We’ve all heard the misleading claims that nail polish is harmful unless it’s “3-Free”. The facts are that this was deception from the very beginning. All nail polish can be used safely, and that’s been true for more than eighty years. Nail polish formulas haven’t changed much since the 1930s. How did they so suddenly become dangerous? I don’t know of any cases when nail polish has harmed anyone, other than it catching fire. Fresh nail polish is flammable – so don’t do as my friend did and light up a cigarette immediately after polishing your nails. All nail polishes are safe. Those that market their polish as “safer” are splitting hairs. It’s like saying that using an SPF 70 lotion isn’t as safe as SPF 80. The fact is both are safe. Don’t be concerned about nail polish causing any harm to your health, when used as directed.
Tất cả những thông tin sai lệch về sơn móng tay này bắt đầu như thế nào?
Nó bắt đầu như một chiến dịch tiếp thị thông minh và lừa đảo cao độ của một nhóm hoạt động dựa trên nỗi sợ hãi. Nhóm này đã tạo ra mối quan tâm an toàn sai lầm và sau đó kiếm tiền từ các khoản quyên góp, tuyên bố rằng họ đang cứu thế giới khỏi loại sơn móng tay nguy hiểm! Họ đã đưa ra những tuyên bố phóng đại về các thành phần để gây sợ hãi không cần thiết cho công chúng.
Toluen
Ví dụ, họ tuyên bố rằng toluene nguy hiểm trong sơn móng tay, nhưng thông tin đó trái ngược với sự thật. Hội đồng chuyên gia đánh giá mỹ phẩm (CIR) uy tín đã đánh giá toluene. Sau khi xem xét công bằng tất cả các thông tin khoa học, hội đồng gồm các bác sĩ và nhà khoa học đẳng cấp thế giới này đã xác định rằng toluene được coi là an toàn ở hàm lượng lên đến 50% trong sơn móng tay. Liên minh châu Âu đã thực hiện cùng một thử nghiệm và kết luận rằng toluene an toàn trong sơn móng tay lên đến 25%. Đó là nồng độ thường được sử dụng. Do đó, các chuyên gia khoa học độc lập ở cả Hoa Kỳ và EU đều cho rằng toluene an toàn khi sử dụng trong sơn móng tay.
Vậy tại sao toluene không còn được sử dụng cho mục đích này nữa?
Manufacturers voluntarily eliminated toluene because it is a volatile organic compound (VOC), and it was found to contribute slightly to ozone depletion. Nail manufacturers wanting to do their part for the environment agreed to replace toluene with other solvents. Even so, these fear-based advocacy groups again deceived the public! They pretended that manufacturers change because of toluene’s toxicity, which is an outright lie. These same activist groups lie to the news media as well, and tell them that even nail polish formulas with <0.1% toluene are still toxic – even though this is contrary to all of the scientific facts. These groups pretend there is no safe amount of anything they say is dangerous. This just shows they don’t understand the science or the facts. Instead, they want the world to be black and white, when this clearly isn’t so.
Dibutyl phthalate (DBP)
Dibutyl phthalate (DBP) is another example. This ingredient hasn’t been used very much at all in nail polish formulas for at least ten years, but that didn’t stop these groups from stretching the truth. It is no longer used, even though it has been found to be safe for nail polish applications. Better replacements are now used to increase the wearability of nail polish, which was how DBP functioned in polish. There has NEVER been any credible evidence to show that DPB was harmful in nail polishes. Other phthalates with similar-sounding names were determined to be unsuitable for cosmetics, but these were never used in nail polish.
The fear-mongering activists paint everything with a broad brush so, without evidence, they assumed that DBP must also be dangerous. In other words, rather than explain that some phthalates are safe, they decided to scare consumers by telling them that all phthalates are dangerous, again, because they don’t understand the facts. They hide their lack of knowledge and reduce everything to black and white. They don’t like the scientific facts; they’d rather base their unfair attacks on pure speculation.
Formaldehyde
Formaldehyde at room temperature is a gas, but in cosmetic manufacturing it is usually stored and used in a water-based liquid form, such as formalin hoặc methylene glycol. Historically, these liquid forms were used in some nail hardeners. In nail polishes, formaldehyde has been present mainly as tosylamide/formaldehyde resin (TSFR), a polymer that improves shine, durability, and adhesion. While resin forms remain the standard in polishes today, the fact that free liquid formaldehyde has been used in certain nail treatments in the past is important to note.
Years ago, nail polish manufacturers were required to call this resin by a name that included the word “formaldehyde,” even though it is chemically very different from the gas or liquid form of formaldehyde itself.
The name of the resin was toluene sulfonamide formaldehyde resin (TSFR). This isn’t toluene or formaldehyde. These substances were used to make a completely different ingredient and, because they were made using these ingredients, it was assumed that they were in the polish. However, when this resin is used, the nail polish might contain 0.0005%. So you can’t technically say they are “formaldehyde-free”, but for all practical purposes, they are indeed free of formaldehyde. Because of the misinformation spread by these fear-mongers, nail manufacturers worked behind the scene to have this misleading name corrected. Some may still use the old name for this ingredient, but this is slowly changing as manufacturers update their labels.
