Description

[0001] Natural mineral powders and cosmetic or clothing products containing them [0001] The present invention relates to natural mineral powders and cosmetic or clothing products containing the same,

The present invention relates to a natural mineral powder and a cosmetic product or an article of clothing comprising the same, more specifically, to an effect of skin regeneration, moisturizing, elasticity enhancement, whitening, etc. and effects such as far infrared radiation, antibacterial, deodorant or deodorization, Natural mineral powders and cosmetics or clothing products containing them.

In modern society, large amounts of active oxygen are generated by ultraviolet rays and water pollution due to exhaust gas, toxic chemical substances, destruction of ozone layer, etc. Such active oxygen penetrates into human body and causes various side effects. In particular, And the like.

In addition, in recent years, outdoor leisure activities such as golf have been increasing in order to overcome the excessive social and work stress. During the leisure activities in such occasions, the body skin is more easily exposed directly to the above pollution sources, And skin aging can not be avoided. This has a negative effect on the tendency to enjoy outdoor leisure activities more positively and comfortably.

In general, skin plays a primary role in preventing harm from various external factors that interfere with our homeostasis through basic metabolic processes. In other words, while the skin is located at the outermost position of the body, it plays various roles such as protection through physical, chemical and biological barrier functions, body temperature regulating action, sensory action, secretion and excretion action, absorption action, storage action and regeneration action , And most likely to be damaged if sustained external stress is applied.

Typical examples of such external stresses are ultraviolet exposure, (fine) dust, exhaust gas, dust, environmental pollutants, heavy metals, temperature changes, microorganisms, and they are mainly activated by oxidative stress By creating reactive oxygen species (ROS), it destroys the antioxidant defense system, causing cell damage and death.

On the other hand, today, oriental women prefer white, clean skin like white whiting and use it as an important criterion of beauty. Therefore, development of whitening agent for treatment of skin pigmentation abnormality and for satisfying beauty desire is actively carried out. For example, Substances that inhibit tyrosinase, an enzyme involved in skin blackening process, or inhibit melanin polymerization reaction, are used in cosmetics. Representative materials used for this purpose include hydroquinone, ascorbic acid, kojic acid, thiol compounds such as glutathione and cysteine, and alpha hydroxy acids.

However, most of these ingredients are known to be unstable in themselves, have a weak whitening effect, and also cause skin irritation. In addition, natural extracts known to have a whitening effect contain a small amount of active ingredient, and it is difficult to obtain a homogeneous quality of deep quality by varying the content depending on the origin and harvesting date. Various kinds of compounds are extracted together, .

In addition, since proper moisture content of the skin is an essential factor for maintaining a normal skin condition, studies on skin moisturizers for maintaining the moisture content of the skin have been continuously carried out. Conventional skin moisturizers simply moisturize the skin, Can be maintained temporarily.

However, these moisturizers penetrate deeply into the skin through the epidermis, and there is a very low ability to fix moisture in the stratum corneum which is easy to dry and has a barrier to moisture, so that the skin moisture content is maintained to an appropriate level It was a problem of difficulty.

In addition, in order to change and maintain the skin to the best condition, it is necessary to delay the aging process of the skin and prevent the skin from being damaged. For this purpose, it is necessary to prevent the transdermal water loss and to sufficiently moisturize the skin, , It is important not only to minimize the progression of aging, but also to promote skin elasticity, wrinkle and skin troubles at the same time. However, cosmetic compositions capable of satisfying all of these effects have not been developed yet.

On the other hand, mineral powders have a fine particle size of tens or hundreds of micrometers, have a large specific surface area and have strong adsorption properties, and most mineral powders have physicochemical properties such as ion adsorption power, swelling power, And it is highly valuable as a raw material or additive for cosmetics or pharmaceuticals.

Particularly, when the physical and pharmacological properties such as the viscosity and swelling power of the mineral powder are utilized, the cosmetic preparation or the preparation intended for topical application can be prepared as a suspension, a gel or a semi-solid. Usually, the powder is suspended in an aqueous solution Or a cream base containing an oil / water emulsifier, and in addition, it is widely used as a preparation for skin in the case of a mineral powder having a skin protection effect (Non-Patent Document 1).

Despite the useful physico-chemical performance of these mineral powders, the performance of different mineral powders, which can be expressed differently depending on their composition and composition or manufacturing process, has not yet been studied. Further research is required on the relationship with the concrete physical properties required.

Particularly, when it is used as an additive for clothing products, studies on the composition, composition and manufacturing process of natural minerals should be more closely conducted in order to maximize the performance of far-infrared radiation, deodorization, and antibacterial activity.

Far-infrared radiation dose test

The far-infrared radiation dose was tested for the natural mineral powder composition prepared in Example 1, and the paper and film prepared above. As a result, both the far infrared ray powder composition and the panties containing the far infrared ray powder composition emitted far infrared rays. Which are shown in Fig. 1 (Secret-7 powder) and Fig. 2 (Secret-7 powder panty), respectively.

Manufacture of sample fabrics for deodorization and antibacterial test

A sample fabric for deodorizing and antibacterial testing was prepared by printing a knitted fabric of 100% cotton with a silicone ink containing the natural mineral composition according to Example 1 above.

Antibacterial test

The antimicrobial activity of the sample fabric prepared above was tested. Staphylococcus aureus (ATCC 6538) and Klebsiella pneumoniae (ATCC 4352) were used. TWEEN 80 (0.05%), a non-ionic surfactant, was used and the results are shown in Figures 3a, 3c and 3d below.

As a result of calculating the bacteriostatic reduction rate by measuring the number of remaining bacteria after inoculation of each of the above two strains and culturing for 18 hours, it was confirmed that they showed very high antimicrobial activity exceeding 99.9% for both strains.

Deodorization test

The fabric prepared above was tested for deodorizing function according to the Japan Textile Testing and Consulting Association Test (JTETC). Specifically, a sample cloth of 10 cm × 10 cm was placed in a 5 L tetra bag, and 3 L of gas adjusted to an initial concentration was injected. After 2 hours, the gas concentration was measured with a detector tube (use detector tube: ammonia 3 La).

As a result, as shown in FIG. 3B, it was confirmed that the sample fabric including the natural mineral composition according to the present invention exhibited a very excellent deodorizing function for the two test gases, ammonia and acetic acid.

Infrared thermal camera shooting

The front surface of the subject's body was photographed using an infrared thermography camera (FLIR System, P25) with the panties fabricated with the above-described sample fabric worn or demolded, and the results are shown in Figs. 4A to 4D.

As a result, the body temperature was elevated with time after wearing the panties coated with the natural mineral composition according to the present invention, and thus the blood circulation improving effect of the natural mineral composition was confirmed.

Analysis of natural minerals

The components of the natural mineral composition according to Example 1 were analyzed using X-ray diffraction (XRD) qualitative analysis, and the results are shown in FIGS. 5A and 5B.
