Description

[Technical Field]

[0001] The present invention relates to a dry sheet for wiping water off the skin after bathing or washing hands and fingers, and a method for manufacturing the same, and more particularly to a dry sheet that can wipe water off the skin and impart beauty ingredients to the skin, and a method for manufacturing the same. [Background technology]

[0002] Towels have traditionally been used to wipe away water from the skin after bathing, etc. However, these towels are used solely for wiping away water from the skin, and are not used to deliver beauty ingredients to the skin. Therefore, to deliver the beauty ingredients, a liquid containing the beauty ingredients must be separately applied to the skin after wiping away the water, which is troublesome.

[0003] Meanwhile, a body cleansing sheet has been proposed that can wipe away sweat and sebum from the skin and also provide a refreshing feeling to the skin (Patent Document 1, paragraph 0005). This body cleansing sheet has powder carried between the constituent fibers of a nonwoven fabric, and provides a dry feeling to the skin, but does not provide any beauty ingredients to prevent rough skin, etc.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2005-95494 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a dry sheet that can wipe away water from the skin after bathing and can also impart beauty ingredients to the skin. [Means for solving the problem]

[0006] The present invention solves the above-mentioned problems by incorporating a specific compound into a specific nonwoven fabric. That is, the present invention involves incorporating a nonionic surfactant that is solid at room temperature and has a boiling point exceeding 100°C into a nonwoven fabric whose main constituent fiber is cellulosic fiber. is 0.3 to 1.0 g / m 2 , glycerin is 7 to 20 g / m 2 And dihydric alcohols that are liquid at room temperature and have a boiling point above 100°C 10~30g / m 2 The present invention relates to a dry body wipe sheet containing a water-soluble polymer and substantially free of water, and a method for producing the same.

[0007] The nonwoven fabric used in the present invention is primarily composed of cellulosic fibers. Examples of cellulosic fibers include cotton, rayon, and pulp fibers. Cellulosic fibers have excellent water absorption properties and are therefore suitable for wiping away water. From this perspective, the nonwoven fabric contains at least 50% by mass of cellulosic fibers. Fibers other than cellulosic fibers may also contain less than 50% by mass of polyester fibers, polyolefin fibers, and polyamide fibers. In the present invention, it is preferable to use a nonwoven fabric composed of at least 100% cellulosic fibers. Examples of nonwoven fabrics that can be used include nonwoven fabrics in which the constituent fibers are entangled with each other, nonwoven fabrics in which the constituent fibers are self-fused with each other, nonwoven fabrics in which the constituent fibers are bonded with thermally adhesive fibers, and nonwoven fabrics in which the constituent fibers are bonded with a binder. Among these, nonwoven fabrics that do not use thermally adhesive fibers or binders are preferred. If the nonwoven fabric contains materials other than cellulosic fibers, such as thermal adhesive fibers or binders, the water absorption properties tend to decrease and the fabric may become rough on the skin.

[0008] A particularly preferred nonwoven fabric is a three-layer nonwoven fabric formed by laminating a cotton fiber web, a pulp fiber web, and another cotton fiber web in this order. This three-layer nonwoven fabric is obtained by laminating a pulp fiber web, which is formed by accumulating pulp fibers, on a cotton fiber web, which is formed by spreading and accumulating cotton fibers, and then laminating a cotton fiber web, which is formed by spreading and accumulating cotton fibers, on the pulp fiber web, and then spraying a water stream to entangle the constituent fibers. This three-layer nonwoven fabric has a pleasant feel against the skin because the front and back surfaces are mainly composed of cotton fibers, and has excellent water absorbency because the interior is mainly composed of pulp fibers. The mass of the nonwoven fabric is 30 to 100 g / m 2 It is preferable that the degree of

[0009] In a nonwoven fabric, at least the following compounds are supported on the surface of the constituent fibers or between the constituent fibers: a nonionic surfactant that is solid at room temperature and has a boiling point exceeding 100°C, glycerin, and a dihydric alcohol that is liquid at room temperature and has a boiling point exceeding 100°C. Here, room temperature refers to 15°C. Examples of nonionic surfactants that are solid at room temperature and have a boiling point exceeding 100°C include polyglycerin fatty acid esters, glycerin fatty acid esters, polyoxyethylene polyhydric alcohol fatty acid esters, polyoxyethylene fatty acid esters, and polyoxyethylene alkyl ethers. In the present invention, polyglycerin fatty acid esters are preferably used, and polyglyceryl-10 myristate, which is particularly less irritating to the skin, is most preferably used. The reason for using a nonionic surfactant that is solid at room temperature is to emulsify glycerin or a dihydric alcohol, which are liquid at room temperature, and support the emulsified surfactant on the surface of the constituent fibers or between the constituent fibers in a smooth state. The reason for using a nonionic surfactant with a boiling point exceeding 100°C is to prevent the nonionic surfactant from evaporating from the nonwoven fabric during the production of the dry sheet.

