Problems solved by technology

However, if the non-phosphorus laundry detergent we use at present dissolves quickly, the detergency will be weak, and if the detergency is strong, the dissolution will be slow. It is poor resistance to hard water, and the washing effect is affected by the hardness of the water quality. The harder the water quality, the worse the decontamination effect. In addition, the non-phosphorus washing powder on the market hurts hands, has a lot of foam, and is not easy to rinse, which consumes water and time. Not to mention waste, the ingredients left on the clothes can also cause damage to the skin, cause allergic reactions, etc.

Abstract

The invention discloses a phosphate-free washing powder which is mainly prepared from the following raw materials in parts by weight: 430-455 parts of sodium carbonate, 190-220 parts of 4A zeolite, 95-115 parts of glauber salt, 238-260 parts of fatty alcohol polyethenoxy ether sodium sulfate, 2-4 parts of proteinase and 1-2 parts of essence. The production method of the phosphate-free washing powder comprises the following steps: evenly mixing sodium carbonate, 4A zeolite and glauber salt in a roller; directly adding fatty alcohol polyethenoxy ether sodium sulfate into the roller, and stirring for agglomeration and molding; and finally, adding proteinase and essence into the roller, and evenly mixing to obtain the phosphate-free washing powder. The phosphate-free washing powder has the advantages of high dissolution speed, strong detergent power, favorable biodegradability and high degradability (99%), can not hurt the skin due to mild detergency, and is free from the influence of water hardness due to favorable hard water resistance.

Description

technical field [0001] The invention relates to a washing powder, in particular to a phosphorus-free washing powder. Background technique [0002] Washing powder is our daily necessities. Washing powder is divided into phosphorus-containing washing powder and phosphorus-free washing powder. Phosphorus-containing washing powder uses phosphate as the main auxiliary agent, and phosphorus is easy to cause eutrophication of environmental water bodies, thereby destroying water quality. polluted environment. Phosphorus-free washing powder does not have this shortcoming, which is beneficial to the protection of the water body environment. For the health of our living environment, it is recommended to use phosphorus-free washing powder. However, if the non-phosphorus laundry detergent we use at present dissolves quickly, the detergency will be weak, and if the detergency is strong, the dissolution will be slow. It is poor resistance to hard water, and the washing effect is affecte...
