How to understand the poor decontamination ability of expensive laundry beads

There are many kinds of laundry beads in the market, and their prices will be high or low. Everyone knows that a price is paid for. However, many users understand the decontamination ability of expensive laundry beads. Relatively poor, how should we understand this phenomenon?

Professionals will give us a detailed explanation on this issue. The main raw material in the laundry gel beads is called surfactant, which is the key substance for decontamination. Theoretically, the more expensive the laundry beads, the higher the surfactant content, but in fact, this is not exactly the case. The laundry beads at three prices are taken to the Beijing Detergents Quality Monitoring Station for testing, through weighing, suction filtration, water bath evaporation, high temperature baking (105 ℃), room temperature cooling, and then through color titration, the test results As follows: the surfactant content of the 9-yuan laundry gel beads is 20.5, the surfactant content of the 11.2 yuan laundry gel beads is 17.1, and the surfactant content of the 16.09 yuan laundry gel beads is 14.3. On the contrary, the test results show that the more expensive the laundry gel beads, the lower the surfactant content. What is going on?

　　 said: 'Expensive laundry beads may be compounded and contain multiple surfactants, but only one can be detected. Expensive laundry beads contain not only surfactants, but also many additives and Additives, if there are too many ingredients in the laundry beads, the price is naturally expensive.' But it cannot be understood that the washing effect of expensive laundry beads is not good.
