There is no doubt that the detergency of detergent is high in phosphorus!
The phosphorus in the washing powder is sodium tripolyphosphate, which is not only a water softener, but also a detergent in itself. It can emulsify, penetrate, puff, and expand various oil stains, and has a strong decontamination effect. Its water softening function can reduce the consumption of surfactants, which is equivalent to increasing the dosage of main washing ingredients. It can be said that without sodium tripolyphosphate, there would not be today's laundry detergent - more than 100 years ago, the German Henkel Company produced synthetic laundry detergent for the first time in the world, and the ingredients in the formula exceeding 35 were all Sodium tripolyphosphate.
Phosphorus-free laundry detergent is a new type of laundry detergent developed to reduce the eutrophication of water bodies by phosphorus. It should be noted that phosphorus-containing laundry detergent is not poisonous and harmful to pollute the water body, but the phosphorus in it is one of the main nutrients for biological growth. Excessive phosphorus content will lead to eutrophication of the water body, which is over-fertilization, not It's poisonous, and it won't hurt your hands! Therefore, for the phosphorus-poor areas in the northwest, some experts also call for the ban on phosphorus-containing washing powder to make up for the insufficient phosphate fertilizer content in the area.
