Description

Detailed Description of the Invention [Industrial Field of Application] The present invention uses a synthetic resin emulsion as a film-forming main ingredient, and amorphous silicic acid produced by a wet process (hereinafter referred to as wet process silica) and/or a synthetic resin emulsion. Eye make-up cosmetics characterized by containing regular-shaped silicon salts as an essential ingredient, more specifically, having excellent dryness of the coating film, water resistance, cosmetic effect, and long-lasting usability, and stability. It also provides good eyeliner, mascara, eyebrow, etc.

The present invention improves the drying speed of the coating film, coating strength, adhesion to the skin, eye hair, etc. in film-forming eyeliners, mascaras, eyebrows, etc., and makes it easy to adjust these. The purpose is to make it possible.

[Prior Art] Conventionally, liquid eyeliners, mascaras, and the like include film-forming types that use synthetic resin emulsions as film-forming main ingredients. This type includes a film type in which pigments are dispersed in an aqueous system, and a solid or semi-solid type to improve usability such as stretchability, uniformity of the coating film, and flexibility of the coating film. There are also emulsion film types that contain liquid oils, mucilages, surfactants, agents, etc.

Film-forming products form an insoluble film after application and drying, so they have excellent water resistance against sweat and tears, adhesion to the film, ease of removing makeup, and do not stain the area around the eyes. It is in good condition.

However, although it forms a water-insoluble film, when it gets wet with water, phenomena such as tearing and peeling of the film occur, and the strength of the film against water and the durability of its adhesion to the skin are not fully satisfactory. Furthermore, it is not water resistant enough to withstand use during intense sports.

Furthermore, regarding the drying speed of the coating film, which is an important quality requirement, the main determining factors are the properties of the synthetic resin emulsion used as the film-forming main agent, its blending amount, and its blending ratio with water. Therefore, in order to increase the drying speed, it was necessary to adjust the amount of the synthetic resin emulsion and water. However, the drying rate is too fast, causing an increase in viscosity, leading to decreased usability and changes in product characteristics, and adjustment of the drying rate is naturally limited and extremely difficult.

[Problems to be Solved by the Invention] As described in L, conventional film-forming eyeliners, mascaras, etc. have good usability and functionality, but they have poor water resistance, film strength, and skin , adhesion to the hair, drying speed, etc., are not always sufficient, and these controls are strongly affected by the two components of the synthetic resin emulsion and water, which can lead to decreased usability and product characteristics. 6 In addition, there is a strong demand for improvements in the drying speed of the paint film, the usability of the coating, the water resistance against sweat and tears, the durability of the cosmetic effect, etc. I was about to leave.

In view of the above points, the present invention provides, without changing the product characteristics,
This aims to solve problems such as drying speed, water resistance, coating strength, and adhesion to the skin, eye hair, etc. by this,
The goal is to expand product characteristics and address quality issues.

Means for Solving Problem c] In order to solve the above problem, the inventors of the present invention, as a result of intensive research, have found that in eyeliner 7, mascara, eye brow, etc. containing a synthetic resin emulsion, wet process silica and/or By adding amorphous silicates, we succeeded in significantly improving the above-mentioned problem, and based on this knowledge, we completed the present invention.

That is, the present invention provides film-forming eye make-up cosmetics such as eyeliners, mascaras, and eyebrows that contain synthetic resin emulsions as constituent ingredients, in which wet-process silica and/or amorphous silicates are dispersed. By taking advantage of its properties, the drying speed is rapid, and it has excellent water resistance, film strength, and adhesion to the skin, villi, etc. Furthermore, by changing the blending amount appropriately, the drying speed can be improved. It is characterized in that adjustment and viscosity adjustment can be easily made, and product features can be expanded.

The essential components used in the present invention will be explained below.

Examples of the synthetic resin emulsion include synthetic resins such as vinyl polymers such as poly(meth)acrylic ester, polyvinyl acetate, polyvinyl chloride, and polyethylene vinyl, and synthetic rubbers such as polyisobutylene. Examples include emulsions. These alone,
Can it be a combination? , is not particularly limited.

The wet process silica used in the present invention is silicic acid (amorphous silica) produced by a wet process. In addition, silicates include inorganic salts of silicic acid (amorphous silicate) or inorganic salts of silicate aluminate (amorphous aluminosilicate). Inorganic salts of silicic acid include, for example, aluminum silicate, calcium silicate, magnesium silicate, and hydrates thereof. In addition, examples of the inorganic salts of aluminosilicate include magnesium aluminate (meth)silicate, calcium aluminate (meth)silicate, dimagnesium aluminate (meth)silicate, and dimagnesium aluminate (meth)silicate. There are calcium, magnesium, mixed salts of calcium, or hydrates thereof. These may be used alone or in combination, and can be selected and used as appropriate.

hw, wet process silica and silicates have an amorphous crystal structure (amorphous) due to their woody nature, and are fine powder particles that usually form secondary particles and have a large specific surface area. It is something.

These particles have many hydroxyl groups inside and on their surfaces, and are porous in some cases, so they retain structural water and adsorbed water and have a high hygroscopic property.

In the present invention, the primary particle size of wet-processed silica and silicate is in the range of about 1+n to 10p, more preferably 10mp to 1, and the average particle size of the powder's secondary particles is The diameter is in the range of 0.5 to 20, more preferably 0.5
It is best to use ultrafine particles with a specific surface area of 50 to 500 m'/g.

