Abstract: The problem addressed by the present invention is to provide a nonwoven fabric for a skincare product having excellent handling properties for skincare products and further having superior adherence to the skin and wiping properties for cosmetics adhering to the skin for skincare products. The nonwoven fabric for a skincare product includes thermoplastic resin fiber with a single fiber diameter of 50 - 800 nm and cellulose fiber with a tensile strength of 1.9 cN/dtex or less as measured according to JISL 1015: 2010 8.7.2 and is characterized in that the proportion of thermoplastic resin fiber and cellulose fiber content to the total mass of the nonwoven fabric for a skincare product is 85% by mass or greater, and the mass ratio (thermoplastic resin fiber/cellulose fiber) of content of the thermoplastic resin fiber and the cellulose fiber is 0.06 - 0.22.
WE CLAIM:
1. A nonwoven fabric for skin care products, the nonwoven
fabric comprising:
a thermoplastic resin fiber having a single fiber diameter of 50 nm or more and 800 nm or less; and
a cellulose fiber having a tensile strength measured in accordance with JIS L 1015:2010 8.7.2 of 1.9 cN/dtex or less, wherein
a total content of the thermoplastic resin fiber and the cellulose fiber is 85% by mass or more relative to a total mass of the nonwoven fabric for skin care products, and
a content ratio by mass of the thermoplastic resin fiber and the cellulose fiber (Thermoplastic resin fiber/Cellulose fiber) is 0.06 to 0.22.
2. The nonwoven fabric for skin care products according to claim 1, wherein the thermoplastic resin fiber is a polyamide fiber.
3. The nonwoven fabric for skin care products according to claim 1 or 2, wherein the cellulose fiber is rayon.
4. The nonwoven fabric for skin care products according to any one of claims 1 to 3, wherein a fiber length of the cellulose fiber is 35 mm or more.
5. A face mask comprising the nonwoven fabric for skin care products according to any one of claims 1 to 4.
6. A cleansing sheet comprising the nonwoven fabric for skin care products according to any one of claims 1 to 4.
