First of all, the amount of foam is not the key factor that directly determines the decontamination effect. Many people think that the more foam, the stronger the decontamination ability, but this is not the case. The surfactant in the laundry detergent is the main component that plays a decontamination role. It reduces the surface tension of water and makes it easier for stains to be removed by water. The generation of foam is mainly due to the formation of surfactants under the action of stirring and water flow. Some efficient laundry detergents may have excellent decontamination effects even with low foam. For example, some low-foam laundry detergents designed specifically for washing machines, although they have less foam, can remove various stains in a shorter washing time.
Secondly, too much foam sometimes brings some problems. In a washing machine, if there is too much foam, it may cause overflow, which not only wastes water resources, but may also damage the washing machine. Moreover, too much foam makes it difficult for clothes to fully tumble during the washing process, affecting the decontamination effect. In addition, washing foam also requires more water, which increases the washing cost and the burden on the environment. For example, in some areas where water resources are scarce, using low-foam laundry detergent can better save water.
Moreover, different washing scenarios have different requirements for foam. When washing by hand, the right amount of foam can make people feel that the washing process is more intuitive and seems to have a better decontamination effect. But in fact, as long as you rub and soak it fully when washing by hand, even a laundry detergent with less foam can remove stains well. In industrial washing, low-foam or no-foam laundry detergents are usually selected to improve washing efficiency and reduce costs.
Finally, when choosing a laundry detergent, consumers should not judge the decontamination effect based solely on the amount of foam. The brand, ingredients, and scope of application of the laundry detergent should be considered comprehensively. At the same time, you can refer to the reviews of other users and the test results of professional organizations to choose a laundry detergent that suits your needs. In short, there is no necessary connection between the amount of foam in the washing powder and the decontamination effect. Consumers should look at the foam problem rationally and choose the right laundry detergent.
