The applicator head is an integral injection molded part made of a thermoplastic elastomer material. During production, the applicator head is integrally formed by an injection mold using a thermoplastic elastomer material, and then a flocking layer 21 is formed on the surface of the applicator portion 20 of the applicator head through a flocking process. When in use, the applicator head is assembled to the brush rod through the mounting portion 10, and the applicator portion 20 uses the flocking layer 21 to dip the cosmetic material and apply it to the user's makeup area to complete the makeup operation.

[0032] Among them, the fineness of the fluff is 2.4D to 3.6D. D stands for denier, which is a fixed-length density unit for fine-bundled silk, rayon, and nylon textile fibers. It refers to the mass of 9000m of fiber at the standard moisture regain, and the unit is denier. Denier is a unit of measurement for fiber fineness. 9000m of fiber weighs 600 grams, and the fiber is called 600D fiber. 9000m of yarn weighs 600 grams, and the yarn is called 600D yarn. The larger the number, the thicker the yarn or fiber.

[0033] The applicator head in the present application is made of thermoplastic elastomer material, the application portion is designed as a columnar structure, the fineness of the fluff is 2.4D to 3.6D, and the length of the fluff is 1.2mm to 1.8mm. Therefore, when applying makeup, the obtained applicator head can apply the material more evenly and delicately, thereby improving the makeup effect.

[0034] The fineness of the fluff is 2.7D to 3.3D. Optionally, the fineness of the fluff is 2.4D, 2.6D, 2.8D, 3D or 3.2D. Optionally, the fineness of the fluff is 3.0D. The length of the fluff is 1.35mm to 1.65mm. Optionally, the length of the fluff is 1.3mm, 1.5mm, 1.6mm or 1.7mm. Optionally, the length of the fluff is 1.5mm. In one embodiment, the fineness of the fluff is 3.0D and the length is 1.5mm, so that the material applied to the application part is the most uniform, the makeup effect is the best, and the material can be strong.

[0035] The thermoplastic elastomer material includes at least one of polyurethane thermoplastic elastomer material, styrene thermoplastic elastomer material and polyester thermoplastic elastomer material. Optionally, the applicator is made of polyester thermoplastic elastomer TPEE, polyurethane thermoplastic elastomer TPU or styrene thermoplastic elastomer TPES.

[0036] The applicator head is an integral injection molded part made of polyester thermoplastic elastomer material.
