Description

  The present invention relates to a cosmetic product for keeping skin clean, and particularly to a cosmetic product that can exhibit excellent antiseptic, sterilizing, cleaning, deodorizing, and anti-inflammatory effects due to the effects of a photocatalyst and an apatite complex.

  In recent years, the number of people with skin diseases such as sensitive skin and atopic dermatitis has been increasing. For this reason, the ingredients contained in cosmetics are required to be more gentle to the skin and more effective than those that must be applied directly to the skin.

  In order to prevent skin diseases and skin troubles, it is important to keep the skin clean and suppress the growth of germs. For this purpose, cosmetics usually have a lot of antiseptics, antiseptics, and anti-inflammatory agents as a cosmetic base. Contains chemicals. However, many of these substances themselves have skin irritation and toxicity, and conversely, they often cause skin diseases and skin troubles. Therefore, development of cosmetics that are gentle on the skin, safe, and sufficiently effective in preserving and sterilizing has been awaited.

  In view of the above-described conventional problems, an object of the present invention is to provide a cosmetic that can exhibit excellent antiseptic, sterilizing, cleaning, deodorizing, and anti-inflammatory effects due to the effects of the photocatalyst and the apatite complex.

  For this reason, this invention provides the cosmetics characterized by containing the composite particle of a photocatalyst and apatite.

  Here, the composite particles of the photocatalyst and apatite are preferably composite particles in which the photocatalyst particles are coated with apatite. Alternatively, the composite particles of the photocatalyst and the apatite are preferably composite particles in which the photocatalyst is substituted in the crystal structure of the apatite.

  The photocatalyst is mainly composed of one or more of titanium dioxide, zinc oxide, vanadium oxide, dibismuth trioxide, tungsten trioxide, iron oxide, strontium titanate, and cadmium sulfide. Further, the apatite is preferably fluorinated apatite or hydroxide apatite.

  Moreover, you may further contain the activator which activates the disinfection and bactericidal action of the said photocatalyst element. The activator is preferably one or more of sodium percarbonate, sodium perborate, sodium carbonate or sodium bicarbonate.

  It may also contain plant essential oils obtained from one or more of the natural plants including lavender, rosemary, sweet orange, cedarwood, chamomile and peppermint.

  It may also contain a moisturizing material obtained from one or more of natural materials including beeswax, honey, coconut milk powder, seaweed, brown sugar, yogurt, egg yolk.

  The cosmetic is preferably any one of a makeup cleansing agent, a face wash, a lotion, a cosmetic liquid, an emulsion, a cream, and a pack.

  According to the present invention, the apatite of the photocatalyst and the apatite complex adsorbs harmful chemical substances, malodorous substances, bacteria, etc., and the photocatalyst decomposes and removes them, thereby providing excellent antiseptic, sterilizing, washing and erasing. It can be set as cosmetics which have an odor and an anti-inflammatory effect.

  Here, when the photocatalyst is combined with apatite, the above-described various pharmacological actions can be exhibited even if a large amount of light is not continuously irradiated. Moreover, the action continues without decreasing until the cosmetic is used up. Therefore, according to the present invention, it can be stored for a long time without adding preservatives and antibacterial agents, and adsorbs, decomposes and removes dirt on the pores and bacteria attached to the skin, and eliminates the smell of sweat and body odor. It can be made into a cosmetic that can soothe inflammation such as acne and allergies and can also improve skin troubles.

  In addition, titanium dioxide contained in the cosmetics of the present invention is an abundant element on the earth, and apatite has also been used for artificial bones, artificial roots, foods, cosmetics, etc. In addition, since it is a safe and harmless material, it can be used as a cosmetic that can be used with confidence without causing environmental pollution or adverse effects on the human body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram illustrating the functions of a photocatalyst and an apatite composite contained in the cosmetic of the present invention.

The cosmetic product of the present invention contains a photocatalyst and an apatite complex. First, the apatite used in the present invention is M ₁₀ (ZO ₄ ) ₆ X ₂ with M, Z, and X as optional elements. It is a group of minerals having a composition, and is called apatite in the Japanese name. Here, the main components of M and Z are calcium and phosphorus, respectively, but M, Z, and X can be replaced with various elements relatively easily. When calcium is contained in M, phosphorus is contained in Z, and fluorine is contained in X, fluorinated apatite (fluoroapatite) is obtained. In addition, when calcium enters M, phosphorus enters Z, and a hydroxyl group enters X, it becomes hydroxyapatite (hydroxyapatite).

  This apatite has a function of adsorbing and holding dirt, odor, bacteria, and other harmful chemical substances. For example, it can adsorb bacteria and viruses such as nitrogen oxides, lipid peroxides, ammonia, aldehydes, and Escherichia coli.

  On the other hand, the photocatalyst has an action of decomposing and removing the dirt, odor, bacteria and the like adsorbed by the apatite by an oxidation-reduction action when irradiated with light.

