[0007] In addition, in order to ensure the cleaning effect, the dishwasher is usually used under heating conditions, but in the environment with high water hardness, heating hard water will cause the heating tube to condense scale, thus affecting the washing effect
In addition, scale marks will also form on the surface of the tableware, seriously affecting the finish of the tableware

preparation example Construction
[0092] The preparation method of liquid phosphorus-free detergent composition, comprises the following steps:
[0093] 1) First put process water into the batching pot;
[0094] 2) Under stirring, slowly add the thickener, and after fully dispersed, adjust the pH to 6-9;
[0095] 3) Add component A, component B, potassiumion-containing auxiliary agent, alkaline auxiliary agent, and surfactant in sequence, and stir evenly;
[0096] 4) Put the essence into the batching pot and stir evenly;
[0097] 5) Add other additives into the batching pot and stir evenly;
[0098] 6) Pass the inspection and pack.
[0099] 250ppm hard water was used in the experiment to prepare according to the method of GB 9985-2000B1.2.
[0102] Into the beaker, add 1.0L 250ppm hard water, and 8g sample, stir to dissolve, put int...

[0141] 1. Purchased from BASF; 2. Purchased from Lubrizol.
[0142] The results show:
[0143] 1. Comparative example 1 without thickener not only cannot be stored stably at low temperature or high temperature, but its viscosity is also very small, so it cannot be applied to automatic dishwashers;
[0144] 2. Comparative Example 2, Comparative Example 3 and Comparative Example 4 show that although increasing the silicate content of the alkali additive can increase the viscosity of the product, it cannot be stored stably under high or low temperature conditions.
[0145] 3. Comparative example 2 and comparative example 5 show that although increasing the thickener content can increase the viscosity of the product and achieve stable storage under high temperature conditions, a large number of ice crystals will be precipitated unde...

Abstract
The invention relates to a liquid phosphorus-free detergent composition and application thereof. The liquid phosphorus-free detergent composition is prepared from the following components in percentage by weight: (i) 0.05 percent to 5 percent of potassium ions; (ii) 0.01 percent to 5 percent of a thickener; (iii) 0.1 percent to 40 percent of a component A; (iv) 0.1 percent to 10 percent of a component B; (v) 10 percent to 40 percent of an alkaline auxiliary agent; (vi) 0.01 percent to 10 percent of a surfactant; (vii) 20 percent to 85 percent of water, wherein the component A is selected from one or a mixture of more of a compound based on amino acid and salt thereof, a compound based on succinic acid and salt thereof and a polycarboxyl compound and salt thereof; the component B is selected from an anionic polymer and salt thereof. The liquid phosphorus-free detergent composition provided by the invention has excellent cleaning power and high stability and can be used for effectively inhibiting water scale from being formed.
Description
technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a liquid phosphorus-free detergent composition and its application. Background technique [0002] The emergence of dishwashers can meet consumers' high-level needs for healthy life and leisure time, and is more suitable for the high-paced life of modern families. In order to improve the cleaning power of the dishwasher, it is necessary to use detergent in combination, and the formulations include powder, liquid, block and formulations wrapped in water-soluble films. Generally, powder and block products use phosphorus-containing additives, strong alkaline additives and strong oxidants, which are easy to absorb moisture and agglomerate in a humid environment. This defect has been well known in the industry. Dosage forms wrapped in water-soluble films have high requirements for manufacturing processes, which limits their application. The liquid dosage form is widel...
