Problems solved by technology

[0005] Therefore, the content of the main active substances (fatty alcohol polyoxyethylene ether ammonium sulfate and ammonium lauryl sulfate) of the washing liquid prepared by the traditional process is generally 10%-24%, and the content of the main active substances is relatively low. Most of the raw materials are powder, which is inconvenient for storage and processing

Embodiment 1

[0019] The preparation method of described washing concentrate is as follows:

[0020] First heat the water to 85°C, and keep the temperature not lower than 85°C, stir and dissolve ethylene glycol stearate and coconut oil monoethanolamide, then add 10Kg fatty alcohol polyoxyethylene ether ammonium sulfate, Stir for 5-15 minutes, then control the temperature between 50°C-60°C, let the above mixture stand for 1-2 hours, add ammonium chloride and stir for 5-10 minutes, add the remaining 40Kg between 45°C-50°C Fatty alcohol polyoxyethylene ether ammonium sulfate and ammonium lauryl sulfate, cocamidopropyl betaine, lauryl dimethylamine oxide, preservative, just stir well.

[0021] The appearance of the concentrated washing liquid is pearly milky white, crystal clear, has a strong pearlescent effect, and is a thick paste liquid. The concentrated washing solution can be directly diluted with water to prepare a washing solution. Recommended dosage The washing concentrate accounts fo...

Embodiment 2

[0023] The preparation method of described washing concentrate is as follows:

[0024] Firstly, the water is heated to 90° C., and the rest of the steps are the same as those described in Example 1. In addition, citric acid is added to adjust the pH value to 6-7 before adding the preservative. The prepared washing concentrated liquid is pearly milky white in appearance, crystal clear, has strong pearlescent effect, and is a thick paste liquid. Its method of use is the same as that described in Example 1.

Embodiment 3

[0026] The preparation method of described washing concentrate is as follows:

[0027] Firstly, the water is heated to 100° C., and the rest of the steps are the same as those described in Example 2. The prepared washing concentrated liquid is pearly milky white in appearance, crystal clear, has strong pearlescent effect, and is a thick paste liquid. Its method of use is the same as that described in Example 1.

Abstract

The present invention relates to a washing liquor and its preparation method, in particular, it relates to a washing concentrate and its preparation method. Said washing concetnrate is formed from the following raw material: (by wt%) 38.5-54.6% of fatty alcohol polyoxyethylene ether sulfate and lauryl sulfate, 0% or 3-6% of ethylene glycol distearate, 0-9% of coco alkanolamide, 0-7% of coco amide propylbetaine, 0-4% of dodecyl dimethyl amine oxide, 0-3% of inorganic salt, 0-1% of acidifying agent, 0-0.5% of preservative, 0-30% of water and impurity. Said invention also provides the concrete steps of its preparation method.

Description

Technical field: [0001] The invention relates to a washing liquid used for cleaning and sanitation in people's daily life and a preparation method thereof, in particular to a washing concentrated liquid and a preparation method thereof. Background technique: [0002] The washing liquid that people use for cleaning and sanitation mainly includes cleaning products such as shampoo, bath liquid, hand sanitizer, liquid hand soap, and facial cleanser. [0003] The traditional process of making washing liquid usually uses anionic surfactants such as fatty alcohol polyoxyethylene ether ammonium sulfate (AESA, active ingredient content 70%) and lauryl ammonium sulfate (K 12 A, active ingredient content 70%) is dissolved in water, then add other components such as pearl paste, coconut oil alkanolamide, betaine, amine oxide and other raw materials, and then adjust the viscosity. Or add a pearlescent agent such as ethylene glycol distearate to hot water (generally 70-80°C) to dissolve,...
