Description

A solid detergent tablet, its preparation method and usage method Technical Field

[0001] This invention belongs to the field of detergent technology, and particularly relates to a solid detergent tablet and its preparation and usage methods. Background Technology

[0002] Detergents are products specifically formulated for cleaning during the washing process. Their main components typically consist of surfactants, builders, and additives. There are many types of detergents; based on the type of dirt they remove, they can be divided into heavy-duty detergents and light-duty detergents; based on their physical form, they can be in various forms such as powder, block, paste, slurry, and liquid.

[0003] Solid detergent tablets have been around for a long time, but currently available products dissolve very thinly. When existing solid detergent tablets are added to water, the resulting solution has a viscosity of about 1 mPa·s, the same as water. However, the viscosity of detergent liquid is about 1000 mPa·s, much higher than that of the solution obtained by adding solid detergent tablets to water, and the texture is also significantly different. Consumers prefer higher viscosity solutions. Summary of the Invention

[0004] This invention provides a solid detergent tablet, its preparation method, and its usage method, aiming to solve the above-mentioned problems.

[0005] The present invention is achieved by providing a solid detergent tablet comprising a base material and a viscosity modifier in a mass ratio of 11-15:1.

[0006] Preferably, the viscosity modifier comprises at least one or more combinations of cellulose ether and reverse emulsion, wherein the hydroxyl groups in the cellulose ether have been replaced by one or more of the three hydroxyl groups present in the cellulose ring.

[0007] Preferably, the cellulose ether is hydroxypropyl methylcellulose. Those skilled in the art know that hydroxypropyl methylcellulose (HPMC) belongs to the class of cellulose ethers, wherein the hydroxyl groups have been replaced by one or more of the three hydroxyl groups present in the cellulose ring.

[0008] Preferably, the base material comprises the following raw materials in parts by weight: 15-30 parts polyvinyl alcohol, 15-30 parts sodium dodecyl sulfate, 1-5 parts sodium citrate, 1-5 parts tetrasodium ethylenediaminetetraacetate, 1-5 parts sodium dodecylbenzene sulfonate, 1-5 parts sodium fatty alcohol polyoxyethylene ether sulfate, 1-10 parts glycerol, 1-5 parts isomeric alcohol ether, 1-5 parts protease, and 1-5 parts amylase.

[0009] Preferably, the base material further includes 1-5 parts of modified nano-tourmaline. By adding modified nano-tourmaline, on the one hand, the far-infrared rays emitted by tourmaline can activate water molecules, causing them to resonate, thereby strengthening the interfacial activation effect between dirt and water and improving the washing and cleaning effect. On the other hand, tourmaline has adsorption properties and can adsorb viscosity modifier powder particles, which can be combined with other components after the solid detergent tablets are dissolved.

[0010] Preferably, the preparation method of the modified nano-tourmaline is as follows: Take tourmaline, clean the surface, dry it and then perform preliminary crushing; then place it in a muffle furnace and heat it to 900-1000℃, calcine it at a constant temperature for 1-2 hours, cool it and grind it to a particle size of 200-300 mesh; then add 25-35 vt% hydrochloric acid solution, soak it for 2-3 hours, take it out and filter it, wash it with deionized water, dry it and grind it into nano powder, then add it and heat it to 500-600℃, then pass water vapor to expand the pores, cool it and wash it with water and dry it to obtain modified nano-tourmaline; by calcining the tourmaline, water in different states in the tourmaline crystal structure is removed, making the internal structure loose and porous, increasing the specific surface area, then the surface of the tourmaline is modified by hydrochloric acid corrosion, so that the surface of the tourmaline particles forms a stable porous structure, and then water vapor is passed in to further expand the pores, so that the adsorption of tourmaline is improved, and it can adsorb viscosity modifier powder particles and form a stable system with other components.

[0011] Preferably, the viscosity modifier further includes modified soy protein isolate, modified betaine, and modified polyethylene glycol.

[0012] Preferably, the mass ratio of hydroxypropyl methylcellulose, modified soy protein isolate, modified betaine, and modified polyethylene glycol is 3-5:1-2:1:1-3.

[0013] Preferably, the modified soy protein isolate is prepared as follows: Soy protein isolate is spread evenly to a thickness of 3-5 mm and placed in a low-temperature plasma generator for treatment for 150-180 seconds. Then, water is added to prepare a soy protein isolate solution with a mass concentration of 30-40 mg / mL. The solution is then ultrasonically treated for 15-20 minutes. The ultrasonically treated soy protein isolate solution is placed in a PE bag, spread evenly to a thickness of 1-3 cm, and then subjected to electron beam irradiation. The irradiated soy protein isolate solution is then vacuum-dried to obtain the modified soy protein isolate.

