Description

Cosmetic soap composition containing metal zeolite

The present invention relates to a composition of a cosmetic soap to which a metal zeolite carrying a transition metal ion is added, and more particularly, to a composition of a sterile deodorizing cosmetic soap to remove odor and sweat smell using a metal zeolite.

In general, the washing of the body according to the use of a conventional cosmetic soap has a certain effect on the removal of body odor and sweat odor, but there is a problem that the bacteria residing on the skin is not completely washed out even after washing the body. In addition, the cause of unpleasant odor such as body odor and sweat smell is known to be caused by the oxidation of these bacteria sebum and sweat of the skin. So soap manufacturers are using fungicides such as triclosan or trichlorocarbanilide in the composition of the soap to remove these bacteria and to eliminate body odors and sweat odors when the soap is washed. However, these fungicides may cause discoloration of the soap when used in soap, and may cause skin irritation.

Therefore, the present inventors have studied intensively to sterilize bacteria resident in the skin when using soap and solve the problems of the conventional disinfectant, and when the metal zeolite exhibiting antibacterial and bactericidal effect is added to the cosmetic soap, it is resident on the skin when the soap is used. It was found that the bacteria are significantly reduced compared to the general soap and does not discolor the soap, thereby completing the present invention.

The metal zeolite used in the present invention means that the metal is supported on the zeolite as a metal state after ion exchange of the transition metal to reduce hydrogen, and the metal is silver (Ag), copper (Cu) or ion exchangeable with the zeolite. It is most preferable to ion exchange a cation such as zinc (Zn) alone or in combination, and zeolite may be either natural or synthetic zeolite. General zeolite is aluminosilicate (Alumino-silicate) and has a three-dimensionally developed three-dimensional network structure, excellent selective adsorption characteristics according to the molecular size and good affinity with polar molecules, it is also used as an adsorbent, a desiccant, etc. Also used as a catalyst or ion exchanger. In detergents, the soft water softening effect of the substitution with cations may be used. In addition, general zeolite can be used as a builder in soap, but it has been shown to have no effect as an antibacterial and bactericide. Therefore, the present inventors have found that the use of metal zeolites in cosmetic soaps can effectively remove body odor and sweat odor, as well as bacteria residing on the skin.

The bactericidal effect of the metal zeolite used in the present invention can be explained as follows. When metal ions such as silver or copper or zinc are supported on the zeolite, the outermost electrons of the metal are released and combined with oxygen molecules adsorbed on the zeolite, and the oxygen molecules are electron-charged and activated. This active oxygen is to be a reducing agent because one negative charge enters the oxygen molecule, it is to be an anionic radical having one secondary electron. The antibacterial and bactericidal effects of metal zeolites can be explained by the action of these free radicals. When these free radicals come into contact with the bacteria, they act to damage the cell membranes of the bacteria and exhibit such a reproductive inhibitory effect and ultimately a bactericidal effect. In addition, these metal ions bind to electron donor groups in bacteria, proteins, and hexanes, which inhibit the action of their biomaterials and replace Mg, Mn, and Ca, which are essential ions in vivo. Inhibition of metabolism may have an antimicrobial or bactericidal effect.

The effect of this metal zeolite is the same antimicrobial or bactericidal effect even when used in soap, it shows a very good bactericidal effect in the bactericidal bacteria that reside in the skin when using the soap, ultimately to remove the body odor and sweat smell. In addition, when the metal zeolite exhibits the same soft water softening effect as the general zeolite, it also has the advantage of showing the effect of suppressing the production and improving the feeling of using the soap, and the improvement of the steering power can also be expected.

Hereinafter, the present invention will be described in detail.

The composition of the bactericidal deodorant cosmetic soap of the present invention is characterized in that it contains 0.1 to 20.0%, preferably 0.5 to 15%, of metal zeolite as a bactericide. The amount of the metal zeolite can be increased or decreased depending on the physical properties and the use characteristics of the soap.

