Problems solved by technology

Yet along with the raising of people's consumption level, common soap has following shortcoming but: 1) anti-hard water property is poor, washes in hard water and Ca 2+ , Mg 2+ Calcium-magnesium metal soaps that are insoluble in water and have no washing ability are produced, causing a large amount of soap to lose washing ability, resulting in waste, and the generated metal soap will mix with dirt to form soap scum, which is adsorbed on the fabrics and containers to be washed. The fabric is difficult to rinse, yellow, hard, brittle, and density is reduced; 3) The solubility in cold water is poor, which affects its detergency
However, after adding about 5% (or more) of MES after this process, it is difficult to ensure the uniformity of mixing, that is, the white powdery MES precipitation phenomenon begins to appear in a certain period of time.
At the same time, since ordinary soaps are mostly free alkali, the presence of free alkali and soap moisture makes MES easier to hydrolyze into disodium salt, which reduces the decontamination and use performance to a certain extent

[0093] Sodium chloride: 0.35%,

[0094] Glycerin: 0.35%,

[0095] EDTA-4Na: 0.044%,

[0096] HEDP-4Na: 0.044%

example 1

[0097] Fatty acid (C12 and C14 mixture) and fatty acid (C16 and C18 mixture) ratio 1:4

[0098] Soap particle preparation process steps:

[0099] as attached figure 1 It shows that sodium chloride, EDTA-4Na, HEDP-4Na, and glycerin are pre-dissolved in water, and then configured into brine and poured into the storage tank, and the fatty acid (C12 and C14 mixture), fatty acid (C16 and C18 mixture), , glycerin, MES prepared as a solution, water, sodium chloride, EDTA-4Na, HEDP-4Na are pumped in through a flow pump, mixed and reacted through a mixer, then dried and formed in a vacuum spray dryer, and then squeezed out of soap through a refiner grain. Soap granules are prepared into soap bars through a soap forming line.

Abstract

The invention provides a preparation method of soap grain and laundry soap.The preparation method includes: mixing raw materials such as fatty acid, glycerin, alkali and MED in the presence of water, performing spraying drying on the obtained mixture, and preparing the soap grain.The laundry soap prepared by the soap grain is good in stability, high in cleaning power and high in hard water resistance.

Description

technical field [0001] The invention relates to a preparation method of detergent, in particular to a preparation method of soap grains. Background technique [0002] Soap has the advantages of being natural, safe, good decontamination performance, good biodegradation performance and suitable for hand washing, conforming to the trend of "returning to nature", which cannot be replaced by synthetic detergents. Yet along with the raising of people's consumption level, common soap has following shortcoming but: 1) anti-hard water property is poor, washes in hard water and Ca 2+ , Mg 2+ Calcium-magnesium metal soaps that are insoluble in water and have no washing ability are produced, causing a large amount of soap to lose washing ability, resulting in waste, and the generated metal soap will mix with dirt to form soap scum, which is adsorbed on the fabrics and containers to be washed. The fabric is difficult to rinse, yellowing, hard, brittle, and density is reduced; 3) The so...