[0014] Soy protein isolate is treated with a low-temperature plasma generator, which improves its solubility, gelling properties, emulsifying properties, and emulsion stability. Ultrasonic treatment causes the protein to move rapidly, reducing protein aggregation, improving its molecular extensibility and flexibility, and exposing more hydrophilic and hydrophobic active groups, thereby regulating the protein's spatial structure and surface activity. Electron beam irradiation further enhances its gelling and emulsifying properties, resulting in better thickening effects.

[0015] Preferably, the voltage of the low-temperature plasma generator is 60-90kV and the frequency is 50-80Hz, the ultrasonic treatment frequency is 20-30kHz and the power is 300-400W, the electron beam output energy of the electron beam irradiation treatment is 10MeV, and the electron beam irradiation absorbed dose is 8-10kGy.

[0016] Preferably, the modified betaine is prepared as follows: 10-16 parts by weight of cocamidopropyl hydroxysulfonate betaine, 1-2 parts by weight of tea saponin, and 60-70% ethanol solution are heated to 100-120°C while stirring for 30-40 minutes, and then vacuum dried to obtain modified betaine. The modification of betaine by tea saponin further reduces surface tension and increases surface activity, thereby improving emulsification, dispersion, and thickening effects. The modified betaine can synergistically combine with other surfactants in solid detergent raw materials, exhibiting excellent thickening effects.

[0017] Preferably, the modified polyethylene glycol is prepared as follows: 10-20 parts by weight of polyethylene glycol are added to 80-100 parts of water under stirring, heated to 50-60°C, 2-4 parts of 3-amino-1,2-propanediol and 1-3 parts of diethylamine are added, the temperature is raised to 75-85°C and stirred for 0.5-1 h, extracted with dichloromethane, precipitated with anhydrous diethyl ether, and vacuum dried to obtain modified polyethylene glycol. By grafting amino groups onto the ends of polyethylene glycol, the reactivity of polyethylene glycol can be effectively enhanced. When compounded with other components, they react with each other to form a macromolecular network structure, improving the thickening effect.

[0018] The present invention also provides a method for preparing the aforementioned solid detergent tablets, comprising the following steps:

[0019] Prepare viscosity modifiers and base materials;

[0020] Mix the base materials thoroughly to obtain mixture A;

[0021] Mixture A is laid on a thin film dryer and dried to obtain a sheet;

[0022] A viscosity modifier is added to the surface of the sheet, which is then rolled up, slit, and packaged to obtain solid detergent sheets.

[0023] Preferably, the viscosity modifier is in powder or granular form.

[0024] Preferably, the step of mixing and stirring the base materials to obtain mixture A specifically involves: adding polyvinyl alcohol to a mixer, heating it to 90°C while stirring, stirring until it is completely dispersed and uniform, then adding sodium dodecyl sulfate and stirring evenly, stirring slowly at a constant temperature for 28-32 minutes, and then letting it stand to defoam; adding glycerol, tetrasodium ethylenediaminetetraacetate, and sodium dodecylbenzenesulfonate and stirring evenly, lowering the temperature to 38-42°C, then sequentially adding sodium fatty alcohol polyoxyethylene ether sulfate, isomeric alcohol ether, protease, and amylase, stirring at a stirring speed of 15 r / min until completely uniform, and then adding sodium citrate and stirring evenly.

[0025] Preferably, the drying temperature is 80-90℃ and the drying time is 4-6 minutes.

[0026] Preferably, the step of adding viscosity modifier to the surface of the sheet specifically involves spraying viscosity modifier powder particles onto both sides of the sheet.

[0027] Preferably, the sheet is pretreated and a viscosity modifier is added to its surface, then dried and wound up. The pretreatment method is as follows: the sheet is first subjected to corona treatment, and then the sheet passes through a water vapor area at a speed of 0.2-0.4 m / s.

[0028] Preferably, the voltage of the corona treatment is 10-20kV, the frequency of the pulse peak voltage is 15-25kHz, and the temperature is 40-50℃.

