Pollution-free detergent composition {Composition of non-hazardous detergent}

The present invention relates to a detergent composition, and more particularly, to a pollution-free detergent having excellent detergency and deodorizing properties while maintaining a stable harmlessness to a human body and having a very high biodegradability, thereby minimizing the ecological impact on the environment. To a composition.

Synthetic detergent may be classified into washing, kitchen, and bath depending on the use. In particular, laundry detergent is subdivided into alkaline, acidic and neutral depending on ingredients. Alkaline detergents, which make up the mainstream of household detergents, have excellent washing power. The higher the acidity, the higher the washing power, but the higher the risk of desalination. Acid detergents are highly acidic, so when used for washing, there is a risk of reducing the flexibility of the fiber is mainly used as kitchen detergents, rinse. Neutral detergents, such as high alcohol detergents and leather detergents, are expensive, but can be used relatively safely in all garments.

Since these synthetic detergents inevitably use petrochemical by-products as surfactants, they are not only toxic in themselves, but they are also the main cause of water pollution because they are only 60% biodegradable after 6-7 days in water. . Toxicity of synthetic detergents are harmful to the human body, such as causing skin inflammation, eczema, skin roughness, hair loss, and so there is a problem of causing inconvenience and anxiety to detergent users.

In particular, various detergents developed in the past focus on improving the harmful effects on the skin, but the anionic surfactants contained in this case may cause eutrophication, thereby adding to the severity of environmental pollution.

Accordingly, an object of the present invention is to provide a pollution-free detergent composition which has an excellent detergency and deodorizing properties while maintaining a stable harmlessness to a human body and having a very high biodegradability, thereby minimizing the ecological impact on the environment. do.

In order to achieve the above object, the present invention provides a surfactant group consisting of linear alkylbenzene sulfonate (LAS), alpha olefin sulfonate (AOS), sodium laurate sulfate (SLES), and an emulsifier, soda ash, caustic soda, urea and perfume. After mixing the auxiliary material group consisting of, and a predetermined additive group is formed by stirring.

As one aspect of the present invention, the additive group is used for washing 20 to 22wt%, AOS 50 to 54wt%, SLES 3 to 5wt%, soda ash 4 to 6wt%, emulsifier 3 to 5wt%, caustic soda 1 ~ 2wt %, 0.5 to 1.5 wt% of urea, 3 to 5 wt% of tripolyurethane, 3 to 5 wt% of sodium metasilicate, 0.5 to 1.5 wt% of antistatic agent, 0.5 to 0.7 wt% of hexametaphosphate, gluconic acid Mix 0.5 to 0.7 wt%.

As another aspect of the present invention, the additive group is LAS 36 ~ 38wt%, AOS 15 ~ 17wt%, SLES 10 ~ 11wt%, soda ash 1 ~ 2wt%, emulsifier 3 ~ 5wt%, caustic soda 1 ~ 2wt %, 2 to 3 wt% urea, 7 to 9 wt% ammonium chloride, 15 to 17 wt% TEA (Tri Ethyl Amine), and 0.8 to 1.4 t% CDE (Cocamide Dimethyl Ethanol).

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

Detergent of the present invention is a linear alkyl benzene sulfonate (LAS), alpha olefin sulfonate (AOS), sodium laures sulfate (SLES), a surfactant group consisting of emulsifiers, a soda ash, caustic soda, urea, fragrance group After mixing a predetermined group of additives, characterized in that it is formed by stirring until the purple color.

Surfactants have various functions such as wetting, penetrating, foaming, antifoaming, solubilizing, dispersing, emulsifying, cleaning, antistatic, and sterilization. In general, surfactants are cationic, anionic, amphoteric, and nonionic interfaces depending on the ionic properties dissociated in water. Classify as active agent. Zwitterionic surfactants are safer for the skin than other ionic surfactants and have superior cleaning, bactericidal and softening effects. However, in any case, as described above, since it can be a cause of water pollution and skin diseases, the present invention achieves the problem of eliminating this problem by the selection of the appropriate auxiliary and additive groups.

LAS (Linear Alkylbenzene Sulphonates) is a petrochemical anionic surfactant synthesized from alkyl benzene and has excellent foaming and the foam is easily stabilized by stabilizers. Very sensitive to the strength of water, the washing power is significantly reduced as the strength increases. Typically, the biodegradability of LAS is about 98%, but has a disadvantage in that the biodegradability is lowered under anaerobic conditions. However, this is complemented by the action with other components proposed in the present invention.

A.O.S. (α-Olefin Sulfonate) is a petrochemical anionic surfactant synthesized from alpha (α) olefin, which is environmentally friendly and gentle to the skin, making it suitable as a main ingredient in soft detergents. AOS's excellent detergency is not so low in hard water, and its high biodegradability is appropriate in terms of environmental protection. In some cases, it is recognized as an alternative to LAS.

