Abstract
Description
Technical Field
[0001] This application belongs to the field of chemical materials technology, and in particular relates to a rheology modifier and its preparation method, as well as daily chemical products. Background Technology
[0002] Rheology modifiers are a class of raw materials used in multi-component liquid and semi-liquid products. They are substances that can increase the viscosity of a product and change its rheological properties, giving the product characteristics such as high yield stress and high thixotropic index, and achieving properties such as product storage stability, anti-settling, and anti-sagging.
[0003] Rheology modifiers can be divided into two categories: natural and synthetic. Natural rheology modifiers are mainly derived from plants and seaweed, such as carrageenan, xanthan gum, and alginic acid. These substances can form stable emulsions and gels in cosmetics, while also providing moisturizing and antioxidant effects. Due to the limited availability and high cost of natural rheology modifiers, most daily chemical product manufacturers choose to use synthetic thickening rheology modifiers. There are many types of synthetic rheology modifiers, including hydroxyethyl cellulose, polyacrylamide, and polysorbate. While these substances are less expensive, their stability and viscosity adjustment capabilities need improvement. Furthermore, some synthetic rheology modifiers may irritate the human body and generate large amounts of waste gas and wastewater during the synthesis process, which is detrimental to environmental protection.
[0004] It is evident that existing synthetic rheology modifiers have issues such as insufficient stability and viscosity adjustment capabilities, high irritation to the human body, significant environmental pollution, and unfavorable conditions for industrialization. Summary of the Invention
[0005] The purpose of this application is to provide a rheology modifier that addresses the problems of existing synthetic rheology modifiers, such as insufficient stability and viscosity adjustment capabilities, high irritation to the human body, significant environmental pollution, and unfavorable conditions for industrialization.
[0006] The embodiments of this application are implemented as follows: a rheology modifier comprises the following raw materials in parts by mass:
[0007] The ingredients are: 1-10 parts organic bentonite, 10-30 parts sulfonic acid, 1-8 parts PVA, 10-30 parts nonionic surfactant, 0.1-1 parts sodium hydroxide, 1-10 parts polyglycerol ester, and 35-50 parts water.
[0008] Another objective of this application is a method for preparing a rheology modifier, comprising:
[0009] Weigh the raw materials according to the above rheology modifier formula and set aside;
[0010] Organic bentonite was placed in water and subjected to ultrasonic treatment to obtain a bentonite dispersion.
[0011] Sulfonic acid and sodium hydroxide were added to the bentonite dispersion and the mixture was stirred to obtain a first mixture.
[0012] At a temperature of 80℃-90℃, PVA and polyglycerol ester are added to the first mixture and stirred for 50-70 minutes. The mixture is then cooled to 65-75℃ and stirred for another 50-70 minutes. A nonionic surfactant is added and stirred for another 110-130 minutes. After cooling, the rheology modifier is obtained.
[0013] Another objective of this application is to provide a daily chemical product, which includes the aforementioned rheology modifier.
[0014] The rheology modifier provided in this application is prepared by compounding organic bentonite, sulfonic acid, PVA, nonionic surfactant, sodium hydroxide, and polyglycerol ester in a specific mass ratio. When applied to daily chemical products, it can improve the rheological properties of these products, increase their viscosity, enhance storage stability, and result in products with high detergency and recycle performance. Furthermore, it possesses the effect of suspending fragrance and is human-friendly and non-irritating. In addition, the raw materials used in this rheology modifier are simple and readily available, the preparation process is simple, green, and pollution-free, and can be rapidly industrialized. Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0016] This application addresses the problems of existing synthetic rheology modifiers, such as insufficient stability and viscosity adjustment capabilities, high irritation to humans, significant environmental pollution, and hindering industrialization. It provides a rheology modifier prepared by compounding organic bentonite, sulfonic acid, PVA, nonionic surfactant, sodium hydroxide, and polyglycerol ester in a specific mass ratio. When applied to daily chemical products, it improves the rheological properties of these products, increases their viscosity, enhances storage stability, and results in products with high detergency and recycle performance. Furthermore, it provides the effect of suspending fragrances and is human-friendly and non-irritating. In addition, the raw materials used in this rheology modifier are simple and readily available, the preparation process is simple, environmentally friendly, and can be rapidly industrialized.
[0017] Specifically, this application provides a rheology modifier comprising the following parts by weight of raw materials:
[0018] 1-10 parts organic bentonite, 10-30 parts sulfonic acid, 1-8 parts PVA, 10-30 parts nonionic surfactant, 0.1-1 parts sodium hydroxide, 1-10 parts polyglycerol ester, and 35-50 parts water.
