Problems solved by technology

[0005] The problem with the above-mentioned dry sheets containing oil-based absorbents is that they cannot remove water-based dirt such as sweat and salt and water-soluble proteins contained therein
On the other hand, a problem with the aforementioned wet sheets comprising aqueous cleansing solutions is that they do not effectively remove oily soils and thus do not adequately prevent shine or smudging

preparation example Construction

[0043] For example, nonwovens made of natural fibers or synthetic fibers can be used as the liquid storage layer. Examples of non-woven fabrics include: wet or dry pulp layers, or fibers such as rayon, acetate, acrylic, polyester, polyethylene, polypropylene, polyurethane, polyamide, cotton, pulp, or these fibers A non-woven fabric made of a mixture of two or more fibers or a composite material. Specific examples include cellulose nonwoven fabrics containing polyolefin short fibers, and hybrid nonwoven fabrics containing cellulose and acrylic compounds or nylon containing polyolefin short fibers. Examples of methods for producing such nonwoven fabrics include hydroentangling, hydroentangling, air-laid web methods, and thermal bonding methods. Among them, wet entanglement and dry entanglement methods are particularly preferred in view of the softness and density of the resulting nonwoven fabric.

Embodiment 1

[0071] A porous polypropylene melt-blown nonwoven fabric having a thickness of 260 μm (Syntex MB; an 80 μm thick nonwoven fabric produced by calendering V3030N1 (manufactured by Mitsui Chemical); pale pink) was spread on a sheet having a basis weight of 40 g / m 2 Cotton non-woven fabric (Cottoace C040S / A01, manufactured by Unitika, undyed) was coated with a heat-sealing agent on one side of the porous melt-blown non-woven fabric, and the two layers were melt-bonded in a quilted pattern (stitch pattern) together. The resulting laminate was cut into a size of 10 cm x 5 cm, and the aqueous lotion shown in Table 1 below was sprayed on the cotton non-woven fabric until the absorbency reached the percentage shown in Table 3. From this we get figure 1 Double-sided laminated personal cleansing tablet shown.

Embodiment 2 and 3

[0073] Prepared in the same manner as in Example 1 Figure 5 The single-sided side-by-side personal cleansing sheet shown (Example 2), and Figure 6 Tessellated personal cleansing sheet shown (Example 3).

Abstract

A personal cleansing sheet with which the skin and hair can be easily cleansed of oily soils such as sebum and aqueous soils such as sweat or salts, has a structure in which an oily substance absorption layer that serves as a region that absorbs oil substances is laminated with an aqueous cleansing liquid retention layer that serves as a region that retains an aqueous cleansing liquid.

Description

technical field [0001] The present invention relates to personal cleansing tablets which readily remove greasy soils, such as sebum, or aqueous soils, such as sweat or salt, from the skin or hair. In particular, the present invention relates to personal cleansing sheets that easily cleanse the skin and hair without staining cosmetic products such as foundation. Background technique [0002] In recent years, skin cleansing sheets for removing adhering dirt from hair and skin (particularly the face) have been commercially available. These skin cleansing tablets are mainly divided into two categories: dry sheets containing oil-based absorbents, which are mainly used to remove oily dirt such as sebum; wet sheets containing aqueous cleansing liquids, which are mainly used to remove water-based dirt such as sweat or salt. [0003] Typical examples of dry sheets containing oil-based absorbents include fibrous raw materials such as natural pulp, paper mulberry, mitsumata, hemp, whi...
