Description

SOLID DETERGENT

The present invention relates to a solid detergent with less skin irritation and superior antimicrobial and radioactive contaminant removal performance.

Surfactants are hydrophobic and hydrophilic, which can significantly reduce the interfacial tension of liquids, and are essential to make soaps, synthetic detergents, or cosmetics that mix well with and dissolve in both oil and water. Surfactants include natural surfactants and synthetic surfactants. Synthetic surfactants have the advantage of low cost and strong cleaning power, and synthetic surfactants are mostly used in daily life.

However, synthetic surfactants have a strong detergency which weakens not only contaminants but also skin lipids, thereby impairing skin barrier function. Therefore, it is easy for foreign substances to penetrate into the skin, moisture in the skin is easily evaporated, the skin quickly becomes dry, wrinkles can be formed, and the aging can proceed rapidly.

In addition, it has been pointed out as a causative substance causing all kinds of skin allergies and dermatitis. Builders, preservatives, artificial fragrances and the like added to improve the function of a detergent made of a synthetic surfactant are not proved to be stable, It is easy to be exposed. In other words, products containing synthetic surfactants are focused on the function of removing pollutants, and skin health and environmental protection aspects are not considered at all.

In order to overcome the disadvantages of the synthetic surfactant, recently, products containing natural surfactants have been demanded, and natural soaps have been attracting attention. Natural soap is generally used as vegetable oil as a main ingredient, and is excellent in moisturizing effect and more environment-friendly than general soap. However, the natural soap is difficult to mass-produce, and the price is high. Since the hand soap is hand made by the whole process, the shelf life is shorter than that of general soap, and it is disadvantageous in that it is not easily worn.

In addition, kitchen detergents are generally used in liquid form, and liquid type kitchen detergents are not easy to carry and store because of their large weight and weight. In addition, since the kitchen detergent directly touches the skin of the user during use, the detergent may remain on the skin after use and cause skin diseases. If the detergent remains in the tableware, such detergent ingredients may be directly administered to the user's oral cavity, .

Accordingly, although a solid type kitchen detergent has been developed, in the case of a solid type, since it is exposed to the external environment until it is consumed after its use, the propagation of germs may be facilitated and sanitary control may be difficult. Also, as the size of the solid type kitchen detergent is reduced according to use, the user may feel inconvenience in bubbling.

On the other hand, as industry has developed, the risk of exposure to radioactive pollutants, not general pollutants, has increased. Particularly, it is difficult to completely remove the radioactive contaminants such as cesium and strontium by the general detergent composition alone. If the radioactive contaminants are absorbed into the body, it may lead to birth defects such as thyroid cancer and leukemia, It can also influence later generations.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a solid detergent with less skin irritation and excellent antibacterial and radioactive contaminant removal performance.

An aspect of the present invention provides a solid detergent comprising glycerin, zeolite, bentonite, and chlorella as active ingredients, wherein the zeolite content is 5-15 wt% based on the total weight of the solid detergent.

In one embodiment, the content of bentonite may be 5 to 10 wt% based on the total weight of the solid detergent.

In one embodiment, the content of chlorella may be 3 to 10% by weight based on the total weight of the solid detergent.

In one embodiment, the solid detergent may further comprise 10 to 20 wt% of sodium bicarbonate, 10 to 20 wt% of sodium sesquicarbonate, and a remaining amount of soap powder.

In one embodiment, the soap powder may comprise palm oil and coconut oil at a weight ratio of 50 to 70: 30 to 50, respectively.

In one embodiment, the average particle size of the soap powder may be between 500 μm and 1,000 μm.

In one embodiment, the water content of the soap powder may be 1 to 7 wt%.

In one embodiment, the pH of the soap powder may be at least 10.

In one embodiment, the porosity of the zeolite may be between 15 and 30% by volume.

The zeolite, bentonite, and chlorella contained in the solid detergent according to one embodiment of the present invention are excellent in adsorption, removal performance and antibacterial property of cesium which is a typical radioactive contaminant.

In addition, bentonite, chlorella, and glycerin contained in the solid detergent can significantly reduce skin irritation.

It should be understood that the effects of the present invention are not limited to the effects described above, but include all effects that can be deduced from the description of the invention or the composition of the invention set forth in the claims.

Hereinafter, the present invention will be described in detail. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Also, throughout the specification, when an element is referred to as "including" an element, it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

One aspect of the present invention provides a solid detergent comprising glycerin, zeolite, bentonite, and chlorella as an active ingredient.

