Description

Detergent composition

The present invention relates to a composition, and more particularly to a detergent composition suitable for removing dirt, dirt and the like.

Generally, synthetic detergents of cationic and nonionic surfactants are generally used, for example, formaldehyde, a fluorescent agent, benzene, ethylene diamine tetraacetate (EDTA), phosphate, etc. Compounds, to achieve the purpose of removing dirt and grease. Among them, the nonionic surfactant containing nonylphenol, because the chemical structure is similar to the estrogen structure of animals, is also called environmental hormone, which can interfere with the regulation mechanism of secreted hormones in the body, and At very low concentrations, the effects of natural hormones can be simulated, directly stimulating or inhibiting the endocrine system of the organism, thereby impeding reproductive and developmental functions, thus having a major impact on the health and reproduction of the organism.

In addition, cationic and nonionic surfactants do not meet international environmental protection standards in terms of biodegradability, while synthetic detergents are incompletely used for surfactants, which usually only transfer dirt, grease, and oil to water. When detergents and sewage are discharged into the environment, the dirt still exists. This not only causes secondary pollution of the environment, but also pollutes the water source. Such a continuous vicious cycle will also cause serious damage to the ecological environment. Obviously, synthetic detergents provide some convenience in life, but they cause high pollution to the environment and ecology.

It is an object of the present invention to provide a detergent composition which is environmentally friendly and which has a better cleaning effect.

The detergent composition of the present invention comprises: 11 to 45 parts by weight of a natural surfactant; 25 to 35 parts by weight of Glauber's salt; 10 to 40 parts by weight of sodium carbonate; 0.1 to 5 parts by weight of methylglycine diacetate a trisodium salt; and a total of 100 parts by weight of a cleaning aid together with the aforementioned components.

The natural surfactant of the present invention is selected from the group consisting of: cocoanut oil, coconut powder, hydrogenated castor oil, and palm oil, wherein the coconut oil has the effects of mild texture, bacteriostasis and skin protection. The above-mentioned natural surfactant has better permeation effect, can completely destroy the molecular structure of dirt, oil and grease, and achieve the effect that the wastewater discharge process can be completely decomposed by microorganisms.

The Glauber's salt used in the present invention is Glauber's salt, and the main component is aqueous sodium sulfate. In the general Chinese medicine field, Glauber's salt can be used as a soft stool, which is also called Xuan Ming powder or Yuan Ming powder. According to the study by the inventors, in addition to being used as a Chinese medicine, Glauber's salt, when used as a cleaning agent, not only dissolves in water, but also rapidly softens the hardened surface of dirt and oil, so that the natural surfactant can be smoothly penetrated. The interior is more completely cleaned.

According to the actual test results of the applicant, the appropriate amount of thenardite combined with appropriate natural surfactants can produce high-efficiency emulsification decomposition of stubborn oil and grease. The proper proportion of the two can make the foam structure of the detergent. It is easy to clean and easy to clean, and therefore achieves water saving and biodegradability. That is, when the application amount of the Glauber's salt is less than 25 parts by weight, the speed of softening the surface of the dirt is slightly insufficient, and the cleaning effect is slightly slow, and when the amount of the Glauber's salt is more than 35 parts by weight, although the softening speed of the dirt can be increased, However, it excludes the proportion of other components and affects the final cleaning effect.

The sodium carbonate of the invention is a detergent, and the trisodium methylglycine diacetic acid (MGDA-Na ₃ ) is commonly used as a chelating agent, and the purpose is to replace the general synthetic detergent. EDTA that causes serious damage to the environment and ecology. According to the study by the inventors, the methylglycine diacetate trisodium salt used in the present invention can make the chelation of the detergent in the heavy metal more complete, and in addition to removing the dirt, it can also replace the zeolite to remove the calcium phosphate. The scale precipitates metal ions, and the biodegradation degree of methylglycine diacetate trisodium salt is more than 80% (28 days). Therefore, replacing EDTA with methylglycine diacetate trisodium salt can not only improve the composition. The cleaning effect on heavy metals can also reduce the impact of detergents on the environment and ecology.

The cleaning aid of the present invention can be divided into two main additives and a secondary additive, wherein the main additive comprises: 0.5 to 1.0 part by weight of methyl cellulose; and 1 to 6 parts by weight of alkyl glucoside (alkyl glucoside). 0.1 to 1.0 part by weight of sodium polyacrylate; 5 to 10 parts by weight of sodium percarbonate; and 5 to 10 parts by weight of sodium metasilicate.

The additive comprises: 0.3 to 2 parts by weight of carboxymethyl cellulose thickener (CMC-T); 3 to 10 parts by weight of glycerol; chlorine dioxide of 250 ppm or less; and 3~ 10 parts by weight of vegetable oil Triglyceride.

The methyl cellulose added by the invention has the functions of thickening, protecting and dispersing, and the alkyl glycoside can eliminate the lime in the tap water and avoid calcification. The sodium polyacrylate can be used as a softener and a thickener, and In the present invention, since the sodium polyacrylate is polymerized from acrylic acid (CH ₂ CHCOOH) and sodium acrylate [-CH ₂ CH(COONa)-], it has a negative charge to form a polymer repeatedly, which is high in absorption. The amount of moisture reaches the moisturizing function, and it can also soften the hardening substance in the tap water to improve the cleaning power of the detergent and at the same time assist the thickening effect of the methyl cellulose. Since sodium polyacrylate has a better water absorption effect, when the detergent is discharged into the natural world, the water content of the arid soil can also be increased, and the effect on the crop and the climatic temperature can be adjusted.

In addition, since the synthetic detergent has a strong acid and a strong alkali component, after washing, the skin in contact with it may have problems such as rapid loss of moisture, drying, accelerated aging, etc., and the present invention employs alkyl glycoside and poly The combination of sodium acrylate can provide better protection for the oil during the cleaning process and produce water content of more than 300 times, so it can produce very good moisturizing effect on the skin.

The sodium percarbonate and sodium metasilicate of the present invention are used as a bleaching agent, and the carboxymethyl cellulose powder is a food grade additive and a kind of thickener, and the added glycerin of the invention can improve the composition. Moisturizing and anti-freezing effect, the added chlorine dioxide can improve the bactericidal effect of the composition. That is, it is known from the known scientific literature that chlorine dioxide is a di-oxidant rather than a chlorinating agent, which has strong oxidizing ability and can kill bacteria and viruses, so it has been listed as highly efficient by the World Health Organization (WTO). Fast A1 grade 4th generation fungicide. The bitter oil of the present invention, also known as eucalyptus oil, is a biodegradable and non-toxic bactericide, and has an excellent moisturizing effect and can be used for treating skin diseases such as eczema, skin allergies and the like.

The beneficial effects of the invention are: using a certain proportion of Glauber's salt to rapidly soften the hardened surface of oil and dirt, and at the same time allowing the natural surfactant to smoothly penetrate into the interior of the grease for complete cleaning, the above composition not only does not contain, for example, formaldehyde, benzene. The environmentally harmful components such as phosphors, EDTA, nonylphenol, heavy metals, etc., can also make the biodegradable ratio as high as 95% or more, so the detergent composition of the present invention is not only environmentally friendly but also has a better cleaning effect. .
