Green phosphate-free laundry detergent powder, and preparation method thereof

Abstract

The invention belongs to the field of daily chemical industry, and relates to a green phosphorus-free washing powder and a preparation method thereof. It is made of the following raw materials in the following weight ratio: 10-30 parts of sodium alkylbenzene sulfonate, 10-30 parts of alkyl glycoside 20 parts, 10-30 parts of sodium percarbonate, 15-25 parts of anhydrous sodium sulfate, 5-10 parts of sodium carbonate, 3-8 parts of sodium silicate, 0.5-2 parts of sodium carboxymethyl cellulose, 1-5 parts of zeolite part, 0.1-0.3 part of fluorescent whitening agent, 0.2-0.4 part of protease, and 0-0.2 part of essence. drying, pulverizing and sieving to obtain the green phosphorus-free washing powder. The invention has the advantages of low cost and simple process, and the prepared washing powder has good hard water resistance, strong decontamination ability, rich foam, mild hand washing, clean and bright clothes after washing, and long-lasting fragrance. It adopts green and environmental protection formula, and the degradation rate of raw materials is high.

Description

technical field [0001] The invention belongs to the field of daily chemical industry and relates to a green phosphorus-free washing powder and a preparation method thereof. Background technique [0002] Washing powder is our daily necessities, and washing powder can be divided into phosphorus-containing washing powder and phosphorus-free washing powder. Washing powder needs to add additives to play a better role. Among them, the phosphorus-containing additive is sodium tripolyphosphate, which can effectively decompose the dirt in the clothes and thus clean the clothes. However, a large amount of phosphorus-containing detergents will cause water Eutrophication, thereby destroying water quality and polluting the environment. Laundry with phosphorus-containing laundry detergent also has a strong stimulating effect on the skin. Wearing the washed clothes on people will cause itching, and phosphorus elements will slowly enter the body and directly affect people to produce variou...

AI Technical Summary

Problems solved by technology

At present, the phosphorus-free laundry powder produced in the United States, Japan, Western Europe and other countries only uses benzenesulfonic acid, fatty acid, etc. as surfactants, and zeolite and sodium carbonate replace phosphate as chemical raw materials for decontamination. The effect is not good, the detergency is not strong

Phosphate-free laundry detergent we generally use, the main surfactant is sodium alkylbenzene sulfonate, its disadvantage is poor resistance to hard water, decontamination performance can be reduced with the hardness of water; It is irritating to a certain extent, and the clothes feel poor after washing

Phosphorus-free laundry detergent on the market today hurts hands, has a lot of foam, and is not easy to rinse off, which consumes water and time. The ingredients left on the clothes can also cause damage to the skin and cause allergic reactions, etc.
