When applying lotion or milky lotion to the skin, these cosmetics are often applied to so-called puffs made of absorbent cotton or cotton spalace nonwoven fabric. Also, when removing make-up cosmetics such as lipsticks, foundations, eye shadows and mascaras, impregnating cosmetic liquids such as cleansing liquids into puffs, or absorbent cotton or absorbent cotton impregnated with cosmetic liquids such as cleansing liquids In many cases, a skin cleaning sheet made of a sheet, a cotton spunlace unemployed cloth or the like is used.
As described above, short fibers such as absorbent cotton, absorbent cotton sheet, and cotton spunlace nonwoven fabric are generally used in these cosmetic substrates and skin cleaning sheets in which a cosmetic solution is impregnated with a chemical solution. . This is because cotton is a cellulose fiber and has good liquid impregnation properties, natural fibers are considered to be less irritating to the skin, and because of short fibers, there is swelling and a soft touch. . However, since these base materials are short fibers, in a state impregnated with a cosmetic liquid containing a large amount of oil and solid oil, the short fibers fall off and adhere to the skin and re-contamination,
When the cosmetic liquid is not impregnated, there is a problem that the makeup removal effect is not sufficient because the fiber diameter is large.

Further, when the surface material of the cosmetic base material is a synthetic fiber such as polyester or nylon, there are problems such as low liquid retention compared to cotton and concerns about irritation to the skin.
In order to solve these problems, Patent Document 1 discloses a cosmetic cotton made of a regenerated cellulose long fiber nonwoven fabric. The regenerated cellulose long fiber nonwoven fabric is a nonwoven fabric produced by, for example, copper ammonia method rayon or viscose method rayon, and usually has a fiber diameter of about 10 to 16 μm. The regenerated cellulose continuous long-fiber nonwoven fabric by the copper ammonia rayon method is formed by self-adhesion of the fiber itself and fiber entanglement by high-pressure water flow. Is a very low material, and because it is composed of long fibers, it is characterized by very little re-contamination on the skin due to fiber dropping. However, the wiping property of make-up is almost the same as that of absorbent cotton, etc., and it does not satisfy the requirement for easier make-up removal. There was a problem.

Further, Patent Document 2 discloses a cosmetic wiper made of a nonwoven fabric in which ultrafine fibers having a single fiber fineness of 0.5 dtex or less occupy 20% or more of the surface area of the nonwoven fabric. However, in this cosmetic wiper, synthetic fibers such as polyethylene terephthalate and polypropylene are used as ultrafine fibers, so the liquid retention and irritation to the skin are improved, but still inferior to cellulosic fibers. It was.

The present invention will be specifically described below.
The cellulose long fiber nonwoven fabric referred to in the present invention is, for example, a regenerated cellulose continuous length in which a copper ammonia rayon stock solution is continuously spun onto a net by a flow-down tension spinning method and bonded and entangled by self-adhesion and hydroentanglement of the fiber itself. This refers to fiber nonwoven fabrics and purified cellulose long fiber nonwoven fabrics such as lyocell produced by the method disclosed in JP-T-2002-521585.
Cellulose long fiber nonwoven fabrics are composed of long fibers, so that the fibers do not drop out, and when used as a surface material, there is less contamination due to fiber adhesion to the human body than short fiber nonwoven fabrics such as cotton. Moreover, since it is excellent in a liquid retention property and physical irritation compared with the conventional synthetic fiber nonwoven fabric, it is preferable.
In addition, when the cellulose long fiber nonwoven fabric is a regenerated cellulose continuous long fiber nonwoven fabric, since a binder such as an adhesive resin is not used when forming the nonwoven fabric, it is preferable because it is excellent in safety. In addition, self-adhesion is preferable because of high form stability.

