Description

Eye Make-up Cosmetic Composition Comprising Waxes with Glyceryl group and flexible film formers}

The present invention relates to an eye makeup composition containing a wax containing a glyceryl group and a flexible film polymer, and more particularly, a polysilyl group is added to a wax and a styrene group to give a soft and nutritious spreading effect by adding a glycyl group, thereby providing a flexible and excellent fixing force. By containing an acrylate-based polymer in an optimal ratio, the present invention relates to an eye makeup composition that solves the bleeding problem accompanied by the soft and light spreadability and volume improvement of mascara.

In general, mascara's functions are divided into volume, curling, long lash, and waterproof, and because Asian women's eyelashes are shorter and thinner than those of Western women due to the characteristics of eyelashes, Asian women are more concerned about volume The tendency to favor features is evident. Volume mascara in mascara means that the thinning of the eyelashes appears more than the original state, many methods have been developed in the past to give this volume.

Eye makeup compositions containing wax, film polymers, and spherical powders, especially mascaras, make the eyelashes look beautiful and healthy by making them look sharp and thin, typically with waxes, water soluble thickeners, oils, pigments, and film polymers. , Fillers, antioxidants, preservatives, fragrances and other nutritional ingredients.

Conventionally, the technique of increasing the volume of the eyelashes has been developed in the direction of increasing the amount of adhesion to the eyelashes by using a large amount of solids, that is, wax, adhesive powder, etc., and the volume power is increased in consideration of the complexities of use according to the type of solids While mascara has been developed with improved usability.

Another thing to consider when using mascara is smearing. Asian women with eyelashes facing down are more likely to smear mascara applied to their eyelashes under the eyes, so bleeding is one of the mascara's important attributes for Asian women. Due to the characteristics of the volume mascara that is applied in a large amount, there is a limit to satisfy both the excellent volume power, the soft usability, and the property that does not spread.

Many cosmetic compositions, including volume mascara, typically use a large amount of wax to improve the stability and volume of the formulation.However, when a large amount of wax is used, the crystallization phenomenon of the wax generally causes a change in the cosmetic composition over time. In some cases, dryness and agglomeration are present, and a large amount of content is deposited on the eyelashes, resulting in bleeding under the eyes.

In addition, many cosmetic compositions, including volume mascara for oriental women, generally include a film polymer for the purpose of preventing smear after applying the cosmetic to the eyelashes. There was a disadvantage in that it felt dry or felt foreign matter after the film was formed.

Thus, the present inventors have studied the eye makeup composition that does not bleed while having excellent volume and soft feeling, as a result of the addition of wax and styrene groups on the paste with the addition of glyceryl group, while maintaining a soft feeling by using a flexible film polymer in an optimum ratio The bungee found that it could solve the problem and completed the present invention.

Accordingly, it is an object of the present invention to provide an eye makeup composition which is excellent in feeling and volume and free of smearing.

In order to achieve the above object, the present invention provides an eye makeup composition containing, as an active ingredient, a film polymer to which a wax containing a glyceryl group and a styrene group are added.

The eye makeup composition according to the present invention provides a soft application and differentiated from the existing eye makeup composition and shows an excellent volume, especially since there is no bleeding over time, people with less eyebrows, people with no power on the eyebrows, volume Those who prefer older mascara, and those who prefer mascara that are light and soft, will be able to meet the needs of various people.

1 is a photograph showing the spreading effect of the composition according to the present invention.

The present invention provides an eye makeup composition containing a wax containing a glyceryl group and a film polymer to which a styrene group is added as an active ingredient.

Hereinafter, the present invention will be described more specifically.

As used herein, the term "wax" refers to a component that retains the hardness of the lipid component with a higher monovalent or dihydric alcohol fatty acid ester that is insoluble in water. The wax of the present invention is any physiologically acceptable, specifically cosmetically acceptable material, and may in particular be of mineral, animal, plant or synthetic origin.

