Description

Skin cleanser composition containing mineral complex {SKIN CLEANSING COMPOSITIONS CONTAINING MINERAL COMPLEX}

The present invention relates to a skin cleanser composition containing a mineral complex, and more particularly, it can be produced by washing by containing _four specific mineral salts, that is, a mineral complex consisting of CaCl ₂ , MgCl ₂ , KHCO ₃ and MgSO ₄ . The present invention relates to a skin cleanser composition having excellent moisturizing effect by inducing a rapid recovery of damage to the skin barrier and preventing the loss of NMF (natural moisturizing factor) components in the stratum corneum and preventing skin drying by NMF (natural moisturizing factor) loss. will be.

The skin is divided into epidermis, dermis and subcutaneous tissue. The epidermis has a thickness of about 0.1 to 0.3 cm and has a structure in which cells of the stratum corneum, granule layer, play layer and basal layer are stacked from the upper layer. The most important physiological function of the skin is known to form the stratum corneum, which is a barrier against various external stimuli such as ultraviolet rays and physicochemical stimuli.

The stratum corneum plays an important role in moisturizing the skin due to the presence of a hydrophilic hygroscopic substance called NMF (Natural Moisturizing Factor) as well as defense against external stimuli. The presence of oily components, such as lipids and skin between cells, contributes to the overall skin moisturizing.

However, as human skin ages, the degree of dryness of the skin increases, which is due to a decrease in the normal differentiation capacity of the stratum corneum and a decrease in the natural moisturizing factor (NMF) and lipids due to a decrease in skin barrier function.

As a method for moisturizing the skin, a method of increasing skin moisture retention by temporarily inhibiting evaporation of the stratum corneum through a moisturizing agent such as lipid or oily component on the skin surface is used. However, since the persistence is insignificant, the method of strengthening the intrinsic moisturizing function of the skin by fundamentally smoothing the differentiation ability of the stratum corneum and strengthening the skin barrier function may be a preferable method.

That is, the skin cleanser composition developed to date is largely intended to increase the moisturizing effect by using materials such as polymer compound, polyol, ester oil, fats and oils, and silicone. However, they can simply increase the temporary moisture retention on the skin surface, but it is difficult to expect a continuous moisturizing effect, and in each case there are several problems. Specifically, the polymer compound is widely used as a product for enhancing the stability of the product and as a moisturizer, but has a problem of being slippery when rinsing and sticky after drying. The water-soluble polyol has good rinsing ability but decreases the amount of foam and lowers the viscosity in the O / W formulation. There is a limit to the content due to the stability. Ester oil, silicone, and oils are soft after use, but the amount of foam is reduced, the rinsing property is poor, and the color, flavor and stability of the contents of the product are affected, resulting in a limitation in content.

Minerals are trace elements constituting the human body and are components of NMF (Natural Moisturizing Factor), and are known to activate cells, have a physiological activity, and exhibit skin moisturizing effects. In particular, calcium and magnesium ions are known to contribute to repairing damaged skin barriers (Arch Dermatol res 291 (10): 560-3,1999).

Many attempts have been made to enhance the moisturizing ability by containing minerals based on the above-mentioned skin moisturizing-related mechanisms. Japanese Patent Laid-Open Nos. 62-209009, 2001-72526, and 2001-302444 disclose moisturizing cosmetics containing minerals.

However, when a simple compounding of the mineral as in the prior art as described above may have a certain amount of skin moisturizing effect in the product, the effect was very insignificant.

The present invention has been made to solve the problems of the prior art as described above, by containing a mineral complex consisting of four specific mineral salts to excellently induce the recovery of skin barrier damage NMF (natural moisturizing factor) in the skin It prevents the loss of ingredients and prevents the skin from drying, so it is not only excellent in moisturizing effect but also does not adversely affect the problem of existing moisturizers such as lowering of foam, rinsing, discoloration of product contents, deterioration of fragrance and property stability. The purpose is to provide a composition.

In order to achieve the above object, the present invention provides a skin cleanser composition containing a mineral complex consisting of CaCl ₂ , MgCl ₂ , KHCO ₃ and MgSO ₄ as _four mineral salts in the skin cleanser composition.

Hereinafter, the present invention will be described in more detail.

The skin cleanser composition according to the present invention comprises a base component for giving skin cleansing power and a mineral complex composed of four specific mineral salts.

Specifically, the components constituting the conventional skin cleanser composition, for example, an oily component, water, a surfactant, a thickener, an alcohol, a coloring agent, a fragrance, a preservative, an antioxidant, a whitening agent, various skin nutrients, etc. are appropriately selected. The base component contains a mineral complex composed of four mineral salts. Preferably, one or more moisturizers selected from conventionally known moisturizers such as high molecular compounds, polyols, ester oils, fats and oils, silicones and the like are contained.

In addition, the skin cleanser composition according to the present invention may have various formulations (forms) according to the intended use and use. For example, solid, liquid, gel, powder, emulsion, cream, mousse, paste and the like include any formulation as long as it is used for skin cleansing purposes.

The mineral complex is composed of calcium chloride (CaCl ₂ ), magnesium chloride (MgCl ₂ ), potassium hydrogen carbonate (KHCO ₃ ) and magnesium sulfate (MgSO ₄ ).

According to the present invention, the mineral complex consisting of four specific mineral salts as described above, unlike the simple addition of one or two common mineral salts, not only supplies minerals to the skin but also damages the skin barrier that may occur during skin cleansing. Induces excellent recovery of the skin and significantly reduces the loss of NMF (natural moisturizing factor) components in the stratum corneum and maintains natural moisturizing effect has a superior skin moisturizing effect.

The mineral complex comprises calcium chloride (CaCl ₂ ), magnesium chloride (MgCl ₂ ), potassium hydrogen carbonate (KHCO ₃ ) and magnesium sulfate (MgSO ₄ ) in a weight ratio of 0.00001 to 20: 0.00001 to 20: 0.00001 to 15: 0.00001 to 25. It is preferable that the composition is made (ie, CaCl ₂ : MgCl ₂ : KHCO ₃ : MgSO ₄ = 0.00001 to 20: 0.00001 to 20: 0.00001 to 15: 0.00001 to 25).

In addition, the mineral complex is preferably contained in 0.0001 to 40% by weight based on the total weight of the skin cleanser composition. If it is contained less than 0.0001% by weight can not exhibit the sufficient effect of the skin moisturizing desired in the present invention, if it exceeds 40% by weight is inconvenient in obtaining the desired formulation (form) by lowering the stability of the property .

Hereinafter, the comparative example and the Example of this invention are demonstrated. The following examples are only illustrated to illustrate the present invention in more detail, and the technical protection scope of the present invention is not limited thereto.
