Phosphorus-free washing powder refers to low-foaming washing powder without phosphorus P added. Phosphorus-free washing powder uses 4A zeolite and other phosphorus-free substances as builders, which reduces the discharge of phosphorus-containing sewage and is beneficial to the maintenance of the ecological environment.
The main reason is to prevent red tides because phosphorus can eutrophicate seawater and allow algae to grow. Phosphorus-free washing powder does not hurt the skin, does not pollute the environment, and most importantly, does not hurt the skin. Because of the low-foaming laundry detergent with phosphorus added, if the water after washing clothes flows into ponds, lakes, rivers, etc., it will cause the rapid growth of aquatic algae such as aquatic plants in it.
In the growth process of aquatic plants, there is respiration, which requires oxygen consumption, resulting in a great reduction in the amount of dissolved oxygen in the water, causing some animals and plankton in the water to die due to lack of oxygen, resulting in the destruction of the water environment and ecological imbalance. Even the diversity of species is reduced. This is the reason why phosphorus-containing low-foaming laundry detergent is not recommended. In the past, sodium tripolyphosphate (phosphorus-containing) was used in washing powder, but now LBD-1 dispersant (phosphorus-free) is used.
What are the types of synthetic laundry detergents in the low foam laundry detergent product?
Do you know the main ingredients of low foam laundry detergent products? The role of synthetic laundry detergent technology products in low-foaming laundry detergent products is mainly composed of nominal active agents (active substances), as the nominal active agents used in cotton and linen fabrics, which are mainly sodium alkyl benzene sulfonate and sodium fatty alcohol sulfate. The washing machine prepared by mixing the two has better performance. This low-foaming washing powder technology product can be mixed with a part of sodium alkyl benzene sulfonate or sodium secondary alkyl sulfate to increase the synergistic effect of the active substances. In addition to the important components in the formula, there are many components that help.
The auxiliaries used in the synthesis of low-foaming washing powder products such as phosphate (mainly sodium tripolyphosphate), silicate (water glass,) soda ash, sodium sulfate (glauber's salt), borax, zeolite and other inorganic auxiliaries, also There are chelating agents (such as NTA, EDTA, etc.), carboxymethyl cellulose (CMC), foam firming agents (alkyl alcohol amides, etc.), fluorescent whitening agents, slurry regulators (such as sodium methanesulfonate, xylenesulfonic acid, etc.) Sodium, etc.), enzyme preparations, flavors, pigments and other organic auxiliaries.