In addition, the amount of wet process silica and/or silicates is 0.1 to 15% by weight, but 0.2 to 1% by weight.
Approximately 0% by weight is preferable in terms of usage characteristics. In other words, when used in this range, the viscosity of the product system does not increase or solidify, and the fluidity is good and the viscosity can be easily controlled.
It has excellent usability and has almost no effect on the product system. However, if it is less than 0.1% by weight, the expected effects of the present invention will not be obtained and the objective will not be achieved.

Furthermore, in addition to the above ingredients, the eye makeup cosmetic of the present invention includes pigments, powders, oil and fat raw materials, surfactants, thickeners,
Solubilizers, antioxidants, preservatives, fragrances, etc. can be added as appropriate.

The eye makeup cosmetics of the present invention, such as eyeliner, mascara, and eyebrow, are constructed as described above, and are not particularly limited, but are of a film-forming type, and are composed of a synthetic resin emulsion and water, and pigments are dispersed therein. This includes the emulsion film type, which is a type in which a solid, semi-solid, liquid oil, surfactant, etc. are added to this and is used in combination with an emulsion type. [Function] Since the eye makeup cosmetic of the present invention is characterized by the above-mentioned structure, wet process silica and/or amorphous silicates are dispersed in a synthetic resin emulsion system. Payment is made using the characteristics.

Wet process silica and amorphous silicates.

They are extremely fine particles, have a large surface area, and have many hydroxyl groups on their surfaces, so they have high hygroscopic properties and good affinity with water.

Therefore, it has good dispersibility in water systems, has little thickening effect in product systems, and can be used to adjust the viscosity of eye makeup cosmetics.
It has excellent chicken-tropy properties, and exhibits excellent properties for the purpose of improving film reinforcement, adhesion, and suppressing gloss through interaction with synthetic resin emulsions in decorative coatings. be.

[Effect] Using the eyeliners of Examples [1] to [4] obtained by the present invention and the eyeliners of Comparative Examples [1] to r5J,
The viscosity on the next day after adjustment was measured using a B-type viscometer. The results are shown in Table 2.

(Leaving space below) Table 2 Viscosity measurement results As is clear from Table 2, the product of the present invention containing wet process silica or magnesium aluminate silicate, which is a type of amorphous silicate, does not contain dry process silica. Compared to the compounded comparative product, the viscosity increase is small and the product is good.

In addition, dry process silica significantly changes the viscosity depending on the amount blended, whereas wet process silica or magnesium aluminate silicate has only a slight effect on viscosity changes. Therefore, wet process silica and silicates can be blended without impairing the viscosity characteristics and product properties of the product, and the range in which they can be blended is wide and can be selected as appropriate.

Next, regarding the characteristics of the eye makeup cosmetic of the present invention,
Example [1], [3] and Comparative Example H], [4
] using the following products to evaluate the water resistance, drying speed, film strength, adhesion, stability over time (viscosity increase over time), uniformity of the paint film, and matting effect (suppression degree) of the paint film. The results are shown in Table 3.

The measurement and evaluation methods are as shown below.

(1) Water resistance test - Take an appropriate amount of each sample onto a glass plate, use a doctor blade to form a film of a certain thickness, and after drying, immerse in purified water and shake. For each sample, change the peeling time of the coating film and compare and evaluate.

(2) Drying test A film is formed in the same manner as in (1), and the drying time is evaluated by touch and compared for each sample.

(3) Coating film strength test After drying, the film prepared in the same manner as in (1) is peeled off from the glass plate to obtain a film.

The tensile strength of this film is measured using a rheometer and compared for each sample.

(4) Adhesion test Each sample was applied to the back of the hand, and after drying, the number of times of rubbing was determined.
Compare and evaluate.

(5) Viscosity measurement method Each sample is placed in a 501 airtight container, left to stand in a constant temperature bath at 30°C, and the viscosity is measured using a B-type viscometer immediately after production and one week later. Evaluate based on the degree of viscosity change.

(6) Evaluation of film uniformity and gloss The coating film prepared in the same manner as in (1) was visually observed and evaluated.

Table 3 Product Characteristics Evaluation Results Bad As is clear from Table 3, the eyeliner of the present invention had excellent water resistance, film strength, drying speed, and good adhesion. Regarding the uniformity of the film, in comparison example [41] using dry process silica, unevenness was observed on the film surface.
The product of the present invention has a uniform film, and has less gloss.
It was in good condition. Furthermore, the product of the present invention can, over time,
The viscosity did not increase and the stability was excellent.

As described above, the eye makeup cosmetics obtained by the present invention, i.e., eyeliners, mascaras, eyebrows, etc., have better drying speed, water resistance, film strength, and adhesion to the skin, hair, etc. than conventional products. In addition, the cosmetic film has an appropriate gloss, forms a uniform film, and is long-lasting. Moreover, it does not thicken over time and has excellent stability. Therefore, according to the present invention, it has become possible to obtain eyeliners, mascara, and eyebrows with excellent quality such as functionality, usability, and stability.

Furthermore, adjusting the drying rate has conventionally been difficult because it has mainly relied on controlling the composition of synthetic resin emulsions and water, which changes the product properties. By adding , this can be easily achieved, and by appropriately changing the blending amount, the desired sound can be set. This is because the addition of wet process silica and amorphous silicates, or changes in their blending amounts, have little effect on the fluidity properties of the product. Therefore, we can expect an expansion in product range.
