Description

Cleansing composition and manufacturing method for cleansing composition {CLEANSING COMPOSITION AND CLEANSING COMPOSITION MANUFACTURING METHOD}

The present invention relates to a cleansing composition and a method for preparing the cleansing composition, and more particularly, when the present composition having a suitable amount of resorcinol is applied to the skin, sebum secretion is suppressed and the pores are shrunk to have excellent skin softening effect. It relates to a cleansing composition and a method for preparing a cleansing composition that can easily infiltrate keratin, thereby enabling more effective cleansing and inhibiting bacteria due to sulfur components.

In general, the entire surface of the human body is covered with a layer of skin, which is considered the largest organ in the body. The skin provides a barrier layer between the internal organs and the external environment, preventing toxic substances from entering the body and delaying excessive moisture care in the body. The skin also plays an important role in temperature control, vitamin synthesis, secretion, sensory cognition, and processing of antigenic substances.

The skin consists of three important layers of tissue, including the subcutaneous tissue, the dermis, and the epithelium, from inside to outside. The epithelium is the outermost layer of skin, where the living inner layer (the dermal layer) and the nucleus of viable cells are made. It is divided into an outermost laminated sheet (horny layer) consisting of dry and flat keratinocytes.

The lowest cell layer (base layer or embryonic layer) of the epithelium consists of basal cells. Basal cells continually migrate to the surface of the skin, deforming in a process called keratinization and eventually falling off. Directly above the base layer lies a barbed layer. The spine layer consists of several cell layers, and the shape of these spine cells becomes flatter in a direction parallel to the skin surface as they move outwards. Above the spine cells is a granular layer consisting of three cell layers. The granular layer is best developed in areas where keratin is abundantly produced. Keratin is a fibrous insoluble protein that is primarily responsible for the toughness of the outer cover that protects the skin. The next layer is the transparent layer, which consists of cells that are becoming flat, non-nucleated dead cells that make up the stratum corneum. The stratum corneum is formed by cells moving slowly upward from the embryonic basal layer of the epithelium and constantly refills.

Sometimes dry, cracked skin conditions that bother people are characterized by slightly roughening the appearance of the skin's surface and reducing its flexibility. This condition is called dryness, a condition in which the skin loses its flexibility and cracks and fissures form. One of the factors causing this condition is environmental factors. Reduced humidity causes loss of moisture on the skin surface, dry and cold winds promote evaporation by convection, and low temperatures reduce the extensibility of the stratum corneum. The use of synthetic detergents also promotes the drying of the stratum corneum. The physical appearance of the skin depends entirely on the condition of the stratum corneum. This supports the low water content of the stratum corneum which is the most important factor causing dry skin.

Conventional skin care products to address the various skin problems mentioned above can be used to prevent excessive moisture loss and to restore high moisture content of the stratum corneum. Softeners and moisturizers are used in cosmetics to treat dry skin conditions. (moisturizer) There are two types.

Emollients, often called skin conditioners, enhance or maintain hydration by lubricating or occluding the skin surface.

Moisturizers contain humectants that induce moisture into the skin to hydrate or restore the stratum corneum.

However, the conventional products have a problem that it is difficult to penetrate the skin keratin and the oxygen absorption is difficult, as well as the softening, moisturizing, antiviral effect is insufficient and the effect is also not persistent.

The present invention is to solve the above-mentioned problems, the object is to reduce the secretion of sebum when applied to the skin the composition of the resorcinol in an appropriate amount to shrink the pores, excellent skin softening effect, easy to exfoliate skin By providing an effective cleansing, not only to inhibit the bacteria due to sulfur components, but also to provide a cleaning composition and a method for producing a cleansing composition that maintains a continuous skin protection effect.

1 is a process chart for explaining the manufacturing method of the cleaning composition of the present invention.

Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

As described above, conventionally, skin care products are difficult to penetrate the skin keratin and difficult to absorb quickly, as well as the softening, moisturizing, antiviral effect is insufficient and the effect is also not sustained, to solve this problem In order to increase the ratio of resorcinol, which is a PH regulator by a certain ratio, the present inventors have an excellent skin softening effect by inhibiting sebum secretion and shrinking pores when applying the present composition having a proper amount of resorcinol to the skin. It is easy to exfoliate keratin effectively and effective cleaning, it is possible to produce a cleaning composition that not only functions to inhibit bacteria due to sulfur components, but also maintains skin protection effect continuously.

In the cleaning composition of the present invention, sulfur (S) is 5% by weight, zinc oxide (ZnO) is 10% by weight, talc is 30% by weight, resorcinol is 2-5% by weight, glycerin (Glycerin) contains 7% by weight, ethanol 10% by weight, sodium carboxymethyl cellulose (CMC Na) 9% by weight, purified water contains 22-25% by weight.

Looking at the manufacturing method of the cleaning composition of the present invention, the first step of heating the appropriate amount of purified water to 80 ℃ or more, and put zinc oxide, sulfur, talc in the heated purified water and stirring for a proper time; A second step of dissolving resorcinol in an appropriate amount of purified water warmed to 80 ° C. or more, and then adding the dissolved resorcinol to the mixture prepared in the first step and stirring for a proper time; A third step of adding glycerin and propylene glycol to the mixture made in the second step and stirring for an appropriate time; Adding a swelled carboxymethylcellulose sodium to the mixture made in the third step and stirring; And a fifth step of adding ethanol to the mixture made in step 4 and stirring.

In the method for preparing the cleaning composition, sulfur 5 wt%, zinc oxide 10 wt%, talc 30 wt%, resorcinol 2-5 wt%, glycerin 7 wt%, ethanol 10 wt%, carboxymethyl Sodium cellulose is 9% by weight, purified water is characterized in that 22-25% by weight.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a block diagram showing the cleaning composition and the manufacturing process of the cleaning composition, in the first step, 22-25% by weight of purified water warmed to 80 ℃ or more, and added zinc oxide, sulfur, talc to the purified purified water and stirred for about 2 hours do.

Zinc oxide, sulfur, and talc are insoluble in water because of their characteristics.

Zinc oxide and sulfur are included in the present invention the most important constituents in the cleaning composition 10% by weight, 5% by weight, talc 50% by weight.

In the second step, resorcinol 2-5% by weight is dissolved in an appropriate amount of purified water warmed to 80 ° C. or higher, and the dissolved resorcinol is added to the mixture prepared in the first step and stirred for about 2 hours.

In the third step, 7% by weight of glycerin and 3% by weight of propylene glycol are added to the mixture prepared in the second step and stirred for about 2 hours.

In the fourth step, swelled carboxymethylcellulose sodium is added to the mixture made in the third step and stirred.

Carboxymethylcellulose sodium has the property of naturally swelling in purified water (80 ° C).

In the fifth step, ethanol is added to the mixture prepared in step 4 and stirred.

The talc mentioned above acts as an emulsifier, resorcinol plays a role in controlling pH, and propylene glycol, glycerin, ethanol and purified water serve as solvents.

Ethanol may be added together with other solvents propylene glycol and glycerin, but it is preferable to add solvent at the end of the process.

Hereinafter, the embodiment will be described.
