The research report published by the National Cancer Institute of Australia in 2009 shows that the alcohol content of mouthwash is 25% or higher, which is related to the canceration of the mouth, tongue and throat.
2. preservatives in bread bread is soft and delicious, which many people think is a healthy breakfast. But did you know that besides wheat, milk and sugar, bread also has a preservative called calcium propionate (e282). This preservative was quietly introduced into bread more than 20 years ago. It is a colorless and tasteless white powder, which can not be distinguished by its appearance, smell and taste. Its harm to the human body is gradually accumulated. Studies have proved that it is related to upper intestinal dysregulation and migraine, and also leads to children’s learning difficulties and continuous fatigue.
3. Diethanolamine (DEA) in wash and care products although bath gel and moisturizer can clean your skin, they will hurt your health unknowingly. It contains a substance called diethanolamine, which is used as a solvent, emulsifier, detergent and moisturizer. In the book saving face: spices shaping wrinkle free skin published in 2002, the Canadian writer Sabina Devita introduced that diethanolamine is used as a softener in skin care milk, but it will react chemically with nitrate in the product to form a potential carcinogen – nitrosamine. In addition, diethanolamine may also irritate the skin and mucosa.
4. Fluoride in toothpaste toothpaste on the market contains fluoride more or less, which can prevent tooth decay. However, fluoride is also a potential “poison”. Even if only a small amount is ingested, it will cause adverse effects on health and even poisoning, and the toxicity can accumulate gradually. A study by the National Cancer Institute of the United States found that fluorination reaction was related to cancer deaths in the United States every year. In this regard, Wang Peng, doctor of the Prevention Department of Beijing Stomatological Hospital Affiliated to Capital Medical University, reminded that fluoride toothpaste must be used correctly. Adults should not exceed 3.4 mg per day, and children aged 7 to 15 should not exceed 1.9 mg to 2.1 mg. Children under 3 years old are prone to swallow toothpaste by mistake when brushing their teeth. It is recommended that fluoride toothpaste should not be used for the time being.
5. Formaldehyde in nail polish in recent years, there are more and more nail salons on the street. The passion for beauty makes many people ignore the pungent smell of nail polish. In fact, the culprit of this smell is formaldehyde, which we often talk about and avoid. If the contact time is long, it will cause inflammation of eyes, nose and throat, cough, asthma attack, shortness of breath, nausea, vomiting, rash, epistaxis, headache and dizziness. Since 1987, the international agency for research on cancer (IARC) has listed formaldehyde as a class 2A carcinogen. The US Environmental Protection Agency (EPA) also stated that long-term and high-frequency use of formaldehyde containing substances would have potential cancer risks.
6. P-phenylenediamine in hair dye fashionable men and women constantly change the color of their hair, and middle-aged and old people dye their gray hair black to show their youth. Little did they know that most hair dyes in the market use a chemical substance – p-phenylenediamine, which can help color and make their hair bright, but it can also lead to skin hypersensitivity and even cancer. Li Xinquan, director of the Hematology Department of the Beijing Armed Police General Hospital, reminds that if you need to heat your hair when dyeing, it will be more harmful to your health, because after heating, p-phenylenediamine will enter the capillaries through the scalp and may cause leukemia and other blood diseases along with the blood circulation. In addition, p-phenylenediamine is also prone to induce skin cancer and bladder cancer. When dyeing hair, it is best to smear some moisturizing lotion on the skin next to the hairline, so that it is easy to wash off after being stained with the lotion; If the hair is partially gray, it is not necessary to dye the whole head black. You can only dye the white part to reduce the irritation and damage to the scalp.
7. Propylene glycol in wet wipes both ordinary wet paper towels and baby wipes contain a common raw material propylene glycol, which is a petrochemical solvent that can easily penetrate into the skin, and its harm to the body can not be ignored. It accumulates in the heart, liver and kidney, causing their distortion and damage, and weakening the immune system. In addition, it will damage the cell membrane, causing rash, dry skin, contact dermatitis and skin surface damage.
8. Foaming agent in baby care products baby care products should be the most reassuring, but the fact is that they also contain substances harmful to human body. Sodium dodecyl sulfate is one of the most commonly used blowing agents in cosmetics and personal care products. After oxidation, sodium dodecyl ether sulfate is formed. Because it is less irritating to eyes, it is often used in mild care products and baby care products. However, during its oxidation process, an extremely harmful compound – 1,4-dioxane, which is a hormone interferon, will be produced. After the Vietnam War, a large number of Vietnamese military personnel have been suffering from cancer. In addition, it is also a kind of estrogen, which is believed to increase the chance of suffering from breast cancer and endometrial cancer, and is significantly related to the low number of sperm and morbid conditions.
9. Talc powder in makeup when women buy cosmetics, they must remember that most of the tiniest powdered cosmetics, such as eye shadow, rouge, foundation make-up and so on, contain talc. This is a very fine lubricant with chemical properties similar to asbestos. It is a known carcinogen and is related to the increase in the number of patients with ovarian cancer and respiratory diseases. A report published in the American Journal of epidemiology shows that women who use talc have a 60% increased risk of ovarian cancer. In addition, talc powder must not be used in baby skin care products such as talcum powder. In addition to causing cancer, it may also cause acute respiratory pressure after inhalation.
10. Toluene in perfume if you have asthma, you must remember to stay away from nail polish, hair gel, hair wax, perfume and other cosmetics, because almost all of them contain toluene, which is used as a solvent. Studies have proved that inhalation of high concentration of toluene in a short time may cause obvious irritation of eyes and upper respiratory tract, which is manifested by congestion of conjunctiva and pharynx, dizziness, headache, nausea, vomiting, chest tightness, weakness of limbs, staggering gait, blurred consciousness, etc. If exposed for a long time, it may cause chronic poisoning, neurasthenia syndrome, hepatomegaly, or abnormal menstruation, dry skin, chapped skin, dermatitis, etc. If you are a fan of perfume and it is hard to give up, you can consider using plant essential oil instead.
