Description

Composition for Colloid Detergent Using Plant Fatty Acid and Method Theirof}

1 shows a manufacturing process of the present invention.

The present invention relates to a colloidal detergent composition containing a vegetable fatty acid extracted from nature as a main component and a method for producing the same. More specifically, it is composed of vegetable fatty acid, lecithin, organic solvent, saponification agent, surfactant, emulsifier, and tocopherol to contain palm oil, soybean oil or rice bran oil at a constant ratio. In addition, a method of preparing a colloidal detergent composition containing vegetable fatty acids as a main component is to dissolve palm oil at 70 to 80 ° C., add soybean oil in a warm state, and then mix lecithin, and add an organic solvent and a saponifier to the fatty acids. After adding a surfactant and an emulsifier and stirring at high speed in a warmed state to prepare a uniform colloidal mixture, and adding tocopherol to the colloidal mixture, stirring at a high speed and further refine the colloidal particles and filtering the colloidal phase Prepare a detergent composition.

Detergents are classified into soap and synthetic detergents, and the detergent penetrates and adsorbs the surface of the contaminants to emulsify or disperse. The main component of the detergent is a surfactant, which has a characteristic of having a lipophilic group having a high affinity with oil and a hydrophilic group having a high affinity with water in the molecule, and thus plays an important role in decontamination. Surfactant used for detergent is contained 20-30% as anionic surfactant, and the remainder is mix | blended with preparation. Principle of cleaning removes contamination attached to the surface of the object and cleans it. The washing principle is to reduce the surface tension of detergent solution in one step. Is adsorbed. In two steps, the contamination is separated from the fiber surface. This transports contaminated particles separated by detergent dissolution, emulsification, and solubilization into the detergent solution. In three steps, the contaminant particles are stably dispersed into the detergent solution by the micelle to prevent redeposition on the fibers. Detergents are also adsorbed on the surface of the fiber to prevent re-adhesion on the surface or to reduce the contamination in the detergent solution by the high adsorption of the contamination on the surface of the foam. In addition, the mechanical force at the time of washing has the effect of easily dropping the contamination by stirring the contamination surface.

Soap is a typical anionic surfactant consisting of a long chain hydrophobic portion of a hydrocarbon and a hydrophilic portion of a carboxyl group combined with an alkali metal. Therefore, the aqueous solution lowers the surface tension of the water and the interfacial tension to perform a strong cleaning action with foaming power, emulsifying power and solubilizing power. On the other hand, soap has a disadvantage that it does not dissolve in water by making these ions and salts in hard water containing metal ions, and it has low solubility at low temperatures, while degrading by microorganisms and low foaming, so there is little environmental pollution. .

On the other hand, synthetic detergent used ABS (Sodium Alkylbenzene Sulfonate) as a raw material, but its biodegradability is bad because it causes environmental pollution is regulated. Biodegradable linear alkylbenzenesulfonate LAS (Linear Alkylbenzene Sulfonate), which is highly biodegradable, is made of linear alkylbenzene because it is less easily degraded by microorganisms (biodegradability) and remains in drainage, causing contamination. It is easy to use, good foaming, antifoaming agent, easy to control the foam and easy to clean, it is currently used in most synthetic detergents. Although it is more degradable than ABS, it is less biodegradable than soaps made with natural fats and oils, and it has strong lethal action on aquatic organisms such as foaming problems in the water, microorganisms, zooplankton, worms, and aquatic insects. There is a problem to reduce.

Brownian motion is a phenomenon in which colloidal particles having a diameter of about μm in a fluid (gas or liquid) and dispersion medium molecules in a solution collide with colloidal particles irregularly during molecular motion.

The present invention utilizes the principle that when lecithin is added to vegetable fatty acid, part of the molecular structure of the fatty acid is cleaved. In addition, when the surfactant and emulsifier are added to the fatty acid containing lecithin and rotated at high speed, the molecular structure is changed to a colloid of several micrometers in size. When the saponification agent and the additive is added and saponified, the detergent composition has a colloidal particle having a fine size in the emulsion by ultra-fast stirring. As the colloidal particles in the detergent composition are self-browning in the water during washing, they freely move freely without active physical force through active contact with the washing object. Therefore, the detergent composition causes contact, penetration, and collision with the dirt attached to the object to be cleaned by its own kinetic force, which removes the contaminants by the kinetic energy or falls together with the contaminants, thereby generating the washing power.

In the present invention, the soap in the conventional detergents, these ions and salts in the strong water containing metal ions do not dissolve in water, the low solubility at low temperatures, the poor detergency, synthetic detergents have low biodegradability, foam in water It is to solve problems such as strong aquatic life of aquatic organisms and reducing sewage treatment efficiency. In addition, in the prior art which uses vegetable fatty acid as raw material, palm oil has high carbon number of 14-18, high clouding point, low transparency of product, and high viscosity. It is difficult to handle because of high. Soybean oil has a low carbon number of 8-14, but the price of raw materials is high, which adds to the consumer burden.

