Description
Technical Field
The invention relates to the field of washing products, in particular to a concentrated alcohol detergent and a preparation method thereof.
Background
The detergent is a common cleaning article in daily life, can be used for cleaning tableware, cooktops and other articles in kitchens, and is added with the preservative in many detergents on the market in order to prolong the storage time of the detergent, so that the preservative is remained on the tableware to be harmful to certain extent when in use. The concentrated environment-friendly detergent indirectly reduces the transportation cost and the storage cost, saves energy, and has the appearance of more concentrated detergents on the market in order to respond to the concept of concentrated environment protection, but the concentrated detergents on the market are added with preservatives and contain a large amount of water, so that the concentration multiple of the concentrated detergents is generally 2 times, and the concentrated detergents cannot have a good decontamination effect.
Patent CN101979489A provides a super concentrated hand-washing detergent without moisture and preservative, which is made by compounding anionic surfactant and nonionic surfactant, and although the detergent contains no moisture, it contains a large amount of surfactant, which makes the detergent foam too much to be rinsed easily, and also can not be dissolved well in water at a lower temperature.
Disclosure of Invention
In order to solve the technical problems, the first aspect of the invention provides a concentrated alcohol detergent, wherein the raw materials of the concentrated alcohol detergent comprise, by mass, 10-20% of dodecylbenzene sulfonic acid, 25-45% of fatty acid diethanolamide, 5-15% of fatty alcohol-polyoxyethylene ether and a solvent which is supplemented to 100%; the solvent is ethanol and water; the weight ratio of the water to the ethanol is 1: (1-3).
In a preferred embodiment, the raw materials of the concentrated alcohol detergent comprise, by mass, 10-18% of dodecylbenzene sulfonic acid, 28-42% of fatty acid diethanolamide, 7-9% of fatty alcohol polyoxyethylene ether and solvent supplement to 100%.
In a preferred embodiment, the raw materials of the concentrated alcohol detergent comprise, by mass, 15% of dodecylbenzene sulfonic acid, 35% of fatty acid diethanolamide, 8% of fatty alcohol-polyoxyethylene ether and solvent supplement to 100%.
In one embodiment, the dodecylbenzene sulfonic acid is selected from at least one of linear alkylbenzene sulfonic acid, branched alkylbenzene sulfonic acid, and heavy alkylbenzene sulfonic acid.
In order to increase the detergency effect of the concentrated alcohol detergent, in a preferred embodiment, the dodecylbenzene sulfonic acid is linear alkyl benzene sulfonic acid.
In one embodiment, the fatty acid in the fatty acid diethanolamide is selected from caprylic acid, capric acid, lauric acid, myristic acid, coconut oil fatty acid, palmitoleic acid, and soybean oil fatty acid.
The synergistic effect of the fatty acid diethanolamide and the dodecylbenzene sulfonic acid is used in the system, so that the oil removal effect can be better increased, probably because when the fatty acid diethanolamide forms micelles, the linear alkylbenzene sulfonic acid can be embedded into the micelles of the fatty acid diethanolamide, so that the intermolecular repulsion among the fatty acid diethanolamide molecules is reduced, and the micelles are easier to form.
In a preferred embodiment, the fatty acid in the fatty acid diethanolamide is one of lauric acid, coconut oil fatty acid and soybean oil fatty acid.
In a more preferred embodiment, the fatty acid in the fatty acid diethanolamide is coconut oil fatty acid, in particular, the fatty acid diethanolamide is coconut oil fatty acid diethanolamide, type AES.
