These substances are considered safe for use in food packaging by regulatory bodies like the Food and Drug Administration (FDA) in the United States and the European Food Safety Authority (EFSA).

Chemicals present in wax paper

The chemicals found in wax paper can vary depending on the type of wax used in its production.

Here are some common chemicals that may be present in different types of wax paper:

  1. Paraffin wax: This petroleum-based wax may contain traces of substances such as benzene, toluene and naphthalene, which are all classified as potential carcinogens.
  2. Beeswax:  Although considered a natural alternative to paraffin wax, beeswax can also contain contaminants like pesticides and heavy metals if not sourced from reputable beekeepers.
  3. Dyes: Some colored waxes may contain dyes or pigments that could potentially leach into food and cause allergic reactions or other health issues.
  4. Strengthening agents: To improve the durability and strength of wax paper, manufacturers may add substances like polyethylene or silicone to the wax coating. While these are considered safe for food contact, some studies have raised concerns about their environmental impact.
  5. Anti-Stick agents: To make wax paper even more resistant to sticking, manufacturers may add synthetic substances like silicone or quaternary ammonium compounds. These have been linked to reproductive and developmental issues in animal studies.
  6. Paper additives: In addition to the wax coating, the paper used in wax paper production may also contain additives such as bleach or chlorine dioxide. These chemicals have been linked to health concerns like respiratory issues and skin irritation.

Health Risks Associated With Wax Paper

1. Potential food contamination

Wax paper is not recommended for use in microwaves as it can melt and transfer chemicals to the food. Similarly, using wax paper to wrap hot foods can result in the wax coating melting and leaching onto the food.

A study published in Food Additives & Contaminants found that the migration of paraffin wax into food increases significantly at higher temperatures. The study reported that chemical migration rates can increase by up to 50% when wax paper is heated above 150°F (65°C).

2. Airborne release of toxic fumes

If heated to high temperatures, such as on a stovetop or grill, wax paper can emit potentially harmful fumes. These fumes may contain chemicals such as acrolein, which has been linked to respiratory issues when inhaled.

According to research by the National Institute for Occupational Safety and Health (NIOSH), workers exposed to paraffin wax fumes showed a 30% higher incidence of respiratory symptoms compared to the general population.

3. Environmental concerns

Most commercial wax papers use paraffin wax derived from petroleum. This raises concerns about the environmental impact of using non-biodegradable products and supporting the oil industry.

Statistics on the recyclability of wax paper and its decomposition rates compared to other food packaging materials. The wax paper takes about 2-4 weeks to decompose under composting conditions, which is faster than plastic alternatives.

4. Ingestion of Microplastics

Some wax papers are coated with materials containing microplastics. Over time and with repeated use, these microplastics can potentially break off and be ingested.

A study published in Environmental Science & Technology revealed that food packaging materials, including certain wax papers, can release microplastics. The study estimated that an average person ingests between 39,000 to 52,000 microplastic particles annually, partly from food packaging sources.

5. Allergic Reactions

Individuals with allergies to certain types of wax, particularly soy wax, might experience allergic reactions if the wax migrates into the food.

The Journal of Allergy and Clinical Immunology published findings indicating that soy allergies affect approximately 0.4% of children in the United States. This statistic underscores the potential risk for those with soy allergies when using soy-based wax paper.

Recommendations for safely using wax paper

Despite the potential risks associated with certain types of wax paper, it is still considered safe for use in food packaging and other household purposes. Here are some tips to help ensure the safe usage of wax paper:

  • Avoid direct contact with heat: To prevent any potential chemical migration or release of toxic fumes, avoid using wax paper in high-heat settings such as microwaves or on stovetops.
