Description

Technical Field

[0001] The present application relates to the technical field of detergents, and more specifically, to a sun-resistant dishwashing detergent composition and a preparation method thereof. Background Art

[0002] Currently, most dishwashing detergents on the market are non-transparent packaging products, colorless and transparent or slightly colored transparent packaging products. Some manufacturers choose colored packaging to give the product a different color sense, but during use, it is found that most of the products are colorless and transparent, which to a certain extent will cause consumers to have a sensory gap.

[0003] As a cleaning agent for tableware and kitchen utensils, the design of dishwashing detergent needs to consider not only its appearance but also its safety. Although traditional industrial pigments can make detergents maintain a long-lasting and stable color appearance, they pose a potential threat to human health. Therefore, in order to pursue visual appeal and product differentiation, using food pigments to give detergents color has become the only solution.

[0004] However, food colorings are often susceptible to fading under the influence of light, especially under ultraviolet light, which greatly reduces the aesthetics of detergents and consumer acceptance. Summary of the invention

[0005] In order to improve the light-fast stability of food pigments in detergents, the present application provides a light-fast dishwashing detergent composition and a preparation method thereof.

[0006] In a first aspect, the present application provides a sun-resistant dishwashing detergent composition, which adopts the following technical scheme: a sun-resistant dishwashing detergent composition, comprising sodium fatty alcohol polyoxyethylene ether sulfate, an amine oxide surfactant and fatty alcohol polyoxyethylene ether.

[0007] Fatty alcohol polyoxyethylene ether sodium sulfate is an anionic surfactant, amine oxide surfactant is an amphoteric surfactant, and fatty alcohol polyoxyethylene ether is a nonionic surfactant. By adopting the above technical scheme, the detergent composition composed of fatty alcohol polyoxyethylene ether sodium sulfate, amine oxide surfactant and fatty alcohol polyoxyethylene ether not only has excellent wetting, decontamination, emulsification and foaming properties, but also has high stability, which can provide stable environmental conditions for edible pigments, and is conducive to improving the light-fastness stability of edible pigments in detergents.

[0008] Preferably, the sun-resistant dishwashing detergent composition is composed of the following components in percentage by weight: Fatty alcohol polyoxyethylene ether sodium sulfate 2-15%, amine oxide surfactant 1-10%, fatty alcohol polyoxyethylene ether 1-10%, chelating agent 0.1-0.5%, pH regulator 0.2-1%, preservative 0.1-0.5%, and the balance is water.

[0009] By adopting the above technical solution, the food coloring is added to the above detergent composition to prepare a colored detergent sample. 2 After irradiation in a xenon lamp box for 12 hours, there was no obvious change in color. Therefore, the food coloring has excellent stability in the above detergent composition.

[0010] Preferably, the amine oxide surfactant is one or more of dodecyl dimethyl amine oxide, cocamidopropyl amine oxide and lauryl amide propyl amine oxide.

[0011] Preferably, the amine oxide surfactant is dodecyl dimethyl amine oxide.

[0012] By adopting the above technical solution, the above-mentioned types of alkylamine oxides and amidopropylamine oxides not only have excellent cleaning, emulsifying and foaming abilities, but also have high compatibility and synergistic effects with fatty alcohol polyoxyethylene ether sodium sulfate and fatty alcohol polyoxyethylene ether. The detergent samples prepared by using them have excellent detergency and pigment light-fastness stability. In particular, the detergent composition prepared by using dodecyl dimethylamine oxide and the detergent sample mixed with edible pigments has a light wavelength of 420nm and an irradiance of 1.50W / m 2 After irradiation in a xenon lamp box for 12 hours, there was no obvious color change.

[0013] Preferably, the fatty alcohol polyoxyethylene ether is one or two of Tomakleen G-16AP, AEO-9 and AEO-7.

[0014] Preferably, the fatty alcohol polyoxyethylene ether is Tomakleen G-16AP.

[0015] By adopting the above technical scheme, the above fatty alcohol polyoxyethylene ether has good hydrophilicity and emulsification stability, and has good compounding performance with raw materials such as amine oxide surfactants and fatty alcohol polyoxyethylene ethers. The detergent sample prepared therefrom has both excellent detergency and light-resistant stability.

[0016] In a second aspect, the present application provides a method for preparing a sun-resistant dishwashing detergent composition, using the following technical solution: A method for preparing a sun-fast dishwashing detergent composition comprises the following steps: S1: Stir and mix fatty alcohol polyoxyethylene ether sodium sulfate, amine oxide surfactant, fatty alcohol polyoxyethylene ether, chelating agent and 30-50% water to obtain a mixed solution; S2: After the pH adjuster and the remaining water are stirred and mixed evenly, the pH adjuster and the remaining water are added to the mixed solution, and then the preservative is added and stirred and mixed evenly to obtain a sun-resistant dishwashing detergent composition.

[0017] By adopting the above technical scheme, three surfactants and a chelating agent are first added into water, stirred to form a stable mixed solution, the pH value is adjusted, and then a preservative is added to prepare a detergent composition with high pigment sun-fastness stability and excellent cleaning effect.

[0018] In summary, this application has the following beneficial effects: The detergent composition of the present application, which is a compound of fatty alcohol polyoxyethylene ether sodium sulfate, amine oxide surfactants and fatty alcohol polyoxyethylene ether, not only has excellent decontamination ability, but also avoids the influence of impurities brought by different surfactants, can provide stable environmental conditions for edible pigments, and effectively reduces the influence of light, temperature, pH and metal ions on the molecular structure of edible pigments. Therefore, without using traditional ultraviolet absorbers, the detergent composition of the present application can still ensure the stability of edible pigments and extend the sun resistance period of edible pigments in the detergent composition.