The cosmetic base material of the present invention has a cellulose long fiber nonwoven fabric surface, and is 60% or more, preferably 80% or more, most preferably 100% of the number of fibers constituting at least the surface of the nonwoven fabric.
Is made of long cellulose fibers having a fiber diameter of 2.9 to 7.1 μm. The fiber diameter here refers to the diameter of the fiber that is in focus when observed at a magnification at which the single fiber is about 1 cm in the electron micrograph of the nonwoven fabric surface. In the present invention, the fiber diameter is measured at an arbitrary 200 points on the surface of the nonwoven fabric, and the abundance ratio is 60% or more, that is, 120 points or more are composed of fibers having a fiber diameter of 2.9 to 7.1 μm. It means being. When 60% or more of the number of long cellulose fibers forming at least the surface of the nonwoven fabric has a fiber diameter of 2.9 to 7.1 μm, it constitutes a nonwoven fabric as compared with those having the same basis weight and a fiber diameter exceeding 7.1 μm. Since the number of fiber entanglement points and self-adhesion points increases, the morphological stability when wet is drastically improved. Further, in the case of the regenerated cellulose continuous long-fiber nonwoven fabric, the scouring property of the single yarn is improved by reducing the fiber diameter, the whiteness is increased by irregular reflection, and the clean feeling as a cosmetic base material is improved. In addition to this, the surface area increases, and the contact area with the wiping surface also increases, so that the wiping performance also increases dramatically. In addition, when the fiber diameter is within this range, the water infusion performance is improved by capillary action.

In order to obtain a cellulose long fiber nonwoven fabric having a fiber diameter of 2.9 to 7.1 μm, for example, when a regenerated cellulose long fiber nonwoven fabric is obtained using a copper ammonia method rayon stock solution, the diameter of the spinning nozzle for spinning the stock solution is conventional. It can be suitably obtained by making it smaller, adjusting the viscosity of the stock solution and the temperature of the stock solution, controlling the coagulation rate, and taking a higher draw ratio than before.
If the number of fibers having a fiber diameter of 2.9 to 7.1 μm is less than 60% among the fibers constituting at least the surface of the nonwoven fabric, not only the shape stability and whiteness when wet are reduced, but also the wiping property is lowered. There are things to do.

The cellulose long fiber nonwoven fabric in the cosmetic base material of the present invention preferably has a wet form retention of 80% or more, more preferably 90% or more. The wet form retention rate here is measured by the following method. A schematic diagram of the measuring apparatus is shown in FIG. A sample is prepared in a size of 5 cm × 12 cm so as to be vertically long in the machine axis direction of the nonwoven fabric, and a measurement part is created by marking the center part of the upper and lower parts of 1 cm. Pure water of 10 times the sample weight W1 is uniformly applied to the sample. 1 cm above and below the sample is sandwiched between sample holding plates and fixed. 30 wt% of the load of the sample weight W1 per 1 m 2 (Sample holding plate is 10% by weight of W1, load to original which was added) was subjected dividing weigh after hanging for 30 sec (at the bottom of the sample holding Remove the plate), 30
The length L of the measurement part is measured after 2 seconds. The initial sample length is 10 cm (length between sample holding plates), and the wet form retention rate is calculated by the following equation.
Wet form retention rate (%) = (10− (L−10)) / 10 × 100
The wet form retention rate greatly correlates with the handleability at the time of makeup wiping in a wet state impregnated with a cosmetic liquid. If the wet form retention rate is less than 80%, the surface material may be distorted when the make-up is wiped in a wet state, and the handleability may be reduced, or the surface material may be broken and the batting etc. may come into contact with the body surface to recontaminate the wiping surface.

Add 10 ml of (red) to make an evaluation solution. The evaluation liquid is injected into a burette having a tip diameter of 0.7 mm. The viewlet and camera are set as shown in FIG. The camera is a fixed type, the burette is a lateral movement type with a fixed height, the camera position is set 10 cm above the sample surface, and the burette is set 5 cm above the sample surface. The evaluation solution is dropped on a drop (0.01 ml) of the sample, and at the same time, the burette is moved to the side to take a photograph of the diffusion state after 10 seconds. At this time, a JIS standard metal scale is placed on the surface of the sample so that it can be converted into an actual diffusion area as shown in a photograph. The diffusion area is obtained from the photograph by image processing or the like.

