The present invention includes a contact portion in contact with the skin is buried in the makeup powder, a gripping portion that is held by the hand while forming the opposite side to the contact portion, and a side portion connecting the contact portion and the gripping portion, the metal nanoparticles for making antimicrobial Provides a functional puff evenly distributed over the contact portion.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 2 are diagrams for explaining a functional puff according to a first embodiment of the present invention.

Referring to FIG. 1, the functional puff 100 according to the present invention includes a contact part 110 that is contacted with skin by being coated with makeup powder, a grip part 120 that is gripped by a hand while forming a surface opposite to the contact part 110. Including the side portion 140 connecting the contact portion 110 and the gripping portion 120, the metal nanoparticles 130 for providing antimicrobial properties are uniformly distributed in the contact portion 110.

The functional puff 100 is manufactured by foaming a liquid resin. The manufacturing process of the functional puff 100 is as follows. When the liquid resin is poured into the foamer together with the predetermined metal nanoparticles 130 and the usual additives and foamed, the resin is made of a sponge material having a plurality of micropores. When the resin of the sponge material is injected into the mold, the functional puff 100 having a circular or rectangular shape is made. As the conventional additive, a curing agent or a vulcanizing agent may be used, and a blowing agent may be added according to the foaming method.

The contact part 110 is a part where the cosmetic powder is buried in contact with the skin, and the cosmetic powder is buried in the micropores in the contact part 110, and it is applied thinly on the skin as it comes into contact with the skin. However, the cosmetic powder still remains in the micropores of the contact unit 110, and may be deteriorated when it comes into contact with air. Therefore, since the metal nanoparticles 130 having antimicrobial properties are uniformly distributed on the contact portion 110, it is possible to prevent deterioration of the cosmetic powder and to prevent bacterial habitat. The contact part 110 includes at least one of Nitrile Butadiene Rubber (NBR), SBR (Styrene Butadiene Rubber, SBR), NR (Natural Rubber, NR), or PVA (Polyvinyl Alcohol, PVA). It can be prepared by foam molding a liquid resin.

The gripping portion 120 is a portion to be gripped by hand, and usually forms a body with the contact portion 110. Since a considerable amount of metal nanoparticles 130 are also distributed in the gripping portion 120, a cosmetic powder may be buried in the gripping portion 120 in some cases and used as the contact portion 110.

The side portion 140 is a portion connecting the contact portion 110 and the gripping portion 120, the functional puff 100 is made of a foam molded resin with a cushion feeling to have a predetermined height accordingly The side portion 140 is to be formed.

The metal nanoparticles 130 are added together when foaming the liquid resin, and are evenly distributed throughout the functional puff 100 including the contact portion 110. The more metal nanoparticles 130 are present in the contact portion 110, the better the antibacterial action can be exerted, in order to exhibit the antimicrobial action of 95.0% or more, the metal nanoparticles 130 with respect to the total weight It is preferred to mix at 0.5 to 10% by weight. If the metal nanoparticles 130 is 10% by weight or more, not only the moldability of the product may be lowered, but may be detached from the puff, and when the metal nanoparticles 130 are 0.5% by weight or less, the antimicrobial effect is reduced. The metal nanoparticles 130 may include gold (Au), silver (Ag), platinum (Pt), palladium (Pd), ruthenium (Ru), iron (Fe), copper (Cu), cobalt (Co), or nickel ( Metal nanoparticles containing at least one of Ni) can be used.

Referring to FIG. 2, silicon oxide (SiO ₂ ) 131 is coated on the surface of the metal nanoparticle 130. The silicon oxide 131 is a deodorizing action and anion and far infrared rays are generated, the coating thickness is preferably 10 nm or less. In the case of coating 10 nm or more, the deodorizing action by the silicon oxide 131 and the effect of generating anions and far infrared rays are increased, but the antibacterial effect of the metal nanoparticles 130 is reduced. The coating may include not only silicon oxide (SiO ₂ ) 131, but also at least one of titanium oxide (TiO ₂ ) or aluminum oxide (Al ₂ O ₃ ).

