Description

Soap comprising powder of water-dispersed activated carbon

The present invention relates to a water-inactivated carbon powder-containing soap containing activated carbon. More specifically, the present invention relates to a non-active carbon powder-containing soap formed by dispersing a non-activated carbon powder in a fat or oil which is a saponification raw material, unlike simply including activated carbon powder in a soap base.

Soap is the beginning of soap, when ancient Babylonians caught a goat, burned it, held a festival, and washed and washed it with the remaining ash. In Korea, red beans and mung bean powder are washed with water and foamed.

Recently, the main ingredients are high-quality fatty acids, sodium salts or potassium salts, mainly for cleaning the human body, and various additives for improving products, such as skin moisturizers, softeners, colorants, fragrances and deodorants, etc. Various soaps commercialized for various purposes, including cosmetic soaps containing medicinal ingredients, oxidative stabilizers, bubble stabilizers, etc., are known by the various manufacturers and can be purchased and used commercially. In particular, as it enters modern times, it is necessary to be able to protect skin with excellent cleansing power due to air pollution and the development of cosmetics, and to remove makeup and to solve heavy metal detoxification, sterilization, and moisturizing at once. Although it has been developed, but still have to use a variety of additives for heavy metal detoxification, sterilization, moisturizing, etc., these also have to be made of chemicals, which had a problem that acts as another irritant to the skin.

On the other hand, activated carbon is an aggregate of well-developed amorphous carbon made from wood, lignite, anthracite and palm bark, and is an adsorbent that has a large internal surface area because fine pores of a molecular size are formed well during activation. to be. The adsorbent may have a surface area of 1,000 mm 2 or more per g, and a functional group of carbon atoms present on the surface adsorbs molecules of the adsorbate by attracting the surrounding liquid or gas.

Therefore, activated carbon has been used in various fields such as filter, decolorization, deodorization, solvent recovery, and gas removal in various industries such as tobacco production, environment (air, water quality) and food industry. In order to use the properties of such activated carbon, charcoal soap or activated carbon soap in which activated carbon powder is simply dispersed in a soap base has been developed and commercialized. Currently, commercially available charcoal soaps or activated carbon soaps are produced by dispersing the activated carbon fine powder in the soap base as it is, so that the particle size of the activated carbon powder is uneven and the non-uniform dispersion due to the different physical properties between the activated carbon and the soap base. Due to such problems, there is a problem that can feel a foreign body when using the soap, the activated carbon is not evenly distributed throughout the soap, such as providing a high-quality soap.

An object of the present invention is to provide a water-inactivated carbon powder-containing soap containing activated carbon.

Another object of the present invention is to provide a water-inactivated carbon powder-containing soap in which activated carbon having an even particle size is homogeneously dispersed in the soap.

The non-active carbon powder-containing soap according to the present invention is made by dispersing 10 to 20% by weight of the non-active carbon powder of less than 20 µm in a fat or oil as a remaining amount of saponified raw material in a conventional saponification using oil or fat.

Hereinafter, the present invention will be described in detail with reference to specific examples.

The soap-containing activated carbon powder-containing soap according to the present invention is made by dispersing 10 to 20% by weight of the non-active carbon powder of less than 20 µm in a fat or oil as a remaining amount of saponified raw material in a conventional saponification using oil or fat. It is done.

In the above, the term "non-activated charcoal" means that the activated charcoal is pulverized and dispersed in water, and collected and dried in water without being submerged in water. The activated carbon powder itself, which usually has a size of 20 to 50 μm, has a large particle diameter and sinks when dispersed in water. Therefore, it is pulverized using a conventional pulverizer such as automatic induction or a ball miller, and the pulverization may be performed in the air, but may be pulverized in water using water as a dispersion medium. The activated carbon finely divided during grinding does not sink in water as a dispersion medium, but is floated and dispersed in water, which can be collected and dried to obtain a powder of non-active carbon. Therefore, repeating the milling of activated carbon can increase the yield of the non-active activated carbon. The particle size of the non-activated carbon does not exceed 20 µm at maximum. In defensive activated carbon, the term 'defense' means that when dispersed in water, it does not sink in water, but only takes floating. When the content of the non-active activated carbon is used in less than 10% by weight, the effect of containing activated carbon, that is, the far-infrared emission effect, sterilization effect, whitening effect by micro-exothermic reaction, heavy metal removal effect, detoxification effect and foreign substance removal effect due to activated carbon There may be a problem that the back is not enough, if it exceeds 20% by weight, rather than a significant increase in the effects due to the activated carbon, rather than causing a relative decrease in the content of the soap component, there is a problem such as cleaning effect and feeling of soap There may be.

The fat or oil may be selected from the group consisting of edible oil, palm oil, tallow, lard, or a mixture of two or more thereof, and all kinds of fats and oils that can be used as a raw material of soap may be used. It will be apparent to those skilled in the art that the present invention can be easily understood, and it will be understood that the present invention is not limited to the above-described oils and fats.

The present invention is characterized in that the non-active carbon powder having a very small particle diameter is sufficiently dispersed in a fat or oil as a raw material before saponification using a conventional kneader, and saponifying the fat or oil in a state where the non-active carbon is dispersed. Therefore, compared to the case where the activated carbon powder is directly dispersed in the semi-solidified soap body after saponification, after dispersing the hydrophobic activated carbon powder having a small particle size in the fat or oil which is a soap material, the saponified activated carbon powder is homogeneously dispersed throughout the entire soap body by saponification. It becomes possible.

The saponification of fats and oils as a soap material in the above can be carried out in the same or similar to the conventional saponification, it is natural for those skilled in the art that such saponification can be understood very easily. Saponification can be carried out with an alkaline solution such as sodium hydroxide or potassium hydroxide at a concentration of 5-10 M. The heating for saponification is also heated in a bath or the like to prevent the modification of the raw material, and the saponification time by stirring and heating at the time can also be understood to be well known to those skilled in the art. In addition, post-treatment such as salting, washing, flavoring and coloring and molding after saponification may be performed, and such post-treatment may also be understood to be easily performed by soap manufacturers and the like.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.

The following examples are intended to illustrate the invention and should not be understood as limiting the scope of the invention.

Example

Normal activated carbon having a particle diameter of 20 to 50 μm is finely divided into a ball mill commercialized with water as a dispersion medium, followed by fine collection of colloidal granular activated carbon dispersed in water, followed by drying to obtain a particle size of less than 20 μm. A non-activated carbon powder was prepared. The activated carbon submerged in water was repeatedly finely divided to increase the yield of the non-active carbon powder. 1.5 kg and 8.5 kg of palm oil powder thus obtained were mixed with each other using a conventional kneader to uniformly disperse the powder of non-activated carbon in the palm oil. Thereafter, 1.02 L of 7 M sodium hydroxide aqueous solution was added using palm oil having homogeneously dispersed non-activated carbon as a soap material, and saponified according to a conventional saponification method to obtain a soap base containing a non-activated carbon powder. The body was subjected to post-treatment such as salting out, washing with water, flavoring, coloring, and molding according to a conventional method to obtain a soap containing a non-activated carbon powder.
