Description

  The present invention relates to a liquid cosmetic composition for eye makeup suitable for an eyeliner, eyeshadow, eyebrow, etc. suitable for point makeup such as around the eyes, and more specifically, it does not blur on the skin even when applied, and it is bright. The present invention relates to a liquid cosmetic composition for eye make-up, which has no unevenness in color, has a low viscosity with less dripping (bleeding), can draw a bright glittering line, and has a good makeup retention.

  Conventionally, non-aqueous type and emulsifying type cosmetics have been known as point-makeup cosmetics for the area around the eyes, etc., but in recent years, water-based liquid cosmetics have been spread from the viewpoint of spreadability during application and long-lasting makeup. The number of ingredient compositions is increasing.

The water-based liquid cosmetic composition includes, for example, [1] an aqueous thickening / gelling agent and a pearl luster powder, which is an aqueous point makeup cosmetic (for example, a patent Reference 1), [2] A liquid cosmetic comprising at least an inorganic pigment, a dispersant, a film-forming agent, and water, wherein the dispersant is acrylic acid, methacrylic acid or their (C _{1 to} C ₄ and C ₈ ) is a homopolymer or copolymer having one or more compounds selected from the group consisting of alkyl esters as raw material monomers, and the film-forming agent is acrylic acid, methacrylic acid, or their (C It is ₁ -C ₄ and C ₈₎ alkyl ester, or emulsion of homopolymer or copolymer of one or more compounds selected from among styrene as a raw material monomer A liquid cosmetic (for example, refer to Patent Document 2), [3] a cosmetic composition containing a pigment composition containing an inorganic pigment or an inorganic filler and a phosphoric acid ester having a specific structure (for example, Patent Document 3). 15) to 35% by mass of an acrylic acid-based polymer obtained by polymerizing one or more monomers of the group consisting of acrylic acid, methacrylic acid, acrylic acid ester, and methacrylic acid ester, and a solid oil content of 5). To 30% by mass, fluid oil content 2 to 20% by mass, 12-hydroxystearic acid 0.2 to 5% by mass, solid fatty acid other than 12-hydroxystearic acid 0.5 to 4% by mass, and surfactant. An oil-in-water emulsion cosmetic containing 1 to 10% by mass and water is known (see, for example, Patent Document 4).
On the other hand, examples of the cosmetics using fermented cellulose include, for example, fermented cellulose in the cosmetics in order to suppress the stickiness when a cosmetic such as cream or gel is applied to the skin and provide a cosmetic with a good feeling of use. Is added to improve the dispersibility of the fermented cellulose dispersion, and cosmetics characterized by reduced stickiness (see, for example, Patent Document 5), hydroxyethyl cellulose and / or guar gum. A dispersibility improver (see, for example, Patent Document 6) to be contained is known.

However, the water-based liquid cosmetic compositions shown in Patent Documents 1 to 4 described above were used for an applicator having an application part using brush tips made of an ultrafine fiber bundle suitable for point makeup such as around the eyes. In this case, since the whole brush is thin, the amount of liquid retained is extremely small, and there is a problem that the glittering line is blurred and it becomes messy, and when the viscosity is low to increase the amount retained, However, problems such as dripping (dropping) have occurred. Further, with the particle size of the tabular pigment that can obtain the glittering line as in the conventional case, the tabular pigment having a high specific gravity settles down, and the difference in hue between the long and narrow brush tips causes the unevenness in the glittering line. The current situation is that there is a problem such as (difference in glitter).
Further, the cosmetics and the like using the fermented cellulose described in Patent Documents 5 and 6 above have a problem / objective to suppress stickiness when a cosmetic such as cream or gel is applied to the skin. In order to improve the dispersibility of the fermented cellulose dispersion liquid, hydroxyethyl cellulose or the like is used in combination, and even when the present invention is applied, it is not blurred on the skin, there is no color unevenness, and there is little dripping (bleeding). A liquid cosmetic composition having a low viscosity and capable of drawing a bright glittering line is different in its purpose / problem and technical idea (configuration and its effect).

It is characterized by containing an aqueous emulsion of an acid polymer, fermented cellulose, a coloring material containing at least a tabular pigment, and water.

The aqueous emulsion of the acrylic acid polymer used in the present invention is obtained by polymerizing one or more monomers selected from acrylic acid monomers, methacrylic acid monomers, acrylic acid ester monomers, and methacrylic acid ester monomers. There is no particular limitation as long as it is an aqueous emulsion having a glass transition point of 20 ° C. or lower, and various aqueous emulsions can be used.
The aqueous emulsion of acrylic acid-based polymer used is used as a film-forming agent, and preferably has a glass transition point (Tg) of -20 ° C or more to 20 from the viewpoint of film-forming property and elasticity of the formed film. It is desirable to use an aqueous emulsion having a temperature of ℃ or less. If the glass transition point is higher than 20 ° C., the elasticity and film forming property of the dried cosmetic material are deteriorated and the durability of the makeup is deteriorated, which is not preferable.
In the present invention, the glass transition point (Tg) was measured as follows. First, a resin was formed into a lacquer shape, a lacquer-like resin was formed into a film, and then the solvent was dried to form a film. The differential scanning calorie was measured by heating the film-formed acrylic resin from -20 ° C to + 150 ° C at a heating rate of 10 ° C / min using a differential scanning calorimeter (DSC) manufactured by Rigaku Corporation. The obtained endothermic curve was differentiated to obtain an inflection point, and this inflection point was determined as Tg.

