Description

Eye Make-up Cosmetic Composition

The present invention relates to an eye makeup cosmetic composition containing a natural pigment.

In general, eye makeup products include mascara, eyeliner, eye shadow and eyebrow, and these products contain a large amount of pigments (colorants). The purpose of blending pigments is to conceal the spots and freckles around the eyes and give a beautiful color effect to create a healthy and attractive eyes.

Pigments (colorants) that can be used in cosmetics can be largely divided into organic synthetic pigments, natural pigments and inorganic pigments, in particular, the pigments that can be used around the eyes should be more restrictive, safety is guaranteed.

Existing eye makeup cosmetic compositions were mostly synthetic dyes and coloring pigments. In other words, in the past, there were many developments of products using synthetic colors rather than natural colors. This is because of the difficulty in extracting natural pigments and the limited use of materials and uses.

However, in recent years, interest in natural materials and natural pigments is increasing according to well-being and eco-friendly trends, and the claim of the danger of synthetic pigments is emerging. Therefore, replacement with safer natural pigments is required, and natural pigments are synthetic pigments. More safety, physiologically active efficacy, effect is excellent, and mass production research is being made, the product development using natural pigments in the food and clothing as well as cosmetics is actively progressing.

Representative natural pigments contained in the existing eye makeup cosmetic compositions, which are brown pigments derived from brown cacao pigments present in cacao as prabon-based pigments, cochinyl pigments extracted from anthraquinone-based spring bugs, and yellow β- extracted from carrots. Carotene, red-lacquered Laccaic acid pigments extracted from rock worms, red safflower pigments extracted from safflower petals, capxanthin pigments extracted from paprika, and yellow crocuses extracted from gardenia fruit Sour pigments and the like.

However, these natural pigments have a disadvantage in that they have insufficient coating power due to their low coating power. Therefore, a study of natural pigments that can solve these problems is necessary, and in particular, natural pigments that can hold volume power, an essential function of eye makeup (eg mascara). There is a growing need for research.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

Specifically, an object according to an embodiment of the present invention is to provide an eye makeup cosmetic composition having abundant volume by excellent coating power without causing irritation.

Eye makeup cosmetic composition according to the present invention for achieving this object is composed of containing cellulose powder (powder) or green tea powder.

Since the eye makeup cosmetic composition containing the cellulose powder or the green tea powder contains natural pigments, it does not cause eye irritation, and has been noted as a disadvantage of the eye makeup cosmetic composition containing natural pigments. Can be improved.

As in the present invention, by using a green tea powder or cellulose powder of natural origin as a pigment, a composition exhibiting excellent volume power can be referred to as a novel eye makeup cosmetic composition that has not been reported so far.

The volume force (or volume effect) is a general term of the effect that can be produced to give a rich feeling to the eyebrows when the cosmetic composition is applied to the eyebrows in the eye makeup, the quality of the eye makeup cosmetic composition It can be an important criterion to evaluate.

In the conventional eye makeup, dyes, which are organic synthetic dyes, extender pigments, which are organic pigments or inorganic pigments, and pigmented pigments, are used as pigments, and in the case of using such dyes, cellulose powder, Silicone powder, alumina and the like have been used. However, when the cellulose powder or green tea powder according to the present invention is used in the eye makeup cosmetic composition, the cellulose powder, the silicone powder, and the alumina may be simultaneously provided with the colorant and the volume effect.

In addition, the eye makeup cosmetic composition according to the present invention may exhibit a natural color development power compared to the synthetic pigment, and because the particle size of the green tea powder or cellulose powder is about 1.5 to 2 times larger than that of the synthetic pigment, the volume may be excellent. .

In general, natural pigments may be discolored or discolored due to heat and light instability or discoloration, depending on the properties of raw materials, compared to general synthetic pigments. However, the cellulose powder or green tea powder has a large number of hydroxy groups (-OH) It is a stable compound that forms complex by forming coordination compound and displays color. It is very stable to heat and light. Accordingly, benzophenone derivatives, paraaminobenzoic acid derivatives, methoclockpinic acid derivatives or salicylic acid derivatives, butyl methoxydibenzoylmethane (Butyl Methoxydibenzoylmethane, Parsol # 1789) and benzo, which are commonly used ultraviolet absorbers to improve light resistance when using natural pigments There is an advantage that it is not necessary to use ultraviolet absorbents associated with benzophenone-5 derivatives.

The cellulose powder may include any type of cellulose powder dyed to exhibit a desired color suitable for eye makeup, but in one preferred embodiment, the cellulose powder is adsorbed to the microcrystalline cellulose through the mordant (cellulose- It may be laked).

