Does the effect of washing clothes have anything to do with the amount of washing powder? Washing powder can not only clean dirty clothes, but also clean floors, toilets, etc., and is widely used in life. When using washing powder, everyone thinks that the more foam the washing powder has, the stronger the decontamination ability. In fact, this idea is wrong. There are many misunderstandings of washing powder in daily use. Today, the editor will give you a detailed introduction: I think that the more foam the washing powder has, the better. In fact, the amount of foam is not directly related to the detergency. When washing clothes, the amount of washing powder should be added enough. When washing especially dirty clothes, it should be added more, but it is not that the more washing powder, the better. When the washing powder reaches a certain concentration and the surface activity of the aqueous solution reaches a larger value, the detergency will no longer increase with the increase of the washing powder, but will tend to decrease. When the concentration of washing powder is 0.2% to 0.5%, the surface activity of the aqueous solution is high, and the washing and decontamination ability is strong, that is to say, it is enough to add 5 to 10 grams (about 1 teaspoon) of washing powder to the clean water in a basin. . Excessive addition of washing powder will not only increase the decontamination effect, but also damage the clothes fibers due to the increase of alkalinity in the solution. In addition, a large amount of washing powder is attached to the clothes, which has a lot of foam, which is not easy to be rinsed, wastes water, takes time, and causes waste. The ingredients remaining on the clothes will also cause damage to the skin and cause allergic reactions.
