What is crystal nail powder?

- Jul 05, 2017-

Acrylic nail powder is a substance used to produce acrylic nails. It can not be used alone, and can only be hardened with another liquid chemical mixed application. The price of this product is not expensive, you can do it yourself in a nail shop or at home. Crystal nail powder allows nails to look better and provide temporary protection. Although it is generally considered safe, the way to remove acrylic nails means that there is a certain risk of using this product.

The main component of acrylic nail powder is polymethyl methacrylate (PMMA), which is a mixture of two monomers of methyl acrylate (EMA) and methyl methacrylate (MMA). It usually also contains benzophenone (benzophenone-1), in the exposure to ultraviolet light can keep the powder does not bleach. In addition, it contains benzoyl peroxide. In order to meet the fashion needs of consumers, manufacturers also produce added pigment version, the concentration is usually 2%, can make people have a wider range of color options. In addition, some crystal powder also added flash components.


When used in nails, the acrylic nail powder is mixed with a monomer liquid. In addition to avoiding the rapid combination of molecules, but also to prevent yellowing, and let the color evenly spread. In this process, the benzoyl peroxide in the powder acts as a catalyst, allowing the liquid monomer to form a more robust network between the particles, which can cause hard resin.


Under normal circumstances, the nail technician will crystal nail powder and a single liquid mixture with a clean brush applied to the nail. Usually extending from the bottom of the nail to the top, moving outward from the center. Since the chemical reaction causes the two substances to begin to harden at the time of contact, they can not be pre-mixed.

Clear the method

To remove the acrylic nail powder and single-liquid resin, must be soaked with solvent or cover nails. Acetone is the most commonly used, but many people do not like it because it has harmful side effects such as irritating the respiratory tract, causing dizziness and nausea. Remove crystal nails for at least 20 minutes. In order to prevent acetone from causing dry skin, you can apply the skin around the nail before the start of Vaseline.


The safety of crystal nail powder is highly controversial, which may be related to its inclusion of methyl methacrylate. Methyl methacrylate has been banned by the US Food and Drug Administration and other agencies. But this ban only deals with chemical monomer fluids, excluding solids and powders in the polymer. The reason for the latter safety is that its molecules are large and can not penetrate into the skin.