In one embodiment, the weight ratio of AES to dodecylbenzene sulfonic acid is 7: (2.5-4); preferably 7:3.
the dodecyl benzene sulfonic acid has better detergency, but the decontamination effect can not be well played when the dodecyl benzene sulfonic acid is singly used, the decontamination effect can be better played by using the synergistic effect of the fatty acid diethanolamide and the dodecyl benzene sulfonic acid in the system, but the dodecyl benzene sulfonic acid has certain irritation, and the synergistic effect of the AES and the dodecyl benzene sulfonic acid in the system not only can increase the oil removal effect of the concentrated alcohol detergent, but also can reduce the irritation brought by the dodecyl benzene sulfonic acid, so that the detergent is milder. However, it has been found that AES and dodecylbenzene sulfonic acid are required in specific weight ratios to achieve mild degreasing. Probably because the weight ratio of the two is 7: (2.3-2.5) the surface activity is optimized so that the detergent can diffuse in water quickly and be arranged more densely on the surface.
In one embodiment, the fatty alcohol-polyoxyethylene ether has an HLB value of 12 to 15; preferably 13.
In one embodiment, the fatty alcohol-polyoxyethylene ether has a hydroxyl number of 70 to 110mgKOH/g; preferably 95 to 100mgKOH/g.
In a preferred embodiment, the fatty alcohol polyoxyethylene ether is of type basf AEO-9.
The solubility of the fatty acid diethanolamide in water is poor, and the amount of the fatty acid diethanolamide used in the invention is large, so that the solubility of the concentrated alcohol detergent is poor, particularly the solubility of the concentrated alcohol detergent is poor at low temperature, but the detergent in the invention also has good solubility at low temperature, through a large number of experiments, the applicant speculates that a hydration layer can be formed in an aqueous solution due to an ethoxy structure in a certain amount of AEO-9 added in the system, so that the solubilization effect is certain, the solubility of the fatty acid diethanolamide can be increased, and meanwhile, the dodecylbenzene sulfonic acid has a small molecular area and can be inserted into a micelle of the AEO-9 and the fatty acid diethanolamide, so that the micelle is more compact.
In one embodiment, the raw material of the concentrated alcohol detergent further comprises an alkali.
In one embodiment, the weight of the base is 15 to 25% of the weight of the dodecylbenzene sulfonic acid; preferably 20%.
In one embodiment, the base is selected from at least one of sodium carbonate, sodium hydroxide, potassium hydroxide, triethanolamine, ethanolamine, diethanolamine.
In a preferred embodiment, the base is sodium hydroxide.
In one embodiment, the raw material of the concentrated alcohol detergent further comprises an acidic pH adjuster.
In one embodiment, the acidic pH adjusting agent is selected from at least one of acidic amino acids, citric acid, sorbic acid, tartaric acid, maleic acid, malic acid.
In a preferred embodiment, the acidic pH adjusting agent is citric acid.
In a preferred embodiment, the weight ratio of water to ethanol is 1: (1.8-2.3); more preferably 1:2.
the second aspect of the present invention provides a method for preparing a concentrated alcohol detergent, comprising the steps of:
(1) Heating water to 75-85 ℃, sequentially adding fatty acid diethanolamide and fatty alcohol-polyoxyethylene ether, and mixing and stirring for 15-25min to obtain a solution A;
(2) Mixing and stirring (1/4-1/2) parts by weight of ethanol, dodecylbenzene sulfonic acid and alkali uniformly to obtain a solution B;
(3) Cooling the solution A to 40-50 ℃, adding the rest ethanol, uniformly mixing, then adding the solution B, mixing and stirring for 25-40min to obtain a solution C;
(4) And cooling the solution C to room temperature, and adding an acidic pH regulator to regulate the pH value of the system to be neutral, thereby obtaining the concentrated alcohol detergent.
In a preferred embodiment, the method for preparing the concentrated alcohol detergent comprises the following steps:
(1) Heating water to 80 ℃, sequentially adding fatty acid diethanolamide and fatty alcohol-polyoxyethylene ether, and mixing and stirring for 20min to obtain a solution A;
(2) Mixing and stirring 1/3 of ethanol, dodecylbenzene sulfonic acid and alkali uniformly to obtain a solution B;
