This sheet is about some of the general exposures in nail salon work settings and goes over resources available to help create a work environment with low levels of exposure. This information should not take the place of medical care and advice from your healthcare providers or work safety officers.
What types of hazards might be at the nail salon?
In general, workplace hazards that nail care workers might face include chemicals, dust, bacteria, viruses, and fungus. Muscle strain from working in awkward positions and doing the same motions over and over (repetitive motions) may also be a work stress for salon workers.
What types of chemicals are usually found in the products used in nail salons?
Nail polish can contain pigments, polymers, plasticizers, and solvents.
Polymers that might be in nail salon products can include nitrocellulose and tosylamide/formaldehyde resin (TSF Resin).
Plasticizers in products may include dibutyl phthalate, triphenyl phosphate, and camphor.
Commonly used solvents found in nail products include acetone, toluene, butyl acetate, and ethyl acetate.
Products used with artificial nails include those used to prepare or prime the nail bed (methacrylic acid), adhesives (cyanoacrylate or methacrylate products) and a solvent for removing the artificial nail (often acetonitrile).
Products used in dip powder nails include polymers (like polyethyl methacrylate), and primer for the nail bed (ethyl cyanoacrylate (superglue-like) and benzoyl peroxide, and solvents for removal (acetone, ethyl acetate).
Disinfecting chemicals used to clean tools and soaking tubs.
Formaldehyde gas can be released into the air when using some nail salon products.
How can I learn about the chemicals in the products that I work with in my salon?
The chemicals listed above may not apply to all nail salon workers. To learn about the chemicals that are used at your work site, ask your employer for the Safety Data Sheets (SDS) for each product that you use.
For help on understanding where to find ingredients on an SDS, the Occupational Safety and Health Administration has an example here: https://www.osha.gov/sites/default/files/publications/OSHA3514.pdf
The SDS also describes how to safely use the product and will have recommendations for protective gear like gloves or masks. The SDS will also tell you how to store and dispose of the products you work with. The work site is required to have copies of all the SDS. Most SDS are also available online with a web search. In addition, the employer should provide the correct safety gear (such as gloves and masks) that are recommended by the SDS.
The salon where I work has strong smells. Does that mean I have high levels of exposure?
Nail salons often have a chemical smell. Most chemicals can be smelled long before they would cause a problem for the worker. For this reason, chemical odor cannot be used to tell if you have had an exposure that may be of concern.
Some small studies on air quality in nail salons have found that most chemical concentrations (levels) in the air were below the recommended occupational exposure limits. Occupational exposure limits are created to help keep working adults healthy.
However, many of these air monitoring studies have noticed that formaldehyde levels were higher than recommended for a worker’s respiratory (breathing) health. Methyl methacrylate, toluene, benzene, and other chemicals have also been measured in the air of nail salons. Because exposure to high levels of these can be unhealthy for workers, some states are working on stricter guidelines for keeping salon workers healthy.
Do I only need to be concerned about fumes from the products I work with?
There are different ways that people can be exposed to chemicals.
You can breathe in (inhale) fumes or vapors of chemicals.
Dust created when filing and shaping nails, or when applying acrylic powders, can be inhaled or swallowed. These dusts could contain bacteria or fungus, depending on the health of your client.
Dusts and chemicals can end up on your skin when applying products.
If you eat or drink at work, you could also accidentally get workplace exposures (dust, chemicals, fungus, etc) in your mouth. There are precautions listed below that can help reduce your exposure.
Can working around these chemicals and other exposures harm my pregnancy?
Because all salons are different, the amount of contact with chemicals and hazards can be different among workers. Your level of exposure will depend on the type of services your salon offers, how many hours you work, the kind of ventilation or air system in your workplace, and what kind of precautions you take to reduce your exposure. Just because you work around a possible hazard, it does not mean that you will be exposed to a level that would cause a problem.
Many of the chemicals mentioned above are not well studied in pregnancy. Animal studies have shown that, for some of these chemicals, there might be problems for a pregnancy if the woman who is pregnant is exposed to extremely high levels that cause them to become ill.
I work in a nail salon. Can it make it harder for me to get pregnant?
It is not known if working in a nail salon can make it harder to get pregnant.
Does working in a nail salon increase the chance of miscarriage?
Miscarriage is common and can occur in any pregnancy for many different reasons. It is not known if working in a nail salon increases the chance for miscarriage. Studies looking at pregnancies of nail salon workers have not noticed a higher chance of miscarriage. Some studies on exposure to formaldehyde and chemicals in the organic solvent family have suggested a higher chance of miscarriage for workers with high levels of exposure. Using proper protection and working in a ventilated space will help to reduce exposures.
Does working in a nail salon increase the chance of birth defects?
Birth defects can happen in any pregnancy for different reasons. Out of all babies born each year, about 3 out of 100 (3%) will have a birth defect. We look at research studies to try to understand if an exposure might increase the chance of birth defects in a pregnancy. It is not known if working in a nail salon can increase the chance for birth defects.
Information from animal studies about many chemicals found in nail salons does not suggest exposure will increase the chance for a birth defect. These studies typically do not look at exposure to more than 1 chemical at a time.
A small number of studies looking at the pregnancies of nail salon workers have not found an increased chance for birth defects. In addition, studies on formaldehyde have not reported an increased chance for birth defects. However, other studies on some of the chemicals that are used in nail salons have suggested a greater chance for birth defects among women who have high levels of exposure to chemicals. Using proper protection and working in a ventilated space will help to reduce exposure levels.
