Should Wax Melts Have Warning Labels?
The popularity of wax melts has surged in recent years, with the global wax melts market projected to reach $450 million by 2030 according to Grand View Research. Wax melts are scented wax cubes or blocks that are warmed to release fragrance. They provide an alternative to candles for home fragrance. However, some consumer advocates argue that wax melts should carry warning labels about potential dangers from chemicals released when heated. This has sparked debate over whether additional regulations are needed to protect consumers.
Health Concerns
Wax melts can release chemicals and fragrances that may pose health risks, especially for those with respiratory conditions like asthma or allergies. When heated, wax melts can emit volatile organic compounds (VOCs) like benzene, toluene, and formaldehyde [1]. Exposure to VOCs can cause eye, nose and throat irritation, headaches, loss of coordination, and damage to the liver, kidneys and central nervous system [2].
One 2023 study found that using scented candles and wax melts was associated with increased respiratory symptoms like coughing, sneezing and shortness of breath. It also found an increased prevalence of headaches after exposure [3]. Those with asthma or allergies may be especially susceptible. The fragrances emitted can also trigger asthma attacks or allergic reactions in some.
While more research is still needed, these initial studies raise concerns over the potential respiratory and neurological health impacts of wax melt use, especially among vulnerable populations. Proper ventilation and limited use are recommended as precautions.
Chemical Components
The main ingredients in wax melts are typically paraffin wax, soy wax, or a blend of the two https://www.ncbi.nlm.nih.gov/pmc/articles/PMC355888/. Paraffin wax is derived from petroleum and may contain volatile organic compounds (VOCs) and carcinogens like benzene and toluene. Soy wax is made from soybean oil and is considered more natural and safer. However, some soy waxes may still contain synthetic fragrances and dyes.
Certain chemical ingredients in wax melts have raised health concerns, especially with long-term exposure to fumes. These include phthalates added as plasticizers, which can disrupt hormones and VOC’s like acetone, limonene, and ethanol that can cause irritation or aggravate asthma https://aromance.ca/blogs/news/unveiling-the-truth-are-wax-melts-toxic. Testing has found elevated levels of some chemicals like benzene in wax melt emissions, but more research is needed on specific health risks.
Current Regulations
There are currently no laws in the United States that require warning labels on wax melts or candles. The Consumer Product Safety Commission (CPSC) provides voluntary guidelines for candle manufacturers to follow, but compliance is not mandatory by law. These guidelines recommend including basic information like the company name, candle weight, and cautionary labeling such as “Keep out of reach of children”, but do not specify requirements for warning labels on specific chemical ingredients.
Other countries do have more strict regulations around candle and wax melt labeling. In the European Union, regulations require disclosing information on energy efficiency as well as listing any hazardous or allergenic ingredients. Canada requires that all consumer chemical products have labels showing the identity, hazards, and safe handling precautions. Specific provinces also have additional rules, like Ontario requiring both English and French on labels. Overall, regulations on wax melt and candle labeling in the US remain minimal compared to other developed countries.

Warning Labels on Other Products
Many similar household products like candles, air fresheners, and cleaning supplies contain warning labels to inform consumers about potential hazards or proper usage. For example, most aerosol air fresheners now include extensive warning labels indicating flammability risks, cautioning against spraying directly at people or pets, and recommending proper ventilation during use.
These detailed warning labels were prompted by increased scrutiny from consumer advocacy groups and government regulators. Over the years, there have been reports of injuries or accidental poisoning from air fresheners, especially among small children and pets. This led to new labeling regulations and voluntary warning labels by manufacturers to promote safe usage.
According to the FPLA, air freshener products must include basic details like the identity of the commodity, name and address of the manufacturer, net quantity of contents, and ingredient declaration. Many companies now go beyond these regulations to proactively warn about flammability, ingestion, misuse, ventilation needs, and allergies (Source).
The increased health warnings for air fresheners provide a precedent that wax melt manufacturers could follow as well, especially given similar concerns about chemical ingredients and safe usage.
