Description

Make-up puff containing nano silver particle and nano tourmaline particle and producing method

1 is a manufacturing process of the cosmetic puff according to the present invention.

The present invention relates to a cosmetic puff and a method for producing the same, and more particularly, to a cosmetic puff and a method for producing the same containing silver nanoparticles and tourmaline nanoparticles excellent antibacterial and far-infrared and anion generating effect.

When applying makeup, especially when applying a foundation, the cosmetics are put on a cosmetic puff and applied to the face. When you make up using puffs like this, you will get some cosmetics on the puffs. After makeup, most of these cosmetics will contain the puffs in your cosmetics case. However, the cosmetics in contact with the puff can be easily deteriorated in contact with the air, when the makeup is reused by applying the cosmetic puff, there is a problem that the deteriorated cosmetics on the puff can be applied to the face. In addition, one puff is generally provided in one cosmetic container, and when one puff is used continuously for several months, the puff absorbs sebum and secretions from the skin of the human body and is left for a long time. If you do, mold and bacteria inhabit the puffs, which can cause skin problems.

Therefore, in order to solve this problem, a puff containing an organic antimicrobial agent, an inorganic antimicrobial agent, an organic-inorganic composite antimicrobial agent has been developed. That is, Korean Patent Application No. 2003-69797 discloses a cosmetic puff added with an antibacterial agent such as calcium oxide. However, the results for the antimicrobial effect are not described.

In addition, although efforts have been made to prepare puffs using silver having high antibacterial properties, it is not easy to manufacture puffs capable of maintaining the maximum functionality of silver. That is, it is difficult to maintain a uniform cell and hardness and good powder spreadability during puff production due to trouble with other raw materials during the compounding process. In addition, when the silver is added in the form of a powder, it is difficult to maintain a constant antimicrobial on all products due to the problem of dispersibility.

The technical problem to be achieved by the present invention is to provide a cosmetic puff having excellent antibacterial and functional properties.

The present inventors have earned a lot of research to achieve the technical problem as described above, as a result of the development of a method for producing a cosmetic puff containing nano-sized silver and tourmaline, the cosmetic prepared by using this method The present invention was completed by confirming that the puff has excellent antibacterial and far-infrared emission and anion-releasing function.

In order to achieve the above technical problem, the present invention provides a cosmetic puff comprising a silver nanoparticles and tourmaline nanoparticles in a cosmetic puff mainly composed of latex.

In addition, the present invention comprises a vulcanizing agent, a vulcanization accelerator, a bubble stabilizer and a dispersant, wherein the silver nanoparticles are 0.23 × 10 ^-4 to 0.46 × 10 ^-4 wt% with respect to the latex solids content, tourmaline nanoparticles to the latex solids content Mixing the mixture in an amount of 0.4 × 10 ⁻³ to 0.8 × 10 ⁻³ wt%, followed by stirring to prepare a first mixture; Aging the latex; Adding a first mixture to the aged latex to prepare a second mixture; Adjusting the pH and viscosity of the second mixture; And a coagulant is added to the second mixture of which pH and viscosity are adjusted, and then foaming at 25 to 32 ° C. for 5 minutes to 1 hour.

Hereinafter, the present invention will be described in detail.

In general, silver (Ag) is known to have a function of electromagnetic wave blocking, antibacterial, sterilization, deodorization, and has been used to impart antimicrobial properties to products. However, when the powdered silver is conventionally applied to cosmetic puff products, there is no way to maintain the dispersion and uniform particle size, it is very difficult to apply to the product. In the present invention, as a solution to the conventional problem, it is characterized in that the use of silver nanoparticles (nano silver particles), and adjusted the conditions of each step in the manufacturing process.

That is, in the case of general silver, even if small silver particles are broken down due to the specific gravity problem, dispersibility is a problem. In addition, the ball mill process to make the particles even and small, but there is a problem that the effect of the product is different from the dispersibility of the silver of the upper and lower parts, the shape of the complexed cargo is less effective due to the small content of silver. However, silver nanoparticles have the advantage of solving the problem of dispersibility.

When preparing the cosmetic puff according to the present invention, the content of the silver nanoparticles is preferably 0.23 × 10 ⁻⁴ to 0.46 × 10 ⁻⁴ wt% based on the latex solids content. If the content of silver is less than 0.23 × 10 ^-4 wt%, the antibacterial effect is lowered. If the content of silver is more than 0.46 × 10 ^-4 wt%, the bubble stability of the latex is weakened due to the dispersant content contained in the silver nanoparticles itself, and the pH and viscosity are decreased. There is a problem that the foam is destroyed when foaming, thereby weakening the uniformity of the cell (cell). Therefore, it is preferable to maximize the effect of the silver nanoparticles and to add in the above range so that there is no problem in the foamability of the product.

