Embodiment 1-5

[0030] Embodiment 1-5 is a kind of washing powder containing α-sulfo fatty acid alkyl ester salt of the present invention and the embodiment of preparation method thereof, the component and each group of washing powder containing α-sulfo fatty acid alkyl ester salt The mass percent content of the points is shown in Table 1.

[0031] Table 1 contains the formula of the washing powder of α-sulfo fatty acid alkyl ester salt

[0032]

[0033] Embodiment 1-5 preparation steps are as follows:

[0034] (1) Slurry preparation and spray drying: Add a set amount of process water into the batching kettle, heat to 60°C, then add anionic surfactants and various detergent additives in sequence, stir and dissolve while adding materials, and then add pH The regulator adjusts the pH of the slurry to 7.5, and finally adds α-sulfo fatty acid alkyl ester salt. After stirring evenly, the mass concentration of the slurry is controlled at 60-75%, and the spray drying of the slurry is completed w...

Abstract

The invention relates to washing powder containing alpha-sulfofatty acid alkyl ester salt and a preparation method thereof. The washing powder containing alpha-sulfofatty acid alkyl ester salt is prepared from the following raw materials in percentage by mass: 1.0 to 20.0 percent of alpha-sulfofatty acid alkyl ester salt, 1.0 to 12.0 percent of nonionic surfactants, 1.0 to 30.0 percent of anionicsurfactants, 1.0 to 10.0 percent of anticaking agents, 10.0 to 85.0 percent of washing auxiliary agents and 0.5 to 20.0 percent of pH regulators. The washing powder has the advantages that the material slurry is a neutral formula; the material preparation temperature, the material adding sequence, and the material slurry pH in the material slurry preparation process and spray drying process, and the tower entering and exiting temperature in the spray drying process are controlled, so that the washing powder containing alpha-sulfofatty acid alkyl ester salt has the advantages that the production process is simple; the anti-agglomeration performance is good; the stability of the alpha-sulfofatty acid alkyl ester salt in the washing powder is high.

Description

technical field [0001] The invention relates to the technical field of daily chemical cleaning products, in particular to a washing powder containing α-sulfo fatty acid alkyl ester salt and a preparation method thereof. Background technique [0002] With the rapid consumption of petroleum resources and the increasing awareness of environmental protection, renewable and green and healthy surfactants are becoming more and more popular in washing products. α-sulfo fatty acid alkyl ester salt (MES) is a product obtained from natural renewable raw materials, such as coconut oil, palm oil and other oil raw materials after sulfonation and neutralization. It is a kind of surfactant with good performance. Excellent calcium soap dispersibility, low irritation and good biodegradability, compared with the currently used surfactants, it has considerable advantages in cost performance, and has environmental protection significance. It is used to replace petroleum by-product alkylbenzene s...