In addition, the green tea powder may also include green tea powder in the form of any compound dyed to exhibit a desired color suitable for eye makeup, but in one preferred embodiment, the green tea powder is a reaction of tannin acid with a metal component of a mordant. It can form by forming a stable complex compound.

The color suitable for the eye makeup is not particularly limited as long as it is a color that can give a beautiful color effect around the eyes, but the color obtainable through the green tea powder or the cellulose powder which is colored by the dyeing agent with the mordant may be, for example, black, brown, Light brown or the like, and preferably black.

Most of the fine powder green tea is cellulose, and since tannin acid can be extracted from the fine powder green tea, the fine powder green tea can simultaneously achieve the functions of cellulose and salt material.

The green tea powder may be colored in a color suitable for eye makeup by reacting tannic acid in the extract extracted from green tea with a metal component of a mordant to form a complex compound.

The cellulose may be a conventional cellulose that is listed and used in cosmetic raw materials, Cellulobeads of Daito Kasei, Covadisperse of LCW and Lumiyan of Daiya Koq ( lllumi yarn), but is not limited thereto.

The mordant is a chemical agent that, when dyed with a dye (dye dye) that does not have a dyeing resistance to the toner, combines with the dye to produce an insoluble colored compound. It means operation. In other words, it refers to an operation of treating a dye that is not directly dyed with the dye due to lack of affinity for the dye to be treated with the agent to complete dyeing.

The salt material may be one or more extracts selected from the group consisting of a coloring material, for example, green tea, joiner, turmeric, safflower, chrysalis, and side, preferably the salt material may be tannin acid extracted from green tea. have.

In addition, the mordant may be one or more selected from the group consisting of alum, iron mortar, copper mortar, and tin salt, for example, a salt material to develop or fix the salt, preferably iron mortar (eg, sulfuric acid). Iron (FeSO ₄ )).

The ratio of each component contained in the cellulose powder may be appropriately determined in a range capable of producing a desired color. For example, when the cellulose powder is 100 parts by weight, 0.1 to 99.0 parts by weight of microcrystalline cellulose, 0.10 to It may include 20.0 parts by weight of salt and 0.01 to 10.0 parts by weight of mordant.

When using the green tea powder or cellulose powder embedded through the iron mordant as in the present invention, unlike the prior art using black iron oxide or a synthetic pigment as a color pigment, the degree of induction of irritation by using a natural pigment It can be significantly reduced, and the adhesion to the eyebrows and the application force are also excellent, so that the volume force can be improved.

In one preferred embodiment, the cellulose powder or green tea powder may be included in 3 to 30% by weight based on the total weight of the composition. If the cellulose powder is less than 3% by weight, the desired color may not be expressed. If the cellulose powder is more than 30% by weight, the pigments may not be uniformly dispersed and aggregated and aggregated so that they cannot be applied evenly and draw clean lines. .

In one preferred embodiment, the particle size of the powder may be 0.01 to 30㎛. This is because when the cosmetic composition having a particle size of more than 30 μm is applied to the finished cosmetic product and applied to the skin, there may be a foreign body feeling.

In some cases, the cosmetic composition may further include a dispersant. Since the particle size of the cellulose powder or green tea powder is about 15 μm, which is 2 to 3 times larger than iron oxide, a dispersant may be further included to improve dispersibility of the cellulose powder or green tea powder particles.

The dispersant may be sorbitan oleate or sodium metaphosphate, may be oil dispersed or dispersed, and may be included in an amount of 0.1 to 20 wt% based on the total weight of the cellulose powder or the green tea powder.

Dispersion of the cellulose powder or green tea powder particles may be performed at a low temperature, preferably at room temperature (20 to 30 ° C.), since the specific odor of salts, in particular, green tea, increases as the temperature increases.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the following Examples are provided to illustrate the present invention, and the scope of the present invention is not limited thereto.

 Test Example 1 Experiment of Stability (Light Resistance) of Cellulose Powder

Light resistance test consists of 10g of natural pigments commonly used in cosmetics (garia sulphate, safflower, cacao), green tea powder (KPT Co., Ltd. Starphere Obang black) and cellulose powder (KPT) 10g, respectively. During the 5 days left to check the color change every day.

Table 1 shows the light resistance test results of natural pigments.

(○: no change after 5 days, △: discoloration after 5 days, X: discoloration after 3 days)

As shown in Table 1, when using a natural pigment when not using the ultraviolet absorber Pasol # 1789, the light resistance is weak, it can be seen that the discoloration phenomenon appears. However, Green Tea Powder Co., Ltd.'s Starphere Obang Black and Cellulose Powder Co., Ltd., KPT's color resistance were maintained without discoloration or discoloration without using UV absorber, so it was found to have better light resistance than general natural pigments.