As shown in FIG. 4, in the brush 23a having a substantially star-shaped cross section, the dimension Lal between the concave portions facing the tip of the convex portion is 120 μm to 200 μm, and the convex portion facing the tip of the convex portion is opposite. The dimension La2 between the parts is preferably in the range of 140 μm to 250 μm.
It is preferable that the dimension La1 be small and the dimension La2 be large, because the irregularities formed on the outer peripheral surface of the brush can be deepened (large) and a large amount of coating liquid can be retained. On the other hand, when the dimension Lal is made small and the dimension La2 is made large, the stiffness of the brush becomes weak and the application cannot be performed comfortably. Therefore, it is preferable to form it within the above range.

Further, as shown in FIGS. 5 and 6, in the case of the brush 23b having a substantially eyebrows-shaped cross section, the cross-sectional shape is such that FIG. 5 is a shape in which two circles having substantially the same shape are connected. FIG. 6 shows a shape in which two circles having substantially the same shape are connected by a rectangle.
Further, it is preferable to increase the depth dimension (difference between Lbl and Lb2) of the concave portion formed on the outer peripheral surface of the substantially brow-shaped brush 23b since the amount of the coating liquid can be increased.
However, if the connecting portion length dimension Lb2 is too small, the connected state of the two circles may be damaged, and if it is damaged, the brush will have a normal circular cross section and the amount of the coating liquid cannot be increased. Not preferable.
Therefore, Lbl and Lb3 (dimensions to the axis of line symmetry) are 70 μm to 200 μm, Lb2 is 20 μm to 190 μm, Lb4 is in the range of 80 μm to 390 μm, and more preferably Lb1 and Lb3 are 100 μm to 100 μm. 150 μm, Lb2 is 50 μm to 100 μm, and Lb4 is in the range of 150 μm to 300 μm, the fibers are unlikely to be bifurcated when the tip of the brush is tapered, and a recess is likely to remain in the tapered region. Preferably.

The brush 23 is composed of a plurality of types of brushes having different cross-sectional shapes, for example, the above-mentioned brush having a substantially star-shaped cross-section and a brush having a substantially eye-shaped cross-section.
Using a plurality of types of brush hairs having different cross-sectional shapes in this manner is a preferable mode for the following reasons.
(1) When brushes having the same cross-sectional shape are used, the concave and convex portions formed on the outer peripheral surface are fitted to each other to partially or entirely fill the concave portion formed on the outer peripheral surface of the brush, It reduces the voids (gap) between the bristles and reduces the amount of coating liquid contained in the brush. On the other hand, when a plurality of types of brushes having different cross-sectional shapes are used, it is difficult to fit the uneven portion formed on the outer peripheral surface, and the reduction of the gap (gap) between the brushes is suppressed.
(2) Further, when the brush having the same cross-sectional shape is used and the uneven portion formed on the outer peripheral surface of the brush is enlarged, the stiffness of the brush tends to be weak. On the other hand, by using a plurality of types of brushes with different cross-sectional shapes, even when the irregularities on the outer peripheral surface of one brush are made large, the stiffness of the brush can be given by the other brush. Therefore, it is possible to obtain a suitable coating property.

  The thickness of the fiber used for the brush is not limited to this, but it is 0.05 at the minimum equivalent diameter of the cross section perpendicular to the axis of the fiber. Short fibers having a length of about 0.3 mm and a length of about 5 mm to 100 mm are used.

Further, as shown in FIGS. 7 and 8, concave portions 23a1 and 23b1 may be formed on the surface portions of the brush hairs (synthetic resin fibers) 23a and 23b. In this way, since the concave portions 23a1 and 23b1 are formed on the fiber surface in the longitudinal direction (axial direction) from the tips of the brushes 23a and 23b made of synthetic resin, the brushes (synthetic resin fiber) 23a. , 23b, many small voids are formed.
As a result, the coating liquid permeates into these voids, and a large amount of liquid is retained between the brushes (fibers made of synthetic resin).

