Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a skin which has an excellent ability to retain an aqueous detergent, has a high detergency against makeup stains and sebum stains, and has an excellent skin feel during use and a finished feeling after use. The present invention relates to a cleaning sheet.

[0002]

2. Description of the Related Art
To remove makeup stains such as lipsticks, foundations, eye shadows, mascaras, etc., use gel-based cleansing agents, cleansing creams,
Cleansing oil and the like are used. However, these cleansing agents mainly composed of an oily base have a strong feeling of oiliness and stickiness. Therefore, after washing with the cleansing agent, it is necessary to further wash with a face wash or the like.

[0003] On the other hand, in order to solve these feelings of use (oiliness and stickiness), a type of facial cleanser having both cleansing and face washing is used. There is a problem that, when rinsing is slow, nucleation due to a polymer that forms a gel is large. In addition, those that are used by whipping are diluted with water at the time of whipping, and thus do not exhibit sufficient detergency for makeup cosmetics. The liquid type has a drawback in that the cleaning agent flows from the face during face washing and the operability is poor.

[0004] In addition, there is also a method of wiping with a tissue paper or the like using a low viscosity liquid for removing makeup,
In this case, the dirt cannot be efficiently adsorbed on the tissue paper, and both sides of the tissue paper are immediately stained due to the back-inside. Furthermore, the cleaning power for sebum dirt such as solid dirt clogging the pores is not enough, and rubbing the skin strongly with tissue paper to make this detergency sufficient and methyl will damage the skin. This is not a preferable means, and therefore, there is a problem that a satisfactory detergency cannot be obtained.

[0005] In recent years, various proposals have been made on the removal of sheet-like make-up because it does not require water and is simple. For example, Japanese Patent Application Laid-Open Nos.
No. 279226, No. 11-49641, No. 6-305
No. 931, No. 7-233023, No. 2-104511
And JP-A-4-5224 and JP-A-4-154717. However, each of the makeup removers has a disadvantage that the cleaning power is insufficient or the feel after use is sticky or slimy.

[0006] In particular, Japanese Patent Application Laid-Open No. 11-21121 discloses that
A sheet for skin washing containing a sheet (a nonwoven fabric made of a natural fiber having an average basis weight of about 20 to 120 g / m ² or the like) containing a nonionic surfactant of HLB 10 to 16, polyhydric alcohol or glycol ether, and water. JP-A-11-49641 discloses that the cellulose content is 50% by weight or more and the average basis weight is 2%.
A non-ionic surfactant (HLB 10-1) is added to a non-woven fabric of a water entanglement having 0 to 120 g / m ² , an average fineness of constituent fibers of 3 d (denier or less), and a dry reflectance of 45% or more.
6), a skin-cleaning sheet containing water has been proposed, which has high detergency, low irritation, dirt is hard to pass through, and has a good feel upon use. However, these skin cleaning sheets have a problem that it is difficult to say that the makeup removing effect is sufficiently satisfactory, and that the sheet has a poor skin contact, and there is a concern that the skin may be damaged when the makeup is removed. Therefore, development of a higher quality skin washing sheet in which the above-mentioned problems are improved is desired.

The present invention has been made in order to meet the above-mentioned demands, and has an excellent ability to retain an aqueous detergent, has a very high detergency for makeup stains and sebum stains, and
An object of the present invention is to provide a skin cleaning sheet that is excellent in skin feel during use and finished feeling after use.

[0008]

Means for Solving the Problems and Embodiments of the Invention The present inventors have conducted intensive studies in order to achieve the above object, and as a result, a water-based cleaning composition was applied to a nonwoven sheet having specific characteristics as described later. Incorporation of a water-based detergent composition provides excellent retention performance of the aqueous detergent composition, exerts extremely high detergency against oily stains such as make-up and sebum, has a good sheet contact with the skin, and provides a feel during use. Further, the present inventors have found that a skin-cleaning sheet which is excellent in the finished feeling after use and has excellent usability without scratching the skin when removing makeup and excellent in usability can be obtained, and thus completed the present invention.

