Introduction to perfume testing
Perfume is a liquid that mixes essential oils, fixatives, and alcohol and ethyl acetate to give objects (usually the human body) a long-lasting and pleasing scent. Essential oils are obtained from flowers and plants, and are extracted by distillation or liposuction. Organic compounds with fragrance can also be used. Fixatives are used to combine a variety of different flavors, including balsam, ambergris, and secretions from the air glands of civet cats and musk deer. The concentration of alcohol or ethyl acetate depends on whether it is perfume, eau de toilette or cologne.
The dangers of poor perfume
Most of the quality perfumes are extracted from natural plants. The fragrance is pure and harmless to the body. Expensive big-name perfumes will clearly indicate that they are derived from natural floral ingredients, while ordinary perfumes are natural fragrances and other chemically synthesized fragrances. The strong and pungent aroma is mostly due to the aromatic compounds. Although they try to mimic the fragrance of natural flowers, the concentration of artificial fragrance molecules far exceeds the concentration secreted by natural flowers.
Perfumes are now added with a phthalate (DEHP) ingredient for long-lasting fragrance. Phthalates are actually a family of chemical substances containing more than 10 specific compounds, and not all phthalates are explicitly banned. But DBP, BBP and DEHP are carcinogenic and toxic to the reproductive system.
Studies have long confirmed that frequent exposure to aromatic volatile substances can cause different degrees of stimulation to human organs, especially the respiratory tract, skin and central nervous system, and may cause skin allergies, asthma, dizziness, chest tightness, and dyspnea. Many people complain about side effects such as urticaria and dermatitis after using fragrance. Aromatics have a significant effect on chronic lung disease, especially in patients with asthma. According to statistics, in the United States alone, up to 75% (about 9 million patients) of asthma cases are caused by perfume.
The pain caused by perfumes doesn't stop there. Some fanatics of perfumes apply perfume to all exposed skin in order to let themselves exude a charming scent. As a result, patches of redness are formed. This is because certain ingredients in the perfume, such as trace amounts of copper, alcohol and lemon, may produce chemical reactions under the sun, decompose harmful substances, sensitive skin will be irritated, redness, tingling, etc. may even cause contact. dermatitis. Therefore, it is best to apply the perfume out of the sun.
People with allergic asthma and dermatitis are better off. Perfume is likely to become an allergen. Not for use by pregnant or nursing mothers. In particular, children are more susceptible to fragrances than adults. Unfortunately, almost all baby products on the market have added fragrance. If parents often spray perfume, it will poison the air that the children around them breathe, causing children's inattention, learning difficulties, excessive activities, and even serious hazards such as convulsions and stunting.
