Embodiment 1

[0059] The mass percent of raw materials used in this embodiment is dodecylbenzenesulfonic acid 13, fatty alcohol polyoxyethylene ether 8, polyacrylic acid sodium salt 3, potassium cocoate (KC30) 4, sodium hydroxide 2, ethylenediaminetetra Acetic acid 0.1, sodium chloride 1.4, sunscreen 0.3, preservative 0.7 and essence 0.3.

[0060] The preparation method of low-foaming easy-to-bleach antibacterial laundry detergent is:

[0061] (1) Prepare dodecylbenzenesulfonic acid, fatty alcohol polyoxyethylene ether, polyacrylic acid sodium salt, potassium cocoate, sodium hydroxide, ethylenediaminetetraacetic acid, sodium chloride, sunscreen, and preservatives according to the ratio , essence and water; the water is deionized water.

[0062] (2) Add water to the batching kettle, add chelating agent and sodium hydroxide, start stirring, heat to 40°C, add dodecylbenzenesulfonic acid, make the pH value 9;

[0063] This step guarantees the pH value so that the laundry liquid prepared by th...

Embodiment 2

[0072] The kind of raw material of embodiment 2 is exactly the same as that of embodiment 1, and difference only is that raw material consumption is different. The raw material percentage of embodiment 2 is as shown in table 2 namely dodecylbenzenesulfonic acid 10, fatty alcohol polyoxyethylene ether 9, polyacrylic acid sodium salt 5, lauryl potassium soap 3, sodium hydroxide 1.5, ethylenediaminetetra Acetic acid 0.3, sodium chloride 1.6, sunscreen agent 0.5, preservative 0.2 and essence 0.3.

[0073] The preparation method of low-foaming easy-to-bleach antibacterial laundry detergent is:

[0074] (1) Prepare dodecylbenzenesulfonic acid, fatty alcohol polyoxyethylene ether, polyacrylic acid sodium salt, lauryl potassium soap, sodium hydroxide, ethylenediaminetetraacetic acid, sodium chloride, sunscreen, preservative according to the ratio , essence and water;

[0075] (2) Add water to the batching kettle, add chelating agent and sodium hydroxide, start stirring, heat to 30°C...

Embodiment 3

[0085]The difference between embodiment 3 and embodiment 2 is that the raw materials do not include a sunscreen agent, and the amount of each raw material is different. The raw material percentage of embodiment 3 is as shown in table 2 namely dodecylbenzenesulfonic acid 11, fatty alcohol polyoxyethylene ether 10, polyacrylic acid sodium salt 1, oleic acid potassium soap 2, sodium hydroxide 1.5, ethylenediaminetetra Acetic acid 0.5, sodium chloride 1.6, preservative 0.1 and essence 0.3.

[0086] The preparation method of the low-foaming and easy-to-bleach antibacterial laundry detergent is similar to the preparation method of Example 1, lacking a sunscreen, and the mass percentages of raw materials are different in addition:

[0087] (1) Prepare dodecylbenzenesulfonic acid, fatty alcohol polyoxyethylene ether, polyacrylic acid sodium salt, potassium oleate soap, sodium hydroxide, ethylenediaminetetraacetic acid, sodium chloride, preservatives, essence and water;

[0088] (2) ...

Abstract

The invention discloses a low-foam easily-bleached degerming laundry detergent and a preparation method thereof, and belongs to the technical field of mixtures of non-ionic compounds and anionic compounds. The low-foam easy-to-bleach degerming laundry detergent is prepared from the following raw materials in percentage by mass: 10-15% of dodecylbenzene sulfonic acid, 5%-10% of fatty alcohol-polyoxyethylene ether, 1%-5% of a water-based high-molecular polymer, 1%-5% of potassium soap, 1%-2% of sodium hydroxide, 0%-0.5% of a chelating agent, 1%-2% of sodium chloride, 0%-0.5% of a preservative, 0.3% of essence and the balance of water. The preparation method comprises the following steps: preparing the dodecylbenzene sulfonic acid, the fatty alcohol-polyoxyethylene ether, the water-based high-molecular polymer, the potassium soap, the sodium hydroxide, the chelating agent, the sodium chloride, the preservative, the essence and the water in proportion, adding water into a batching kettle,adding sodium hydroxide, then adding dodecylbenzene sulfonic acid to enable the pH value to be 8.5-9.5, adding fatty alcohol-polyoxyethylene ether, sodium polyacrylate and potassium soap, adjusting the pH value to 8.0-10.0 and carrying out cooling and standing. The laundry detergent disclosed by the invention has the effects of low foam, easiness in bleaching and sterilization.

Description

technical field [0001] The invention relates to the technical field of mixtures of nonionic compounds and anionic compounds, in particular to a low-foaming and easy-rinsing sterilizing laundry liquid and a preparation method thereof. Background technique [0002] In daily life and work, people inevitably come into contact with various dirt. Washing is the process of removing unnecessary components from the object to be washed, that is, removing dirt from the surface of the object to be washed. The attachment relationship between dirt and washing objects includes physical adhesion and chemical adhesion. The force between physically attached dirt and washing objects is weak and easy to remove, such as sediment, fine powder, etc.; chemical adhesion is the formation of dirt through chemical reactions. The chemical bond is attached to the washing object, and the force between the chemically attached dirt and the washing object is strong, and the dirt is not easy to remove. [0...