[0029] The present invention also provides another method for preparing the aforementioned solid detergent tablets, comprising the following steps:

[0030] Prepare viscosity modifiers and base materials;

[0031] Mix the base material and viscosity modifier evenly to obtain mixture B;

[0032] Mixture B is laid on a film dryer and dried to obtain a sheet, which is then rolled up, cut, and packaged to obtain solid detergent tablets.

[0033] Of course, other methods can be used to obtain viscous detergents without too many restrictions.

[0034] The present invention also provides a method for using the above-mentioned solid detergent tablets, comprising the following steps:

[0035] Place the solid detergent tablets and water into a container;

[0036] Use after the solid detergent tablets have dissolved.

[0037] Preferably, the container includes a shell and a lid. The upper surface of the lid is provided with a placement groove, and the lower surface of the lid is provided with a connecting pipe. The connecting pipe is open at both ends and extends to the lower part of the inner cavity of the shell.

[0038] Compared with the prior art, the embodiments of this application have the following main advantages:

[0039] The solid detergent tablets provided by this invention can adjust the viscosity of the final detergent solution by adding a viscosity modifier, thereby meeting consumer needs.

[0040] After drying, the resulting sheet material is added with viscosity modifier powder particles. On the one hand, the process difficulty is not increased; on the other hand, the addition of viscosity modifier makes the product thicker after dissolving, resulting in a better customer experience.

[0115] Example 8

[0116] This invention provides a solid detergent tablet comprising a base material and a viscosity modifier in a mass ratio of 13:1. The preparation method of the solid detergent tablet, as shown in Figure 2, includes the following steps:

[0117] Prepare viscosity modifiers and base materials;

[0118] Mix the base materials thoroughly to obtain mixture A;

[0119] Mixture A is laid on a film dryer and dried to obtain a sheet. The drying temperature is 85°C and the drying time is 5 minutes.

[0120] The sheet is pretreated and then viscosity modifier powder particles are added to its surface. After drying, it is wound, slit, and packaged to obtain solid detergent sheets. In this embodiment, viscosity modifier powder particles are preferably sprayed on both sides of the sheet. The viscosity modifier includes hydroxypropyl methylcellulose, modified soy protein isolate, modified betaine, and modified polyethylene glycol. The mass ratio of hydroxypropyl methylcellulose, modified soy protein isolate, modified betaine, and modified polyethylene glycol is 4:1.5:1:2.

[0121] The base material comprises the following raw materials in parts by weight: 22 parts polyvinyl alcohol, 23 parts sodium dodecyl sulfate, 3 parts sodium citrate, 3 parts tetrasodium ethylenediaminetetraacetate, 3 parts sodium dodecylbenzenesulfonate, 3 parts sodium fatty alcohol polyoxyethylene ether sulfate, 5.5 parts glycerol, 3 parts isomeric alcohol ether, 3 parts protease, 3 parts amylase, and 3 parts modified nano tourmaline.

[0122] The modified nano-tourmaline is prepared as follows: Take tourmaline, clean the surface, dry it and then perform preliminary crushing; then place it in a muffle furnace and heat it to 900-1000℃, calcine it at a constant temperature for 1-2 hours, cool it and grind it to a particle size of 200-300 mesh; then add 25-35 wt% hydrochloric acid solution, soak it for 2-3 hours, take it out and filter it, wash it with deionized water, dry it and grind it into nano powder, then add it to heat it to 500-600℃, pass water vapor to expand the pores, cool it and wash it with water and dry it to obtain modified nano-tourmaline.

[0123] Specifically, the step of mixing and stirring the base materials to obtain mixture A is as follows: Polyvinyl alcohol is added to a mixer, heated to 90°C while stirring, and stirred until completely dispersed and uniform. Sodium dodecyl sulfate is then added and stirred evenly. The mixture is then slowly kept warm and stirred for 30 minutes before being allowed to stand to defoam. Glycerin, tetrasodium ethylenediaminetetraacetate, and sodium dodecylbenzenesulfonate are added and stirred evenly. The temperature is lowered to 40°C, and then sodium fatty alcohol polyoxyethylene ether sulfate, isomeric alcohol ether, protease, and amylase are added in sequence. The mixture is stirred at a stirring speed of 15 r / min until completely uniform. Sodium citrate is then added and stirred evenly.