The diffusion area is related to the fiber diameter and the voids between the fibers. When the fiber diameter is within the range of the present invention, the diffusion area is improved by capillarity from those exceeding this range. Diffusion area is 400m
If m 2 or more, the efficiency of a small amount of cosmetic liquid cosmetic liquid for spreading significantly to the surface even improved.
When the fiber diameter is below this range, the diffusion area is improved, but the strength of the single fiber is reduced, the fiber is cut at the time of wiping, and the amount of fiber remaining on the wiping surface increases, so that it cannot be used in actual use.

Further, the liquid diffusion state coefficient is measured using the above-mentioned photograph at the time of liquid diffusion area measurement. Usually, since the liquid diffuses into an ellipse, the major axis a and minor axis b of the ellipse are measured. The liquid diffusion state coefficient c is calculated by the following method.
Liquid diffusion state coefficient c = b / a
The liquid diffusion state coefficient is a coefficient indicating the diffusion state when the liquid is dropped, and becomes circular when diffused in the same state in any direction. In this case, the liquid diffusion state coefficient is 1. Since the liquid diffusion state of the cleansing base material is considered to be isotropic from the viewpoint that it is not necessary to change the production method and the direction of use depending on the shape, the liquid diffusion state coefficient is 0.65 to 1.35. Is more preferable, and 0.75 to 1.25 is more preferable. The liquid diffusibility can be controlled by adjusting the orientation state of the fibers constituting the substrate. In the case of long-fiber non-woven fabrics, many fibers tend to be oriented in the machine axis (MD) direction due to the characteristics of the manufacturing method. For example, when the fibers are shaken off on the net, vibration is given in the direction perpendicular to the machine axis (CD). Thus, it is possible to control the orientation state of the fiber.

The cosmetic base material of the present invention can be used alone as a puff or the like. For example, the cosmetic base material of the present invention is used as a surface material, and the structure is sandwiched between the base material and has a short fiber or a crimp. A puff may be formed by using compressed fibers or the like as batting. Filling is effective for retaining bulkiness, softness, and cosmetic liquid. Such a puff can be obtained by arranging the base material and the batting as described above, and performing thermal bonding or pressure bonding. In the case of heat bonding, a heat-sealable low melting point fine powder may be sprayed and fixed on the back surface of the wiping surface, or a heat-sealable fiber may be used for the batting. In any form, if the wiping surface is composed of the base material for makeup of the present invention, the effect of removing dirt, the effect of removing makeup, and the form retainability when wet are remarkably improved as compared with the conventional product.

The cosmetic base material of the present invention is also optimal as a base material for so-called wet make-up products and skin cleaning sheets, which are supplied in the state of being impregnated with a chemical solution for cosmetic removal.
The skin cleaning sheet is required to have a function of sufficiently retaining a chemical solution, a wiping property, and a shape retaining property at the time of wiping, but the cosmetic base material of the present invention has the above-described functionality for the reasons described above. It is a very effective substrate that satisfies all.
As the chemical solution impregnated in the skin cleansing sheet comprising the cosmetic base material of the present invention, a chemical solution used for ordinary make-up wet products may be used. For example, the chemical solution includes an active agent for makeup removal, for example, a lipophilic emulsifier such as G lauric acid PEG-12, a moisturizer, an antibacterial agent, an antiseptic,
A fragrance | flavor etc. may be contained in water or alcohol aqueous solution.

Further, the skin cleaning sheet is preferably supplied in a state of being impregnated with 100 to 400% by mass of a chemical solution. More preferably, the state is impregnated with 150 to 350% by mass of a chemical solution.
When the amount of the impregnating chemical solution is less than 100% by mass, the chemical solution evaporates during storage, and the wet state may not be maintained, or the wiping effect during wiping may be reduced. If the amount of the impregnating chemical solution exceeds 400% by mass, the chemical solution may drip at the time of use and stain clothes or the like, and the cost of the chemical solution may increase, resulting in an economical problem.