Manufacturer Perspectives
Major wax melt manufacturers have mixed views when it comes to requiring warning labels on their products. Some argue that warning labels are unnecessary and could negatively impact sales, while others take a more cautious approach and voluntarily include basic safety information.
According to the National Candle Association, warning labels on wax melts are not legally required in the United States. Most manufacturers choose not to include them because they fear it may deter customers or imply their products are dangerous [1]. The NCA argues wax melts are safe when used as directed and should not require special labeling.
However, some large manufacturers like Scentsy have decided to voluntarily add safety warnings reminding customers to keep wax melts out of reach of children and pets. While Scentsy maintains their products are safe, they include basic precautions to reassure concerned consumers. The impact on sales so far has been minimal.
Ultimately, manufacturer perspectives on warning labels vary. While some aim to avoid alarming customers, others have adopted a more cautious approach to address safety concerns and provide consumers with relevant usage information.
Retailer Perspectives
Major retailers have varying policies when it comes to requiring warning labels on wax melts. According to Candle Science, large retailers like Walmart and Target require labels that list the wax weight in both ounces and grams. Other major retailers like Amazon, Etsy, and eBay do not have specific labeling requirements for wax melts sold through their platforms.
Some retailers have pushed back against requiring additional warning labels on wax melts. They argue that warning labels listing potential health hazards may deter customers from purchasing wax melts, hurting sales. Retailers also point out that no laws currently mandate extra warning labels specifically for wax melts. Since candle products face few labeling requirements beyond listing weight, retailers feel adding more labels to wax melts would be an unnecessary burden.
Consumer Advocate Perspectives
Many consumer advocates argue for the addition of warning labels on wax melts due to safety concerns. Groups like the Consumer Protection Collective have launched campaigns calling for mandatory warning labels, citing the potential fire and burn hazards if wax melts are misused (https://businesslabels.co.uk/product/wax-melt-warning-labels/). They argue that without proper warnings, consumers may be unaware of the risks involved in overheating wax melts or placing them near flammable objects.
In particular, advocates point to the dangers for children if they are able to access hot wax melts. Warning labels could alert parents to keep wax melts safely out of reach. Advocates also note cases of pets being burned by hot spilled wax. Overall, consumer groups believe warning labels are a prudent safety measure to protect households from potential wax melt accidents.
Potential Impact of Labels
Studies have shown that health warning labels on products can influence consumer behavior and reduce health risks. For example, a study published in JAMA Network Open found that octagonal ‘high in’ warning labels on the front of beverage packages were the most effective label format for improving understanding and purchase intent among consumers in Jamaica (https://www.paho.org/en/news/18-4-2023-study-octagonal-warning-labels-most-effective-jamaican-consumers). The study suggests that warning labels may discourage consumption of unhealthy products and reduce associated health risks.
However, some argue that warning labels on wax melts may not be very effective if people don’t perceive them as food items. There are also concerns that warning labels could create an overly alarmist perception of wax melts, since most use fragrance oils that are safe at typical exposure levels. Manufacturers worry that labels may discourage use even when melted properly according to directions. More research is likely needed to determine the appropriate type and placement of warning labels to reduce potential risks without being unnecessarily detrimental to the wax melt industry.
Conclusions
The debate around adding warning labels to wax melts raises valid concerns on both sides. Those in favor argue that wax melts contain potentially hazardous chemicals like phthalates and toluene, so consumers have a right to be informed about any risks. However, manufacturers counter that wax melts already comply with product safety regulations, and warning labels may unnecessarily scare consumers away from a safe product.
Ultimately, while wax melts likely pose minimal risks for most consumers when used occasionally, those with sensitivities or allergies may benefit from a warning about possible respiratory irritation. Clear ingredient disclosure could accomplish this goal without the alarmism of a formal warning label.
As an appropriate compromise, wax melt manufacturers should voluntarily provide full ingredient lists, rather than waiting for regulators to mandate warning labels. This allows consumers to make informed purchasing decisions without stifling business or misrepresenting risks. Retailers can support this effort by giving space on product listings for ingredient disclosure. Such cooperation across the industry is the best path forward.