Wax including a glyceryl group used as an active ingredient in the present invention can give a softer feeling by the water-containing properties of the glyceryl group. Waxes containing a glyceryl group that can be used in the present invention include bis-diglyceryl polyacyl adipate, acetyl glyceryl ricinoleate, glyceryl ranolate and the like, but using a bis-diglyceryl polyacyl adipate system Most preferred. Examples of commercially available ones include Kahlwax 6421 from Kahl Gmbh & Co., Softisan 649 from Sasol Germany GmbH, AEC Glyceryl Lanolate from A & E Connock Ltd., and Ivarlan 3360 from Arch Personal Care Products.

Bis-diglyceryl polyacyl adipate-2 used in the present invention not only moisturizes the glyceryl group, but also has a low melting point of 10 to 40 ° C., which is present as a soft paste even at room temperature. It is most desirable to use because it maintains a smooth feeling without using.

As used herein, a "film polymer" refers to a compound formed by polymerization of molecules to form a thin film on the surface to maintain curling of eyelashes and to prevent pigments in the inner layer from getting under the eyes. In addition to mascara, these polymers are used in hair fixing products such as hair gels, mousses, waxes, sprays, etc. Among them, short eyelashes are fastened and eye irritation and non-sticky polymers are used.

Examples of the film polymer to which the styrene group used as the active ingredient in the present invention are added include styrene methacrylate, amino methylpropanol-acrylate, and polyacrylate. Specific examples thereof include styrene / ammonium / meta. Acrylates, polyurethane-14, amino methylpropanol-acrylate copolymers, amino methylpropanol-acrylate / aryl methacrylate copolymers, polyacrylate 2-cross polymers, polyacrylate-14, and the like. Most preferably, styrene / ammonium / methacrylate is 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.

The film polymer to which the wax and styrene group containing the glyceryl group of this invention were added is contained in 0.1 to 25 weight%, More preferably, 7 to 15 weight% with respect to the total weight of a composition. It is preferable because less than 0.1% by weight of the film polymer is included in the formulation, even if it contains less than 25% by weight, the formulation is hardened, the powder is hardened, the powder falls and the hardness of the formulation rises, the contents dry quickly and the feeling is not smooth Not.

The optimum ratio of the film polymer to which the wax and styrene group which added the glyceryl group of this invention was added is a weight ratio of 1: 3-3: 1. In detail, the weight of the wax containing the glyceryl group is 25 to 75% of the total weight of the film polymer added with the glyceryl group and the styrene group, and the weight of the film polymer added with the styrene group is 75 to 25%. it means. When the content of the wax containing glyceryl group is less than 25% of the total weight of the film polymer added with the wax and styrene group including the total glyceryl group, there is no bleeding phenomenon but no soft feeling, whereas the wax and styrene group including the whole glyceryl group If it exceeds 75% of the total weight of the added film polymer, the feeling of applying smoothly is excellent but the bleeding may be severe. In addition, when the weight of the film polymer to which the styrene group is added is less than 25% at the same content, the feeling becomes better, but the bleeding phenomenon appears, and when it exceeds 75%, there is no bleeding phenomenon, but the soft feeling does not appear.

The mascara composition of the present invention may further contain a non-porous spherical powder in addition to the mixed use by the optimum ratio of the wax and the styrene group added film polymer including a glyceryl group to provide a smooth feeling and bleed-free effect at the same time.

Since the non-porous spherical powder used in the present invention is spherical in shape, it is a powder that is smoothly applied as if rolling on the eyelashes, but spherical powders include nylon and silica, but silica is porous and the surrounding powder is changed over time. It is not preferable because it adsorbs and changes over time. Therefore, mascara uses a small amount of silica to minimize the change over time and improve the feeling of use, which is not high enough to affect the feeling, and thus, in the present invention, it contains a non-porous nylon powder to double the soft feeling and to change the change over time. Minimize.

The mascara composition of the present invention contains the aforementioned non-porous spherical powder in an amount of 1.0 to 5.0% by weight based on the total weight of the composition. This is because when used in less than 1.0% by weight is too small to expect the effect of improving the feeling, when used in excess of 5.0% by weight has a disadvantage in that agglomeration phenomenon due to the properties of the powder itself.

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. It is intended to facilitate the implementation of the invention to those with knowledge.