That is, the present invention relates to a hydroentangled nonwoven fabric comprising cellulose fibers and synthetic fibers, wherein the ratio of the average fineness of the cellulose fibers to the average fineness of the synthetic fibers constituting the nonwoven fabric is 2.5 to 12, A non-woven fabric having a mass ratio of fibers to synthetic fibers of 80/20 to 10/90 and an average inter-fiber distance of 5 to 100 μm as a non-woven fabric is characterized by containing an aqueous detergent composition. And a skin cleaning sheet.

In this case, the nonwoven fabric has a diffusibility such that the spread when dropping 100 μL of the aqueous detergent composition becomes 1 cm ² or more, and the initial gradient after 2 seconds of 50% compression load is 100 g. It is more preferable to use one having a flexibility of not more than / s.

Hereinafter, the present invention will be described in more detail. The nonwoven fabric constituting the skin cleaning sheet of the present invention is a hydroentangled nonwoven fabric made of cellulose fibers and synthetic fibers.

As the cellulose fibers constituting the nonwoven fabric, various cellulosic fibers can be used, for example, natural cellulose fibers such as cotton, pulp and hemp, and regenerated cellulose fibers such as rayon fiber, tencel fiber and cupra. And one or more of these can be used. In the present invention, among these cellulosic fibers, cotton, rayon fiber, pulp or Tencel fiber is more preferably used from the viewpoint of improving the feel of the nonwoven fabric.

Although the average fineness of the cellulose fiber is not particularly limited, it is preferably 3 d (denier) or less, particularly 2 d or less, and more preferably 1.5 d or less, from the viewpoint of improving the feel to the skin and improving the absorbability of makeup stains. .

As the synthetic fiber, various synthetic fibers can be used. For example, a fiber made of a polyolefin resin such as polypropylene or polyethylene, a fiber made of a polyamide resin such as polyester, polyacryl or nylon, or a fiber made of a polyamide resin such as nylon. And fibers made of copolymers and denatured products of these resins. These may be combined.
Among these synthetic fibers, fibers composed of polyolefin-based, polyester-based, and polyamide-based resins in terms of improving the feel of the nonwoven fabric, improving the absorbability of makeup stains, and producing composite synthetic fibers such as splittable composite fibers. It is preferable to use fibers made of a copolymer or modified product of these resins. Furthermore, among the synthetic fibers, from the viewpoint of improving the feel of the nonwoven fabric and improving the absorption of makeup stains,
It is more preferable to use splittable conjugate fibers.

Examples of splittable conjugate fibers include combinations of polyethylene terephthalate / polyethylene, polyethylene terephthalate / nylon, polyethylene terephthalate / polypropylene, polypropylene / ethylene-vinyl alcohol copolymer, polypropylene / polyethylene, etc. Specific properties such as the number include those shown in Table 5 in Examples described later. The combination of the splittable conjugate fibers is not particularly limited, but a combination with polyethylene terephthalate / polyethylene is preferable from the viewpoint of improving the feel of the nonwoven fabric and improving the absorbability of makeup stains. In addition, although the fiber sectional view of the conjugate fiber shown in Table 5 was shown in FIG. 1, it is not limited to this and the number of divisions is not particularly limited. However,
The average fineness after division is not particularly limited,
Those having a thickness of 0.5 d or less are preferred from the viewpoint of improving the feel of the nonwoven fabric and improving the absorbability of makeup stains. In any case, even when these splittable conjugate fibers are used, the ratio of the fineness of the cellulose fibers to the fineness of the synthetic fibers may be 2.5 to 12.

The average fineness of the synthetic fiber is not particularly limited, but is not more than 3d (denier), particularly not more than 2d, and more preferably not more than 2d.
5d or less is preferable from the viewpoint of improvement of the touch and improvement of the absorbability of makeup stains.

In the present invention, the synthetic fibers and the cellulose fibers constituting the nonwoven fabric may have a uniform circular cross section, but may have a triangular, star, four-leaf, cloud-like shape or the like. It may have a certain irregular cross section or a composite fiber cross section of a combination of cellulose and synthetic fiber.

