Frequent use of this kind of laundry detergent may cause illness

1. I like scented laundry detergent

When most people buy detergents, besides considering whether it cleans well, the second thing they consider is whether it smells good. However, the vast majority of spray fragrances are artificially synthesized, and 95% of their chemical raw materials come from kerosene, such as benzene and aldehydes, which may cause cancer and reproductive disorders, but more commonly cause allergic dermatitis.

2. Wash clothes by hand with detergent

When the skin is in direct contact with alkaline laundry detergent for a long time, the weak acid environment of the skin epidermis will be damaged, and its effect of inhibiting bacterial growth will disappear, which can easily lead to skin itching, or even symptoms such as allergic dermatitis, or leave pigmentation deposits on the skin. So when hand washing clothes, it is best to use soap.

3. Use laundry detergent as a universal cleaner

In life, many people regard laundry detergent as a "universal cleaner". In addition to washing clothes, they also use it to scrub furniture and floors, thinking that it has the functions of removing dirt, disinfecting and sterilizing. Little do people know that doing so may cause the detergent to enter the human body. Experts suggest that even a very small amount of laundry detergent that enters the body can cause poisoning. Do you still dare to use one powder for multiple purposes?

4. Washing powder can be used for a long time

Ordinary laundry detergent can generally last for two years under the correct storage environment, but laundry detergent with special ingredients added may not last for more than two years. When storing laundry detergent, it is best to put it in a plastic bottle or jar with a lid. On the one hand, this can prevent the detergent from absorbing moisture and clumping; on the other hand, it can also prevent the fragrance from evaporating and causing people to inhale more synthetic flavors.

5. Multifunctional laundry detergent is better

Many laundry detergent advertisements claim that they have added certain new formulas to provide better and stronger washing effects. These formulas mainly include surfactants, builders and enzymes to achieve the purposes of solubility, cleaning, softening, foaming and eliminating static electricity in clothes. But there are too many substances added to laundry detergent, which is not good for our health.

Commonly used detergents are harmful to the human liver. Surfactants have long been found to damage the skin's stratum corneum and cause rough skin, and are now regarded as a major public hazard to the environment. In addition to affecting water quality, the alkaline substances contained in strong laundry detergents can also damage human cell membranes and denature structural proteins. The organochlorine and fluorescent agents contained in whitening laundry detergents are toxic substances that can easily accumulate in the human body and cause harm to health.

6. Washing powder and disinfectant are the best partners

Many people are accustomed to adding some disinfectant when washing clothes to remove bacteria. Some people simply put laundry detergent and disinfectant into the washing machine at the same time. In fact, this not only fails to achieve a sterilization effect, but is also harmful to human health.

Disinfectant is a chlorine-containing phenol disinfectant, and excessive or incorrect use can also cause harm. Washing powder contains a lot of surfactants. If washing powder and disinfectant are mixed together, a chemical reaction will easily occur, weakening the functions of each. In addition, if chlorine-containing disinfectant is mixed with acid-containing laundry detergent, chlorine gas will be produced. 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 the heart and lung function and even endanger life.

Therefore, the normal washing method should be: add 3 to 5 drops of disinfectant in a bucket of water in the washing machine, or add water to make a 1% to 5% disinfectant solution, soak clothes, sheets, etc. for 30 to 60 minutes, and then use detergent to wash normally.

7. Washing clothes with hot water makes them cleaner

The higher the water temperature for washing clothes, the better. Since we often use various types of enzyme-containing laundry detergents, the enzyme preparations in them mainly include alkaline proteases and alkaline lipases. Alkaline proteases are used to break down protein stains, such as sweat stains, blood stains, etc.; alkaline lipases mainly act 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 affect the activity of the enzyme.

Secondly, protein has a denaturing effect. Its most notable characteristic is that the protein coagulates and its fluidity is significantly reduced. An example is the coagulation of eggs after cooking. One of the causes of denaturation is high temperature. The same is true for protein stains on clothing. Therefore, if the water temperature is too high when washing clothes, they will denature and agglomerate on the fabric fibers, making them more difficult to wash.