[Examples 1 and 2, Comparative Examples 1 to 5]

Table 2 shows the structures of Examples 1 and 2 and Comparative Examples 1 to 5 as preparation examples of mascara. The green tea powder and the cellulose powder used in Examples 1 and 2 were prepared by KPT Co., Ltd., and the volume was compared with Comparative Examples 2 and 3.

In Comparative Example 1, 10% by weight of cacao dyes of MSC Korea, Comparative Examples 2 and 3 used 10% by weight of cacao dyes, gardenia extract mixture (black M-3900), and 5% by weight of cellulose powder.

Comparative Examples 4 and 5 were prepared as a control for comparing the volume and the Examples 1 and 2, Comparative Examples 1 to 3 as a preparation example of mascara.

<Examples 1 and 2 and the manufacturing method of Comparative Examples 1 to 5>

1) The components 1-3 were heated at 70 degreeC.

2) Components 4-6 and 14-15 were heated to 80 degreeC.

3) Green tea powder and natural pigment (Nos. 9-12) were added to the mixture of 2) and stirred.

4) Components 7 to 8 were added to the mixture of 1), followed by emulsification with slowly adding 1) to 3), followed by cooling to 35 ° C.

5) The composition of 4) was filled in a mascara container.

Test Example 2 Usability (Volume Power) Comparison Test

The weight of the artificial eyelashes was measured before application, and the weight after application of each composition three times and 12 times was measured, and the results are shown in Table 3 below. On the other hand, the balance used in the experiment was measured using a scale displayed up to four decimal places. In addition, the correlation between the results of sensory evaluation and application amount obtained by actually using the mascara of Examples 1 and 2 and Comparative Examples 1 to 5 over 30 women in their 20s using five or more times a week was examined. Sensory evaluation is a scale of 1 to 14 points, the higher the volume function, the greater the score, and the higher the satisfaction of mascara.

◎: Very good (12 points or more), ○: Excellent (7 to 11 points), △: Normal (6 to 5 points), X: Poor (4 points or less)

In Examples 1 and 2, the coating amount was higher than that of Comparative Example 4, which was a control group, and the coating amount was similar to that of Comparative Example 5, and the sensory evaluation showed similar results.

However, in the case of Comparative Example 1 using only natural dyes (cacao dye), the application amount was 14 mg, which showed a low level of satisfaction with volume capability even in the sensory evaluation. The compositions of Examples 2 and 3 were measured to have a smaller coating amount than Example 1 which did not contain cellulose.

This is because the main component of the green tea powder is cellulose, formed in an amorphous shape, and large particles of 15 μm. It is a liquid natural pigment (cacao, gardenia mixed black pigment), or the composition according to the present invention than the iron oxide of the spherical shape and the particle size of 5 ~ 10μm has a good adhesion to the eyebrows is measured a large amount of coating.

As a result, the composition according to the present invention can be said to have a superior volume than the composition using the synthetic iron oxide while using a pigment derived from nature.

Test Example 3 Eye Stimulation Test

In order to test the eye irritation of the mascara prepared with the compositions of Examples 1 and 2 and Comparative Examples 1 to 5, a Hetcam-hen's egg test on the chorioallantoic membrane was performed. The test method used the test method defined in the CTFA safety testing guidelines. When white eggs were hatched at 37 ± 0.5 degrees and 55 ± 7% for 10 days, when erosion was observed, only the well-developed CAM (Chorioall Antoic Membrane) was selected. After that, eggshells and egg shells were removed and Comparative Examples 1 and 2 were compared. The test materials of 1 to 5 were spread thinly on a parafilm, and then applied to the CAM for a predetermined time (30 seconds) with the test materials facing downward, and the reaction was evaluated by washing the CAM with physiological saline. . The results were evaluated according to the evaluation criteria in the preliminary experiment of Table 4 below. The evaluation by HET-CAM was expressed as the sum <S> of each observation item H (Hemorrhage, bleeding), L (Lysis, lysis), and C (Coagulation, coagulation), and the S value was determined by the stimulation index.

The test was carried out six times, and the results are summarized in Table 6 below. In the following Table 6, the total stimulus score is less than 6 is "◎" as lightly irritating, "6" is 6 ~ 12 as "moderately irritating", and "12" is 16 as irritating. Δ "and greater than 16 are marked with" X "as Severely Irritating, respectively.

As shown in Table 5, compared with Comparative Examples 4 and 5 using the conventional iron oxide, Examples 1 and 2 according to the present invention showed a slight level of stimulation. Therefore, the composition of the present invention was confirmed that it can be used more safely without eye irritation than conventional products.

Those skilled in the art to which the present invention pertains will be able to perform various applications and modifications within the scope of the present invention based on the above contents.
