Life cleaning products, cosmetics have entered thousands of households, but also become a lot of people’s necessities, these things bring convenience to our lives, but their chemical composition do you really understand? What do you need to pay attention to when buying and using them? The following is a brief introduction: 1, cosmetics Many cosmetics (including lipstick) contain a very small amount of formaldehyde. It is generally believed that because the amount is very small, there is no need to control. However, the results of some studies have shown that the incidence of cancer among cosmetologists has increased compared to other populations. Although the vast majority of cosmetics sold on the market are considered safe, there are still some that contain formaldehyde and should be avoided. For example: nail polish, permanent hair dye, etc. Especially permanent hair dye, which is a cosmetic product used by millions of women, contains a suspected carcinogen, which may cause cancer or blood disease. 2, cleaning products Benzene is a chemical solvent often contained in household cleaners, stain removers, solvents and glues. People and animals inhale or skin contact with large amounts of benzene into the body, will cause acute and chronic benzene poisoning. In addition, it can inhibit the body’s hematopoietic function, which can lead to the reduction of white blood cells, red blood cells and platelets and cause a variety of diseases. A large percentage of leukemia patients have a history of exposure to benzene and its organic products. Benzene is used to synthesize a variety of compounds and is also used in a wide range of products, from shoe adhesives to pesticides, inks and paints. Some industries that use large amounts of this chemical are at greater risk from long-term exposure to benzene. In addition, we should avoid using cleaners that contain the carcinogens carbon tetrachloride and perchloroethylene. If you must use these products, make sure the room is well ventilated. PCBs are commonly used in the manufacture of hydraulic fluids, transformer coolants, lubricants, and plasticizers. Some old plastic products, paints and adhesives made 10 years ago; sealants, inks and other items that are stored in homes today may also contain PCBs. The common types of blood diseases caused by formaldehyde, benzene and other chemicals are: 1, leukopenia and granulocyte deficiency 2, aplastic anemia 3, myelodysplastic syndrome 4, leukemia, etc. Therefore, we should buy qualified products to avoid excessive carcinogens inside. We can not let these household products facilitate our life but damage our health, which is not worth the loss for us.