On the other hand, tourmaline is generally known to generate anions and far-infrared rays, and when added during the manufacture of the cosmetic puff of the present invention, there is an advantage that the functionality of the puff can be improved, in particular, using nano-sized tourmaline desirable. The content of tourmaline nanoparticles is preferably 0.4 × 10 ⁻³ to 0.8 × 10 ⁻³ wt% with respect to the latex solid content of the main component. When the content of tourmaline nanoparticles is less than 0.4 × 10 ⁻³ wt%, the amount of anions generated is less than or equal to the reference value of 500 / cc, If the content exceeds 0.8 × 10 ⁻³ wt%, the content of the dispersant and the moisture increases, resulting in a problem of lowering the viscosity and pH of the compounded latex. Therefore, it is preferable to add in the said range.

To the cosmetic puff according to the present invention, in addition to the silver nanoparticles and tourmaline, any one or more selected from the group consisting of conventional additives, that is, a vulcanizing agent, a vulcanization accelerator, a bubble stabilizer, a coagulant and a dispersant may be further added.

As a vulcanizing agent, a conventional vulcanizing agent containing sulfur (S), selenium (Se) or tellurium (Te) may be used. The vulcanizing agent is based on the latex solid content It is preferable to add 1.7-2.0 wt%.

The vulcanization accelerator may be zinc diethyldithiocarbamate or zinc salt of 2-mercaptobenzothiazole, but is not limited thereto. Can be used. The content of the vulcanization accelerator is preferably added 1.7 to 2.0wt% based on the latex solid content.

The foam stabilizer may include trimembase (ethane, chloro-, polymer with ammonia and formaldehyde), but is not limited thereto, and is preferably added at 0.5 to 0.7wt% based on the latex solid content.

Coagulant may be used but not limited to sodium fluoride, a type commonly used in the art can be used. The amount of coagulant can be adjusted according to the rate of coagulation.

Dispersant may be sodium butylnaphthalene sulfonate (Sodium Butylnaphthalene Sulfonate) may be used, but is not limited thereto, and the type commonly used in the art may be used. The content of the dispersant is preferably added 0.04 ~ 0.06wt% relative to the latex solids content.

The cosmetic puff of the present invention contains a vulcanizing agent, a vulcanization accelerator, a bubble stabilizer, and a dispersant, wherein the silver nanoparticles are 0.23 × 10 ⁻⁴ to 0.46 × 10 ^-4 wt% with respect to the latex solids content, and the tourmaline nanoparticles are latex solids. Mixing the mixture in an amount of 0.4 × 10 ⁻³ to 0.8 × 10 ⁻³ wt% and then stirring to prepare a first mixture; Aging the latex; Adding a first mixture to the aged latex to prepare a second mixture; Adjusting the pH and viscosity of the second mixture; And a coagulant is added to the second mixture of which pH and viscosity are adjusted, followed by foaming at 25 to 32 ° C. for 5 minutes to 1 hour.

The latex is preferably aged for 4 to 8 hours at 25 ~ 32 ℃. When the latex is aged at a temperature and time in the above range, the fine bubbles generated when the latex is added to the compounder can be removed, and the added ingredients can be uniformly dispersed in the latex to adjust pH and viscosity. have. On the other hand, after mixing the components, it is preferable to agitate at a speed of 30 ~ 60rpm, because when the stirring outside the above range, the latex micelle particles are destroyed. Therefore, it is preferable to maintain the stirrer in the above range and to gradually and evenly maintain the constant value.

 On the other hand, when the formulation is added 10wt% or more to the concentration of latex solids during latex foaming during the cosmetic puff manufacturing process, there is a problem in that the stability of the latex is deteriorated due to problems such as viscosity, pH, and the like. In the present invention, this problem is solved by adjusting the viscosity and pH of the whole mixture.

That is, the pH of the second mixture was adjusted to 10.6 to 11 before foaming in the above, and the above problem can be solved by adjusting the pH in this manner. The pH is preferably adjusted to at least one selected from the group consisting of potassium hydroxide and sodium hydroxide, but is not limited thereto. The pH may be adjusted by adding 0.02 to 0.1 wt% based on the latex solid content, in particular 6% potassium hydroxide. Preference is given to using aqueous solutions.

In addition, the viscosity of the second mixture was adjusted to 5,000 to 12,000 cps before foaming in the above, and by adjusting the viscosity in this way, it is also possible to solve the above problems and increase the dispersibility of the silver nanoparticles. The viscosity is preferably adjusted to at least one selected from the group consisting of casein, sodium carboxymethyl cellulose, and hydroxypropyl methyl cellulose, but is not limited thereto. Latex solids It can be adjusted by adding 0.05 to 0.1wt% relative to the content.