[0010] Glycerin is a cosmetic ingredient that is liquid at room temperature and provides moisturizing properties to the skin. Dihydric alcohols that are liquid at room temperature and have a boiling point above 100°C also provide moisturizing properties to the skin. Examples of such dihydric alcohols include propanediol and pentylene glycol. Propanediol works in conjunction with glycerin to provide moisturizing properties to the skin. Pentylene glycol also has an antiseptic effect.

[0011] The water-removing dry wipe sheet of the present invention may contain other cosmetic ingredients in addition to glycerin and dihydric alcohol. For example, it may contain other cosmetic ingredients such as an anti-inflammatory agent such as dipotassium glycyrrhizinate or an anti-aging agent such as Symfinity 1298 manufactured by Symrise. It may also contain fragrances, thickeners, cosmetic ingredients, etc. Compounds extracted from plants such as lavender or compounds extracted from animals are used as fragrances. Polysaccharides such as xanthan gum are used as thickeners.

[0012] The content of nonionic surfactants in the wet wipe dry sheet that are solid at room temperature and have a boiling point exceeding 100°C is 0.3 to 1.0 g / m 2 The glycerin content is 7 to 20 g / m 2 The content of dihydric alcohols that are liquid at room temperature and have a boiling point of over 100°C is 10 to 30 g / m 2 When the content of each compound is at this level, the wet wipe dry sheet will feel smooth to the touch even if it contains compounds that are liquid at room temperature. When other beauty ingredients are also contained, the content of these ingredients should be 0.05 to 0.20 g / m 2 That's about it.

[0013] The water-wiping dry sheet according to the present invention is substantially free of water. By "substantially free of water," we mean that it may contain water that is inherently adsorbed within the cellulosic fibers. Specifically, it means that it may contain water at a level equivalent to the official moisture regain contained within cotton fibers or pulp fibers. Furthermore, because it is substantially free of water, bacteria, mold, and the like are less likely to grow, even without the addition of preservatives such as parabens or phenoxyethanol.

[0014] The water-wiping dry sheet according to the present invention can be produced, for example, by the following method: impregnating a nonwoven fabric mainly composed of cellulosic fibers with an aqueous solution obtained by dissolving in water a nonionic surfactant that is solid at room temperature and has a boiling point exceeding 100°C, glycerin, and a dihydric alcohol that is liquid at room temperature and has a boiling point exceeding 100°C, and then blowing hot air at a temperature of 90°C or higher and lower than 100°C onto the fabric to evaporate the water in the aqueous solution.

[0015] The method for impregnating the nonwoven fabric with the aqueous solution can involve immersing the nonwoven fabric in the aqueous solution and then squeezing the solution. Other methods include applying the aqueous solution to the nonwoven fabric using a kiss coater or spraying the aqueous solution onto the nonwoven fabric. The amount of aqueous solution impregnated into the nonwoven fabric is approximately 1 to 5 times the mass of the nonwoven fabric. To dry and remove the water in the aqueous solution, it is preferable to blow hot air at a temperature of 90°C or higher but less than 100°C onto the nonwoven fabric. The reason for using hot air at a temperature of 90°C or higher but less than 100°C is to prevent the evaporation of compounds with a boiling point of 100°C or higher. Specifically, this is to prevent the evaporation of nonionic surfactants, glycerin, and dihydric alcohols. The reason for blowing hot air is to penetrate the nonwoven fabric and evaporate the water retained between the constituent fibers of the nonwoven fabric by capillary action, thereby drying and removing the water.

[0016] The water-wiping dry sheet according to the present invention can be used as a bath towel after a bath, as a hand towel after washing your hands, or as other towels, handkerchiefs, tissues, etc. [Effects of the Invention]

[0017] When water is wiped off the skin with the dry wipe sheet according to the present invention, the nonwoven fabric, whose main constituent fibers are cellulose-based fibers, absorbs the water. The nonionic surfactant then mixes the glycerin and dihydric alcohol with the water on the skin, delivering the glycerin and dihydric alcohol to the skin. Therefore, using the dry wipe sheet according to the present invention not only effectively wipes water off the skin, but also delivers beauty ingredients such as glycerin to the skin. If the dry sheet contains other beauty ingredients, the other beauty ingredients can also be delivered to the skin. This eliminates the need for the double step of wiping off water from the skin and then delivering the beauty ingredients, achieving the effect of simultaneously wiping off water from the skin and delivering the beauty ingredients to the skin in a single step.
