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.

2. Can the washing powder be mixed with the disinfectant? (No)

Many housewives like to add disinfectant when washing clothes with detergent. But this kind of laundry method can just make the cleaning and disinfection effect greatly reduced.

The composition of the washing powder is different, anionic, cationic or non-ionic, as is the disinfectant. If the washing powder is mixed with the disinfectant, it is easy to produce a neutral reaction, and the respective effects will be weakened.

Most of the disinfectant is used to eliminate pathogenic microbial contamination, unless under special conditions, such as red eye disease, diarrhea, onychomycosis, scalp spasm, etc., or women during menstruation, puerperium and infancy, there is no need to use disinfectant clothes. Because people have certain resistance, a small amount of non-pathogenic microorganisms will not pose a health threat. After washing and drying the clothes, after sufficient sunlight, the bacteria remaining on the clothes will be self-reliant after reaching a certain time. Perish. The frequent use of disinfectant not only reduces the body's own resistance, but also easily causes liver damage.

3. Is the multi-functional washing powder better? (No)

Many washing powders on the market now add some new ingredients and have more and more washing functions. These ingredients mainly include surfactants, builders, stabilizers, brighteners, essences and enzymes to achieve the purpose of being easy to dissolve, clean, soften, foam, and prevent static electricity. But there are more substances added to the washing powder, which is not a good thing for our health.

Studies have shown that commonly used builders have damage to the human liver; surfactants have long been found to damage the stratum corneum of the skin, causing rough skin, which is now considered a major public hazard to pollute the environment; In addition to absorbing water, the alkaline substance can also destroy the cell membrane of the human body and denature the tissue protein. The synthetic flavor in the fragrant washing powder is too much, and the odor is rushing, which often causes allergies in some people; Organochlorine and fluorescent agents are toxic substances that are easily accumulated in the human body and cause damage to health.

Therefore, the purchase of washing powder should be as simple as possible, with less added ingredients and lighter smell. From an environmental point of view, it is best to choose a non-phosphorus detergent that has little water pollution.

4. Put the clothes and then put the water and washing powder in the laundry? (No)

Many people are used to storing dirty clothes in the washing machine, and then put water and washing powder in the laundry. In fact, when washing the laundry, you should put the washing powder first. Because it is a powder, it is not easy to dissolve. It should be used before it can be used to better exert its effect, so as to avoid rinsing and leaving residue. The correct method is: first dissolve the washing powder in water, then put it into the laundry, soak it for 10 minutes before cleaning.

5. The higher the amount of washing powder, the cleaner the clothes are washed? (No)

The amount of organic washing and hand washing is printed on the washing powder package currently sold. In the laundry, the detergent should be placed in an appropriate amount according to the standard. When the amount of detergent exceeds the standard, the excess detergent can not only increase the detergency, but is easy to remain on the clothes, is not easy to clean, and also irritates the skin. If the detergent contains bleaching effect, excessive use will cause the clothes to fade and damage.

6. When the clothes are washed, the higher the temperature, the better? (No)

The water temperature for washing clothes is not as hot as possible. We use a variety of enzyme-containing detergents, the enzymes of which mainly include alkaline proteases and alkaline lipases.

Alkaline proteases are used to break down proteinaceous stains such as perspiration and blood stains. Alkaline lipase acts mainly on fatty acids and their esters, which is what we usually refer to as oils. 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, the solubility is significantly reduced, and the coagulation of the egg after cooking is an example. One of the conditions that cause degeneration is high temperature. This is also the case with protein stains on clothing. Therefore, if the water temperature is too high during washing, they will denature and solidify on the fabric fibers, making it more difficult to wash.

7. Is it appropriate to take laundry detergent in hand laundry? (No)

After long-term direct contact with alkaline washing powder, 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 lead to itching of the skin, and even cause symptoms such as atopic dermatitis or leave pigment on the skin. calm. So don't wash your hair with detergent or long-term contact with the skin. If you wash your hands, it is best to use soap.

8. Is it necessary to wash the clothes and leave a little foam? (No)

The current washing products seem to be "efficient", obviously used as little as possible, and each time the clothes are washed, there is always a lot of foam left on the drum wall of the washing machine. Or when it is hand laundry, it has been rinsed five or six times, and there are still a lot of "small bubbles" on the water. Doesn't it matter?

Experts pointed out that it is not necessary to leave a small amount of foam, it should be within the scope of safety. In the case that the amount of washing powder is generally suitable, the normal washing program set by the fully automatic washing machine can completely rinse the clothes. If it is hand washing, it can be rinsed two or three times. Consumers can choose high foam and low foam detergents according to their own habits. No matter which kind of laundry product is chosen, the user feels that it can be washed, convenient, and easy to rinse, which means that the user is accustomed to and feels comfortable.

9. Does the washing powder have a shelf life? (No)

Washing powder cannot be used indefinitely. Ordinary washing powder can generally be stored for two years or more under the specified storage conditions. However, some detergents with special ingredients have a service life of less than two years.

In order to avoid the failure of washing powder, when storing washing powder, it should be protected from moisture and sun. It should be placed in a cool and dry place, especially with enzyme and fragrant washing powder. When the temperature is too high, the essence will volatilize and the enzyme will lose its activity. It is best to put it in a plastic bottle or jar with a lid. On the one hand, it avoids the moisture absorption and agglomeration of the washing powder, and on the other hand, it prevents the fragrance from being released and allows people to inhale more synthetic flavors.
