The present invention relates to a cosmetic antibacterial brush, and more particularly to a cosmetic antibacterial brush to prevent the reproduction of E. coli, pneumococcal bacteria, etc. by applying an antibacterial material to the animal hair used in the cosmetic brush.

1 is a photograph showing the shape of a cosmetic brush, cosmetic brush 100 as shown in Figure 1 is a tool for applying a powder or liquid cosmetics to the skin, plastic or wood handle 102 At the end of the) has a structure attached to the brush 106 made of animal hair.

The sole 106 is tightly fixed to the end of the handle 102 by a metal tube 104 or the like.

The cosmetic brush 100 is used while holding the handle 102, soaking the brush 106 in a container, buried cosmetics contained in the container and applied to the cheeks or eyes.

Since the brush 106 of the cosmetic brush 100 is directly in contact with the skin, it is necessary to be made of a soft and cosmetic material that can be well buried, and is usually made of animal hair such as goat hair or horse hair. Is produced.

Brush 106 made of animal hair has the advantage that when the ball touch or eye shadow is soft, cosmetics do not aggregate well spread.

However, when one brush 106 is used for a long time, nutritional ingredients, etc. contained in cosmetics may remain, so that E. coli or other bacteria may propagate. When bacteria are propagated in the cosmetic brush 100, inflammation may be caused to the skin, and bacteria may penetrate into the wounded area, thereby causing a secondary infection, and thus the cosmetic brush 100 needs to be kept clean.

The present invention has been made to solve the above problems, and provides a cosmetic antibacterial brush that suppresses the propagation and proliferation of Escherichia coli, pneumococci, Salmonella, etc. by applying polyhexamethylene biguanide to the brush used in the cosmetic brush It aims to do it.

The present invention for solving the above problems is a brush for applying a powder or liquid cosmetics to the skin, and a plastic handle; A brush made of animal hair material attached to one end of the handle; And a metal tube to fix the brush to the handle, wherein the brush is coated with an antimicrobial material.

The brush is characterized in that it is made of goat hair or horse hair.

의 구조식을 갖는 물질의 중합체인 것을 특징으로 한다.The antimicrobial material is polyhexamethylene biguanide (polyhexamethylene biguanide; PHMB),

It is characterized in that the polymer of the material having a structural formula of.

The sole is immersed in an aqueous solution in which the polyhexamethylene biguanide is dissolved for 5 minutes to 15 minutes, and then dried in a dryer at 30 ° C. to 50 ° C. for 1 hour to 3 hours.

0.5 wt% to 2 wt% of polyhexamethylene biguanide is dissolved in the aqueous solution.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The cosmetic brush of the present invention is coated with an antibacterial agent, the drug used in the embodiment of the present invention is a polyhexamethylene biguanide (Polyhexamethylene Biguanide) is a substance abbreviated as PHMB.

Polyhexamethylene biguanide is added to contact lens disinfectants, wound healing agents, insecticides, etc. and is present in the form of polymers to disinfect or cleanse. Representative structural formulas are as follows.

Polyhexamethylene biguanide is used in the form of an aqueous solution or a water-soluble salt, and 3 to 80 or more biguanides exist in the form of polymerized polymers.

The average value of n in the mixture is generally 12 and the average molecular weight of the polymer mixture is preferably 1100 to 3300.

The organic acid forming the salt with the polyhexamethylene biguanide may contain phosphone, phosphor, sulfone or sulfate groups, but preferably contains carboxylic acid groups.

Polyhexamethylene biguanide is known to have an excellent bactericidal effect against E. coli, Mycobacterium tuberculosis, Salmonella, etc. while being present in the form of an aqueous solution or salt.

In addition, since the structure and manufacturing method of polyhexamethylene biguanide are described in a number of prior applications, including US Patent No. 4,758,595, detailed description thereof will be omitted.

On the other hand, Figure 2 is a flow chart showing the process of the antibacterial treatment to the cosmetic brush, with reference to Figure 2 will be described a method for applying polyhexamethylene biguanide to the cosmetic brush 100.

In order to perform an antibacterial treatment on the cosmetic brush 100, an aqueous solution in which polyhexamethylene biguanide is dissolved is prepared.

It is preferable to dissolve 0.5 to 2% by weight of polyhexamethylene biguanide in the aqueous solution, but in order to increase the antibacterial activity, the ratio of polyhexamethylene biguanide may be increased.

The sole 106 made of animal hair is immersed for a predetermined time in the aqueous solution prepared as described above. (S104) The time for immersing the sole 106 is preferably about 5 to 15 minutes.

When the immersion time has elapsed, the brush 106 is taken out. (S106)

The immersed brush 106 is dried in a dryer at 30 ° C to 50 ° C, and the drying time is preferably about 1 hour to 3 hours. (S108)

While the sole 106 is immersed in an aqueous polyhexamethylene biguanide solution, the bactericidal component is permeated into or on the surface of the animal hair. And it is firmly attached during drying in the dryer to maintain sterilization power for a considerable time.

The polyhexamethylene biguanide treated brush 106 is processed to a certain length in order to adjust the length according to the intended use. (S110)

The brush 106, which has been processed, is attached to the handle 102 using the metal tube 104. (S112) When attaching the sole 106, the metal tube 104 of the portion where the sole 106 is fitted is pressed slightly. It is desirable that the sole 106 does not come out.

After completion of the brush installation, the brush is packed in vinyl and commercially available.

On the other hand, Figure 3a and 3b is a photograph showing the results of the test of the antimicrobial power of the antimicrobial brush, 3a is a result of testing the bacteria propagation state of the brush is not antibacterial treatment, 3b is the antibacterial brush.

This result is the result of the antimicrobial activity (ASTM E 2149-01) test, commissioned to the FITI test institute as of June 12, 2006. The strain used in this experiment was Escherichia coli ATCC 25922 and the initial bacterial count was 2.2 ×. 10 ⁵ (bacterial number / ml). Sorensen's Phosphate Buffer was used as the buffer, and goat hair was used as the material of the sole 106.

The experimental results showed that the bacterial count was reduced to 2.0 × 10 ⁵ (bacterial / ml) after 1 hour without antimicrobial treatment, but almost no difference when the bacteria were treated with antimicrobial treatment to 4.4 × 10 (bacterial / ml). It can be seen that the decrease rate is 99.9%.

Therefore, it can be seen that the brush using the polyhexamethylene biguanide-treated brush has a high antibacterial activity to remove more than 99% of bacteria such as Escherichia coli.

Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and the rights of the person skilled in the art can be easily modified.

According to the present invention, by preventing the growth of bacteria in the cosmetic brush directly applied to the skin to help the beauty of the skin, there is an effect that can prevent the infection caused by bacteria.
