Will you use the washing powder correctly?

Do you like to wash your clothes with hot water? Always wash clothes with detergent? Brush the floor with detergent? Washing powder prefers "multi-function"? If you think so, then it’s all wrong!

Flavored washing powder is not good

Discrimination: Correct

Most people who buy detergents consider "whether it is clean or not". The second consideration is "whether the smell is good." However, most spices are synthetic, and 95% of their chemical composition comes from petroleum, such as benzene and aldehydes, which can cause cancer and cause reproductive disorders, but more commonly cause allergic dermatitis.

Hand laundry without detergent

Discrimination: Correct

After the skin is directly exposed to alkaline washing powder for a long time, the weak acid environment on the surface of the skin will be destroyed, and the effect of inhibiting the growth of bacteria will also disappear, which may easily cause itching of the skin, or even cause symptoms such as atopic dermatitis, or leave on the skin. Pigmentation. So when using hand laundry, it is best to use soap.

Washing powder can be used in one powder

Discrimination: Error

In life, many people regard washing powder as a "universal cleaning agent". In addition to washing clothes, they also use it to scrub furniture and floors, and think it has the function of decontamination, disinfection and sterilization. As everyone knows, this may cause the washing powder to enter the human body. Experts remind that even if the amount of detergent entering the body is very small, it will cause poison.

The effect of multi-functional detergent is good.

Discrimination: Error

Many washing powder advertisements have advertised the addition of some new ingredients, with more and more powerful washing functions. But there are more substances added to the washing powder, which is not a good thing for our health. Commonly used builders have been damaged by human liver, and surfactants have long been found to damage the stratum corneum of the skin, causing rough skin. Now it has been regarded as a major pollution of the environment: the alkali contained in strong washing powder In addition to absorbing water, sex substances can destroy human cell membranes and denature tissue proteins.

Washing powder and disinfectant are close partners

Discrimination: Error

Many housewives are used to adding disinfectant to remove bacteria when washing clothes. Some people simply put detergent and disinfectant into the washing machine at the same time. In fact, this will not only have no bactericidal effect, but also harm people's health.

Disinfectants are chlorine-containing phenolic disinfectants, and excessive or incorrect use can be dangerous. The washing powder contains a lot of surfactants. If the washing powder and the disinfecting solution are mixed, the chemical reaction is easy to occur, and the respective effects are weakened. In addition, if a chlorine-containing disinfectant is mixed with an acid-containing detergent, chlorine gas is generated. When the concentration of chlorine gas is too high, it will irritate the eyes, nose, throat and other organs. In severe cases, it will damage people's heart and lung tissues and even endanger life.

Washing powder also has a shelf life

Discrimination: Correct

Ordinary washing powder can generally be stored for about two years under the specified storage conditions, and washing powder with special ingredients may be used for less than two years. When storing the washing powder, it is best to put it in a plastic bottle or jar with a lid. On the one hand, it can avoid the moisture absorption and agglomeration of the washing powder, and on the other hand, it can prevent people from inhaling more synthetic flavor after the fragrance is emitted.

Washing clothes with hot water is cleaner

Discrimination: Error

The water temperature for washing clothes is not as high as possible. Because we use a variety of enzyme-containing washing powder, the enzyme preparations are mainly alkaline protease and alkaline lipase. Alkaline protease is used to decompose proteinaceous dirt, such as perspiration, blood stains, etc.; alkaline lipase is mainly used for fatty acids and their esters, which is what we usually refer to as oil stains. The activity of the two enzymes is temperature dependent and approximately 40 ° C is most suitable. Too high or too low temperature will reduce the activity of the enzyme. Second, the protein has a denaturing effect. Its remarkable feature is that the protein is coagulated and the solubility is significantly reduced. If the water temperature is too high during washing, the protein on the dirty clothes will be denatured and solidified on the fabric fibers, making it more difficult to wash.