Sodium Laureth Sulfate (SLES) is a relatively strong surfactant synthesized from lauric acid in vegetable oils and is water soluble and usually has a pH in the range of 6.0-7.0 (3% aqueous 25 ° C.). It is used for shampoos by making bubbles well in hard and sweet water. In the present invention, such SLES uses the product name MICOLIN ES-430 of Miwon Corporation.

The emulsifier is the chemical name Nonylphenol 8mole ethoxylates, commonly referred to as emulsifying agent, and is a surfactant that has both a hydrophilic group and a lipophilic group in one molecule. It has good spreadability in the range of 30-35 dynes / cm to form a stable mixture (emulsion) between water and oil. It can also be used as a water-soluble cleaner suitable for replacing harmful solvents. In the present invention, the above emulsifier uses the product name NP-8 of Miwon Corporation.

Soda ash (light) is sodium carbonate (Na ₂ CO ₃ ) as white hygroscopic powder or mass and its aqueous solution is slightly alkaline. The former is used in industrial sodium carbonate (soda soda) and electronic industry sodium bicarbonate (soda soda). It is also used as melting point lowering agent and alkali ingredient supply in glass industry, fatty acid neutralizer, and mixing agent to improve washing function in tax service industry.

Sodium Hydroxide (NaOH) belongs to alkali metal salts such as soda ash. White translucent deliquescent solid, soluble in water, exothermic, fast reaction and strong corrosive. In addition, bleaching and precise pH adjustment are possible, and the reaction products are often soluble. It is used as a raw material for the manufacture of honeycomb, paper, pulp, soap, synthetic fiber, etc., and requires more than 98% purity in detergent applications.

The chemical formula of urea (industrial) is CO (NH ₂ ) ₂ , a colorless (or white), columnar crystal with an ammonia odor. Industrial urea is used in the manufacture of adhesives, resins, paints, feed, synthetic detergents, wastewater treatment, dyes and the like. It is soluble in water and alcohol, but insoluble in ether.

The fragrance uses synthetic synthetic fragrances, which are industrially mass-produced and inexpensive. It uses compounds that are readily available from natural or petrochemical and other resources as starting materials. This invention uses the lilac fragrance which has phenyl acetaldehyde (aldehydes) as a main component.

At this time, the additive group according to one aspect of the present invention mixes tripoly, sodium metasilicate, antistatic agent, hexametaphosphate, gluconic acid to the surfactant group and auxiliary material group to utilize for washing.

Tripoly (Na ₅ P ₃ O ₁₀ ), also called sodium polyphosphate, sodium phosphate, pentasodium tripolyphosphate, and tripolyphosphate, is a white crystalline powder detergent builder that helps complex the ions that cause water hardness. . In addition to synthetic detergents, it is also used as a cleaning agent, metal ion sequestrant, and cleaning agent. Soluble in water, insoluble in alcohol, aqueous solution alkaline and absorbent. Not only is it excellent in pH buffering capacity, but also has very strong binding ability with metal ions.

Sodium metasilicate (NaOnSiO ₂ ㆍ 2H ₂ O) is also called sodium metasilicate (Sodium Meta Silicate) and generally has a molecular formula of Na ₂ O-nSiO ₂ -xH ₂ O. Due to its strong detergency and excellent emulsion dispersibility, it is used as a soap compound, hardener, adhesive, detergent, and waterproof agent. The pH of the aqueous solution is stronger than that of the general alkali solution, and the pH is little changed depending on the concentration, and has a buffer function to adjust the alkalinity. In the use of synthetic detergents, the dispersibility and adsorptivity due to the action of hydrophilic silicic acid are excellent, so that the washing power can be enhanced.

The antistatic agent mainly forms a polymer network structure on the fiber surface by crosslinking as a compound having an ionic or hygroscopic functional group. When a continuous film is formed such that the lipophilic group is inward and the hydrophilic group is outward, moisture in the air is adsorbed to the hydrophilic group to exhibit an antistatic effect. The low molecular weight antistatic agent is preferred because the antistatic agent is severely separated due to the increase in the number of washing, the frictional voltage of the fabric is increased.

Sodium hexametaphosphate [(NaPO ₃ ) ₆ ] is colorless or white glassy, soluble in water but insoluble in alcohol and aqueous solution is alkaline. It has a high water absorption, and has excellent properties such as metal ion blocking, pH buffering, washing and dispersing.

Gluconic acid (C ₆ H ₁₂ O ₇ ) is a colorless or pale yellow liquid that has strong anti-rust properties for iron products. In particular, it is sour and harmless to the human body, so it can be used as an additive to liquor, vinegar, and soft drinks, which is the most suitable ingredient for washing food containers.

