Abstract

PURPOSE:To provide a cosmetic applicable safely and continuslly for a long period, by using a germanium-containing substance having low toxicity to human body and having biophylactic activity and homeostasis-promoting activity, etc. CONSTITUTION:Elemental germanium or a germanium derivative [e.g. oxide, hydroxide, halide or organic compound (e.g. alkylate, arylate, etc.), preferably a water-soluble compound] is used as a component of a cosmetic to be applied to the skin, e.g. face lotion, cream, milky lotion, soap, face powder, foundation, lipstick, rouge, eye makeup, pack, etc. When the cosmetic prepared thereby is applied to the skin, hair or oral cavity, it exhibits excellent effect to activate the tissue, keep its freshness, and supply the tissue with nutrients.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cosmetic products containing germanium-containing substances.

Recently, as research on germanium, particularly organic germanium, has progressed, it has become known that it has antitumor and antiviral effects, and has biological defense and homeostasis promoting effects as a medicinal agent. Moreover, the advantage is that it has almost no toxicity. On the other hand, since conventionally used cosmetics, especially cosmetics applied to the skin, are directly applied to the cells of living organisms, many substances often act as foreign substances and exert harmful effects on the skin. For this reason, various materials and methods have been repeatedly investigated, but nothing satisfactory has yet been found.

The inventor of the present invention conducted studies to improve the drawbacks of this cosmetic product and found that excellent cosmetic products can be obtained by utilizing the effects of germanium as described above.

That is, the present invention relates to cosmetics containing germanium.

The germanium-containing substance used in the cosmetics of the present invention is germanium alone or its derivatives, such as oxides, hydroxides, halides, or organic compounds such as alkylated products, arylated products, [(GeCH2CH2C○0H)20
5). They may be insoluble or soluble in the solvent, but water-soluble ones are particularly preferred. The amount used varies depending on the type of cosmetics, so it cannot be said generally, but for example, for lotions it is 0.1 to 0.00% by weight, and for creams it is 1 to 0.00% by weight.
It is 1% by weight.

The types of cosmetics of the present invention include conventionally used cosmetics, such as basic cosmetics, makeup products, hair cosmetics, and oral hygiene products.

Among them, cosmetics that are especially applied to the skin, such as lotions, creams, milky lotions, soaps, powders, foundations, etc.
It is extremely effective on lipstick, rouge, eye makeup, face packs, etc. The composition of the cosmetic product of the present invention is achieved by adding a specific amount of germanium to the ingredients constituting conventional cosmetic products.

In manufacturing the cosmetics of the present invention, conventional methods for manufacturing cosmetics can be used (no special methods are required. White petrolatum, stearyl alcohol) 70-80
Heat to melt at ℃, add fine powder of germanium to water phase components (propylene glycol, sodium lauryl sulfate, ethyl paraoxybenzoate, propyl paraoxybenzoate, purified water), heat to 70-80℃, and stir. It can be made by adding it to the oil phase little by little while cooling it gradually. Taking the production of lotion as an example, polyoxyethylene cetyl ether, fragrance, and preservatives are dissolved in ethanol, purified water is added, and then citric acid, sodium citrate, pigment, and germanium fine powder are added. The obtained solution is added little by little to a homogeneous mixture of propylene glycol alginate and glycerin and mixed with stirring to obtain the desired product.

The cosmetics of the present invention contain germanium, which has the above-mentioned excellent effects, so when applied to human skin, hair, or oral cavity, it activates them, maintains youthfulness, and provides nutrition, resulting in excellent effects. can be mentioned. Furthermore, germanium and its conductors have extremely low toxicity to the human body and do not cause any damage to the skin (as they are extremely safe compounds, they can be used safely in cosmetics, and can be used for long periods of time [B1]). can.

Next, examples will be shown.

Example 1 Production of neutral cream (oil phase component) White petrolatum 25.0? Stearyl alcohol 22. Or (aqueous phase component) Propylene glycol 12. Or Sodium lauryl sulfate 1.51 Ethyl paraoxybenzoate 0.002Fl Propyl paraoxybenzoate 0.015P germanium fine powder
0.015' Add purified water to make 100.0SF oil phase component 70
It was heated and melted at ~80°C. On the other hand, after heating the aqueous phase component to the same temperature, it was added little by little to the oil phase component while stirring and gradually cooled.

Example 2 Production of emulsion (oil phase component) Stearic acid 20% Lanolin 2.0% 2-octyldodecanol 16.0% Sorbitan monostearate 0.5% (aqueous phase component) Triethanolamine 1. 0% carboxyvinyl polymer 0.2% propylene glycol 4.0% [(Ge -CH2・CH2・C00H)203]□Fine powder 0.005qA fragrance Appropriate amount Preservative Antioxidant Add purified water 100.0φ The oil phase component was heated and melted at 70 to 80°C. Preservatives and antioxidants were then dissolved. On the other hand, triethanolamine, propylene glycol, and a germanium compound were added to a portion of the purified water, heated to the same temperature, and added little by little to the oil phase while stirring. Further, a dispersion of carboxyvinyl polymer in water and a fragrance were added and gradually cooled.

Apply an appropriate amount of the obtained emulsion to the skin of the face and hands twice a day2.
After a few months, the surface of the skin became smoother, wrinkles disappeared, and most of the spots disappeared. Even after continuous use for one year, no irritation occurred on the skin and no damage occurred.