One small study suggested those who gave birth to infants with a heart defect were more likely to have worked as a nail technician during early pregnancy than women who gave birth to infants with no reported birth defects.
Studies among women who were pregnant and misusing toluene (sniffing the fumes to get “high”) found effects similar to someone who misused alcohol in their pregnancy.
Does working in a nail salon increase the chance of other pregnancy-related problems?
Most studies on cosmetologists have not reported a greater chance for other pregnancy-related problems like preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces [2500 grams] at birth).
Some studies have reported that workers in salons might be more likely to experience premature rupture of membranes (when the fluid around the baby in the womb leaks out). Some studies have also found a higher chance to develop high blood pressure. Two studies have suggested a possible association with working in a nail salon or as a cosmetologist and having a baby that is smaller than expected.
Overall, it appears that when proper work safety practices are followed, the chance of pregnancy complications would be unlikely to be significantly higher than for women in the general population.
Some products that cosmetologists work with might cause allergy symptoms, such as asthma, or skin reactions. Other hazards in a nail salon, such as bacteria, viruses, fungus, and dusts might also cause problems for a worker’s health. However, these are less likely to affect the developing baby unless you become very sick.
Does working in a nail salon in pregnancy affect future behavior or learning for the child?
Studies have not been done to see if working in a nail salon can increase the chance of behavior or learning issues for the child.
Breastfeeding while working in a nail salon:
The amount of an exposure that can get into breastmilk; and if that exposure could affect a child that is breastfeeding depends on many things, such as: the chemical or product, how high the exposure is, and how often the exposure happens. If you have specific concerns about your work site, discuss them with your healthcare provider or contact MotherToBaby. Be sure to talk to your healthcare provider about all of your breastfeeding questions.
If a man works in a nail salon, can it affect a man’s fertility or increase the chance of birth defects?
Studies have not been done to see if working in a nail salon could affect a man’s fertility (ability to get a woman pregnant) or increase the chance of birth defects. In general, exposures that fathers or sperm donors have are unlikely to increase risks to a pregnancy. For more information, please see the MotherToBaby fact sheet Paternal Exposures at https://mothertobaby.org/fact-sheets/paternal-exposures-pregnancy/.
How can nail technicians lower work exposures?
Your worksite should provide Safety Data Sheets (SDS) on all chemicals used at the worksite. They are also required to provide the proper personal protection for all parts of your job. Be sure to use them, even when not pregnant or breastfeeding.
Following safe work practices and taking precautions to keep exposures as low as possible will be good for you and your pregnancy. These precautions will help all workers, even if they are not pregnant or planning a pregnancy.
Some precautions include:
- Wash your hands before and after working on clients, before eating, drinking, or applying cosmetics, and after handling or transferring products. The Centers for Disease Control and Prevention (CDC) has hand-washing instructions available here: https://www.cdc.gov/ebola/media/pdfs/2024/05/how-to-wash-hands-light-P.pdf.
- Do not eat or drink in your work area.
- Check the product’s Safety Data Sheet (SDS) for specific glove recommendations for each product that you work with. Your work should supply you with the recommended gear. Use the safety gear even when not pregnant or breastfeeding.
- Wear goggles if recommended in SDS.
- Wear the gloves recommended in the SDS.
- These are often nitrile gloves. Latex and vinyl gloves might not provide a barrier for some chemicals. Also remember that gloves never offer a perfect barrier, so wash your hands every time you take off your gloves.
- Wear a dust mask, such as an N95 mask, designed to filter tiny particles. A regular surgical-style mask will not protect you from inhaling very fine dusts. Dust masks do not filter chemicals from the air.
- Cover and protect cuts or cracks in your skin. Damaged skin can increase the chance forexposures.
- If a person is bleeding, do not touch their blood. Ask the person to use a cotton ball or tissue to stop the bleeding and then have them throw it into the trash. Then,havethem put a bandage over the cut.
- Use trash cans that have lids andkeep the lids on the trash cans at all times.
- Keep all bottles and containers tightly closed with their proper lids and caps when not in use.
- Clean and disinfect tools and foot basins after each client, as required by your state’s cosmetology board.
- Talk with your manager or work safety officer to learn what ventilation (air filtering and air moving) systems are in place at your worksite, andask if they are working correctly.
- Get fresh air into your salon. This can be done by having doors and windows open and using any ceiling vents or exhaust systems. If there is no exhaust system then keep the fan, heating, ventilation, and air conditioning (HVAC) system on during work hours (not on auto, which allows the fan to shut off).
- If your salon has manicure tables with built-in ventilation to draw fumes away from you,make sure they are always turnedon. Follow the maintenance schedule for your particular ventilation tables, such as changing the charcoal filters and cleaning out the catch basin as recommended.
- When possible, use products with the least amount of chemicals.
- Do not use products that can release formaldehyde into the air.
- Follow the manufacturers’ instructions onthe label and the Safety Data Sheet onhow to use, how to store, how to clean up spills, and how to dispose of the products.
- Discussvaccines(shots that can help to protect you from getting some diseases) with your healthcare provider. Some might be helpful, such as seasonal flu, hepatitis B, and COVID-19 vaccines.
- Take a short break every hour or so to change body positions. For example, if you aresittingget up and move around for a few minutes. Or if you are standing, sit for a few minutes.