At this time, the additive group is used for washing LAS 20 ~ 22wt%, AOS 50 ~ 54wt%, SLES 3 ~ 5wt%, soda ash 4 ~ 6wt%, emulsifier 3 ~ 5wt%, caustic soda 1 ~ 2wt%, urea 0.5 ~ 1.5wt%, 3 ~ 5wt% Tripoli, 3 ~ 5wt% Sodium Metasilicate, 0.5 ~ 1.5wt% Antistatic Agent, 0.5 ~ 0.7wt% Sodium Methaphosphate, 0.5 ~ 0.7wt Gluconic Acid Mix%. Appropriate content ranges and the place of purchase of each component are shown in Table 1.

In various experiments, when the above-mentioned content is reached, the finished detergent is expressed as a viscous liquid and purple (colored). This is not due to the addition of any dyes, but is entirely due to chemical reactions, so the laundry does not discolor under the influence of pigments. According to the test report of Korean Chemical Testing Institute (Accession No. TAP-000952), hazardous ingredients such as As and Pb are not included. According to the Technical Report (Test No. 90-68), the biodegradability is 98.1%, the pH is 10.4, and the surface tension is 28mN / m.

In addition, according to another aspect of the present invention, the additive group is mixed with ammonium chloride, Tri Ethyl Amine (TEA), and Cocamide Dimethyl Ethanol (TEE) in the surfactant group and the auxiliary material group to utilize for kitchen use. In such a kitchen detergent, the surfactant group and the auxiliary material group are the same as the laundry detergent described above.

Ammonium chloride (NH ₄ Cl) is a colorless, odorless crystalline powder, usually a cationic surfactant, used as a raw material for analytical reagents, pharmaceuticals, and fertilizers. Na ⁺ or K ⁺ is a hydrophilic group with a negative charge, but cannot bind to the minority moiety, while NH4 ⁺ can bind to the minority even if it is a cation. Soluble in water, glycerol, alcohol, etc., unlike caustic soda, it is decomposed by endotherm.

T.E.A (Tri Ethyl Amine) is an alkaline softener and is generally used as an intermediate raw material for fine chemical products. It is divided into MONO, DI, and TRI according to the type. In particular, fatty acid soaps of TEA are used as fiber treatment agents. Due to the physical properties that react with acids to produce ester amides and salts, they are used in a wide range of applications such as various detergents, textile treatment agents, cement additives, basic raw materials and additives for various surfactants. Domestic salesmen use products from Miwon Trading Co., Ltd. and Mitsui Chem.

The fragrance of the kitchen detergent may be the same as the laundry detergent, but it is better to select the quince flavor so that it can be easily distinguished in production and use. Perfume may be added at the end of the process instead of mixing with other ingredients simultaneously.

At this time, the additive group is used for kitchen LAS 36 ~ 38wt%, AOS 15 ~ 17wt%, SLES 10 ~ 11wt%, soda ash 1 ~ 2wt%, emulsifier 3 ~ 5wt%, caustic soda 1 ~ 2wt%, urea 2 ~ 3 wt%, 7-9 wt% ammonium chloride, 15-17 wt% of TEA (Tri Ethyl Amine), 0.8-1.4t% of CDE (Cocamide Dimethyl Ethanol) are mixed with respect to 3 wt% and 1-2 wt% of fragrance. In the case where the above content is satisfied, the detergent is generally expressed in purple (color), which is the same as the laundry detergent described above.

Biodegradation is a general term for describing the cumulative result of many small biotransformation steps. Most chemicals lose their original properties and try to change over time, but especially when organisms are involved, metabolism can quickly convert contaminants into other compounds. In the case of synthetic detergents, the farther the ends of the hydrophilic group and the hydrophobic group, the easier the decomposition by the microorganism. In the present invention, the main component of the surfactant is biodegradation in the reaction in which the terminal methyl group of the lipophilic group (alkyl group) is oxidized and changed to a carboxyl group, and thus the washing / kitchen synthetic detergent of the present invention is chemically changed. In the process, the compound loses most of its original toxicity and is therefore considered harmless to the ecosystem and safe for the human body.

As the additive group according to the present invention, it is also possible to additionally use a silicone oil which is a raw material for producing a surfactant.

On the other hand, biosurfactant such as Sopolori lipid is considered as the next generation surfactant because biodegradability is superior to synthetic detergents. However, productivity is low and the cost burden is high, so it is difficult to expect active use of real life.

According to the above configuration and action, the present invention has an effect of minimizing the ecological impact on the environment because it has an excellent detergency and deodorizing properties and maintains stable harmlessness to the human body and has a very high biodegradability.
