Description

Soap for removing keratin comprising pumice as an active ingredient {Soap for removing keratin comprising of pumice as an active ingredient}

The present invention relates to soap and the like containing pumice as an active ingredient.

Common soaps are produced through saponification of higher fatty acids and sodium or potassium hydroxide obtained by decomposing oils and fats derived from animals and plants. These fatty acid soaps are easy to manufacture, and raw materials such as fatty acids, sodium hydroxide, potassium hydroxide, and oil are inexpensive. In addition, it has the advantage of being easy to improve functionality (for example, jojoba oil has a moisturizing function and coconut oil has cleansing power) through mixing with natural oils and fats.

Since this fatty acid soap contains a dead skin exfoliant, it is possible to obtain a scrub effect, that is, an exfoliating effect of the skin, by rubbing it on the skin such as the face as if massaging the soap itself. Scrubs used to show the scrub effect in the soap manufacturing process can be classified into physical exfoliants and chemical exfoliants. As chemical scrubs, chemical substances such as salicylic acid that dissolve dead skin cells are used, and beads (beads) through polymer synthesis are used. ) type of physical and artificial scrubs or physical natural scrubs, which are pulverized powders of hard natural grains, are mainly used.

In the case of chemical artificial scrubs, the amount used is limited due to excessive stimulation or side effects due to many chemical components that are not good for the skin or eyes. Exfoliation through a physical natural scrub agent is preferred, and the demand for a soap containing a natural scrub agent is continuously increasing.

Currently, many natural grains, which are one of the raw materials for cosmetic soaps and cosmetics, have starch (starch) as the main ingredient, and this starch ingredient actually performs the function of a scrub agent. However, the starch applied to the actual exfoliating product has a problem in that the water molecules are absorbed into the starch crystals by contact with water, and the strength of the molecules becomes softer and the effect of exfoliating the dead skin decreases. There is a problem in that the viscosity of the starch weakens the hardness of the soap, making it difficult to maintain the soap form. In addition, in the case of natural grains, as they are basically a food ingredient, they are in high demand, so they are expensive and there is a problem that the price is high when used as a raw material for cosmetic soap or cosmetics.

Therefore, in the case of soap that generates bubbles by contact with water and rubs it on the skin, it is a natural scrub that maintains the bonding force between molecules even when it comes into contact with water. There is an urgent need to develop a cosmetic soap composition containing a raw material and a cosmetic soap using the same.

The technical problem to be achieved by the present invention is to provide a soap for exfoliating a dead skin cell comprising permis as an active ingredient and a method for manufacturing the same.

However, the technical problem to be achieved by the present invention is not limited to the above-mentioned problems, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to solve the above problems, the present invention provides a soap for exfoliating dead skin cells comprising pumice as an active ingredient.

In one embodiment of the present invention, the soap may further include walnut shell powder.

As another embodiment of the present invention, the soap may further include coconut oil (Coconut Oil) and Western rapeseed oil (Brassica Napus Seed Oil).

In another embodiment of the present invention, the soap is lauric acid, myristic acid, palmitic acid, stearic acid, sodium hydroxide, glycerin, sorbitol, and hyaluronic acid.

In addition, the present invention provides a method for preparing a soap for exfoliating a dead skin cell comprising the following steps (1) to (7):

(1) soap base manufacturing step;

(2) stirring the soap base at 50° C. using a stirrer;

(3) Coconut Oil (Coconut Oil) and Western rapeseed oil (Brassica Napus Seed Oil) are mixed and heated to 50 ℃, and then the first additive manufacturing step of further mixing cocobetain (Cocobetain);

(4) The first additive of step (3) is mixed with the soap base after step (2) and stirred for 5 to 15 minutes, then sodium hydrogen carbonate and sodium chloride are additionally mixed and stirred so that the powder is not visible stirring until;

(5) adding loess powder to the mixture after step (4) and stirring until loess powder is not seen;

(6) After heating the mixture after step (5) to 70 ℃, cooling to 40-50 ℃, maintaining the 40-50 ℃ temperature, pumice (pumice) and walnut powder powder is added to see the powder stirring until no more; and

(7) Pouring the mixture after step (6) into a soap mold and curing.

In one embodiment of the present invention, the soap base of step (1) is lauric acid, myristic acid, palmitic acid, stearic acid, sodium hydroxide (sodium hydroxide), glycerin, sorbitol, hyaluronic acid, and water may be included, and the content ratio of each component is lauric acid based on the soap base weight (100 wt%) 5-10 wt%, myristic acid 5-10 wt%, palmitic acid 5-10 wt%, stearic acid 10-15 wt%, sodium hydroxide 5-10 wt%, glycerin 15-25 wt%, sorbitol 10- 20 wt%, and 1-3 wt% of hyaluronic acid, and the balance may be water.

The exfoliating soap of the present invention can exhibit an excellent exfoliating effect including permis in which the molecular bonding structure is not changed by water, and unlike chemical artificial scrubs, there is no side effect by using natural materials, and contains hyaluronic acid, etc. This has the advantage of being able to remove dead skin cells without damaging the skin because there is no or little loss of moisture due to the surfactant. In addition, the soap manufacturing method of the present invention can provide a solid soap that is easy to remove dead skin cells because each component of the soap is uniformly aggregated within a short time without a chemical curing agent using loess and does not slide when used.