In the present invention, even when the fibers having these composite fiber cross sections are used, the ratio of the average fineness of the cellulose fibers to the average fineness of the synthetic fibers is 2.5 to 2.5.
It is necessary to be 12, preferably 3 to 8, and when the fineness ratio is within the above range, the absorbability of makeup stains is good and the skin contact is good. When the fineness ratio between the synthetic fiber and the cellulose fiber is outside the above range, the absorbability of makeup dirt is deteriorated, and not only the makeup removal is deteriorated, but also the skin contact is deteriorated, and during use, the feel after use is poor. And other problems arise. In particular, if the fineness ratio is smaller than the above value, good make-up removability, use feeling, and makeup wiping property cannot be obtained. If the fineness ratio is larger than the above value, good make-up removability, use feeling cannot be obtained, and makeup wiping property is not obtained. It is inferior to.

The above fineness can be defined as follows. About the fineness of the fiber: The thickness of the fiber can be expressed by measuring the width or diameter (there is a microscopic measurement method),
There are few natural fibers and synthetic fibers of the same shape except some fibers. Because it is difficult to be accurate,
In general, it is usually expressed by the ratio of mass to length, and these are called fineness, and denier is used as a unit (tex has recently been introduced as an international unit). Denier indicates the mass of the fiber per 9000 m length in grams (tex is the mass per 10,000 m length in grams) and uses the d or D symbol.

The distribution of the constituent fibers of the nonwoven fabric is not particularly limited, and fibers having different thicknesses, types, properties, etc. may be distributed in layers in the thickness direction, but fibers having different thicknesses, types, properties, etc. Are preferably mixed at random in terms of make-off properties and detergent retention.

The nonwoven fabric used in the skin cleansing sheet of the present invention has a mass ratio of cellulose fibers to synthetic fibers of 80/20 to 10/90, preferably 49/51.
~ 20/80, more preferably 40/60 ~ 20/80
It is essential that the ratio is within the above range, so that the feeling of use is good, the feeling when wiping is good, and the absorbability of makeup stains is also good. When the content of the cellulose fiber is small and the mass ratio is smaller than the above value, the retention of the aqueous detergent is reduced, and when the content of the cellulose fiber is large and the mass ratio is larger than the above value, the skin contact and makeup removal are reduced. Therefore, it is not preferable.

Further, the nonwoven fabric used in the present invention has an average fiber-to-fiber distance of 5 to 100 μm, preferably 10 to 60 μm.
When the thickness is in this range, the skin contact and the absorbability of makeup stains are good, and a high detergency can be exhibited. Even if the average fiber-to-fiber distance is shorter than the above-mentioned value, no further improvement in performance is recognized. If the average fiber-to-fiber length is longer than the above-mentioned value, the skin contact is reduced and the absorbability of makeup stains is undesirably reduced. The average inter-fiber distance can be calculated by the following formula.

[0023]

(Equation 1)

In the present invention, considering the effect that the aqueous detergent impregnated in the nonwoven fabric solubilizes makeup stains and sebum stains and sucks up the nonwoven fabric, the diffusibility of the aqueous detergent composition in the nonwoven fabric is described below. The spread area when 100 μL of the aqueous cleaning composition according to the present invention is dropped on the nonwoven fabric is preferably 1 cm ² or more, more preferably 2 cm ² or more. Therefore, it is preferable to select and use a nonwoven fabric whose diffusivity is within the above range. If the diffusivity is lower than the above value, the detergency against makeup stains and sebum stains may decrease. In addition, this diffusivity test was conducted using an aqueous detergent 10 to which a dye was added.
0 μL is dropped on the nonwoven fabric, and the elliptical stain after one minute can be obtained by measuring the major axis and the minor axis to calculate the area.