[0019] In the embodiments of this application, the organobentonite is a white to light yellow flowable powder, more preferably a white flowable powder. Preferably, the particle size (through 400 mesh) of the organobentonite is >90%, more preferably >95%. The finer and more uniform the particle size of the organobentonite, the better the storage stability of the corresponding rheology modifier at the same addition amount.
[0020] In the embodiments of this application, the specific gravity of the organic bentonite should not be too high, otherwise it will lead to a decrease in the yield stress of the obtained rheology modifier and poor rheological effect. Based on the research in this application, the specific gravity (25℃) of the organic bentonite is determined to be ≤2.7 g / cm³. 3 More preferably ≤2.6g / cm 3 The lower the specific gravity of organic bentonite, the higher the yield stress of the rheology modifier and the better the rheological effect for the same amount of addition.
[0021] In the embodiments of this application, if the molecular weight of PVA is too large, it will be difficult to dissolve, and the viscosity of the rheology modifier will increase, affecting the application of the rheology modifier. However, if the molecular weight is too small, the rheological effect of the rheology modifier will be reduced. Based on the research determined in this application, the molecular weight of the PVA (M...) is... W It should be controlled between 80,000 and 150,000.
[0022] In the embodiments of this application, the nonionic surfactant is at least one of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acid polyoxyethylene ester, polyoxyethylene alkylamine, and polyoxyethylene alkylamide.
[0023] In the embodiments of this application, the polyglycerol ester is at least one of triglyceride monostearate, tetraglyceride monolaurate, tetraglyceride laurate, diglyceride stearate, and triglyceride myristate.
[0024] In a preferred embodiment of this application, the rheology modifier comprises the following raw materials in parts by weight:
[0025] 5 parts organic bentonite, 20 parts sulfonic acid, 8 parts PVA, 20 parts nonionic surfactant, 0.59 parts sodium hydroxide, 5 parts polyglycerol ester, and 45.41 parts water.
[0026] This application also provides a method for preparing a rheology modifier, comprising:
[0027] Weigh the raw materials according to the above rheology modifier formula and set aside;
[0028] Organic bentonite was placed in water and subjected to ultrasonic treatment to obtain a bentonite dispersion.
[0029] Sulfonic acid and sodium hydroxide were added to the bentonite dispersion and the mixture was stirred to obtain a first mixture.
[0030] At a temperature of 80℃-90℃, PVA and polyglycerol ester are added to the first mixture and stirred for 50-70 minutes. The mixture is then cooled to 65-75℃ and stirred for another 50-70 minutes. A nonionic surfactant is added and stirred for another 110-130 minutes. After cooling, the rheology modifier is obtained.
[0031] In this process, bentonite and water are first ultrasonically treated to facilitate the formation of a three-dimensional cascade structure in the bentonite, resulting in a suspension effect in the product. This allows it to be used in daily chemical products as a suspended fragrance. The addition of sulfonic acid and sodium hydroxide promotes their uniform mixing. If PVA and polyglycerol ester are added first, the increased viscosity of the system would easily lead to uneven mixing of sulfonic acid and sodium hydroxide. Adding PVA and polyglycerol ester at a temperature of 80-90℃ takes into account the solubility of PVA and the viscosity of the system. Finally, the surfactant is added because surfactants tend to foam, and adding them first would hinder production.
[0032] This application also provides a daily chemical product, which includes the above-mentioned rheology modifier. The daily chemical product includes at least one of laundry detergent and laundry pods. The preparation of the daily chemical product can employ existing mature formulations and preparation methods. For example, it can be obtained by adding sodium linear alkylbenzene sulfonate, sodium fatty alcohol polyoxyethylene ether sulfate, and ammonium fatty alcohol polyoxyethylene ether sulfate to water at a temperature of 40-45°C, stirring, then heating to 60°C and adding sodium citrate and citric acid, stirring, then cooling to 45°C and adding NaCl, the above-mentioned rheology modifier, and fragrance, and stirring.
[0033] The following are embodiments of some implementations of this application, which are not intended to limit the scope of this application.
[0034] Furthermore, it should be noted that all materials and processing methods appearing in this application, unless otherwise stated, are common materials and familiar technical means in the art. The numerical values given in the following embodiments are as accurate as possible; however, those skilled in the art will understand that due to unavoidable measurement errors and experimental operation problems, each number should be understood as an approximation rather than an absolutely accurate value.