  In the cosmetic of the present invention, such a photocatalyst and apatite are combined and added by a method such as coating (covering the photocatalyst with apatite), substitution (substituting the photocatalyst in the crystal structure of the apatite), and the like. Thereby, the action of both the apatite and the photocatalyst can be coordinated, and safe, harmless, antiseptic, sterilizing, cleaning, deodorizing, and flameproofing effects can be exhibited.

  For example, a photocatalyst can generate very strong oxidizing power when exposed to light, decomposes harmful chemical substances, bacteria, mold, odors, dirt, etc. that come in contact with it, and can be decomposed and removed to carbon dioxide. Since there is no action of attracting or adsorbing a large amount of these substances, bacteria, etc., only substances that contact the surface of the photocatalyst can be decomposed, and they cannot function unless exposed to light. On the other hand, apatite is also excellent in the ability to adsorb proteins and substances and can be adsorbed in large quantities. However, since there is no such resolution, if it exceeds a certain adsorbed amount, it will be saturated and no more adsorbed.

  However, when the photocatalyst and apatite are combined, as shown in FIG. 1 (a), the substance can be adsorbed even if it is not exposed to light. Further, as shown in FIG. 1 (b), the apatite is adsorbed when there is light. Since the photocatalyst is decomposed, the adsorption function is regenerated each time. Furthermore, although the photocatalyst requires a certain time to decompose the organic substance, apatite does not escape the adsorbed substance, and thus has an effect that it can be reliably decomposed.

  For this reason, the cosmetics of the present invention can exhibit antiseptic, sterilizing, cleaning, deodorizing, and anti-inflammatory effects even with slight light. In addition, since the action is continued until the cosmetic is used up without decreasing, it can be stored for a long time without adding a preservative or an antibacterial agent.

  As the apatite used in the present invention, chloroapatite, carbonate apatite, carbonated hydroxyapatite and the like are preferable in addition to the above-mentioned fluorinated apatite and hydroxide apatite.

  As the photocatalyst used in the present invention, titanium dioxide, zinc oxide, vanadium oxide, dibismuth trioxide, tungsten trioxide, iron oxide, strontium titanate and the like are suitable.

  Furthermore, when sodium percarbonate, sodium perborate, sodium carbonate or sodium bicarbonate (sodium hydrogen carbonate) is added to the cosmetic of the present invention, the photocatalyst is activated, so that the resolution can be further enhanced.

  The photocatalyst and apatite composite of the present invention can be mixed with various cosmetic base materials. For example, if it is added to a makeup cleansing agent, facial cleanser, or pack, makeup stains or sebum stains can be removed from the pores, bacteria that adhere to the skin can be decomposed, and the skin can be kept clean. In addition, it can be used in lotions, beauty lotions, milks, and creams to maintain the function of degrading sebum stains and germs until it is washed away, improving and preventing skin problems such as acne and allergies, and maintaining a deodorizing effect. . Furthermore, the addition of preservatives and antibacterial agents can be minimized or eliminated in any cosmetic base material.

  A moisturizing agent may be added to the cosmetic of the present invention. As this humectant, natural materials including beeswax, honey, coconut milk powder, seaweed, brown sugar, yogurt, and egg yolk can be used.

  In addition, plant essential oils such as lavender, rosemary, sweet orange, cedarwood, chamomile and peppermint may be added.

  Thus, according to the present invention, the apatite of the photocatalyst and the apatite complex adsorbs harmful chemical substances, malodorous substances, bacteria, etc., and the photocatalyst decomposes and removes them, thereby providing excellent antiseptic, sterilizing, It can be set as the cosmetics which have a washing | cleaning, deodorizing, and a flame-proofing effect.

  Here, when the photocatalyst is combined with apatite, the above-described various pharmacological actions can be exhibited even if a large amount of light is not continuously irradiated. Moreover, the action continues without decreasing until the cosmetic is used up. Therefore, according to the present invention, it can be stored for a long time without adding preservatives and antibacterial agents, and adsorbs, decomposes and removes dirt on the pores and bacteria attached to the skin, and eliminates the smell of sweat and body odor. It can be made into a cosmetic that can soothe inflammation such as acne and allergies and can also improve skin troubles.

  In addition, titanium dioxide contained in the cosmetics of the present invention is an abundant element on the earth, and apatite has also been used for artificial bones, artificial roots, foods, cosmetics, etc. In addition, since it is a safe and harmless material, it can be used as a cosmetic that can be used with confidence without causing environmental pollution or adverse effects on the human body.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, Based on the meaning of this invention, various deformation | transformation are possible, These are excluded from the scope of the present invention. is not.

  The present invention relates to cosmetics for keeping the skin clean, and in particular, to cosmetics that can exhibit excellent antiseptic, sterilizing, cleaning, deodorizing, and anti-inflammatory effects due to the effects of the photocatalyst and the apatite complex, and industrial use Have potential.
