Frequent flyers know that the regulations for carrying liquid items on a plane are quite strict and complex. Typically, female passengers are allowed to carry only a small amount of liquid cosmetics. The total volume must not exceed 1000 ml, and each container must be no larger than 100 ml.
However, even if these rules are strictly followed, there are other important regulations regarding liquid cosmetics that might be overlooked. Flammable and explosive liquid cosmetics cannot be carried on board or checked in, meaning they won't pass security checks.
So, can you bring nail polish, a common beauty product, on a plane? This is a concern for many female passengers. Let's look at the regulations for carrying nail polish on a plane.
Nail Polish Ingredients
Nail polish is a cosmetic used for manicures, typically composed of cleaners, solvents, and pigments. It contains various chemicals such as ethyl acetate, acetone, and nitrocellulose, which give nail polish its fast-drying, durable, and vibrant characteristics.
Normally, we don't pay much attention to these ingredients, focusing only on the cosmetic effect. However, when flying, many of these components are classified as flammable substances. For instance, main ingredients like ethyl acetate, acetone, and nitrocellulose are highly flammable.
Regulations for Flammable Items
The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). See the FAA regulations for more information.
Safety Concerns of Nail Polish on a Plane
The main reason nail polish is prohibited on planes is due to safety concerns. During a flight, changes in cabin pressure and temperature can cause the flammable components in nail polish to vaporize, increasing the risk of fire or explosion. Additionally, if a nail polish bottle leaks during the flight, its chemical components could pose a health risk to other passengers.
Alternative Solutions
Given that nail polish cannot be carried on board or checked in, passengers should check their cosmetics to ensure they do not include such items. If they do, these items should be left at home to avoid confiscation at security.
For frequent flying nail art enthusiasts, consider using safer solid nail products, such as nail stickers. These are convenient to carry and pose no flammable risk. It's important to note that some solid nail polish products may still contain flammable solid substances and thus are also not allowed on board or in checked luggage.
After reading this article, you should now understand why nail polish cannot be taken on a plane. Due to its flammable and explosive chemical components and potential safety risks, nail polish cannot be carried on board or checked in as luggage. Be sure to check your cosmetics for nail polish before traveling.
