However, preliminary studies show that can cause severe skin irritation and allergic reactions, skin depigmentation and loss of nerve sensation. Camphor is the ingredient used to give conventional nail polishes their glossy, shiny appearance.
It is less toxic than the first three ingredients listed above, and is sometimes used in cold remedies such as vapor rubs and nasal sprays. However, the safety of camphor has recently been called into question. It has been shown to trigger severe skin irritation and allergic reactions when applied topically, and inhaling its fumes can cause nausea, dizziness, and headaches.
Observational studies have also linked camphor exposure to organ damage, such as liver dysfunction. Moisturizing Cream. Hand Sanitizer. DBP dibutyl phthalate Dibutyl phthalate DBP , a member of the phthalate family of chemicals, is used in nail polish to minimize chipping. Toluene Toluene is the nail polish ingredient used to create a smooth application and finish.
Formaldehyde Formaldehyde is used to harden and strengthen nail polishes, also serving as a preservative that protects against bacterial growth. Formaldehyde resin Formaldehyde resin is a by-product of formaldehyde that makes its way into many nail polish formulas that include formaldehyde.
Camphor Camphor is the ingredient used to give conventional nail polishes their glossy, shiny appearance.
Formaldehyde can be found in nail polishes, nail hardeners, eyelash glues, hair gels, soaps, makeup, shampoos, lotions, and deodorants, among other products. The two known categories of products with the most formaldehyde are hair straightening treatments and nail hardeners.
What are the dangers of formaldehyde? But that's not very likely with the low levels typically found in cosmetics, unless a person is highly sensitive to the substance, she says.
Plus, low levels of formaldehyde have been found to cause irritation of the eyes, nose, throat, and skin. But the major concern is that formaldehyde causes cancer. These exposures typically do not occur in cosmetic and personal care products. Hair smoothing treatments like the Brazilian Blowout came under fire earlier this year when the federal Occupational Safety and Health Administration warned that its products contained unacceptable levels of formaldehyde.
In some cases, salon workers complained of nose bleeds, eye irritation, and trouble breathing after using the products. In September, the FDA sent a letter to the makers of Brazilian Blowout, stating that the product is "adulterated" with liquid formaldehyde, "which, under the conditions of use prescribed in the labeling," releases dangerous levels of formaldehyde into the air to be inhaled.
When it comes to nail hardeners, formaldehyde is considered a potential threat because it isn't just used as a preservative, as it is in most cosmetics, but as an active ingredient to coat and strengthen the surface of brittle or cracked nails. The FDA does not object if the level of formaldehyde in a nail hardener is 5 percent or less. How much formaldehyde is safe? It depends whom you ask.
While the FDA, which oversees the cosmetics industry, does not prohibit nor regulate the use of formaldehyde in cosmetics except for nail polishes , the Cosmetic Ingredient Review CIR , an independent panel of experts that determines the safety of cosmetic ingredients, recommends that cosmetic products should not contain formaldehyde at amounts greater than 0.
In aerosol products, the CIR recommends that formaldehyde not be used at all. Here is information about some nail product ingredients that people often ask about, or that raise special safety concerns:. Artificial nail removers consist primarily of acetonitrile.
Child-resistant packaging is required for all liquid household glue removers containing more than milligrams of acetonitrile in a single container [16 CFR However, the fact that a product is in "child-resistant" packaging does not mean that a child could not possibly open it. Like any cosmetic product that may be hazardous if misused, it is important for these artificial nail removers to carry an appropriate warning on the label, along with directions for safe use.
Formaldehyde is an ingredient in some nail hardeners and nail polishes. Using these nail hardeners often, however, may make nails brittle and more likely to break or peel. Nail products that contain formaldehyde may also cause skin irritation, as well as allergic reactions to this ingredient. Other nail products contain resins that form a strong coating on the nails, rather than hardening the nails themselves.
TSFR also helps the polish adhere to the nail, adds gloss and helps the product flow well when applied. There is evidence that some people may become allergic to TSFR. Methacrylate Monomers in Artificial Nails "Acrylics". Artificial nails are composed primarily of acrylic polymers and are made by reacting together acrylic monomers, such as ethyl methacrylate monomer, with acrylic polymers, such as polymethylmethacrylate. When the reaction is completed, traces of the monomer are likely to remain in the polymer.
For example, traces of methacrylate monomers remain after artificial nails are formed. The polymers themselves are typically quite safe, but traces of the reactive monomers could result in an adverse reaction, such as redness, swelling, and pain in the nail bed, among people who have become sensitive allergic to methacrylates. In the early s, FDA received a number of complaints of injury associated with the use of artificial nails containing methyl methacrylate monomer.
Among these injuries were reports of fingernail damage and deformity, as well as contact dermatitis. Unlike methyl methacrylate monomer, ethyl methacrylate polymers were not associated with these injuries.
Based on its investigations of the injuries and discussions with medical experts in the field of dermatology, FDA chose at that time to remove from the market products containing percent methyl methacrylate monomer through court proceedings, resulting in a preliminary injunction against one firm as well as several seizure actions and voluntary recalls.
No regulation specifically prohibits the use of methyl methacrylate monomer in cosmetic products. The Cosmetic Ingredient Review CIR Expert Panel determined in that ethyl methacrylate is safe as used when application is accompanied by directions to avoid skin contact because of its sensitizing potential, that is, the possibility that a person might become allergic to it.
Methyl methacrylate monomer is still used occasionally in some artificial nail products, and ethyl methacrylate monomer is used occasionally in acrylic nails.