As a result of careful research on natural materials that can replace chemical exfoliants, the inventors of the present invention effectively remove dead skin cells without side effects when applying pumice used to clean rusty metal, toilet bowls, tiles, etc. to cosmetic soap. The present invention was completed by experimentally confirming that a soap additive and its formulation that can minimize skin moisture loss and skin irritation due to permis can be done.

Accordingly, the present inventors provide a soap for exfoliating a dead skin cell comprising a powder form of pumice.

The pumice contained in the exfoliating soap of the present invention is a kind of volcanic rock called pumice, pumice, or pumice, and has been used as a rusty abrasive because the particles form a porous, sponge-like structure.

On the other hand, the skin consists of the epidermis, dermis, and subcutaneous tissue, and the epidermis, which is the outer layer of the skin, is the stratum corneum, stratum lucidum, stratum granulosum, and stratum corneum. It is divided into (stratum spinosum) and stratum basale, acting as a protective barrier of the body against the external environment. The stratum corneum of the epidermis functions as a physical barrier to protect the skin from the external environment, but an excessive stratum corneum blocks the path through which skin wastes are discharged to the outside, causing skin troubles such as acne. Although the removal of dead skin cells can prevent such skin troubles, there is a problem that excessive removal of dead skin cells also damages the epidermis inside the stratum corneum, causing inflammation and weakening of the physical barrier protecting the skin.

Permis is a rock powder, and when it is contained in a large amount in soap, the exfoliating effect can be increased, but it can give excessive physical stimulation to the skin. Accordingly, the present invention provides a soap for exfoliating with walnut shell powder to reduce skin irritation caused by appropriate exfoliating wax.

The walnut shell powder of the present invention has been used as an abrasive for a scrub as a result of drying the shell of a walnut tree fruit and pulverizing it.

The present inventors confirmed that when soap was prepared by mixing pumice and walnut shells in a weight ratio of 2:1.5, strong exfoliating effect was obtained without excessive physical stimulation by permis.

In the present invention, the particle size of the pumice and walnut shell powder contained in the soap is preferably 150 to 300 μm, and in the case of less than 150 μm, the number of repetitions of friction between the skin and the soap (or soap bubble) should be increased to remove dead skin cells. It is inconvenient to use in that it is inconvenient to use, and if it exceeds 300 μm, it is deposited at the stage of solidifying the soap in the mold to take shape, or it is not evenly distributed on the soap base, so it is not saponified and excessive physical stimulation to the skin causes skin damage The downside is that you can. In addition, in the particles within the above range, the soap can be cured without breaking without the addition of a chemical curing agent, foam can be generated abundantly, and it can be used without being too soft even after contact with water.

On the other hand, exfoliation causes moisture loss in the skin regardless of the degree of exfoliation. Cells constituting the epidermis perform moisturizing and skin barrier functions by maintaining a certain amount of moisture. It may further include Western rapeseed oil (Brassica Napus Seed Oil), and the coconut oil and Western rapeseed oil may be included in 3 to 5 wt% based on the soap base.

The soap of the present invention for the cleansing ability of the soap and minimizing skin moisture loss is lauric acid, myristic acid, palmitic acid, stearic acid, sodium hydroxide ( sodium hydroxide), glycerin, sorbitol, hyaluronic acid, and water as a base, and each component of the soap base contains 5 to 10 wt% of lauric acid, 5 to myristic acid 10 wt%, palmitic acid 5-10 wt%, stearic acid 10-15 wt%, sodium hydroxide 5-10 wt%, glycerin 15-25 wt%, sorbitol 10-20 wt%, and hyaluronic acid 1-3 wt It can be %.

On the other hand, in the soap production method, in order to solidify the liquid soap during the saponification reaction, sodium hydroxide (NaOH) called caustic soda is generally added. It is essential to volatilize sodium hydroxide through drying for at least 4 weeks after induction of the saponification reaction. In the present invention, loess powder was used to minimize the use of sodium hydroxide in soap manufacturing to shorten the time required for the process and at the same time increase the moisturizing and exfoliating effects, in which case the soap was 2 parts by weight of the total soap (100). It may contain ~10 parts by weight of loess powder. When the loess powder is included in less than 2 parts by weight, the saponification reaction occurs slowly, and when it is included in more than 10 parts by weight, the hardness of the final soap is weakened and the soap is pushed during use.

In addition, the present invention can provide a foots-only exfoliating soap that additionally contains bee venom other than the above ingredients for improving athlete's foot. In particular, in the case of soap containing pumice, walnut shell powder, loess, and bee venom, it may be provided to patients with keratinous athlete's foot to improve symptoms of athlete's foot.

The present invention provides a method for preparing a soap for exfoliating dead skin cells, including the steps (1) to (7) below, in order to provide a soap having the best feeling of use, high cleaning power and exfoliating ability.
