Preferably, the mass ratio of the fatty acid methyl ester ethoxylate to the isomeric fatty alcohol-polyoxyethylene ether is 1 (1-3).
Because the fatty acid methyl ester ethoxylate (FMEE) and the isomeric fatty alcohol-polyoxyethylene ether (CA-60) do not generate a gel phenomenon, and the liquid crystal gel zone of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) and the fatty alcohol-polyoxyethylene ether (AEO-9) can be effectively destroyed through the combined action of the fatty acid methyl ester ethoxylate (FMEE), the isomeric fatty alcohol-polyoxyethylene ether (CA-60) and 2-methyl-2, 4-pentanediol, the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) and the fatty alcohol-polyoxyethylene ether (AEO-9) are instantly dissolved in water and are rapidly dissolved in the process of blending, and the problems that the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) is slowly dissolved and the fatty alcohol-polyoxyethylene ether (AEO-9) is gelatinized in the blending process are well solved, when the mass ratio of the fatty acid methyl ester ethoxylate (FMEE) to the isomeric fatty alcohol-polyoxyethylene ether (CA-60) is 1 (1-3), the compounding effect of the fatty acid methyl ester ethoxylate (FMEE) and the isomeric fatty alcohol-polyoxyethylene ether (CA-60) is the best, the detergency of the high-concentration laundry detergent is strong, and the dissolving speeds of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) and the fatty alcohol-polyoxyethylene ether (AEO-9) in the batching process are higher.

Preferably, the potassium cocoate is obtained by neutralizing coconut oil acid and potassium hydroxide.
Because the active matter content of the prior potassium cocoate is lower, generally about 30 percent, when the active matter content of the added potassium cocoate is limited, if the conventional potassium cocoate is directly used as a raw material, more potassium cocoate needs to be added, the water proportion is easily extruded at the moment, so that other materials are difficult to dissolve, the potassium cocoate is obtained by neutralizing the potassium cocoate and potassium hydroxide, the dissolution performance of the raw material in the formula is not influenced, the potassium cocoate and calcium, magnesium and other ions in tap water generate water-insoluble calcium and magnesium soaps in the washing process, the gas of foam is damaged, the purposes of quick defoaming and improving the bleaching performance are achieved, the prepared high-concentration laundry detergent is used for rinsing clothes, only a small amount of foam is generated in the washing process, and the first rinsing is basically carried out without foam, the rinsing performance is excellent.
Preferably, the amount of the fatty alcohol-polyoxyethylene ether accounts for 20-30% of the total amount of the raw materials by mass percent;
the usage amount of the sodium fatty alcohol-polyoxyethylene ether sulfate accounts for 10-15% of the total usage amount of the raw materials according to mass percentage.
The fatty alcohol-polyoxyethylene ether (AEO-9) can be gelled when meeting water, when the using amount of the fatty alcohol-polyoxyethylene ether (AEO-9) is small, the fatty alcohol-polyoxyethylene ether can be dissolved for the second time under the mechanical action of stirring, and if the using amount of the fatty alcohol-polyoxyethylene ether (AEO-9) is too large, an irreversible gel can be formed, so that the dosing process and the service performance of the high-concentration laundry detergent are influenced;
the appearance of the sodium Alcohol Ether Sulphate (AES) is similar to slurry fluid, and has good solubility, but the dissolution speed is slow, so that the key link for restricting the production efficiency of the liquid detergent is realized, and if too much sodium Alcohol Ether Sulphate (AES) is added in the dosing process of the high-concentration laundry detergent, the sodium Alcohol Ether Sulphate (AES) can enter a gel zone and cannot be dissolved continuously, so that the dosing process and the service performance of the high-concentration laundry detergent are influenced.
The preparation method of the high-concentration laundry detergent without gel and precipitation comprises the following steps:
A. weighing anionic surfactant, nonionic surfactant, 2-methyl-2, 4-pentanediol, enzyme preparation, essence, preservative and water according to the formula ratio;
B. adding 2-methyl-2, 4-pentanediol, fatty acid methyl ester ethoxylate and isomeric fatty alcohol polyoxyethylene ether into water with the formula amount, uniformly stirring, then adding a nonionic surfactant, uniformly stirring, adding an anionic surfactant, and uniformly stirring;
C. and (3) selectively adding an enzyme preparation, essence and a preservative, and uniformly stirring to obtain the high-concentration laundry detergent without gel and precipitation.
The problem of gel of the fatty alcohol-polyoxyethylene ether (AEO-9) in the process of proportioning and the problem of slow dissolving speed of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) are solved by introducing the 2-methyl-2, 4-pentanediol and compounding the fatty acid methyl ester ethoxylate (FMEE) and the isomeric fatty alcohol-polyoxyethylene ether (CA-60), the content of active substances of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) is about 70 percent generally, the appearance of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) is similar to slurry fluid, the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) has good solubility, but the dissolving speed is slow, and is a key link for restricting the production efficiency of a liquid detergent, at present, the problem of slow dissolving speed of the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) is solved by configuring a pre-dissolving pot to dilute in advance or additionally arranging a high-speed shearing homogenizing, according to the invention, a system formed by water, fatty acid methyl ester ethoxylate (FMEE), isomeric fatty alcohol-polyoxyethylene ether (CA-60), 2-methyl-2, 4-pentanediol and fatty alcohol-polyoxyethylene ether (AEO-9) is added with the fatty alcohol-polyoxyethylene ether sodium sulfate (AES), and the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) can be dissolved in a pot by conventional stirring, so that the fatty alcohol-polyoxyethylene ether sodium sulfate (AES) can be dissolved immediately after being prepared in the material preparation process, the preparation efficiency is high, the preparation method is simple, the production efficiency is effectively improved, the production cost is reduced, and the application prospect is good.