In order to reduce the load on the skin when wiping makeup, the nonwoven fabric should be as soft as possible against the skin. Therefore, the flexibility of the nonwoven fabric measured as described below is 100 g / s or less, particularly 70 g / s or less, especially 50 g / s or less are preferred. This flexibility
Texture Analyzer (TA-XT, manufactured by SMS)
It can be measured by obtaining the initial gradient 2 seconds after the application of a compression load (set to compress the nonwoven fabric by 50%) under the following conditions in 2). Flexibility measurement conditions Compressive load: 50% (set to compress the nonwoven fabric by 50%) Probe: 2 cm in diameter Falling speed: 0.1 mm / s Other: Set to measure from the time when the initial load is detected as 5 g

As a method for producing a nonwoven fabric having such properties used in the present invention, a hydroentanglement method is employed from the viewpoint of good skin feel and the like. In addition, as a manufacturing method, there are a chemical bond method in which the web is bonded with an adhesive and a thermal bond method in which heat is applied to the web to self-adhere the fibers or bond them with an adhesive fiber. To adhere
The degree of freedom of the fiber is reduced, and it becomes a strong non-woven fabric.
As a result, the skin contact becomes poor, which is not preferable.

In the present invention, the aqueous detergent composition to be contained in the nonwoven fabric is not particularly limited, and various ones can be used as long as they are used for skin cleansing. Those having a nonionic surfactant having an HLB value of 10 to 15, a liquid oil component, a polyhydric alcohol and / or a glycol ether as main components are preferable.

In this case, the nonionic surfactant may be any one which is used in a usual detergent composition, but as described above, the average HLB value is 10 to 15, particularly 1
Those having 2 to 14 are preferable, and for example, polyoxyethylene fatty acid ester, polyoxyalkylene alkyl ether, polyoxyethylene glycerin fatty acid ester, fatty acid polyglyceryl ester, and fatty acid alkylolamide are preferable. Among them, polyoxyethylene glycerin fatty acid ester is more preferable because it does not have stickiness after use. In particular, the addition mole number of ethylene oxide is 5 to 5.
15, preferably 7 to 10, wherein the fatty acid moiety has 8 carbon atoms.
Those containing 16, preferably 12 carbon atoms in an amount of 30% or more of the total fatty acid portion may have a high makeup removing effect. For example, polyoxyethylene monolaurate (7)
Glycerin (HLB12), polyoxyethylene monolaurate (10) glycerin (HLB14), mono-hardened coconut oil fatty acid polyoxyethylene (7) glycerin (H
LB12), mono-hardened coconut oil fatty acid polyoxyethylene (10) glycerin (HLB14), monococonut oil fatty acid polyoxyethylene (7) glycerin (HLB12) and the like are preferably used. As the liquid oil, those generally used as a cosmetic base can be employed. Examples thereof include hydrocarbons such as paraffin, wax, petrolatum, and squalane, fatty acid glycerides, higher fatty acids, higher alcohols, higher alcohol esters, higher alcohol ethers, fatty acid esters, natural animal and vegetable oils, and silicones. Especially from the point of detergency and feeling of use, squalane, jojoba oil, sunflower oil, olive oil, tsubaki oil, grape oil,
Preferred are glyceryl tri-2-ethylhexanoate, 2-ethylhexyl 2-ethylhexanoate, cetyl 2-ethylhexanoate, and glyceryl tricapryl / caprate.

Examples of the polyhydric alcohol include hexylene glycol, ethylene glycol, propylene glycol, isopropylene glycol, dipropylene glycol, 1,3-butylene glycol, diethylene glycol, glycerin, pentaerythritol, sorbitol and the like. Of these, propylene glycol, glycerin, 1,3-butylene glycol,
Sorbitol and dipropylene glycol are preferred from the viewpoint of use feeling. Further, as the glycol ether, for example, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether,
Examples thereof include diethylene glycol monoethyl ether, diethylene glycol monopropyl ether, diethylene glycol monobutyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, and ethylene glycol monophenyl ether. Among these, diethylene glycol monoethyl ether is particularly preferred from the viewpoint of feeling of use.

The nonionic surfactant, liquid oil, polyhydric alcohol and / or glycol ether can be used alone or in combination of two or more.