[0124] In this embodiment, the modified soy protein isolate is prepared as follows: Soy protein isolate is spread evenly to a thickness of 4 mm and placed in a low-temperature plasma generator for 165 s. Water is then added to prepare a soy protein isolate solution with a mass concentration of 35 mg / mL. The solution is then ultrasonically treated for 18 min. The ultrasonically treated soy protein isolate solution is placed in a PE bag, spread evenly to a thickness of 2 cm, and then subjected to electron beam irradiation. The irradiated soy protein isolate solution is then vacuum-dried to obtain the modified soy protein isolate. The low-temperature plasma generator has a voltage of 75 kV and a frequency of 65 Hz. The ultrasonic treatment frequency is 25 kHz and the power is 350 W. The electron beam output energy of the electron beam irradiation treatment is 10 MeV, and the electron beam irradiation absorbed dose is 9 kGy.

[0125] In a specific implementation, the modified betaine is prepared as follows: 13 parts by weight of cocamidopropyl hydroxysulfonate betaine, 1.5 parts by weight of tea saponin and 65% ethanol solution are stirred and heated at 110°C for 35 minutes, and then vacuum dried to obtain modified betaine.

[0126] Specifically, the preparation method of the modified polyethylene glycol is as follows: by weight, 15 parts of polyethylene glycol are added to 90 parts of water under stirring, heated to 55°C, 3 parts of 3-amino-1,2-propanediol and 2 parts of diethylamine are added, the temperature is raised to 80°C and stirred for 0.7 h, extracted with dichloromethane, precipitated with anhydrous diethyl ether, and vacuum dried to obtain modified polyethylene glycol.

[0127] The pretreatment method is as follows: first, the sheet is subjected to corona treatment, and then the sheet passes through a water vapor zone at a speed of 0.3 m / s. The corona treatment roughens the surface of the sheet, improves its adsorption, and enables it to adsorb more viscosity modifier powder particles, thereby improving the thickening effect. The water vapor wets the surface of the sheet, allowing more viscosity modifier powder particles to adhere. Finally, drying ensures that the sheet and viscosity modifier powder particles are tightly bonded, further improving the thickening effect.

[0128] Preferably, the voltage of the corona treatment is 15kV, the frequency of the pulse peak voltage is 20kHz, and the temperature is 45℃.

[0129] Example 9

[0130] The present invention also provides a method for using the solid detergent tablets obtained in any of Examples 1-6, comprising the following steps:

[0131] Place the solid detergent tablets and water into a container;

[0132] Use after the solid detergent tablets have dissolved.

[0133] Preferably, as shown in Figure 4, the container includes a shell 1 and a cover 2. The shell 1 is preferably made of a transparent material. The upper surface of the cover 2 is provided with a placement groove for placing a cleaning sponge. The lower surface of the cover 2 is provided with a connecting tube 3. The connecting tube 3 is open at both ends and extends to the lower part of the inner cavity of the shell.

[0134] Comparative Example 1: The difference from Example 6 is that the modified soy protein isolate was replaced with ordinary soy protein isolate.

[0135] Comparative Example 2: The difference from Example 6 is that the modified betaine was replaced with ordinary betaine.

[0136] Comparative Example 3: The difference from Example 6 is that the modified polyethylene glycol is replaced with ordinary polyethylene glycol.

[0137] Comparative Example 4: The difference from Example 6 is that the modified soy protein isolate was replaced with ordinary soy protein isolate, the modified betaine was replaced with ordinary betaine, and the modified polyethylene glycol was replaced with ordinary polyethylene glycol.

[0138] Comparative Example 5: A commercially available solid detergent tablet.

[0139] Comparative Example 6: The difference from Example 8 is that the raw material of the sheet does not include modified nano-tourmaline.

[0140] experiment

[0141] Viscosity tests were performed on the solid detergent tablets prepared in Examples 1-8 and Comparative Examples 1-6 after dissolving them in water. The test results are shown in the table below:

[0142] Group Viscosity (mPa.s) Example 1 1000 Example 2 1050 Example 3 1100 Example 4 1000 Example 5 2050 Example 6 2065 Example 7 2060 Example 8 2600 Comparative Example 1 1450 Comparative Example 2 1410 Comparative Example 3 1420 Comparative Example 4 1200 Comparative Example 5 Comparative Example 6 2450

[0143] The results above show that the solid detergent tablets prepared by this invention are more viscous and provide a better customer experience. In particular, the addition of modified soy protein isolate, modified betaine, and modified polyethylene glycol to the viscosity modifier has a synergistic effect, which can further make the solid detergent tablets more viscous when dissolved in water. The addition of modified nano-tourmaline to the raw materials for preparing the tablets and the pretreatment of the tablets can further improve the solubility and viscosity of the solid detergent tablets.
