by weight based on the total weight of the composition. In the present invention, the fatty acid ester acts as a wax crystal inhibitor, and therefore, when contained in less than 1% by weight, wax crystals do not inhibit growth and wax crystals grow over time, thereby preventing the initial smoothness and feeling of use. In the case of more than 40% by weight, there is a disadvantage that the initial composition viscosity is too low to remain applied to the eyebrows.

In addition, the neutralization degree of the neutralized fatty acid ester is adjusted to 30 to 98%, more preferably 60 to 80%, wherein the pH is to be maintained below 9. If the neutralization degree of fatty acid ester is less than 30%, it does not act as an emulsifier and the composition is not stable, resulting in phase separation.On the other hand, if the neutralization degree of fatty acid ester is more than 98%, the stability is good but the viscosity is high, and the applicability decreases. This is because there is a disadvantage that does not apply evenly.

As the degree of neutralization of the fatty acid ester increases, the shear-thining effect increases, but the pH also rises at the same time. According to the exemplary embodiment of the present invention, neutralization of stearic acid having 18 carbon atoms was performed with aminomethylpropanol (AMPD) so that the degree of neutralization was about 70%, at which time the pH was less than 9.

The subject of application of the present invention is preferably a mascara composition as an 'eye makeup composition', and the eyebrow or eyelashes are applied to the subject, but in consideration of the object and effect of the present invention, the human hair including all keratin ( It can also be extended to hair tissue, such as hair.

Hereinafter, the present invention will be described in more detail by explaining preferred embodiments of the present invention. However, the present invention is not limited to the following examples, and various forms of embodiments can be implemented within the scope of the appended claims, and the following examples are only common in the art while making the disclosure of the present invention complete.
