Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and particularly relates to a decontamination toilet cleaning liquid and a preparation method thereof. Background Art

[0002] Toilet cleaner is a detergent specifically designed to clean and disinfect toilets and bathroom ceramic surfaces. Containing powerful detergents, it effectively removes urine scale, limescale, and stubborn stains. It also kills bacteria, viruses, and mold, maintaining a clean bathroom.

[0003] As a cleaning agent specifically used to clean toilets and bathroom facilities, toilet cleaners have the following technical problems in their formulation and production process. (1) Corrosiveness control: Toilet cleaners usually contain strong acids, such as hydrochloric acid, to help remove scale and stains. However, excessive acidity may cause corrosion to metal parts, ceramic surfaces and other materials, affecting their service life. (2) Formula stability: The various ingredients in the formula (such as acids, surfactants, fragrances, corrosion inhibitors and antioxidants) must remain stable during storage to avoid stratification, precipitation or deterioration. (3) Safety and health effects: Strong acidic ingredients and volatile substances may cause irritation or damage to the user's skin, eyes and respiratory system. In addition, improper use or mixing with other cleaning agents may produce toxic gases, such as chlorine. (5) Cleaning efficiency: The product needs to effectively remove stains in a short time, but not be so strong that it damages the surface being cleaned. Finding the right balance between detergency and protection is a technical challenge.

[0004] To improve cleaning efficiency, commercially available toilet cleaners often incorporate surfactants such as oleic acid soap and Gemini surfactants. However, these surfactants are easily oxidized by oxygen above the liquid, consuming oxygen and generating negative pressure. When the container is capped, air is drawn in, causing the packaging container to flatten, severely impacting the product's appearance and brand image. To improve this flattening, existing technologies typically add antioxidants such as tea polyphenols and tocopherols to toilet cleaners. However, under the influence of the strong acids in toilet cleaners, the antioxidant effects of tea polyphenols and tocopherols decrease after long-term storage, and they may even react with other components to form byproducts, posing safety and health risks.

[0005] Therefore, there is an urgent need for a decontamination toilet cleaner with good decontamination effect, slow-release effect, and a non-flat bottle, and a preparation method thereof. Summary of the Invention

[0006] The purpose of the present invention is to provide a decontamination toilet cleaning liquid and a preparation method thereof.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A decontamination toilet cleaning liquid, comprising the following components in parts by weight: 72-78 parts of concentrated hydrochloric acid, 6-10 parts of fatty alcohol polyoxyethylene ether, 5-8 parts of oleylamine polyoxyethylene ether, 4-7 parts of a surfactant composition, 3-6 parts of a mixed alcohol block polyether, 7-10 parts of a surfactant compound, 4-7 parts of a fragrance, and 25-30 parts of water;

[0009] The surfactant composition comprises the following components in parts by mass: 81-85 parts of water, 10-14 parts of trisodium nitrilotriacetate, and 9 parts of a detergent; the detergent comprises a solubilizer, an emulsifier, and water in a mass ratio of 30-35:50-54:12-15; the solubilizer is a mixture of dodecyl primary amine and polyethylene glycol in a mass ratio of 1:3-5.

[0010] The dodecyl primary amine is purchased from Shandong Paini. The polyethylene glycol can be polyethylene glycol 200 and / or polyethylene glycol 400.

[0011] The emulsifier is isomeric decanol polyoxyethylene ether, purchased from Lianhong Chemical, model: IP1007.

[0012] Trisodium nitrilotriacetate, CAS: 5064-31-3.

[0013] Furthermore, the mass concentration of the concentrated hydrochloric acid is 36%-37.5%.

[0014] Furthermore, the fatty alcohol polyoxyethylene ether is a mixture of AEO-3, AEO-7 and AEO-9 in a mass ratio of 1:1.3-1.6:0.4-0.8.

[0015] Oleylamine polyoxyethylene ether was purchased from Shandong Longhui Chemical Co., Ltd., specification: OA18E10.

[0016] Furthermore, the raw materials for preparing the mixed alcohol block polyether include: a starting alcohol, a block monomer and potassium hydroxide, the molar ratio of the starting alcohol to the block monomer is 1:10-12, and the potassium hydroxide is 0.5-0.6% of the total molar amount of the starting alcohol and the block monomer; the starting alcohol is isomeric tridecanol and C12-C14 alcohol, and the molar ratio of isomeric tridecanol and C12-C14 alcohol is 9-11:1; the block monomers are ethylene oxide and propylene oxide, and the molar ratio is 71-75:30.

[0017] Furthermore, the preparation method of the mixed alcohol block polyether is as follows: mixing the starting alcohols, adding them together with potassium hydroxide into a reactor, first adding ethylene oxide, then adding propylene oxide, and reacting at 140-150° C. for 6-8 hours to obtain the obtained product.

