Description

Compositions of a Mascara

The present invention relates to a mascara composition, in particular, by using a natural sugar ester and spherical natural cellulose to give the function to make the eyelashes rich and long, and to minimize the change of the contents over time and eye irritation, as well as stability, color development, persistence, etc. It relates to a mascara composition improved.

In general, mascara is applied to the eyebrows to make the eyebrows dark and long, as well as to enhance the expressiveness and beauty of the eyes, and can be classified according to the formulation and function.

First, when the mascara is classified according to the formulation, it can be classified into an emulsion type emulsified, a dispersion type in which a film former and a powder are dispersed in a solvent, and a cake type molded by containing a film former in a powder. Among them, emulsion type is generally developed and marketed in terms of function (quality), stability, skin safety, and ease of use.

The mascara is slightly different in composition according to the formulation and function, but in the case of the emulsified mascara, water-soluble polymer and oil-soluble polymer are mixed to impart curling and thickness, a coloring pigment for imparting color and a dispersant for dispersing it, It is composed of a plasticizer for softening the film-forming agent, an emulsifier for emulsification, and the like.

Looking at the raw material composition of the emulsified mascara composition, as the film forming agent, acrylic derivatives such as acrylic and modified acrylic, polyethylene, carboxyl and derivatives thereof, chitosan and its derivatives, polyvinyl and derivatives thereof, and the like, triethanol Amine, its neutralizing substance, maleic acid copolymer, etc. are widely used, and as an emulsifier, polysorbate, sorbitan and its derivatives, polyglyceryl glucostearate, etc. are used. In addition, powders include ion oxide, ultramarine, cellulose, silica, sericite, kaolin, etc., and waxes include high melting point waxes such as carnauba lead, candelilla lead, ceresin, and microcrystalline. Rosinates are also used for adhesion.

The emulsified mascara composed as described above takes an emulsified form in the formulation, but contains a large amount of water and oil-soluble film-forming agents for the purpose of functioning, and thus the point and hardness continue to increase with time after manufacture, thereby causing the contents to harden. As a result, not only agglomeration occurs but also a problem of deterioration in functions such as curling, volume, and adhesion.

On the other hand, depending on the functional aspects, mascara is a volume type that enriches thin eyebrows, a curling type that raises sagging eyebrows, a long lash type that lengthens short eyebrows, a treatment type that gives glossiness to eyebrows, and strong water resistance. There are many types such as water-proof type, but the most common type is volume and curling type, and there are mixed type with long lash or treatment function.

In order to impart this function, water and oil-soluble film-forming agents act as important factors in the case of curling type, and powder acts as an important factor in the case of volume type. In the case of long lash, water, oil-soluble film forming agent and powder are also important factors at the same time.

The mascara of the volume type is to enrich the eyelashes. The volume type mascara is divided into mascara prescribed by using a water-soluble polymer as a main material, or mascara prescribed by using a sieving pigment, such as silica, talc, kaolin, cellulose powder, or a mascara appropriately mixed with it.

However, in the case of the volume mascara having the water-soluble polymer as the main material, the adhesion and the durability are excellent, but there is a problem in that stickiness occurs and the volume feeling is somewhat reduced.

In addition, the mascara mainly made of powders such as kaolin, talc, silica, etc. have no affinity with eyebrows, and thus powder powder falls off over time, making eyebrows dirty. In particular, mineral powders such as kaolin, talc, etc. The used composition is heavy in usability, the color itself is not vivid due to the presence of impurities in the powder itself, there is a problem inferior in safety.

In addition, the volume-type mascara using the synthetic powder such as silica is relatively lighter than the composition using the mineral powder, which does not burden the eyes, but there is a lot of powder fall off and there is a serious change over time.

Therefore, in order to solve the above problems, mascara using natural cellulose has been studied in recent years. For example, there is a mascara composition for making eyebrows long using plate-shaped cellulose extracted from ramie, and other researches on mascara using natural vegetable materials have been conducted.

However, the mascara composition using the natural cellulose is light, excellent in safety, and has an affinity with eyebrows, so that there is less powder falling, while it is difficult to develop a material having excellent function as well as a hydroxyl group in the cellulose (-OH group). There is a problem with the change over time.

