Specification

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.
