Are Wax Melts Safe During Pregnancy?
Wax melts are a popular home fragrance product consisting of scented wax that is warmed to release aroma. They have increased in popularity in recent years as an alternative to candles, providing fragrance without an open flame [1]. However, there has been little research into the safety of wax melts for pregnant women. This article will analyze the potential risks of using wax melts during pregnancy and provide recommendations to help pregnant women make informed choices. The goal is to comprehensively review available evidence on ingredient safety and provide practical tips for safer use.
What Are Wax Melts?
Wax melts are small cubes or shapes of scented wax that are heated to release fragrance into the air. They are made of wax blended with oils and fragrances, and come in a variety of scents. The wax helps the fragrance oils evaporate into the air more slowly and evenly than liquid oils.
Common ingredients in wax melts include:
- Paraffin wax – This is the main wax base ingredient.
- Fragrance oils – These oils give the wax melts their scent.
- Dyes – Added for coloring.
Wax melts are placed in a wax warmer, which gently heats them just enough to melt the wax and distribute the scent. They are an alternative to candles and a popular way to scent homes. The wax itself does not contain any fragrance – it simply acts as a carrier for the fragrance oils.

Potential Concerns During Pregnancy
When using wax melts during pregnancy, there are a few potential concerns to be aware of. Many fragrances, especially synthetic ones, contain phthalates. Phthalates are chemicals added to help fragrance last longer. Some research indicates that high exposure to phthalates may impact hormone levels and development in utero (1).
Additionally, heating wax releases volatile organic compounds (VOCs) into the air. Studies show that exposure to VOCs can potentially be harmful during pregnancy. It may lead to lower birth weights and other issues (2). The heating element itself also poses a minor fire hazard if left unattended.

Research on Ingredient Safety
There is limited research specifically on the safety of wax melt ingredients during pregnancy. However, some studies have looked at the key components:
Fragrance oils – Essential oils like peppermint, cinnamon bark, and wintergreen should be avoided as they may be toxic to the fetus [1]. Oils like lavender, lemon, and chamomile have demonstrated safety [2].
Paraffin wax – No specific risks have been identified, but paraffin wax melts at a low temperature which reduces any inhalation risk [3].
Dyes – There is minimal research on most dyes. However, food-grade dyes are generally considered safe in small amounts. Brightly colored products should be used sparingly as a precaution.
Overall, there is a need for more research on wax melt ingredients during pregnancy. But following precautions like avoiding risky essential oils, ensuring good ventilation, and using unscented or naturally-scented products can help reduce any potential risks.
Tips For Safer Use
While wax melts are generally considered safe, there are some precautions pregnant women can take for extra peace of mind:
Look for phthalate-free, natural fragrances. Phthalates are chemicals found in some synthetic fragrances that may disrupt hormones. Choosing natural, phthalate-free wax melts can reduce this risk (Source).
Use unscented or mild scents. Strong artificial fragrances may cause nausea or headaches in pregnancy. Opting for lighter scents or unscented wax melts reduces this likelihood (Source).
Open windows for ventilation. Allowing fresh air circulation helps prevent buildup of fragrance molecules. This minimizes any risks and prevents scents from becoming overpowering.
Alternative Options
When looking for safer candle or diffuser options during pregnancy, there are a few alternatives to traditional wax melts to consider:
Beeswax candles are a natural option that does not contain artificial fragrances or paraffin wax. Just be mindful of keeping the wick trimmed to avoid excess soot. Soy candles are another alternative, but make sure they are 100% soy with essential oil fragrance rather than synthetic fragrances.
Essential oil diffusers are generally considered safe during pregnancy when used properly. Some essential oils known to be safe for pregnant women include:1
- Frankincense
- German or Roman Chamomile
- Lavender
- Neroli
- Petitgrain
- Rose or Rosewood
Always dilute essential oils properly and avoid overuse. Check with your doctor about any concerns over specific oils and your pregnancy.
Special Cases
Pregnant women who are considered high-risk may need to take extra precautions with wax melts. High-risk pregnancies include conditions like chronic health problems, advanced maternal age, carrying multiples, or a history of pregnancy complications.
According to community posts, some women with high-risk pregnancies avoid wax melts entirely as a precautionary measure [1]. This is because exposure to any potentially harmful chemicals could pose greater risks for those with underlying health conditions.
Others recommend using only 100% soy wax or beeswax melts scented with pure essential oils, as these are considered safer options. Consulting your doctor is wise if you have a high-risk pregnancy and want guidance on wax melt usage and precautions.
Ask Your Doctor
While wax melts are generally considered safe during pregnancy, it’s always best to consult with your doctor, especially if you have any pre-existing conditions or are considered high-risk.
Your doctor can review the specific ingredients in the wax melts you are using and let you know of any concerns. They may recommend avoiding wax melts altogether during your first trimester when the fetus is most vulnerable.
Doctors may advise avoiding wax melts that contain essential oils, as some oils like peppermint and eucalyptus can stimulate uterine contractions. Pregnant women are also often more sensitive to smells.
If you experience any adverse reactions like headaches, nausea, or dizziness when using wax melts, stop using them and inform your doctor immediately. Your health provider can help determine if the symptoms are related and if additional precautions are needed.
Every pregnancy is unique, so there is no universal guidance about wax melt safety. Having an open conversation with your doctor allows you to make the most informed decision for your individual situation.
The Bottom Line
Most wax melts are considered generally safe for use during pregnancy when used moderately and with proper ventilation. The main risk comes from inhaling large amounts of fragrance oils, which have uncertain effects. The safest option is to use wax melts occasionally for limited time periods. Unscented melts are the least concerning. If using scented wax, select mild/natural fragrances and avoid artificial dyes. Proper ventilation when melting is critical to limit inhalation exposure. Consider alternatives like essential oil diffusers or candles if you have respiratory issues. But while most wax melts appear low-risk, always check with your doctor if you have any specific concerns.
Overall, most research indicates wax melts and their ingredients do not pose major risks for most pregnant women when used in moderation. But consult your doctor if you have asthma, allergies, or other pre-existing conditions for personalized guidance on safe use.
