Problems solved by technology

[0010] Chinese patent (patent No. CN1919991A) introduces a liquid detergent without chelating agent and inorganic additives. It does not consider the environmental friendliness of its washing products, and its washing amount is difficult to control, and the amount of foam is large, which is not conducive to saving water resources.
[0011] Most of the common washing liquids on the market only have a certain cleaning effect on mild stains, and are often powerless to deal with various heavy grease stains such as careless eating or work.

preparation example Construction

[0017] The preparation method of the cleaning agent containing microorganisms of the present invention comprises the following steps:

[0018] 1. Preparation of solvent: According to the weight ratio, take 5%-20% ethanol, 3%-5% isopropanol and 75%-90% water, and mix them.

[0019] 2. Preparation of solute: According to the weight ratio, take 55%-70% of alkylphenol polyoxyethylene ether-10, 29%-44.5% of glyceryl stearate and 0.5%-1% of sodium diacetate, mix .

[0020] 3. Cultivate the seed liquid: place three strains of Bacillus subtilis, Bacillus licheniformus, and Bacillus megaterium in a liquid medium in a constant temperature shaker at 27-32°C Shake culture until the number of bacteria reaches 1×10 7 CFU / ml-1×10 8 The seed solution is obtained by adjusting the pH to 6.0-7.0 and sterilizing.

[0021] The composition of culture medium and the weight ratio of each component are: beef extract: peptone: sodium chloride: glucose: dipotassium hydrogen phosphate=1-3: 1-3: 1-3: ...

Embodiment 1

[0031] Add 5% (g / g) ethanol, 5% (g / g) isopropanol, and 90% (g / g) water in a 500ml volumetric flask. Bacillus subtilis (Bacillus subtilis), Bacillus licheniformus (Bacillus licheniformus), and Bacillus megaterium (Bacillus megaterium) were respectively placed in a liquid medium in a constant temperature shaker at 27°C with a rotation speed of 150rpm. until the number of bacteria reaches at least 1×10 8 The seed liquid can be taken from the shaker above the order of magnitude per ml. The pH was adjusted to 7.0 with sulfuric acid. In a fermenter, sterilize at 105° C. for 15 minutes to obtain a seed liquid, which is added to the solvent. Add solute at last in mixed solution, solute composition is 55% (g / g) alkylphenol polyoxyethylene ether-10, 44% (g / g) glyceryl stearate and 1% (g / g) sodium diacetate , to obtain the microbial cleaner.

Embodiment 2

[0033]Add 20% (g / g) ethanol, 3% (g / g) isopropanol, and 77% water (g / g) in a 500ml volumetric flask. Bacillus subtilis (Bacillus subtilis), Bacillus licheniformus (Bacillus licheniformus), and Bacillus megaterium (Bacillus megaterium) were respectively placed in a liquid medium in a constant temperature shaker at 30°C with a rotation speed of 150rpm. until the number of bacteria reaches at least 1×10 7 The seed solution can be removed from the shaker above the CFU / ml-order of magnitude. The pH was adjusted to 6.0 with sulfuric acid. In a fermenter, sterilize at 105° C. for 15 minutes to obtain a seed liquid, which is added to the solvent. Finally, add solute to the mixed solution, the solute component is 59.5% (g / g) alkylphenol polyoxyethylene ether-10, 40% (g / g) glyceryl stearate and 0.5% (g / g) sodium diacetate , to obtain the microbial cleaner.

Abstract

The invention discloses a detergent containing microorganisms and a preparation method thereof. The detergent mainly comprises solute, solvent and bacillus, wherein the solute mainly comprises 55 to 70 weight percent of alkyl phenol polyethenoxy ether-10. 29 to 44.5 weight percent of tristearin and 0.5 to 1 weight percent of sodium diacetate; the solvent mainly comprises 5 to 20 weight percent of ethanol, 3 to 5 weight percent of isopropyl alcohol and 75 to 90 weight percent of water; the weight ratio of the solute to the solvent is 3-7:93-97; and the bacillus is Bacillus subtilis, Bacilluslicheniformis and Bacillus megatherium, and the total bacteria count of the bacillus is 2*10<4>CFU / ml-1*10<6> / ml magnitude order. The detergent has obvious deodorization effect, is clean, non-irritating, nontoxic and harmless, is quick and complete in biodegradation, reduces the content of organic substances in waste cleaning water, further reduces the aftertreatment cost of the waste water, has good economic benefit, environment-friendly benefit and social benefit and superior performance, and cannot cause secondary pollution.

Description

technical field [0001] The invention relates to the fields of environmental protection and daily cleaning products, in particular to a novel environment-friendly cleaning agent containing microorganisms and a preparation method thereof. Background technique [0002] With the rapid development of society, stench and eutrophication pollution have brought great harm to our life. [0003] Odor pollutants refer to all gas pollutants that stimulate the olfactory organs to cause people's disgust, unpleasantness, damage to human health and affect the quality of ambient air. The smell is unpleasant to the senses, and even endangers the physical health of the human body, such as dyspnea, nausea, chest tightness, and vomiting. The 1990 amendment to the Clean Air Act of the United States established more stringent air emission standards, increasing the original 8 harmful gas pollutants to 188, mainly based on the carcinogenicity, mutagenicity and reproductive properties of these chemic...
