1, the aroma components are suspicious.
Few people will consider the safety of perfume and other fragrances, and few people will know that at least 5000 chemical components are needed to make fragrances. Every perfume has more than 600 chemical components. Of these more than 5,000 chemical components, less than 20% have been tested for toxicity. Therefore, they are all toxic and classified as dangerous goods by many countries. Whether other untested ingredients are toxic or not is unknown. More than 100 components in perfume can be detected in the living room (the most commonly used chemical component of perfume is 150), most of which are known to be toxic.
2. Aromatics may be harmful to health.
Studies have found that the chemical composition of fragrances is harmful to health, especially to the skin, lungs and brain. Many people complain about the side effects such as urticaria and dermatitis after using perfume. Aromatic hydrocarbons have a great influence on patients with chronic lung disease, especially asthma. According to statistics, in the United States alone, as many as 75% (about 9 million patients) of asthma cases are induced by perfume.
Aroma is related to memory, that is to say, aroma has an effect on brain tissue. This effect is called neurotoxicity. For example, the rich aroma components in perfumes and other essences can induce symptoms such as depression and depression, and even life-threatening respiratory diseases.
Perfume notes:
(1) Perfume should be stored in a cool place to avoid hot air and light. If the perfume is placed at high temperature, the color and fragrance of the perfume will change. If you want to keep perfume for a long time, you can wrap it in wrapping paper and put it in the refrigerator.
(2) Try to avoid rubbing and gently shaking the perfume bottle.
(3) Don't touch the bottle mouth directly with dirty fingers, which may destroy the original flavor of perfume.
(4) After the perfume is used up, be sure to tighten the bottle cap to avoid the fragrance of the perfume from evaporating.
(5) It can be stored upside down to prevent air from entering the bottle through the bottle mouth. Perfume can generally be kept for about a year, just at room temperature. If the fragrance is found to be weak or sour, it should be discarded.