The present invention has been completed by focusing on these problems of the prior art, and the problem of using palm oil by mixing palm oil and soybean oil is solved, and also by stirring at a high speed in the manufacturing process of the detergent composition, the colloidal particles are finely browned. It is to increase the cleaning effect by actively.

Conventional techniques related to the present invention include Korean Patent Publication No. 2003-35929 (active water-soluble natural detergent composition using soybean fatty acid and lecithin and its preparation method) to solve the problems of the conventional synthetic detergent, but using expensive soybean as a raw material. It has the disadvantage of economical efficiency and low cleaning effect. Korean Patent Publication No. 1987-418 (colloid detergent composition and its preparation method) is characterized in that the reaction at room temperature using higher alcohols, organic amines, active ingredients, additives to higher fatty acids. In addition, Korean patent application 1991-22494 (Method for preparing natural detergent for kitchen) consists of sulfate of ethoxylated vegetable fatty acid, sulfate of phytochemical fatty acid having 11-15 carbon atoms, diethanolamine salt of coconut fatty acid and amino acid derivative. It is characterized by prevention of contamination and reduction of skin irritation. Korean Patent Application No. 2003-74874 (natural detergent composition using rhizome roots, mulberry leaves, mulberry branches, cucumber leaves and goji berry leaves) is a mixture of each extract in the detergent composition. Korean Patent Laid-Open Publication No. 1998-25192 (liquid or gel detergent composition prepared from natural oils and fats) relates to a liquid or gel detergent composition mainly composed of castor oil and oleic acid. However, the prior art is different from the present invention and the technical configuration.

Palm oil, which is a fatty acid of the present invention, has a high cloud point and is opaque if the amount of use is high. In addition, there is a disadvantage in that a large amount of organic solvent is used more than necessary. Therefore, soybean oil or rice bran oil is used in combination with palm oil at a ratio of 1 to 2: 1 to save the economics of the raw material of palm oil, to compensate for the disadvantages of the properties of palm oil, and to increase the commerciality of the detergent composition. In addition, by colliding the particles finely by ultra-fast stirring to increase the washing effect by actively brown movement.

The colloidal detergent composition containing the vegetable fatty acid of the present invention as a main component is 15 to 30 parts by weight of vegetable fatty acid having a ratio of 1 to 2: 1 in palm oil, soybean oil or rice bran oil, 2 to 5 parts by weight of lecithin, and 10 to 10 organic solvents. It consists of 30 weight part, 8-15 weight part of saponifiers, 5-15 weight part of surfactants, 5-15 weight part of emulsifiers, and 2-10 weight part of tocopherols.

In addition, a method for preparing a colloidal detergent composition containing vegetable fatty acids as a main component is to dissolve palm oil at 70 to 80 ° C., to mix the soybean oil and lecithin in a warm state, and to add a surface active agent and an organic solvent and a saponifier to the fatty acid. And adding an emulsifier and stirring at high speed in a heated state to produce a uniform colloidal mixture, and adding tocopherol to the colloidal mixture and stirring at a high speed to further refine the colloidal particles and filter the colloidal detergent composition. Manufacture.

Among the vegetable fatty acids, palm oil contains about 45% of saturated fatty acid palmitic acid (C16: 0: Palmitic acid), and contains about 35% of unsaturated fatty acid oleic acid (C18: 1: Oleic acid) and about linoleic acid. It is about 10%. The fatty acid composition of palm oil has a ratio of saturated fatty acid and unsaturated fatty acid of about 1: 1, and the content of solid paper is narrow in the low temperature part and low in the high temperature part, as compared with Uji and pork fat. In addition, palm oil has better oxidation stability than other oils due to high saturated fatty acid content (about 50%) and low linoleic acid content (less than 10%). Compared to the time, palm oil shows extremely good stability around 60 hours. Palm oil is widely used in fried oil (fish paste, croquettes, instant noodles, snack foods) and processed fats (margarine, shortening, etc.).

Soybean oil (soybean oil) is a (semi) dry oil obtained by extracting a solvent from soybean seeds, also called soybean oil. The soybean oil content of seeds is 13-26%, which is used for edible oil, margarine, and paint. Iodine values range from 125 to 135, and the major component fatty acids are 50% linoleic acid and 25-30% oleic acid, 2-10% linolenic acid, 2-10% palmitic acid, and 2-5% stearic acid. It contains. Fats and oils containing fresh linoleic acid are effective in the prevention and treatment of plasma, but fats and oils containing polyunsaturated fatty acids are easily oxidized, and the resulting lipid peroxide is toxic. It must be restrained.