[0018] In order to avoid the flat bottle phenomenon, the decontamination toilet cleaner of the present invention does not use oleic acid soap and Gemini surfactant, and at the same time adds a surfactant composition and a mixed alcohol block polyether, which not only avoids the flat bottle phenomenon but also ensures the decontamination effect. The solubilizer can increase the solubility of stains that are difficult to dissolve in water, helping them to disperse in water, making it easier to adhere to the clean surface and spread; the emulsifier allows oily stains and aqueous media to form a stable emulsion, enhancing the spreading ability of the liquid; the unique molecular structure of the mixed alcohol block polyether enables it to form a thin and stable adsorption layer on the interface, promoting the spreading of the toilet cleaning liquid on the solid surface. The compounding of the surfactant composition and the mixed alcohol block polyether reduces the surface tension, allowing the toilet cleaning liquid to spread rapidly on the solid surface, thereby improving the cleaning efficiency. However, the addition of the above two components to the decontamination toilet cleaner at the same time results in the long-term storage stability of the decontamination toilet cleaner being unsatisfactory, and stratification or precipitation is prone to occur.

[0019] Furthermore, the surfactant formulation includes the following components in parts by weight: 7-10 parts of Evonik CQ100S, 2-5 parts of hexadecyltrimethylammonium chloride, 1-4 parts of styraxyl acetate.

[0020] The present invention adds a surfactant compound to a decontamination and toilet cleaning liquid to improve the long-term storage stability of the decontamination and toilet cleaning liquid. Different types of surfactants may have different hydrophilic-lipophilic balances (HLB values). The incompatibility between the surfactant composition and the mixed alcohol block polyether in the decontamination and toilet cleaning liquid is relatively poor. At the same time, due to the interaction with other ingredients in the toilet cleaning liquid, the more hydrophobic surfactants may aggregate and precipitate from the solution over time, resulting in stratification. The surfactant compound can act as a solubilizer, helping the two previously incompatible surfactants to better dissolve and stabilize in the solution. At the same time, under these conditions, the corrosiveness of the decontamination and toilet cleaning liquid is improved.

[0021] The present invention also provides a method for preparing a decontamination toilet cleaning liquid, the preparation method comprising the following steps:

[0022] Step S1, mixing concentrated hydrochloric acid and water to obtain component A;

[0023] Step S2, mixing the remaining components and stirring evenly to obtain component B;

[0024] Step S3: Mix component A and component B, stir them evenly, and then pack and seal them.

[0025] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0026] 1. The decontamination toilet cleaner of the present invention can be quickly spread on hard surfaces such as toilet walls, is not easy to roll off, and can quickly spread and penetrate into dead corners that cannot be sprayed, which is beneficial to improving the cleaning effect.

[0027] 2. In order to avoid the flat bottle phenomenon, the decontamination toilet cleaner of the present invention does not use oleic acid soap and Gemini surfactant, and adds a surfactant composition and a mixed alcohol block polyether, which not only avoids the flat bottle phenomenon but also ensures the decontamination effect.

[0028] 3. The present invention adds a surfactant compound to the decontamination and toilet cleaning liquid, which can improve the long-term storage stability of the decontamination and toilet cleaning liquid. At the same time, under this condition, the corrosiveness of the decontamination and toilet cleaning liquid is also improved. DETAILED DESCRIPTION

[0094] Performance Testing

[0095] The properties of the decontamination and toilet cleaning liquids prepared in Examples 1-3 and Comparative Examples 1-8 were measured, as follows:

[0096] 1. Spreading performance is characterized by the contact angle on the paraffin film surface.

[0097] 2. Each group of 10 bottles of toilet cleaner is made of 1mm thick plastic with the bottle caps tightly closed. After 30 days, their deformation is observed. Among them, A means that all 10 bottles are basically intact and have no deformation; B means that more than 3 bottles have slight deformation; C means that more than 3 bottles have serious deformation.

[0098] 3. Refer to GB / T38498 2020 "Evaluation method for metal corrosion of disinfectants" to determine the metal corrosion.

[0099] 4. Close the bottle cap of toilet cleaner tightly and place it at room temperature (25℃) for one year to observe whether there is precipitation or stratification.

[0100] Table 1 Performance test results

[0101]

[0102]

[0103] From the above performance test results, it can be seen that the comprehensive performance of the decontamination and toilet cleaning liquids of Examples 1-3 is excellent, especially the comprehensive performance of Example 1 is the most outstanding, which is mainly due to the effect produced by the synergistic effect of various components.

[0104] However, the comparative examples did not adopt the necessary technical solutions, resulting in significantly worse performance tests than the examples. In comparative examples 1-6, the ratios of the surfactant composition, mixed alcohol block polyether, and surfactant compound were changed. It can be seen that the decontamination effect, sustained-release effect, and stability decreased, proving that the compounding scheme of these three components has an important influence on the performance of the decontamination toilet cleaner. The above experimental results further demonstrate the importance of the technical solution defined in the present invention for its technical effects.

[0105] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
