Non-phosphor liquid laundry detergent

Abstract

A non-phosphorus liquid detergent for washing clothes is prepared from dodecylphenylsulfonic acid, urea, sodium hydroxide, emtrol polyoxyvinylether (OP-10), sodium benzoate, sodium citrate, glucose, fluorescent agent, essence, and water. Its advantages are low cost, no poison, less environmental pollution, no damage to clothes and human skin, high detergency and saving water by 75%.

Description

Technical field [0001] The invention relates to a detergent, in particular to a phosphorus-free liquid laundry detergent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of people's awareness of environmental protection, it has become an inevitable trend for washing products, especially laundry products, to be non-phosphating and pollution-free. At present, all countries in the world, especially developed countries, implement phosphorus-free detergents as mandatory standards. my country also began to enforce low-phosphorus washing powder a few years ago, encouraging the production and sales of phosphorus-free washing powder. But there is following major technical defect in the washing powder on the market at present: the one, alkaline is too strong, in order to pursue the effect and reduce production cost of stubborn dirt such as dirt, perspiration stain, greasy dirt, use sodium carbonate in...

Problems solved by technology

But there is following major technical defect in the washing powder on the market at present: the one, alkaline is too strong, in order to pursue the effect and reduce production cost of stubborn dirt such as dirt, perspiration stain, greasy dirt, use sodium carbonate in a large amount in washing powder, cause The activity of protease, the active ingredient in washing powder, is greatly reduced, which is not conducive to the cleaning of protein dirt. The washing effect is not as good as the original high-phosphorus washing powder. People often have to use soap or other detergents such as soap when cleaning the collar and cuffs of clothes. The collar is used to remove stubborn dirt. At the same time, the washing powder is too alkaline to cause great damage to the clothes and human skin, and the pollution of the washing sewage to the environment is still relatively serious. Second, in order to improve the washing effect, most washing powder still uses a small amount of phosphorous. Detergent additives such as sodium tripolyphosphate cannot truly be phosphating-free and continue to pollute the environment; third, in order to make the detergent powder puffed to have a certain weight and volume, a large amount of fillers such as sodium silicate are used in the detergent powder , Aluminum sulfate, Glauber's salt, most of the fillers do not have washing effect, but need a lot of water to rinse, which wastes both materials and water resources. After washing, the clothes will harden and feel bad. At the same time, these fillers are easily absorbed by the human body. Accumulation in the body can cause harm to human health
