What is the use of washing powder? About raw
1. Is washing powder a "universal cleaner"? (No)
In life, there are indeed many people who use washing powder as a "universal cleaner". In addition to washing clothes, they also use it to wash fruits, vegetables, tableware, furniture, and floors, believing that it has the functions of decontamination, disinfection, and sterilization. Little do they know that this may cause washing powder to enter the human body. Experts warn that even if the amount of washing powder entering the body is very small, it can cause poisoning.
2. Can washing powder be mixed with disinfectant? (No)
Many housewives like to add some disinfectant when washing clothes with washing powder. But this laundry method may just make the cleaning and disinfection effect greatly reduced.
The ingredients of washing powder are different, anionic, cationic or non-ionic, and the same is true for disinfectants. If washing powder and disinfectant are mixed, it is easy to generate a neutralizing reaction, and their respective effects will be weakened.
Disinfectant is mostly used to eliminate the contamination of pathogenic microorganisms, unless under special conditions, such as someone in the family suffering from pink eye, diarrhea, onychomycosis, psoriasis, etc., or women's menstruation, puerperium and infancy, otherwise, there is no need to use disinfectant to wash clothes. Because people themselves have a certain resistance, a small amount of non-pathogenic microorganisms will not pose a threat to health. After washing and drying clothes after full sun exposure, the bacteria on the clothes will perish on their own after a certain period of time. And frequent use of disinfectant not only reduces the body's own resistance, but also easily causes liver damage.
3. Is the washing effect of multi-functional washing powder better? (No)
Nowadays, many washing powders on the market have added some new ingredients, which have more and stronger washing functions. These ingredients mainly include surfactants, builders, stabilizers, whitening agents, flavors and enzymes, etc., to achieve the purpose of being soluble, clean, softening, foaming, and preventing static electricity from clothes. But more substances added to washing powder are not good for our health.
Studies have shown that commonly used detergents can damage the human liver; while surfactants have long been found to damage the stratum corneum of the skin, causing rough skin, and are now regarded as a major public hazard in polluting the environment; strong, alkaline substances contained in washing powder can not only absorb water, but also destroy human cell membranes and denature tissue proteins; there are too many synthetic flavors in perfumed washing powder, and the smell is pungent, which often causes allergies in some people; the organic chlorine and fluorescent agents contained in whitening washing powder are toxic substances, which are easy to accumulate in the human body and cause damage to health.
Therefore, when purchasing washing powder, try to choose one that has simple functions, few added ingredients, and a light smell. From an environmental perspective, it is best to choose phosphorus-free washing powder that has little water pollution.
4. Do you put clothes first and then water and washing powder when doing laundry? (No)
Many people are used to storing dirty clothes in the washing machine, and then adding water and washing powder when washing. In fact, when cleaning laundry, you should put in washing powder first. Because it is a powder, it is not easy to dissolve, and it should be melted with water first to better exert its effect, so as not to rinse it uncleanly and cause residues. The correct way is to dissolve the washing powder in water first, then put it in the laundry, soak it for ten minutes and then wash it.
5. The greater the amount of washing powder, the cleaner the clothes will be? (No)
The washing powder packages sold now are printed with the dosage of machine washing and hand washing. When doing laundry, an appropriate amount of detergent should be added according to its standard. When the amount of detergent exceeds the standard, the excess detergent not only cannot increase the decontamination power, but is easy to remain on the clothes, which is not easy to wash, and can also irritate the skin. If the detergent contains bleaching effect, excessive use will make the clothes fade and damage.
6. Is the higher the water temperature when washing clothes, the better? (No)
The water temperature for washing clothes is not as hot as possible. We often use various enzyme-containing washing powders, among which the enzyme preparations mainly include alkaline protease and alkaline lipase.
Alkaline proteases are used to break down protein stains such as sweat and blood stains. Alkaline lipase mainly acts on fatty acids and their esters, which are what we usually refer to as oil stains. The activity of the two enzymes is related to temperature, and about 40 ° C is the most suitable. Too high or too low temperature will reduce the activity of the enzyme.
Secondly, proteins have a denaturing effect. Its distinctive feature is that proteins coagulate, and their solubility is significantly reduced. One of the conditions that cause denaturation is high temperature. The same is true for protein soils on clothing. Therefore, if the water temperature is too high during laundry, it will make them denatured and solidified on the fabric fibers, making it more difficult to wash.
7. Is it important to leave some foam after washing clothes? (No)
The current washing products seem to be very "efficient", and they have been used as little as possible, but every time the clothes are washed, there is always a lot of foam left on the drum wall of the washing machine. Or when you wash the clothes by hand, you rinse them five or six times, and there are still a lot of "small bubbles" stubbornly left on the water surface. Does this matter?
Experts point out that it doesn't matter if there is a small amount of foam left, it should be within a safe range. When the amount of washing powder is roughly appropriate, the normal washing procedure set by the fully automatic washing machine can completely rinse the clothes. If it is hand washing, rinse it thoroughly two or three times. Consumers can choose high-foam and low-foam detergents according to their own habits. No matter what kind of laundry product is used, it is subject to the user's own feeling that it can be washed, convenient, and easy to rinse, which means that the user's habits and feelings are smooth.
