Description

Low Viscosity Mascara Composition

This application claims the benefit of priority based on Korean Patent Application No. 10-2015-0137868 filed on September 30, 2015, and all content disclosed in the literature of that Korean patent application is incorporated as part of this specification.

The present invention relates to low viscosity mascara compositions capable of forming a uniform volume without agglomeration.

Mascara, which is one of the makeup products used to express the eyelashes richly and beautifully, is generally applied 4 to 20 times when used.

While mascara formulations with various functions such as volume, length, and spreadability have been improved on the market, there are not enough mascara formulations that are applied without aggregation to give a uniform density like natural eyelashes even when applied several times. .

In particular, the recent makeup trend is that the mascara brush with a shorter brush and a lighter form is preferred in consideration of the ease of carrying and the convenience of use. Since the aspect of the physical force acting on is different, when applying the conventional mascara composition with a short brush mascara brush, it shows a more unsatisfactory feeling.

For example, the applicability is lowered due to excessively stiff feeling, and when applied several times, the eyelashes and the composition of the multiple strands are united together due to the uneven application of the composition, resulting in a poor appearance.

In some cases, as an attempt to solve this problem, a mascara composition containing a higher fatty acid alcohol as an oil-soluble wax and further containing an alumina powder, which is a plate powder, has been proposed. And while it may have an effect such as under-eye bleeding there was a problem that can not form a uniform volume without agglomeration.

Accordingly, various studies have been conducted to provide a more improved form of mascara composition, and in the process, it is possible to provide a mascara composition of a lower viscosity formulation beyond the viscosity (120,000 to 250,000 cps) range of a conventional general mascara formulation. I realized the need.

However, when the viscosity of the mascara composition is lowered, there is a problem that the wax crystallization property for curling is lowered and the adhesion of the eyelash composition imparted by the wax is reduced, so that there is a technical limitation for implementing the low viscosity mascara composition.

As used herein, the term "appliability" refers to the efficiency of applying the composition to the site as the mascara brush touches, and has excellent softness when the composition is excellent in applicability.

In addition, the term "cohesion" means that the application of the composition is applied evenly and evenly without clumping the eyelashes and the composition. Without agglomeration, it is possible to have an excellent application even when the first application as well as to apply several times and to form a uniform volume throughout the eyelashes.

On the other hand, the term "adhesive" in the present specification means a degree that is firmly attached to the eyelashes without blowing or dripping powder after application.

The subject of the present invention is applied to the eyebrow or eyelashes as the 'mascara composition' in the present application, but considering the purposes and effects of the present invention, the human hair tissue, such as hair (including keratin) hair) and the like.

Hereinafter, the present invention will be described in more detail. However, the following contents are described only for the most representative embodiments in order to help the understanding of the present invention, and the scope of the present invention is not limited thereto, and the present invention should be understood to cover all ranges equivalent to the following contents.

Low Melting Butter and Wax Compositions

Mascara compositions of the present invention comprise butter and wax compositions as one component. The wax composition is composed of a low melting point butter and a low melting point wax, characterized in that the total content of the wax composition is reduced compared to the conventional. Due to this, the mascara composition of the present invention can realize a low viscosity composition so that it can be smoothly applied without being stiff, and a uniform layer is not formed between the compositions or clumps between the eyelashes and the composition.

Specifically, the low melting butter is preferably used at least one selected from the group consisting of shea butter, cupu butter butter, babasu butter, cacao butter. More preferably, shea butter may be used, which may allow the mascara composition to easily slide on the eyelashes.

The low melting butter is contained 1 to 10% by weight based on the total weight of the mascara composition. If it is included in the range below the mascara composition is not sliding well on the eyelashes to cause a lack of applicability or agglomeration of the composition, if included in the above range because the formulation is too slippery can be formed.

As the low melting point wax, it is preferable to use one or more selected from the group consisting of bees wax, paraffin wax and candelilla wax. More preferably, it may comprise a bead wax and a paraffin wax, which is included as a central component of the wax composition to play an important role in increasing the adhesion of the mascara composition to the eyelash keratin and aids in wax crystallization and curling power. To increase. Meanwhile, paraffin wax improves curling functionality and enhances water resistance through wax crystallization along with application of mascara.

When the low melting wax includes the bead wax and the paraffin wax, the wax wax may contain 2 to 10 wt% of the wax wax and 1 to 10 wt% of the paraffin wax, based on the total weight of the mascara composition. If included in the range below the function and role of each wax is lowered, if included in the above range is because the crystallization phenomenon of the wax is excessive and may cause inconvenience to use.

However, the total content of the low melting wax is 10 to 30% by weight based on the total weight of the mascara composition. If it is included in the range below the total content of the wax is too small to form the formulation of the composition is not properly formed or to compensate for the relatively high content of the high melting point wax as conventional, if included in the above range This is because the total content of the wax may increase, making it difficult to control the viscosity and reduce the volume.

