Nail polish is a cosmetic product that is applied to the nails to add color and shine. Nail polish formulations may include ingredients that are toxic or affect other health problems. Here are some details about nail polish ingredients and materials:
Ingredients:
-
Resin: The tough material that holds polish together, resin is a type of polymer, meaning it is made of large molecules that string smaller molecules together. Nail polish traditionally requires two types of resin: film-forming and adhesive. The film-forming resin gives the dried polish a shiny texture, while the adhesive polymer adds flexibility, so the lacquer is less brittle. Look for: Nitrocellulose (that’s a film-forming resin) or anything with the words polymer, copolymer, or resin.
-
Solvent: Solvents are used to dissolve the other ingredients in nail polish and make it easier to apply. Common solvents include ethyl acetate, butyl acetate, propyl acetate, and isopropyl acetate. Toulene is an inexpensive (and formerly common) solvent, but is used less frequently now due to talk of health and environmental concerns.
-
Dispersants: These are additives that help pigments mix with the resin and solvent, slowing the process of the color settling and separating in the bottle. Look for: Stearalkonium hectorite, stearalkonium bentonite.
-
UV Stabilizers: These prevent polish from changing color or fading when exposed to sunlight. Look for: Benzophenone, often followed by a dash and the number.
-
Plasticizers: These are added to make the polish pliable and soft. Common plasticizers include dibutyl phthalate, diethylphthalate, and camphor.
-
Dyes and pigments: These are added to give the polish its color. Representative compounds include chromium oxide greens, chromium hydroxide, ferric ferrocyanide, stannic oxide, titanium dioxide, iron oxide, carmine, ultramarine, and manganese violet.
Positive:
-
Nail polish can add color and shine to the nails, making them look more attractive.
-
There are many different colors and finishes available, so people can choose a polish that suits their personal style.
Negative:
-
Some nail polish ingredients are toxic or can cause health problems, such as dibutyl phthalate, toluene, and formaldehyde.
-
Nail polish can be difficult to remove, and nail polish remover can also contain harmful ingredients.
Materials:
-
Nail polish is typically sold in small glass or plastic bottles with a brush applicator.
-
The brush is usually made of synthetic fibers.
-
The bottle and brush are often packaged in a cardboard box or plastic sleeve.
In conclusion, nail polish can be a fun way to add color and shine to the nails, but its important to be aware of the ingredients and materials used in the product. Look for polishes that are free of harmful chemicals, and use nail polish remover in a well-ventilated area to minimize exposure to fumes.
