Some misunderstandings about using laundry detergent for home use
Some misunderstandings about using laundry detergent for home use
The more laundry detergent is used, the cleaner the clothes are
Many people think that the more laundry detergent is put, the cleaner the clothes are. In fact, this is a wrong concept, because when the detergent content in the water reaches saturation, the excess detergent cannot increase the cleaning power. Because too much washing powder will accumulate in the clothes and washing machine and cannot dissolve, and sewage will also damage the environment after being discharged. To use detergent efficiently and conservatively, the appropriate amount must be taken according to the amount of water used during laundry. Generally, only 6 grams of laundry detergent is needed to add 2 liters of water. Add 1 tablespoon of washing powder to most of the basin of water. At this time, the concentration of washing powder is between 0.3% and 0.5%. This ratio has the best decontamination effect and the strongest surfactivity.
Dressing detergent and soap
Some people see that the collar cuffs are too dirty when washing clothes with laundry, and like to apply soap, thinking that this will increase the ability to remove dirt. In fact, this is wrong. Because washing powder is weakly acidic and soap is weakly alkaline, both are used together and acid-base neutralizes, and the effects of both are weakened, and the decontamination effect is actually reduced. The correct way is to use only one middle detergent and increase the dosage at the collar, cuffs, etc.
Washing powder removes oil stains
The main ingredient of washing powder is sodium alkylphenate. After invading the human body, it will greatly inhibit the activity of amylase, trypsin, and pepsin in the human body, which can easily cause mild poisoning in the human body. Laundry powder also contains a variety of elements such as phosphorus, which also has different degrees of harmful effects on the human body. If washing detergent is used frequently to clean dishware, it will have an adverse impact on human health. Therefore, washing detergent cannot be used to wash tableware.
The more foam, the stronger the detergent force.
The more foam, the better the more laundry detergent foam. In fact, there is no direct connection between the amount of foam and the detergent force. When washing clothes, the amount of washing powder should be added in sufficient amount. It is appropriate to add more when washing particularly dirty clothes, but the more washing powder you add, the better. When the washing powder reaches a certain concentration and the surface activity of the aqueous solution reaches the maximum, the detergent force will no longer increase with the increase of the washing powder, but will tend to decrease. Practice has proved that when the concentration of washing powder is 0.2% to 0.5%, the aqueous solution has the highest surfactivity and the strongest washing and detergent ability. That is to say, adding 5 to 10 grams (about 1 teaspoon) of washing powder to the clean water in a basin is enough. In addition to adding excessive washing powder, it will not increase the detergent effect, but will also damage the fibers of the clothes due to the increase in alkalinity in the solution. In addition, a large amount of washing powder is attached to clothes, which has a lot of foam and is not easy to rinse, which consumes water and time, causing waste, not only the ingredients remaining on clothes will also cause damage to the skin, causing allergic reactions, etc.
White enhancement means cleanness
Many washing powder and detergent products have added fluorescent whitening agents to make the clothes look translucent and clean after cleaning, and look very white. Light-enhancing and whitening agent is a chemical whitening dye that absorbs ultraviolet rays and can show fluorescence. After entering the human body, it is not as easy to decompose like ordinary chemical components. Instead, it quickly combines with proteins in the human body and is difficult to excrete it out of the body. This undoubtedly increases the burden on the liver, and fluorescent agents are very prone to irritation on the human skin. Some people think that clothes are not only bright after whitening, but also clean and sterile, which is completely a misunderstanding.
The most harmful car paint when washing the detergent car was seen washing the staff very seriously, and the washing bubbles were flying all over the sky, so many car owners thought that as long as the dirty car was delivered to the car wash, everything was "OK” after washing, it looked clean from the outside. If you want to know what the car wash shop uses to wash your car, you can pinch it with your fingers and smell the bubbles with your nose, and you will find that it is laundry detergent! Laundry detergent is an alkaline detergent that has great damage to car paint. If washing the car with laundry detergent for a long time, the surface of the car will gradually lose its luster. And when the owner finds that his car has problems with his car, it will be too late to regret it.