The solid detergent may comprise from 5 to 10% by weight of glycerin. Glycerin is a colorless, odorless and non-toxic representative moisturizing raw material, and is well soluble in water and alcohol, and thus has excellent water absorption ability. Particularly, it has excellent moisture fixing ability and can keep the skin smooth, and it is possible to prevent harmful substances from entering the skin from the outside. In addition, moisture in the air can be absorbed to maintain moisture on the surface of the skin, thereby preventing the skin from drying out.

The solid detergent may comprise from 5 to 15% by weight of zeolite. The zeolite is a kind of feldspar mineral which is composed of silicon (Si) and aluminum (Al) and is a porous material containing nano-sized pores therein. The zeolite has a high ion exchange capacity and can convert hard water to soft water.

The term " hard water " and " soft water " used in this specification refer to the amount of calcium and magnesium contained in water, respectively. Generally, water having a hardness of 90 mg / L or less is called soft water, and water having a hardness of 200 mg / L or less is called hard water.

When cleaning is carried out on the hard water, the components such as calcium and magnesium are combined with the soap powder to generate a sediment, thereby lowering foaming and deteriorating the cleaning power. Therefore, when cleaning an object to be cleaned in the same amount, a larger amount of cleaning agent is required, and the efficiency may be lowered. The zeolite is excellent in the ability to exchange calcium ions in the hard water phase, so that the hard water can be replaced with the soft water and finally the washing power of the cleaning agent can be improved.

In addition, the zeolite is not only excellent in ion exchange ability of a substance such as calcium, but can effectively adsorb and remove radioactive contaminants such as cesium, strontium and the like. If the content of zeolite is less than 5% by weight, the detergency and the effect of adsorbing radioactive contaminants may be deteriorated. If the content is more than 15% by weight, zeolite may remain on the object to be cleaned after washing, adversely affecting the user's health.

The porosity of the zeolite may be from 15 to 30% by volume. If the porosity is less than 15% by volume, the adsorbing effect of the radioactive contaminants and the washing power may be deteriorated. If it exceeds 30% by volume, the durability of the solid detergent may be deteriorated.

The solid detergent may comprise from 5 to 10% by weight of bentonite. The bentonite is a viscous minerals, and has a crystal structure of 2: 1 in the form of a Si-tetrahedron layer and an Al-8 octahedron layer. High viscosity, wide specific surface area, swelling property, adsorption property and ion exchange property. Particularly, since it has a large specific surface area and a high ion exchange capacity, it is possible to adsorb and remove contaminants to be cleaned, in particular, radioactive contaminants during cleaning.

In addition, the bentonite can bond with a holding component of a soap powder to be described later to form a protective film on the skin surface. When the bentonite is absorbed into the skin, it absorbs moisture to supply and maintain moisture to the skin, and the minerals contained in the bentonite can be exchanged with the noble material to remove the noble material and simultaneously supply the minerals. If the content of bentonite is less than 5 wt%, the adsorption of radioactive contaminants and the skin protection effect may be deteriorated. If the content of bentonite is more than 10 wt%, the detergency of the detergent may be deteriorated.

The solid detergent may comprise 3 to 10% by weight of chlorella. The chlorella belong to the green algae that grow in fresh water and are spherical or elliptical single cell organisms having a diameter of 10 탆 or less. It is a kind of plankton, rich in protein, chlorophyll, vitamins, minerals, amino acids, and other nutrients. It has been studied by NASA for astronaut food.

The chlorella has no flagellum and no motility, and the cell has one nucleus and one cup-shaped chloroplast. Growing cells proliferate through cell division, and usually four daughter cells form endospores (endospores).

The chlorella can adsorb and remove radioactive contaminants together with the bentonite and zeolite. Specifically, the bentonite and zeolite remove radioactive contaminants by a chemical method, i.e., adsorption, and the chlorella can block and discharge radioactive contaminants in a biological manner. That is, the chlorella can prevent deterioration of intrinsic detergency of the detergent when excess bentonite and zeolite are used, and can maximize the removal performance of the radioactive contaminants by complementing their chemical removal performance in a biological manner. In addition, since chlorella contains various vitamins, the skin protection effect can be realized during washing.

The solid detergent may further comprise 10 to 20% by weight of sodium hydrogencarbonate, 10 to 20% by weight of sodium sesquicarbonate, and a remaining amount of soap powder.

The solid detergent may comprise sodium bicarbonate and sodium sesquicarbonate, and the content thereof may be 10 to 20% by weight, respectively. Wherein the sodium hydrogencarbonate is a hydrogencarbonate and the sodium sesquicarbonate is a hydrogencarbonate.

