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

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 a detergent, in particular to a preparation method of soap nuggets. Background technique [0002] Soap has the advantages of natural, safe, good decontamination performance, good biodegradability and suitable for hand washing. It conforms to the trend of "returning to nature", which cannot be replaced by synthetic detergents. However, with the improvement of people's consumption level, ordinary soap has the following shortcomings: 1) It has poor resistance to hard water, and washing in hard water will interact with Ca 2+ , Mg 2+ It produces calcium-magnesium metal soap that is insoluble in water and has no washing ability, so that a large amount of soap loses its washing ability, causing waste, and the generated metal soap will mix with dirt to form soap dirt, which will be adsorbed on the fabric and container to be washed. The fabric is difficult to rinse and has yellowing, stiffness, brittleness, and densit...