The fatty acid of the present invention is preferably palm oil, soybean oil or rice bran oil in a ratio of 1-2: 1. In terms of manufacturing cost, it is better to use a lot of palm oil, but palm oil has a disadvantage of degrading its merchandise due to its high cloud point and opacity. In addition, palm oil has a disadvantage in that a large amount of organic solvent, an emulsifier, and a surfactant need to be used unnecessarily. Therefore, soybean oil or rice bran oil may be used together to compensate for the disadvantages of palm oil and to increase the commerciality.

Lecithin is typically abundant in phospholipids, and is widely distributed in living organisms such as animals, plants, and microorganisms, and is present in the brain, soy sauce, egg yolk, soybean, and yeast. Since lecithin has colloidal, surface activity, emulsifying, softening, detergency, and antioxidant properties, it is used for food (margarine, chocolate, confectionery, ice cream, dairy products, bakery, noodle), medicine (vitamin, bone formation, cosmetics). It is widely used for industrial purposes (ink, leather, textile). Since lecithin has surfactant and emulsification property, it is preferable to add lecithin at the beginning of the reaction.

The organic solvent is used to prevent the solidification of palm oil, but it is good to reduce the amount of use as much as possible, but it is essential to ensure smooth flow and fluidity of the composition. As representative organic solvents, any one or more of butylene glycol, polyethylene glycol-based, propylene glycol, isopropyl alcohol, and stearyl alcohol may be selected.

Nonionic surfactants are co-surfactants that promote condensation reactions with fatty acids and function as nonionic surfactants. Typical nonionic surfactants are ethylene oxide, isooctylphenoxy polyoxyethoxyethanol, and p-tert-oxyphenoxy poly. Either one or more of ethoxyethanol and polyhydric alcohol can be used.

Emulsifiers act to emulsify fatty acids and surfactants, and also to accelerate the saponification reaction and to shorten the reaction time. As the emulsifier, any one or more of alkanolamide and triglyceride may be used.

The saponifier serves to promote the saponification reaction and to control the saponification reaction of fatty acids, and any one or more of trolamine, sodium triphosphate, caustic soda and sodium borate may be used.

Tocopherol is one of vitamin E which is high in vegetable oil and is not soluble in water and not toxic. It is weak to heat, so it is not preferable to add it at high temperature. . Tocopherols are high in vegetable oils and are insoluble in water and nontoxic. Tocopherol acts as an antioxidant that inhibits the production of free radicals and lipid peroxide by scavenging free radicals in vivo. In old age, the cell's regenerative power is declining, and hepatocytes and nerve cells are healthy and metabolism is active. In addition, tocopherol has the ability to enhance immune function and increases the production of white blood cells, so lipofucin is expressed in the cells of the body, and unsaturated fatty acids in vivo cause peroxidation polymerization and react with blood or muscle protein. It also plays a role in preventing bioaging. In addition, it has a physiological effect function that revives and strengthens fertility, and also prevents and kills the spread of cancer cells, and loses physiological activity of cell membranes and biological membranes due to the production of free radicals and peroxides caused by illegal oxidation. Inhibition of cell function and necrosis, etc. have the effect of inhibiting aging, so in place of the preservatives can be used to remove the side effects of preservatives in addition to the above effects.

In addition, palm oil, which is a raw material of the detergent composition of the present invention, has 14 to 18 carbon atoms and has a relatively high molecular weight and a high cloud point, so that an organic solvent may be used to ensure flowability and fluidity. However, when the amount of the organic solvent used is large, it becomes a flammable or explosive substance, which makes it difficult to handle the product and increases the manufacturing cost. Fatty acid is used 15 to 30 parts by weight as a whole, palm oil is 10 to 20 parts by weight of palm oil in the range of 1-2 times compared to soybean oil or rice bran oil and heated to 70 to 80 ℃, soybean oil or rice bran oil 5 to 10 A mixture of 2 parts by weight to 2 parts by weight of lecithin, 10 to 30 parts by weight of organic solvent, 8 to 15 parts by weight of saponifier, 5 to 15 parts by weight of surfactant, and 5 to 15 parts by weight of emulsifier are added to the fatty acid. Stirring at 3,000 to 4,000 rpm at high speed at -50 ° C to form a uniform colloidal phase, and adding 2 to 10 parts by weight of tocopherol to the colloidal mixture and ultrafast stirring at 40 to 50 ° C at 4,000 to 5,000 rpm to further refine the colloidal particles. To prepare a detergent composition comprising the step of.

The organic solvents, saponifiers, surfactants, and emulsifiers are merely exemplary, and it can be seen that the compound can be used in various ways by those having similar functions by those skilled in the art. have.
