Typically, Puff will be used as a make-up tool to evenly apply cosmetics such as brushes and compacts to the face when making up. Such puffs (puffs) are formed of puffs or synthetic resin materials having a circular shape, a square shape, an elliptical shape, etc., and a fabric is polymerized, When the powder is rubbed on the surface of the cosmetic powder with cushion, fine powder is filled in the pores of the inside and the surface. If the powder in the pore is rubbed while tapping on the desired area, the cosmetic is applied to the skin do.

However, when the liquid cosmetic is applied to such a puff, it is absorbed and impregnated by a sponge positioned inside through the puff made of a material capable of absorbing water or cosmetics.

When the liquid cosmetic material is over-applied, only a part of the absorbed liquid cosmetic material is applied to the skin, and a considerable amount of cosmetic material remains in the sponge, or when the amount thereof is excessive, the cosmetic material is eluted to the surface to which the handle strap is attached.

Therefore, the cosmetics remaining on the sponge are hardened when stored in the puff, so that the soft touch will be lowered in subsequent use. Therefore, the used puff should be washed and used, but the washing water will remain on the sponge again, There is a problem in that bacteria are propagated by residual washing water and cosmetic materials and cause skin troubles.

According to the present invention, the vegetable raw material has an environment-friendly effect by increasing the VOC emission amount and the bio-mass content (%) of the vegetable component. Preferably, the vegetable raw material is a radioisotope mass spectrometry ASTM D-6866 The extract is characterized by having at least one selected from the group consisting of soybean oil, pimazole, camellia extract, and sunflower extract having a BIO-MASS content (%) of 0 to 10 as measured by an analytical method. If the amount is less than 5 parts by weight, the effect of VOC reduction is not significantly reduced, but it is less than the environmentally friendly target level (Bio-Mass,%). If the amount exceeds 15 parts by weight, There is a problem that it is difficult to obtain a desired processed product because the molding operation time of the foam molding phase is prolonged.

According to the present invention, the cross-linking agent may be 1,4-butanediol, tri-methyol propane (TMP), diethanolamine (DEOA / manufacturer: And triethanol amine (TEOA / manufactured by Samil Chemical Co., Ltd.). If the amount is less than 3 parts by weight, the reactivity of the foam crosslinked phase due to the addition of the vegetable raw material is deteriorated There is a problem that it is difficult to obtain a desired initial physical property value. When the amount exceeds 5 parts by weight, the crosslinking of the foam becomes too high, and the foam properties are not so flexible.

According to the present invention, the interfacial stabilizer is a silicone surfactant composed of a siloxane copolymer and having a polydimethylsiloxane and a polyoxyalkylene chain, an anion such as a fatty acid salt, a sulfuric acid ester salt, a phosphoric acid ester salt, B-8002 (manufactured by Evonik), a surfactant L-580 (manufactured by Momentive), L-532 (manufacturer: Momentive), DC- B-8301 (manufacturer: Evonik). If the amount is less than 1 part by weight, the shape of the cell is greatly disturbed during the urethane crosslinking reaction, And if it exceeds 5.00 parts by weight, the cell membrane will be excessively generated so that the air circulation to the outside can not be performed well. As a result, the heat generation of the urethane foam Since there is a disadvantage in that shrinkage upon cooling.

According to the present invention, the antioxidant is selected from the group consisting of SW-1010, SW-1076, SW-1680, Irganox 245, Irganox 1010, Irganox 1076, Igafos 168, Igafos 168, Tinuvin-77DF, Irganox 1010, Igafos 168, TNP and TNPP. If the amount is less than 1.5 parts by weight There is a problem that the color of the outer appearance is yellowed due to the weak exposure to the temperature during the thermoforming process of the foam, and when it exceeds 3.5 parts by weight, the foam property is not smooth and the surface may become hard.

According to the present invention, the amine catalyst is selected from the group consisting of NIAX A-1, NIAX A3LV, NIAX A-230, ZF-10, ZF-22, TEDA and DMEA (Dimethyl ethanolamine) in tertiary amines If the amount is less than 0.05 part by weight, the reactivity of the foam is excessively lowered, and the continuous crosslinkability of the foam in the standard is difficult to reach a desired level. When the amount is more than 0.3 part by weight There is a problem that the reactivity is excessively high and it is difficult to obtain the target standard of the foam, and the VOC emission amount is increased, which may be a harmful cause to the human body.

Herein, the tin catalyst is selected from the group consisting of Stannous octoate, Di-butyl tin laurate (DBTDL), DBTDA (Di-butyl tin acetate), S-26, D-19, T-9 and T- If the amount is less than 0.1 part by weight, it is difficult to satisfy the normal crosslinking property of the foam. Therefore, there is a problem that it is difficult to expect normal urethane reactivity in the specification. When the amount exceeds 0.25 part by weight, urethane crosslinking The wall thickness of the cell during the urethane continuous reaction is excessively increased and the membrane is excessively thickened. Therefore, even if there is a separate film formation (reticulation) due to the resulting membrane (CELL film), the restoration force of the product is remarkably decreased and the air permeability is not greatly improved As a result, there may arise a processing problem that is difficult to infiltrate the liquid material within a desired processing time during the process of injecting the liquid cosmetic material.

According to the present invention, the polyethylene glycol is used to increase the absorbency of the flexible foam obtained by foaming the composition. If the amount of the polyethylene glycol is less than 2 parts by weight, it is difficult to reach the desired level of absorbency, There is a problem that the effect of improvement can not be greatly improved upon injection. When the amount is more than 10 parts by weight, the overall foam properties are not flexible and the excessively rapid reactivity is accelerated due to the increase of the component of low molecular weight.

According to the present invention, the above-mentioned toluene diisocyanate (TDI) is used for obtaining normal behavior during the urethane crosslinking reaction. If the amount is less than 27 parts by weight, it is difficult to obtain desired initial reactivity If the amount is more than 35 parts by weight, the internal exothermic reaction due to the excessive reactivity is accelerated and internal deterioration may occur.

Meanwhile, in the present invention, it is possible to obtain a flexible foam which is increased in working efficiency and immersion / content of the liquid composition when the liquid composition is dipped in accordance with the improvement of the absorption power, by foaming using the above composition.

The flexible foam has a density of 30 to 40 kg / m 3, a hardness of 10 to 50 kgf / 314 cm 2, a rebound resilience of 25 to 45%, a tensile strength of 0.50 to 2.50 kgf / cm 2, an elongation percentage of 50 to 200%, a tear strength of 0.50 to 1.50 kgf it is possible to obtain a flexible foam which satisfies the physical properties of air permeability of 25 to 250 cm3 / cm2 / sec, pore size of 35 to 75 ppi, TVOC of 0.10 to 1.50 ppm, Bio-Mass of 1 to 10% and surface absorption rate of 0.1 to 10 sec .