In this case, the compounding amount of the nonionic surfactant can be 2 to 15% (mass%, the same applies hereinafter), particularly 3 to 12%, and the polyhydric alcohol and / or glycol ether is 0%. 0.1 to 10%, particularly 0.5 to 8%, and the liquid oil content can be 0.01 to 5%, particularly 0.05 to 0.9%. In this case, the aqueous detergent composition The product contains 0.01 to 5 parts by mass, preferably 0.03 to 2 parts by mass of a nonionic surfactant with respect to 1 part by mass of the nonwoven fabric.
Polyhydric alcohol and / or glycol ether
It is preferable to mix 1 to 3 parts by mass, preferably 0.002 to 2 parts by mass, and 0.001 to 5 parts by mass, preferably 0.002 to 2 parts by mass of an oil component from the viewpoints of detergency and feeling in use.

The above-mentioned detergent composition may contain 3 to 15% of ethanol in order to give a refreshing feeling of use, as well as a humectant, a bactericide, a chelating agent, a pigment, a fragrance,
An antioxidant, a pH adjuster, an anti-inflammatory agent and the like can be added.

Considering that the nonwoven fabric is impregnated with the detergent composition, the viscosity of the detergent composition at 20 ° C. is 5,000 mPa · s or less, preferably 3,000 mPa · s.
It is preferably at most a · s, more preferably at most 2,000 mPa · s. If the viscosity is out of the above range, the nonwoven fabric is less likely to be impregnated with the aqueous cleaning agent, which may be undesirable in performance.

As a means for incorporating the aqueous detergent composition into the nonwoven fabric, a method of impregnating the nonwoven fabric with the aqueous detergent composition is preferably employed. Specifically, a method in which the nonwoven fabric is folded and impregnated by a spray method is exemplified.

In this case, the content of the aqueous detergent composition is as follows:
The amount is preferably 1.5 to 5 times, more preferably 2.5 to 4 times the mass of the nonwoven fabric. If the content is too small, sufficient detergency may not be obtained. In some cases, no improvement in power is observed.

The cleaning sheet of the present invention is used for skin.
In particular, it can be suitably used as a face washing sheet, and is useful for removing make-up and sebum stains, for example, by incorporating a make-up cleansing composition as a cleansing composition. It should be noted that a general method can be used for the method, and a dirt on the skin surface may be wiped off by a normal method.

[0004] In addition, there is also a method of wiping with a tissue paper or the like using a low viscosity liquid for removing makeup,
In this case, the dirt cannot be efficiently adsorbed on the tissue paper, and both sides of the tissue paper are immediately stained due to the back-inside. Furthermore, the cleaning power for sebum dirt including solid dirt clogged with pores is not sufficient, and it is preferable to rub the skin strongly with tissue paper in order to make the cleaning power sufficient, since it damages the skin. However, there was a problem that a satisfactory cleaning power could not be obtained.

[0006] In particular, Japanese Patent Application Laid-Open No. 11-21121 discloses that
A sheet for washing skin containing a nonwoven fabric having a HLB of 10 to 16, a polyhydric alcohol or a glycol ether, and water on a sheet (a nonwoven fabric made of a natural fiber having an average weight of about 20 to 120 g / m ² ); -49641 discloses a hydroentangled nonwoven fabric having a cellulose content of 50% by weight or more, an average weight of 20 to 120 g / m ² , an average fineness of constituent fibers of 3d (denier or less), and a dry reflectance of 45% or more. In addition, a nonionic surfactant (HLB10-1
6), a skin-cleaning sheet containing water has been proposed, which has high detergency, low irritation, makes it difficult for dirt to pass through, and has a good feel upon use. However, these skin cleaning sheets have a problem that it is difficult to say that the effect of removing makeup is sufficiently satisfactory, and that the sheet has poor contact with the skin, and there is a concern that the skin may be damaged when removing makeup. Therefore, development of a higher quality skin washing sheet in which the above-mentioned problems have been improved is desired.
