Of course, the thicker the laundry detergent, the better. Even "ultra-concentrated" laundry detergent is more expensive than ordinary laundry detergent. Therefore, at the same quotation level, people always choose laundry detergent that looks thicker.

This is a typical concept with the same appearance and different reality. The method to increase the unit detergency of laundry detergent is to increase the content of active ingredient surfactant. Laundry detergent containing 20% surfactant certainly looks thicker than detergent containing 10% surfactant and has better detergency. However, it is too decisive to say that laundry detergent that looks thicker must be very good. Anyone with a little knowledge knows that just adding some cheap thickeners can make the laundry detergent "too thick to melt", and chemical experts inform us that the cheapest thickener is NaCl, which is the salt we use for cooking every day, and it has almost no detergency.

At present, in foreign countries, some laundry detergent manufacturers even add a little "viscosity reducer" to the concentrated laundry detergent to "stir up chaos and cure"-it is well known that the thicker the laundry detergent looks, the better. the coolness makes the laundry detergent appear "thinner" and pour it out of the bottle, not more circulating?

When choosing laundry detergent, I attach great importance to whether it can have rich bubbles. If a bottle of laundry detergent is added and placed in hot water, there will be no bubbles at all, and my heart will doubt its detergency.

There is really no need to worry. Poor foaming does not mean poor detergency. These are two concepts. And you can be like knitwear, brushed skirt, cotton trousers and so on, they must love to wash "bubble bath"? Not necessarily, in the automatic washing machine into thousands of households today, Zhengzhou laundry detergent has become an important condition for smart housewives to buy laundry detergent and detergent, because easy to rinse means saving water and energy, very environmentally friendly!

I like to wear white clothes, and even bedding is mostly white. I have been looking for a colorless and bright laundry detergent, but to my disappointment, almost no laundry detergent does not take part in essence pigment. Most laundry detergent is light blue. I am very worried. Will my white shirt, white trousers and super-clean white pillowcase be ravaged into light blue by it?

This is also an unnecessary worry. Adding a few indigo pigments to the laundry detergent will not only cause damage to white clothes, but also make white clothes look whiter after washing and exposure. However, the principle of light reflection is mainly involved here and has nothing to do with chemistry. When using washing powder, I will be careful to wear rubber gloves before washing clothes. Using laundry detergent, I don't have this "vigilance". Recently, after using laundry detergent, I also feel itchy on my hands, and I am inevitably confused: Does laundry detergent also hurt my skin?

Of course, it cannot be said that all laundry detergent does not hurt clothes or hands, just as it cannot be said that all laundry detergent does not hurt clothes and hands. The real injury is the strong alkaline washing powder (pH over 8.5), also contains a part of the strong alkaline laundry detergent. Generally speaking, the pH value is between 7~7.5 neutral laundry detergent, mild temperament, not easy to make the fabric fade, but its value is low detergency. Therefore, neutral laundry detergent is suitable for washing light-scale clothes, such as clothes that need to be changed every day in summer, clothes that are pure natural and have poor color fixation ability such as wool, silk and linen.

When cleaning heavy-duty clothes, you can choose washing powder or liquid detergent with strong alkalinity, and remember to wear rubber gloves when soaking and cleaning.