Therefore, in order to reduce the change over time by using glycols such as 1,3-butylene glycol, but somewhat improved, there is a problem that the usability is not satisfactory and heavy.

An object of the present invention is to solve the above problems, and in particular, relates to a mascara composition that is excellent in safety and minimizes the change over time while making the eyelashes rich and long.

In order to achieve the above object, the mascara composition of the present invention forms a spherical vegetable cellulose and an inter, intra hydrogen bonding by using a plant-derived sugar ester which is a natural plant material having excellent safety as a thickener. It is characterized by.

Hereinafter, the present invention will be described in detail.

The present invention is to use a vegetable-derived sugar ester excellent in skin safety and spherical cellulose to enhance the volume function to make the eyelashes rich and long look as a main material, which will be described in detail as follows.

The vegetable-derived sugar ester has 8 hydroxy groups and 1 carboxyester group in 1 molecule, and the carboxyester group has 50-70 mono ester, 30-50 di or tri ester. The hydrophile-lypophile balance (HLB) is 8-18.

In addition, the vegetable-derived sugar ester is 0.1-20.0% by weight based on 100% by weight of the sucrose stearate, sucrose acetate stearate, sucrose tristearate, sucrose ricinolate, etc. It is preferably used at 0.5-5 weight. At this time, if the vegetable-derived sugar ester is 0.5 weight or less with respect to 100 weight of the emulsified composition, it cannot effectively control the point and hardness, and the dispersion stability effect is inferior, whereas if it is 10.0 weight or more, the point and hardness can be stably controlled and the dispersion stability This is excellent, but it causes stickiness and bunching.

In addition, the spherical vegetable cellulose is a cellulose obtained by hydrolysis and a special process of cellulose acetate in the neck, the average particle size of 8-10㎛, the globular spherical shape, the composition ratio of ethyl and methyl 3: 7-7: 3, the total surface area is 9.0-10.0 m / g, and the specific gravity is 0.6 ± 0.1.

The cellulose powder is 0.1-20.0% by weight of the emulsion composition, preferably 3 to 10% by weight, when the blending ratio is less than 3%, the function of enriching the eyelashes is reduced, whereas when it is 10 or more changes by gelling ability Becomes relatively severe, and powder dropping occurs over time after use.

The present invention configured as described above has a difference in stability and the like depending on the pH, when the pH is 5.5-7.5 is the most stable. If the pH is less than or equal to 4.5 or more than 7.5, dissociation of the materials occurs over time, stability decreases in the contents, and aggregation occurs.

The following is described in more detail with reference to the following embodiments of the present invention configured as described above. However, these examples are intended to illustrate the present invention, it is obvious to those skilled in the art that the scope of the present invention is not limited to these examples. Compounding amount is shown by weight.

Examples and Comparative Examples:

Referring to Table 1 shown below in detail the manufacturing process as follows. First, the raw materials 1-8 containing purified water, a dispersing agent, a film forming agent, and a sugar ester are weighed out, and then heated to dissolve. At this time, the dispersing agent is an isobutyrene sodium maleate copolymer, it is possible to solve the problem that can not effectively control the point, the hardness by chemical reaction with some of the film-forming agent over time when using the triethanol generally used.

Further, in the heat-dissolved solution, the raw material 9-12 containing the mineral, synthetic powder kaolin, silica, and natural vegetable powder, which is a vegetable cellulose of the present invention, is added and stirred by a homomixer. At this time, the vegetable cellulose is obtained through hydrolysis and special processes as follows.

First, the cellulose acetate is dispersed and solvent evaporated, and then neutralized by washing with water and saponification. The neutralized cellulose acetate is thus washed with water, sorted according to the particle size, and dried to obtain the above-mentioned vegetable cellulose.

Raw materials 13-21 containing emulsifiers and waxes are weighed into a solution which is stirred and dispersed as described above, heated and dissolved, and then emulsified with a homomixer. Furthermore, after adding the raw material 22 to emulsify it, it cools and stores at 30 degreeC. In this case, the waxes have a carboxyl group in beeswax, which is not only excellent in affinity with the eyebrows and dispersibility, but also can reduce the content of the high melting point waxes by the gelling effect, thereby making the usability smooth.