Cosmetic soap in the present invention means a general fatty acid soap or synthetic surfactant soap using an alkali salt of a conventional fatty acid as a base or a synthetic surfactant as a base, both fatty acid soap and synthetic surfactant based on Can also be used.

Fatty acid soaps are sodium or potassium salts of fatty acids having 8 to 20 carbon atoms, and fatty acids are obtained from vegetable oils such as palm oil, palm oil, soybean oil, castor oil, olive oil, palm kernel oil, and animal fats and oils such as tallow, pig oil, and fish oil. Used alone or in combination.

In the case of synthetic surfactants, all commonly used surfactants such as sodium lauroyl sulfonate, sodium salt of alkyl benzene sulfonate, sodium cocoyl isethionate, and alkylli salt of acyl glutamate can be used.

The metal zeolite of the present invention is a conventional metal zeolite in which a metal is supported on zeolite as a metal state after ion exchange of a transition metal to reduce hydrogen, and as a metal, silver (Ag), copper (Cu), or zinc (Zn) ) Means single or mixed.

In the present invention, the amount of metal zeolite used is preferably 0.1% or more, and the sterilization effect increases with increasing amount of use, but as the amount of use increases, the foaming power of the soap decreases and the cleaning property is reduced, so the composition of cosmetic soap is 20.0% or more. Is hard to use.

It is also possible to use the usual stabilizers- fragrances and pigments and additives for skin protection in soap compositions.

To compare the bactericidal power of metal zeolites, the culture medium of E. coli and Pseudomonas aeruginosa cultured at 35 ° C. for 20 hours in a normal medium was diluted with physiological saline, and sterile ionized water was added to make a culture solution. One solution was used as a test solution and incubated at 30 ° C. for 6 hours. The results show that the metal zeolite shows excellent sterilization effect as shown in Table 1.

TABLE 1

Next, the present invention will be described in detail with reference to Examples.

Comparative Example 1

Soap was prepared after homogeneous mixing of 98.5 parts by weight of a cosmetic soap, 1.0 parts by weight of perfume, and 0.5 parts by weight of lanolin alcohol in a soap mixer, followed by extrusion through a kneading process.

Comparative Example 2

58.0 parts by weight of cosmetic soap, 1.0 parts of incense burner, 25.0 parts by weight of silver zeolite, 6.0 parts by weight of mineral oil, and 10.0 parts by weight of purified water in a soap mixer, and then extruded through milling and kneading, and then soap. Prepared.

Comparative Example 3

Soap was prepared after homogeneously mixing 98.5 parts by weight of a cosmetic soap, 1.0 parts by weight of perfume, and 0.5 parts by weight of triclosan in a soap mixing machine, followed by a kneading process.

Thus prepared using the cosmetic soap of Examples 1 to 5 and Comparative Examples 1 to 2 are shown in Table 2 by comparing the bactericidal effect, foaming power and degree of soap discoloration.

In the experiment of the bactericidal effect, after a certain amount of Escherichia coli was washed in water flowing with soap prepared by the above Examples and Comparative Examples, which were coated on a certain portion of the upper arm, the E. coli counts before and after washing were shown as a reduction rate. In the experiment, a 0.25% soap aqueous solution was tested by the Ross-Miles method, and the discoloration experiment of the soap was determined by discoloring ultraviolet rays after irradiating the soap for 48 hours.

TABLE 2

Looking at the results shown in the regular table, the bactericidal power of the soap using the metal zeolite is significantly reduced compared to the soap of Comparative Example 1 not used, and shows that the use of only 0.1% of the metal zeolite is effective. In the foaming force, there is a problem that the foaming force decreases as the amount of use increases. Therefore, considering that the foaming force of the conventional soap is preferably 160mm or more, it can be seen that the use of the metal zeolite 20.0% or more is less suitable as a cosmetic soap because the foaming force is lowered. In addition, it can be seen that the soap containing the metal zeolite has an advantage of not causing discoloration of the soap at all compared to the soap of Comparative Example 3 containing the commonly used fungicide triclosan.