In the conventional method of manufacturing the metal nanoparticles 130, a gas phase method synthesized using a high voltage in a vacuum state and a liquid phase method manufactured using an organic solvent and a polymer or a block copolymer. ). Among the liquid phase methods (Liquid Phase Method), there are precipitation, coprecipitation, impregnation and sol-gel process by neutralization titration. However, the above-mentioned conventional manufacturing method cannot obtain the metal nanoparticles 130 coated with the silicon oxide 131 of 10 nm or less. Therefore, the method for obtaining the metal nanoparticles 130 coated with the silicon oxide 131 of 10 nm or less is as follows.

First, the metal is dissolved in acid to form metal ions. It can be made by dissolving in a solution selected from the group consisting of aqua regia (a mixture of three volumes of hydrochloric acid and one volume of nitric acid), nitric acid, hydrochloric acid and sulfuric acid to form metal ions. Metals get metal ions by dissolving in nitric acid, hydrochloric acid and sulfuric acid.

Next, a solvent and an additive are mixed with the metal ion. By mixing a solvent and an additive with a metal ion, the particle diameter of a metal ion can be controlled in the state below 10 nm. The solvent is preferably used by mixing alcohol, glycol solvent and water. The additive is preferably selected from the group consisting of ammonia water, β-Alanine and triethanolamine, and these additives form metal complex ions, thereby preventing instantaneous growth of particles due to rapid reduction of metal ions.

Next, a silicone compound such as TEOS (tetraethylorthosilicate) or a derivative thereof is added and hydrolyzed while adjusting the temperature, pH, and conditions of the added solvent or additive during hydrolysis. At this time, the pH during hydrolysis is adjusted to pH 4 to pH 14, the temperature is adjusted to -70 ℃ to 100 ℃.

Finally, a reducing agent is added to reduce the metal compound. The reducing agent is a hydrazine mono hydrate (H ₂ NNH ₂ · ₂ O); Compounds containing hydrazine monohydrate _{(H 2 NNH 2 · 2 O} ); And R is an alkyl or alkoxy group having 1 to 20 carbon atoms, and n is an organic alkaline material having a structure of R-NH _n having 0 to 3 integers. Preferably hydrazine mono hydrate (H ₂ NNH ₂ · ₂ O) or a mixture of alkylamine and alkoxyamine is used. In the metal reduction of a metal compound, the particle diameter or shape of the metal can be controlled by controlling the reduction rate by selecting a solvent, pH, temperature, and the like. The temperature is usually adjusted at -70 ° C to 100 ° C, more preferably -50 ° C to 0 ° C. This is because reduction does not occur well when the temperature is less than -50 ° C, and when the temperature exceeds 0 ° C, the reduction rate is rapidly increased, making it difficult to obtain metal nanoparticles 130 having a desired size. The pH is usually adjusted to pH 4 to pH 14, more preferably pH 4 to pH 7. This is because the reduction does not occur when the pH is less than 4, and the reduction rate is faster when the pH is exceeded.

In some cases, the metal nanoparticles 130 may be sprayed on not only the contact portion 110 but also the gripper 120 to enhance antimicrobial activity. The amount of the metal nanoparticles 130 is preferably about 0.5 to 10% by weight based on the total weight. When the amount of the metal nanoparticles 130 is less than 0.5% by weight, the antimicrobial effect may be lowered. When the amount of the metal nanoparticles 130 is more than 10% by weight, the metal nanoparticles 130 may be detached. The metal nanoparticles 130 may include gold (Au), silver (Ag), platinum (Pt), palladium (Pd), ruthenium (Ru), iron (Fe), copper (Cu), cobalt (Co), or nickel ( Ni) may include at least one or more.
