Do you know the poison of second-hand cosmetics?

Some time ago, I watched the movie "Dark Waters" about Teflon, and then I realized that the two chemicals used in the production of Teflon, PFOA and PFOS, are both environmental hormones. Plays a role similar to estrogen and affects the body's endocrine levels. And because they will not degrade, even if the production process is changed now, their harm to the environment and human body has already occurred and will continue for a long time.

　　 Coincidentally, the food wrappers of McDonald's and Burger King have recently detected fluoride PFAS in the United States, which is also an environmental hormone that is difficult to degrade. Just to make the packaging oil-proof and waterproof, but also to bear the risk of environmental pollution, I think it is not worth it.

From this I thought, in fact, certain preservatives, antiperspirants, aerosols, deodorants, breast enhancement ingredients, sunscreen ingredients, plasticizers, non-ionic surfactants, etc. in cosmetics are also environmental hormones, even Aloe vera (2021 hermes bags) and kudzu root (containing mirolol/deoxymirolol), which are generally considered safe plant ingredients, as well as the artificial musk in perfume, have also been reported to have estrogenic activity.

Environmental hormones in cosmetics can directly enter the human body through skin contact, and the more important way for them to accumulate in the human body is the "second-hand" pathways such as food, water and even air, and the intake of second-hand pathways is larger than that of primary pathways. many.

Taking into account the daily use of daily chemical products, the potential impact on us should not be underestimated. For this reason, we need to know whether there are pollution problems that the public overlooked under the beautiful appearance of Meiye?

　　Environmental hormones can interfere with the body’s normal hormone levels

Environmental hormones (Environmental Endocrine, EDCs), also known as "hormones" and "endocrine disrupting substances", refer to substances in the environment that are similar to human hormones. After entering the human body, they will interfere with normal hormone levels. The system may have an impact.

The most common effect of environmental hormones is the estrogen-like effect, which not only damages the quality and quantity of male sperm, and reduces fertility; it can also cause infertility and breast tumors in women; and even cause precocious puberty and abnormal development of sexual organs in children. .

　　 More than 70 environmental hormones have been discovered so far, including dioxins from waste incineration, o-xylene esters in plasticizers, bisphenol A in plastic baby bottles, and shopping receipts. In a joint report released by the World Health Organization (WHO) and the United Nations Environment Programme (UNEP) in 2013, environmental hormones were defined as "a global threat to human health and the environment."

　　 The fragrant fragrance is not necessarily a good thing

The environmental hormones contained in cosmetics are mainly synthetic fragrance compounds, such as phthalic acid and benzoate (also common preservatives), the precursors of fragrances, and fragrance substances themselves such as artificial musk, which can interfere with estrogen. System-sometimes the fragrant ones are not necessarily good things.

　　 Take the most common fragrance ingredient-artificial musk-for example. The artificial musk was originally produced to reduce the damage to musk and played an active role in wildlife protection. But with the widespread use of this cheap spice, the environmental problems it causes have gradually become prominent.

　　 Artificial musk is mainly used in perfumes, cosmetics and bath products, such as lipsticks, hand creams, shower gels and so on. It will enter the sewage collection system with people's daily life. Because there is no treatment measure for synthetic musk, it will be directly discharged into rivers and oceans.

Artificial musk can be dissolved in water and is lipophilic. Although it has a certain degree of degradability, it is now generally enriched in the environment and organisms under continuous discharge-in the fat of lipid-rich marine mammals (such as dolphins, sperm whales, seals, sea lions, etc.) It can be detected in the liver and the liver; it is also found in the livers of birds such as merganser, pochard and wild duck; it is also found in the tissues of fish, shrimp, and shellfish.

　　 Humans consume more synthetic musk than animals, because it not only penetrates directly into the skin through the use of cosmetics and perfume, but also produces biomagnification and accumulation through the food chain.

Of course, the reason why artificial musk can be widely used in daily chemical products is because it has no obvious harm to the human body. It only shows certain estrogenic activity in cell-level research. In addition, it is relatively harmful to mammals. small.

　　 However, the harm of artificial musk to aquatic animals cannot be ignored. For example, it can reduce the weight, body length, liver index and gonadal index of female zebrafish, and as the concentration increases, the zebrafish's ability to lay eggs gradually decreases. Muscone also increases the early mortality of zebrafish embryos and reduces the average survival time.

