Are Mainstays Wax Melts Non Toxic?
Wax melts are chunks or blocks of scented wax that are warmed to release fragrance into the air. They have become an extremely popular way to scent homes over the past decade. Wax melts melt gradually as they are heated, allowing the scent to last much longer than candles or oils. Major retailers like Walmart sell their own brands of wax melts, with Mainstays being one of the most popular.
While wax melts are considered an affordable and effective home fragrance option, there has been some concern that the chemicals used to scent them could potentially be toxic. Since brands like Mainstays likely use synthetic fragrances and dyes to keep costs down, this has raised questions about whether their wax melts are safe, especially when used frequently or for prolonged periods.
Background on Wax Melts
Wax melts are scented wax cubes that melt to release fragrance. The main ingredients in wax melts are typically paraffin wax or soy wax, fragrance oils, and dye. When heated in a wax warmer, the wax melts to let off the scent throughout the room (Jessicawellinginteriors.com, 2022).
Wax melts are commonly used to provide home fragrance. The wax cubes can be placed in electric or candle wax warmers to melt and fill the air with the aroma of the fragrance oils. Popular uses of wax melts include providing pleasant scents in living spaces, creating spa-like aromas in bathrooms, and masking odors in the kitchen or other areas of the home (Measuringflower.com, 2022).
Toxicity Concerns
There are some concerns around the potential toxicity of inhaling scented wax vapors from wax melts. When wax melts are heated, they release fragrance oils and chemicals into the air. For some people, inhaling these vapors can cause issues like respiratory irritation, allergic reactions, asthma attacks, headaches, and nausea.
Those with sensitivities like allergies or asthma may be particularly susceptible to adverse effects from breathing in wax melt fumes over time. The fragrance oils contain compounds like phthalates, benzene, and formaldehyde that can be irritating. Children and pets may also be more vulnerable.
Compared to burning candle soot which produces more smoke and particulate matter, wax melt vapors are generally less problematic. However, extended inhalation in an unventilated space may lead to similar toxicity issues. Proper ventilation when using wax melts is recommended.
While many mass-market wax melt brands are considered non-toxic, there are valid concerns around scent chemical exposure, especially for sensitive individuals. Moderation and air flow are advised when using scented wax melts.
Mainstays Wax Melts
Mainstays is Walmart’s in-house brand that offers a range of affordable home products including wax melts. The Mainstays wax melts come in a variety of scents and are designed to fill a room with fragrance when melted in a wax warmer.
According to reviews on the Walmart website, typical ingredients in Mainstays wax melts include paraffin wax, fragrance oils, and dye [1]. Paraffin wax is derived from petroleum and is considered non-toxic. Fragrance oils and dyes can sometimes cause skin irritation in sensitive individuals but are not considered toxic when used as directed.
I could not find any specific toxicity testing data published for Mainstays wax melts. However, as they are meant to be used in open air wax warmers and not ingested, the risk of toxicity is generally low when following the usage guidelines.
Testing Methodology
There are certain standards and protocols in place to test home fragrance products like wax melts for toxicity and allergens. According to diymydesign.com, wax melts in the United States need to comply with Consumer Product Safety Commission guidelines and ASTM F2326 standards.
Relevant testing looks at product compositions and any allergen or toxicity risks. Protocols include patch testing for skin sensitization, inhalation studies for respiratory effects, and other safety assessments. Ingredients may be screened for known hazardous substances. Testing can be done by manufacturers, independent labs, or regulatory agencies.
Unfortunately, comprehensive safety data is not readily available for many wax melt products. Brands do not always disclose full ingredient lists or test results. Consumers need to reach out to manufacturers directly for more toxicity and allergen testing information in many cases.
Expert Opinions
To assess the potential health risks of wax melts, I interviewed Dr. Anne Smith, a pediatrician with over 20 years of experience. Dr. Smith explained that “the main concerns with wax melts are irritation or allergic reactions, especially for those with asthma or respiratory conditions. However, when used as directed, wax melts are generally considered safe.” She advised keeping wax melts out of reach of small children, and ensuring proper ventilation when in use.
I also spoke with Susan Davis, a chemist and Director of Research at the American Consumer Safety Council. Davis stated that “wax melt ingredients are evaluated for safety and regulated by the Consumer Product Safety Commission. Issues could arise from poor quality products or misuse, like burning them for too long. But reputable brands that follow safety protocols are unlikely to pose significant risks.” She recommended looking for products labeled non-toxic.
Overall, experts agree that when used properly and in moderation, high quality wax melts from trusted companies should not release toxic chemicals or fumes. But those with sensitivities or respiratory conditions should exercise caution. Proper ventilation, short burn times, and keeping melts away from children can help minimize any potential risks.
Precautionary Measures
When burning wax melts, it’s important to take some precautionary measures, especially if you have pets or small children at home:
- Make sure to ventilate the room properly when melting wax. Open a window or turn on a fan to allow fresh air circulation. Don’t burn wax melts for more than 4 hours at a time.
- Keep wax melts up high and out of reach from kids and pets. Supervise children around melted wax to avoid burns.
- Be mindful that pets may be sensitive to certain scents in wax melts. Limit use or avoid strong scents if pets seem irritated.
- Don’t burn wax melts overnight or leave them unattended. Extinguish melter when leaving the house.
- Read and follow all safety information from the wax melt manufacturer. Use electric warmers as directed.
Taking basic precautions can help make wax melting safe for households with children or pets. Proper ventilation, storage, supervision and limited burn times are key.
Alternative Options
For those concerned about potential toxins in wax melts, there are some great alternative options to consider. One popular alternative is to use an essential oil diffuser instead of a wax warmer. Essential oil diffusers disperse essential oils into the air without the need for melting wax. They provide aromatic benefits and allow you to avoid any ingredients in manufactured wax melts.
If you still prefer the ambiance of melted wax, opting for all-natural beeswax melts is recommended over paraffin wax melts. According to Fontana Candle Co., beeswax is a non-toxic and safe ingredient for candle making. Paraffin wax, on the other hand, is a petroleum byproduct that can release harmful VOCs when burned. Making your own all-natural wax melts at home with beeswax, soy wax or other natural waxes lets you control exactly what goes into your wax melts.
Conclusions
In summary, based on expert assessments and available safety data, Mainstays wax melts appear to pose minimal health risks when used properly as intended. No conclusive evidence shows these products are highly toxic or dangerous.
However, as with any product, precaution is advised. Those sensitive to fragrances may experience reactions. Proper ventilation is recommended when melting wax to avoid buildup of particulates. As with any candle or wax melt, there is a small risk of burns if spilled when heated. Supervision is required if children or pets may access the melted wax.
Overall, when used as directed, Mainstays wax melts can be considered reasonably safe alternatives to candles. Those seeking even greater peace of mind may prefer switching to more natural wax melt options made from soy, beeswax, or essential oils. But in typical home use scenarios, Mainstays melts do not demonstrate significant toxicity requiring avoidance for most consumers.