The sodium hydrogencarbonate and sodium sesquicarbonate are made alkaline and added to the solid detergent to supplement the alkali, prevent contamination of the object to be cleaned, and improve the cleaning effect together with the surfactant.

The content of the sodium hydrogencarbonate and the sodium sesquicarbonate may be 10 to 20 wt%, respectively. If the content is less than 10 wt%, the detergency may be deteriorated. If the content is more than 20 wt%, the skin of the user may be damaged.

The solid detergent may be prepared by subjecting a soap powder to a subject, and the soap powder may be formed through a saponification process. Generally, the saponification process can be prepared by neutralizing the fatty acid of an acidic oil with an alkali such as sodium hydroxide or potassium hydroxide.

The fat may be an animal oil or a vegetable oil, but because the vegetable oil is less irritating to the skin than the animal oil, preferably the fat can be a vegetable oil, more preferably one of palm oil and coconut oil Or more.

The palm oil is a vegetable oil extracted from flesh of palm kernel fruit. Since palm oil is a vegetable oil, it is similar to animal oil because it is composed of saturated fatty acid and unsaturated fatty acid in a ratio of about 1: 1, and it increases absorption power to skin and contains oleic acid which is an unsaturated fatty acid, The saponification reaction can be effectively promoted.

The coconut oil is a vegetable oil extracted from coconut fruit and is a representative oil used in making natural soap together with olive oil and palm oil. As with palm oil, it contains saturated fatty acid, which facilitates the saponification reaction, increases the hardness of the detergent, prevents rancidity, and produces a rich foam.

The soap powder may be a mixture of palm oil and coconut oil at a weight ratio of 50 to 70:30 to 50, respectively. If the weight ratio of the palm oil and the coconut oil is out of the above range, the moisturizing power against the skin may be lowered or the washing power may be lowered, and the detergent may be easily retracted. The higher the content of palm oil, the higher the transparency of the prepared cleaning agent, and the lower the transparency of the prepared solid as the content of coconut oil is higher. Therefore, the mixing ratio of the palm oil and the coconut oil can be appropriately adjusted according to the transparency to be produced.

The average particle size of the soap powder may be 500 탆 to 1,000 탆. If the average particle size of the soap powder is less than 500 탆, the surface area may become large and the viscosity may become excessively high. If the average particle size is more than 1,000 탆, kneading with other components may be difficult in a subsequent process.

The water content of the soap powder may be 1 to 7% by weight. If the water content of the soap powder is less than 1 wt%, the soap powder can be easily broken, and if it is more than 7 wt%, the soap powder can be easily retooled.

As used herein, the term " moisture content " is a percentage of the weight of water relative to the total weight of a particular material containing moisture. For example, the water content of a soap powder containing water means the percentage of the weight of water relative to the total weight of the soap powder.

The pH of the soap powder may be 10 or more. Generally, soaps include acid soaps and alkaline soaps. Acidic soap does not damage the skin and is effective for skin moisturization. Specifically, human skin is covered with a weak acidic pH of pH 4.5-5.5 to protect the skin surface. Therefore, although acid soap is more effective in terms of skin protection than alkaline soap, unlike alkaline soap, antibacterial property and detergency can be lowered due to low foaming power.

Therefore, the pH of the soap powder can be adjusted to 10 or more to improve the antibacterial property, and the detergent and the skin protection performance can be realized at the same time including the substance having excellent skin protection effect.

The solid detergent may further comprise plant essence oil, if necessary. The vegetable essence oil is a liquid concentrated and extracted from stem, leaf flower, root, etc. from the plant. Since the plant essence oil is added to the solid detergent to diffuse the aroma and the effect varies depending on the kind, the aroma and effect The plant essence oil can be appropriately selected according to the type of the plant essence oil.

The plant essential oil may be selected from the group consisting of Eucalyptus, Peppermint, Lemongrass, Palmarosa, Lavender, Chamomile, tea tree and mixtures of two or more thereof Lt; / RTI > group, but is not limited thereto.

The solid detergent may be manufactured in a solid type, and the length and width of the solid detergent may be individually adjusted to a range of 0.5 to 3 cm. The solid detergent adjusted to the above range can contain a necessary amount for three to four times of cleaning, and is convenient to carry and store, and can be sanitarily managed with less exposure time to the outside. The shape of the solid detergent may be, for example, circular, elliptical, square, tablet, and the like, but is not limited thereto.

Also, the individual package is formed of a safety cap including an inner cap and an outer cap, and can be easily opened by a certain external force, but is not easily opened by the power of infants and children.

Hereinafter, embodiments of the present invention will be described in detail.
