Abstract

Natural or synthetic zeolite is dipped in aqueous solution of antibiotic metal like silver, copper, zinc or etc. and does ion-exchange reaction. After that, it is washed and dried until ionic ingredient of the dipped aqueous solution is not detected to do the ion exchange of antibiotic metal. Zeolite ion exchanged by antibiotic metal is used as antiseptic in the whole cosmetic using cosmetic powder.

Description

Cosmetic composition containing antimicrobial zeolite

The present invention relates to a cosmetic composition containing a zeolite in which an antimicrobial metal is ion-exchanged, and more particularly, to a cosmetic composition having excellent antibacterial effect by ion-exchanging a metal having antimicrobial properties in a synthetic and natural zeolite and containing the same in a zeolite. It is about.

Although zeolites have been used in various ways for a variety of purposes, there have been no examples of using zeolites in various cosmetic applications. In other words, the purpose of imparting the antibacterial effect of cosmetics by introducing a compound having antimicrobial properties to synthetic and natural zeolites into the cosmetic composition by introducing zeolites ion-exchanged with alkali metals present in the zeolite has not yet been achieved. In the field, there are sanitary fibers, antimicrobial materials, water filters and the like using antimicrobial materials.

The present inventors have diligently studied the specific structural properties of the zeolite and the method of utilizing the ion exchange ability. As a result, the antimicrobial metal is effectively incorporated into the zeolite skeleton structure by using the excellent ion exchange ability with the alkali metal in the three-dimensional porous framework of the zeolite. By ion exchange and adsorption, it contains an antimicrobial zeolite with excellent antiseptic and antimicrobial effect by antimicrobial metal, and blends it into a cosmetic composition to provide a cosmetic with excellent antiseptic and antimicrobial effect without using general antiseptic preservatives in the cosmetic composition. It was completed.

In the present invention, the zeolite for ion exchange is Anaalme, Fajasite, Chabazite, Natrolite, Philipsite, Mordenite Natural zeolites of type A and NA, X or Y, HS (hydroxy sodalite) ZK-5, B (PI), Synthetic zeolites such as type, S type, R or G or D type, T type, L type, W type, Zelon type and C type are used, and the chemical formula of such zeolite is xM _{2 / n} O. Al ₂ O ₃ ySiO ₂ zH ₂ O. However, the kind and form of such zeolites do not limit the effects of the present invention.

The present invention will be described in detail as follows.

A solution of a water-soluble salt of an antimicrobial metal such as silver, copper, zinc, or the like in a natural or synthetic zeolite, ie, silver nitrate, silver carbonate, copper sulfate, copper chloride, nitrates such as zinc equivalent, zinc chloride, zinc carbonate, carbonate, sulfate, chloride, etc. The zeolite was immersed in the dissolved aqueous solution, and the ion exchange reaction was performed for 2-5 hours at room temperature or warmed to about 50-80 ° C., and then washed and dried until the ionic component of the immersed aqueous solution was not detected. Make a zeolite.

By the ion exchange reaction, the ions of Ag, Cu, and Zn are exchanged with and adsorbed to monovalent sodium (Na) ions present in the zeolite, thereby being present in the framework of the zeolite. The strength of the adsorption exchange capacity of these ions is generally larger as the number of valences is large, and the same valence varies depending on the type and atomic group of ions. External ions exchanged with sodium ions, like sodium ions, are chemically adsorbed, so they are not easily desorbed and are slowly released to the outside.

The throughput of the antimicrobial metal treated with zeolite by the method of ion exchange reaction varies depending on the treated metal and the type of salt used, but is preferably 0.0001-5.0 parts by weight, more preferably 0.5-5.0 parts by weight. will be.

Zeolites ion-exchanged with antimicrobial metals as described above can be used as preservatives in all cosmetics using cosmetic powders, and organic preservatives have a problem of excessive blending due to the decrease in concentration due to the type of surfactant, pH, and adsorption in the product formulation. It removes and gives better antibacterial effect than organic preservative.

On the other hand, cosmetics that can be used as inorganic pigments include powder foundations, compacts, two-way cakes, and face powders, as well as eye shadow, powder blush, mascara, lipstick, lip gloss, lip pencil, eyeliner, and eyebrow pencil. Partial cosmetics such as cosmetics, emulsified foundations, cosmetics such as makeup base, packs such as powder packs and klingsing packs, some basic products such as sunscreen creams, creams, lotions and lotions and whole body such as baby powder body powder It can be divided into products and the like, and the inorganic pigments blended into these products are contained at a minimum of 0.1 parts by weight to as high as 100 parts by weight.

Therefore, the antimicrobial zeolite can be used as an inorganic preservative which can impart antimicrobial effect to all cosmetics using the same powder as described above, the compounding amount is preferably 0.01-30.0 parts by weight, more preferably 0.1-20.0 parts by weight. .

Hereinafter, the present invention will be described in detail with reference to Examples and Examples and Comparative Examples for preparing the antimicrobial zeolite.

[Reference Example 1 of Preparation of Antimicrobial Zeolite]

Dissolve 3.0 g of silver nitrate in 300 ml of purified water to make an aqueous solution. Disperse 100 g of X-type zeolite with an average particle diameter of 10 μm, stir at rpm 300 for 5 hours at 25 ° C., precipitate, and discard the supernatant. After the washing was repeated until no residual silver ions were detected by adding and washing, the precipitate was dried at 100 ° C. to obtain a zeolite in which silver was ion-exchanged. The detection of residual silver ions was determined by adding diluted hydrochloric acid and droplets to the collected supernatant to form white precipitates.

Dissolve 5.0 g of copper sulfate in 300 ml of purified water to make an aqueous solution. Disperse 100 g of mordenite zeolite with an average particle diameter of 100 μm, stir at 25 ° C. for 5 hours at 25 ° C., precipitate, and discard the supernatant. In addition, 300 ml of purified water was added again and washed until no residual copper ions were detected. Then, the precipitate was dried at 110 ° C. to obtain a zeolite in which copper was ion exchanged. The detection of residual copper ions was determined by the addition of a few drops of potassium cyanide (11) potassium cyanide solution to the collected supernatant to produce orange to chocolate precipitates.