The size of the recess formed on the surface of such a fiber is not particularly limited, but from the viewpoint of liquid retention, the recess generally has a depth of 20 μm or less, particularly 5 to 10 μm. It is preferable that the average pitch of the irregularities is in the range of 0.1 to 0.5 mm.
Further, even when recesses are formed on the surface portions of the brushes (synthetic resin fibers) 23a and 23b, the equivalent diameter of the section perpendicular to the axis of the recesses is 0.05 mm or more.

The recesses 23a1 and 23b1 may be formed in a spiral shape continuously from one end side to the other end side of the brush (synthetic resin fiber) 23a and 23b.
Further, a convex portion may be formed on the surface portion of the brush (synthetic resin fiber) 23a, 23b, and the convex portion has a spiral shape from one end side to the other end side like the concave portion. It may be formed continuously. In general, it is preferable that the height of the protrusions is 20 μm or less, particularly 5 to 10 μm, and the average pitch of the protrusions is 0.1 to 0.5 mm.

It should be noted that the brush hair (textile made of synthetic resin) is made to contain titanium oxide or the like to form convex portions on the surface portions of 23a and 23b, and a gap is formed in the fiber gap to suppress adhesion of the fiber gap. Good.
Further, the brush 23 may be composed of a plurality of types of brushes having different cross-sectional shapes, and is limited to brushes having a substantially star-shaped cross-section and brushes having a substantially eye-shaped cross-section. It is not something that will be done. For example, it may have a substantially cross shape, a substantially triangular shape, a substantially Y shape, a substantially semicircular shape, a substantially rectangular shape, or the like, and is not limited to two types, and two or more types of irregular cross-sections may be used. You may mix the brush.
This mixing ratio is appropriately set depending on the application of the brush, particularly the required degree of holding property. For example, in the case of mixing a brush with a star-shaped cross-section and a brush with a brow-shaped cross-section. The mixing ratio is preferably 80:20 to 20:80 from the viewpoint of the effect of substantially improving the holding power.
Further, in the above embodiment, all the fibers of the brush 23 have a cross section other than circular, but a mixture of a circular cross section and each of the irregular cross sections (preferably a mixing ratio of 50% or more) is mixed. The cross-section may be one (single).

  In the liquid makeup applicator A for eye makeup configured as described above, when a plurality of types of brushes having different cross-sectional shapes having different cross-sectional shapes are used for the brush to be the application portion, the gap (space between the brushes) ) Is suppressed, and the firmness of the brush can be imparted. Moreover, the liquid cosmetic composition of the present invention does not blur on the skin even when applied on the skin, and falls off (drips). ), A low viscosity, and a glittering line with no color unevenness that can be drawn deeply. Therefore, the synergistic effect of the properties of the liquid cosmetic composition and the structural properties of the liquid cosmetic applicator results in a coating liquid. It is possible to obtain a liquid cosmetic applicator that can be applied comfortably by sufficiently containing the liquid cosmetic composition to be contained in the brush.

Is mentioned. In order to prevent the liquid cosmetic material 50 pushed out from the tank portion 51 from falling off from the pen tip or the air hole when the air inside the tank portion 51 expands due to a temperature rise or the like, the front portion of the tank portion 51 is temporarily suspended. A sheet-shaped body (ink storage body, collector member) 52 for storing is built-in, and a pen tip (brush tip) 53 as a coating body is provided at the tip of the collector member 52. There is. As the brush-shaped pen tip (brush tip) 53, the brush tip 23 having the irregular cross section used in the liquid cosmetic applicator A can be used.

The liquid cosmetic material is discharged from the tank portion 51 to the pen tip 53 by applying the liquid cosmetic material 50 from the tank portion 51 via a relay core 55 provided with a coating liquid flow path 54 attached to the central hole of the collector member 52. It is performed by leading out to the pen tip 53 which becomes a copy.
In FIG. 9, reference numerals 56 and 57 are holder members, 58 is a rear shaft body fixed to the rear portion of the tank portion 51, and 59 is a cap having an inner cap. Further, the liquid cosmetic may be led out by directly disposing the rear portion of the pen tip 53 inside the tank portion 51 without interposing the relay core 55.
By removing the cap 59, the liquid cosmetic applicator B of this form can be used in the same manner as the liquid cosmetic applicator A.

FIG. 10 shows the liquid cosmetic composition for eye makeup of the present invention used in a batting type liquid cosmetic applicator.
The liquid cosmetic applicator C of this form has, for example, as shown in FIG. 10, an inner shaft 61 inside a cosmetic body 60, and the inner shaft 61 is impregnated with the liquid cosmetic composition of the present invention. The impregnated body 62 made of the filled batting or the like is accommodated, and the tip end side of the impregnated body 62 is an application body 63 composed of a brush ear having a modified cross section used in the liquid cosmetics application tool A for applying the liquid cosmetics. And a tail plug 64 is fixed to the rear end of the inner shaft 61. Incidentally, 65 is a cap body having an inner cap portion 66. The liquid cosmetic applicator C of this form is used by removing the cap 65.
