What is Acrylic Nail Powder? (2024)

Acrylic nail powder is a substance used to create acrylic nails. It is not used alone, but rather is combined with a liquid chemical that makes it harden. Commonly applied both in salons and at home, it is easy and relatively inexpensive to buy. Generally considered safe, it can provide some temporary protection to the nails and improve their appearance, but the way that acrylic nails must be removed means that using it has some risks.

Ingredients

The main ingredient used in acrylic nail powder is polyethylmethylmethacrylate, commonly called PMMA, which is a combination of two different monomers, ethyl methacrylate (EMA) and methyl methacrylate (MMA). It also usually contains substances such as benozophenone-1, which help keep the powder from discoloring when exposed to ultraviolet light. Benzoyl peroxide is included, as well. To meet the fashion demands of consumers, manufacturers also produce versions that have pigments added, usually at a concentration of around 2%, which lets people choose from a wide range of colors. Some even have additional ingredients such as glitter.

How It Works

When used for nails, people mix acrylic powder with a monomer liquid, which usually is EMA plus some additional ingredients that keep the molecules from joining together too soon, prevent yellowing, provide color or affect flow and spreading. During this process, the benzoyl peroxide in the powder acts like a catalyst, causing the liquid monomer to form very strong, net-like bonds called crosslinks between each powder particle. The result is a hardened resin.

Application

Normally, salon technicians apply mixed acrylic nail powder and the liquid monomer with a clean, soft brush designed for use on nails. They usually work from the bottom of the nail up to the tip, moving from the center outward. The fact that the chemical reaction that causes it to harden begins as soon as the two substances come in contact with each other means that technicians cannot premix them. Over time, individuals who apply acrylic nails learn to eyeball how much of each they’ll need so that they aren’t wasteful.

Applying the powder at home is a viable option for people who do not want to spend the time or money to go to a salon. Many individuals find that it is convenient to do this because when their nails grow out, they can easily fill in the gap that forms at the base of the nail with more acrylic. They also can take care of their nails whenever they have free time, rather than needing to worry about getting to an appointment.

Removal

To remove the resin that forms from mixing the acrylic nail powder and the liquid monomer, people must soak or wrap their nails in solvents. The most common one used is acetone, which many people do not like because of the potentially hazardous side effects, such as irritation of the respiratory tract, dizziness and nausea. The removal process usually takes at least 20 minutes, and many people file down the nails first to speed things up. To prevent the drying out of the skin that acetone can cause, individuals often apply petroleum jelly around the nails before starting and again when they’re done.

Availability

This product is standard in modern nail salons. People also can buy it in beauty or cosmetic supply stores and departments. Some individuals prefer to buy it from online retailers, which is often cheaper despite having to pay shipping costs.

Safety

There is widespread confusion regarding the safety of acrylic nail powder, largely because it contains MMA, which has been banned by agencies such as the Food and Drug Administration (FDA). These bans, however, deal with the liquid monomer form of the chemical, not the solid, polymer form that appears in the powders. The latter version is said to be safe because the molecule is so much larger, making it unable to penetrate the skin. It is easy to tell when a manufacturer has used the monomer type of MMA because it has a very strong smell, doesn’t soak off easily and is hard to file.

Although acrylic nail powder by itself is not thought to pose a health risk, it requires solvents to remove. These chemicals often produce fumes that can be toxic, and they can cause irritation when they come in contact with the skin. They also have been shown to reduce the thickness of the nails by up to 50% when used in conjunction with standard scraping tools. There is also the risk of nail infections, which usually occurs because the skin or cuticle around the nail is damaged.

In general, experts say that people who do their own acrylic nails or visit a salon occasionally are under minimal health risks. Technicians, however, are exposed to a much greater degree to the chemicals and dust particles associated with nail care and art, so medical professionals and certification agencies usually advise them to take additional safety precautions. This includes basic steps such as ensuring the salon is well ventilated, wearing a dust mask and not eating or drinking at the work areas.