Use laundry detergent as dishwashing agent
Some households use laundry detergent to wash tableware, which is very bad. The main ingredient in laundry detergent is sodium alkylbenzenesulfonate, which is moderately toxic. If its particles adhere to the tableware and enter the human body through the gastrointestinal tract, it can inhibit the activity of pepsin and pancreatic enzymes, thereby affecting the digestive function of gastrointestinal cells, and also damage liver cells and lead to liver dysfunction. Over time, it will cause diarrhea, indigestion, liver and kidney abnormalities, spleen shrinkage and even cancer, and lead to blood disorders. Therefore, do not use laundry detergent as dishwashing agent.
The good-tasting laundry detergent may not be good
Most people who buy detergents consider whether they are clean and clean, the second consideration is whether the fragrance is good. However, the vast majority of fragrances are artificially synthesized and 95% of its chemical ingredients come from petroleum, such as benzene and aldehydes, which can cause carcinogenic and can also cause reproductive disorders, but are more common to allergic dermatitis.
Dark detergent does not hurt your hands
Some manufacturers have launched “ "Dark detergent does not hurt your hands" and “ "Dark detergent does not hurt your hands" and so on. Synthetic detergents are essentially chemical products, and they will cause more or less damage to the skin while removing stains. After the skin is exposed to alkaline laundry detergent for a long time, the weak acid environment on the surface of the skin will be damaged, which will lead to skin problems such as rash, erythema, desquamation, eczema, etc. If it is absorbed too much into the body through the skin, it may also damage the body's hematopoietic function, lymphatic system and liver function, and some may even be at risk of cancer. Therefore, when washing clothes by hand, it is best to use soap.
The effect of multi-functional laundry detergent may not be good
Many laundry detergent advertisements promote the addition of certain new ingredients, which have more and stronger washing functions.. These ingredients mainly include surfactants, builders, stabilizers and enzymes, so as to achieve the purposes of easy soluble, cleansing, softening, foaming, and preventing static electricity in clothing. But the more substances added to laundry detergent are not a good thing for our health.
Commonly used builders are harmful to the human liver; while surfactants were found to destroy the stratum corneum of the skin and cause rough skin. They are now regarded as a major pollution hazard to pollute the environment: In addition to absorbing water, the alkaline substances contained in strong laundry detergent can also destroy the human cell membrane and denature tissue proteins: the organic chlorine and fluorescent agents contained in whitening laundry detergent are toxic substances, which are easy to accumulate in the human body and cause damage to health.
Avoid universalizing washing powder
In life, many people regard washing powder as a "universal detergent". In addition to washing clothes, they also use it to scrub furniture and floors, believing that it has the effect of decontamination, disinfection and sterilization. Little do they know that doing so may cause laundry detergent to enter the human body. Experts remind that even if the amount of laundry detergent entering the body is very small, it will cause toxicity. Do you still dare to use one powder for more?
Do not mix laundry detergent and disinfectant.
Many housewives are used to adding some disinfectant to sterilize their clothes. Some people simply put the laundry detergent and disinfectant into the washing machine at the same time. In fact, this will not only not have a sterilization effect, but will also be harmful to human health.
Disinfectant is a chlorine-containing phenolic disinfectant, and excessive or incorrect use is also dangerous. Laundry detergent mostly contains surfactants. If the laundry detergent and disinfectant are mixed, chemical reactions are easily caused to weaken their respective effects. In addition, if chlorine-containing disinfectant is mixed with acid-containing laundry detergent, chlorine will be produced. When the concentration of chlorine is too high, it will stimulate the eyes, nose, throat and other organs. In severe cases, it will damage the heart and lung tissues of the person and even endanger life.
Therefore, the normal washing method should be: add 3 to 5 drops of disinfectant to a bucket of water in the washing machine, or add water to make a 1% to 5% disinfectant solution, put clothes, sheets, etc. in soak for 30 to 60 minutes, and then wash them normally with washing powder.