　　 At present, scientists have begun to study the environmental pollution, ecological behavior and toxicological effects of synthetic musk, but it is still in its infancy.

There are still controversies regarding the risk of artificial musk polluting the environment, and there is no standard setting for artificial musk testing, but many countries have initiated certain management measures:

Japan has detected synthetic musk residues in breast milk and adipose tissue. It is believed that synthetic musk has side effects such as disrupting endocrine and affecting the normal functioning of biological hormones. In 1993, the use of some synthetic musk was banned;

The European Union completely banned sunflower musk in 1995, banned the addition of umbel musk and Tibetan musk in cosmetics in 1998, and listed musk xylene and musk ketone in "limited use" in 2008 and was completely banned in 2013;

China banned the use of sunflower musk in 1999.

　　 The dark side of sunscreen to animals

　　 Similar to artificial musk, environmental hormones that can accumulate in animals and various ingredients in sunscreen.

Cinnamate, trimethylcyclohexyl salicylate, 3-benzylidene camphor (3-BC), p-aminobenzoic acid (PABA 2021 hermes bags), 4-methylbenzylidene camphor (4-MBC), oxybenzone, etc. Such substances have shown obvious hormonal interference effects in animals, which can cause growth inhibition, reproduction inhibition, teratogenesis and death.

　　 In addition, benzophenone-3, an ultraviolet absorber commonly used in sunscreens, is also an environmental estrogen.

Even inorganic sunscreen ingredients (the main function of inorganic sunscreen ingredients is to reflect and scatter ultraviolet radiation, while organic sunscreen ingredients act as sunscreen by absorbing ultraviolet rays), but they are also harmful to marine life. Titanium dioxide particles entering the seawater can promote the production of hydrogen peroxide under light, and hydrogen peroxide has obvious toxicity to marine life (for humans, titanium dioxide powder may cause cancer if inhaled in the respiratory tract). At present, zinc oxide sunscreen is relatively safe and environmentally friendly. However, some studies have found that after sea urchin embryos are exposed to zinc oxide particles, they never develop into sea urchin larvae, or seem to develop normally, but will eventually be unable to develop. Eat and die.

　　 A study published in the Journal of Environmental Pollution and Toxicology in 2015 showed that scientists estimate that as many as 14,000 tons of sunscreen enter the ocean every year. Sunscreen ingredients can now be found in dolphins, fish, and bird eggs.

　　 So, although sun protection is really important, you don’t need to over-apply sunscreen. Instead, use umbrellas and caps as appropriate, which is better for yourself and nature.

Although we talked about the harm caused by many environmental hormones contained in cosmetics, overall, cosmetics are still safe and usable. We don't have to waste food because of choking. After all, environmental hormones that are clearly harmful to the human body have been banned from being added to cosmetics. Moreover, the main intake of environmental hormones by the human body is through “second-hand” channels such as food and water. To fundamentally control emissions in the environment, it is mainly dependent on government monitoring and management.

　　 However, on the other hand, we are not completely passive. Even if we cannot control the second-hand intake, we can at least reduce the first-hand exposure-by using less cosmetics, we can actively reduce its accumulation in the body.

　　 The movie "Black Water" reflects a helpless reality: the speed of supervision can never keep up with the speed of innovation in chemical products. Therefore, even if cosmetics have a regulatory blacklist, short-term toxicological and pathological tests may not be able to avoid all risks. At present, many substances that have shown hormone interference effects (reproductive abnormalities, animal feminization, carcinogenic and teratogenic) in animal studies are still used in the daily chemical industry. Therefore, it is best not to use cosmetics for a long time and in large quantities, especially perfume and sunscreen, to control the release of environmental hormones from the source.

Cosmetics will also be deposited in the dust in the house, so families with children especially need to clean the indoor environment in time and reduce the use of cosmetics, because children like to crawl and lick food on the floor, and are more sensitive to environmental hormones, so they are exposed to childhood May affect life.

Cosmetics(replica hermes) are chronically exposed for a long time. On average, most women come into contact with at least one hundred cosmetic ingredients every day. It is not an exaggeration to be careful. Moreover, even if these ingredients are harmless to humans, they are not necessarily harmless to nature and other living things. This pandemic reminds us again that we must pay attention to the way and degree of claiming the earth. The beauty lies in ourselves and the beauty lies in nature.