In addition to the low melting butters and waxes described above, the wax compositions of the present invention include some high melting point waxes, and the types of the high melting point waxes include, for example, microcrystalline crystals, carnauba waxes, carnauba waxes, and synthetic waxes. One or more selected may be used, but is not necessarily limited thereto.

The content of the high melting point wax is 0.2 to 10% by weight based on the total weight of the mascara composition. In the case where the high melting point wax is included below the above range, most of the wax composition may include only the low melting point wax to reduce the volume or curling force, and when included in the above range, it is difficult to control the viscosity so that aggregation occurs. Because it can.

Polymer plasticizer

The mascara composition of the present invention includes a polymeric plasticizer as another component. The polymer plasticizer is involved in the crystallization of the wax and enhances the adhesion of the composition and imparts persistence, it is possible to form a relatively rich volume even with a small number of application.

As the polymer plasticizer of the present invention, polybutene-like plasticizers may be preferably used. The polybutene-like plasticizers include hydrogenated polyisobutene or polybutene, and the like materials may be further subdivided according to molecular weight. For example, hydrogenate polyisobutene of molecular weight (Mw) 370, 13300, polybutene of molecular weight (Mw) 900, 1400, 2000, and the like.

In the mascara composition of the present invention, hydrogenated polyisobutene (molecular weight 1300) may be used most preferably, but not necessarily limited thereto, in order to realize excellent sustainability and agglomeration without agglomeration.

The polymer plasticizer is contained in 1 to 10% by weight based on the total mascara composition. If the polymeric plasticizer is contained in the above-described content range, the flexibility of the wax is increased, and the mascara composition can be adhered well on the eyelash keratin, so that the composition can form a uniform volume without agglomeration at the first application and application. .

Aminomethylpropanediol-fatty acid ester

Meanwhile, the mascara composition of the present invention uses fatty acid esters obtained by reacting aminomethylpropanediol with fatty acids instead of using nonionic surfactants and other emulsifiers. Accordingly, the aminomethylpropanediol-fatty acid ester compound is included in the composition to provide dispersing power and to stabilize the system.

Specifically, the fatty acid constituting the aminomethylpropanediol-fatty acid ester compound may be a substance having 12 to 22 carbon atoms, such as lauric acid, palmitic acid, myristic acid, stearic acid, behenic acid, or the like. It can be used in combination, preferably lauric acid (C12) may be used alone or at the same time it can be used in combination of palmitic acid (palmitic acid, C16) and myristic acid (myrisitic acid, C14).

In particular, fatty acid esters (soap) having the preferred fatty acid composition is a novel combination material of the form newly proposed for the composition of the present invention as a different material from the fatty acid ester used in the conventional makeup composition. In the past, stearic acid and palmitic acid-based fatty acid esters were mainly used, in which case there was a problem such as causing aggregation and deterioration of the coatability when prescribing a high content of the film-forming agent. Alternatively, when a fatty acid combination of palmitic acid and myristic acid is used, application property and agglomeration property may be improved, thereby improving physical properties of the composition.

However, lauric acid has a high self-solubility and a lot of bubbles, and if the content is high, the stability is not good, and especially when mixed with more than 7% by weight, irritation may occur, so that it is not included in the above content.

The aminomethylpropanediol-fatty acid ester compound is obtained by reacting aminomethylpropanediol in an equivalent ratio of 1: 0.7 to 1: 0.98 to fatty acids. When the reaction equivalence ratio of aminomethylpropanediol to fatty acid is less than 0.7, the neutralization ratio between aminomethylpropanediol and fatty acid is less than 30%, making it difficult to function as an emulsifier and phase separation occurs when testing the stability of the composition. This is because the neutralization ratio between aminomethylpropanediol and fatty acids is more than 98%, so that the composition is excellent in stability, but the hardness is too high, resulting in poor applicability and difficulty in uniform application.

The aminomethylpropanediol-fatty acid ester is to be contained in 1 to 15% by weight based on the total weight of the mascara composition. This is because if the content is less than the above range, the system is not stabilized and the phases are separated. If the content exceeds the above range, the composition is stiff and the applicability is reduced. More preferably 3 to 9% by weight of the above content range.

The aminomethylpropanediol-fatty acid ester may be used in the form of a mixture containing unreacted fatty acids, wherein the unreacted fatty acid in the mixture is preferably contained in 2 to 80% of the total weight of the fatty acids added to the reaction.

The low-viscosity mascara composition of the present invention described above may be applied through any type of brush, but more preferably, the brush may be applied with a short mascara brush. The length of the brush brush affects the characteristics of the physical force transmitted to the application site during use, and thus, the optimum properties of the mascara composition used are different. In the case of using a brush having a short brush, a low viscosity as in the present invention It is because the composition of can be apply | coated most effectively.

Hereinafter, examples, comparative examples and test examples are presented to help understand the effects of the present invention. However, the following test examples only correspond to one test example regarding the configuration and effects of the present invention, and the scope and effects of the present invention are not limited thereto.
