Beeswax cloths: what should you look out for?

The usual constituents of beeswax cloths are cloth, beeswax, oil and possibly resin.

The cloths used should be textiles that are suitable for food contact. Otherwise, in the case of dyed textiles, such as curtains or other fabric remnants, constituents from the dyes could transfer to the food, for example. The transfer of primary aromatic amines, for example, some of which are classified as carcinogenic, would be critical here. Attention should also be paid to ensuring that the beeswax used meets the requirements as a food additive, since beeswax can otherwise be contaminated with mineral oil constituents or pesticides. The latter can be ingested by the bees when collecting nectar if the plants are treated with plant protection products.

If beeswax-coated cloths come into contact with fatty foods such as pastries, cakes or sausage and cheese, this can cause wax elements to transfer to the food. These transfers are safe from a toxicological perspective provided that only beeswax in accordance with the purity criteria of Regulation (EU) No. 231/2012 is used to coat the cloths.

According to the BfRshort forGerman Federal Institute for Risk Assessment Recommendation XXV “Hard Paraffins, Microcrystalline Waxes and Mixtures of these with Waxes, Resins and Plastics”, the BfRshort forGerman Federal Institute for Risk Assessment recommends that beeswax cloths containing additional substances should not be used for fatty foods.

Conversely, beeswax cloths with waxes containing additional substances are suitable for fruit and vegetables.

Jojoba oil is often used as an oil constituent in beeswax cloths. This is used to increase the cloths’ softness and it is supposed to ensure that the beeswax does not become brittle and peel off the fabric. It is very likely that relevant amounts of jojoba oil will transfer from the beeswax cloths into fatty foods. The BfRshort forGerman Federal Institute for Risk Assessment does not have any applicable long-term studies available, which are necessary for the health assessment of the resulting consumer exposureClose dialogexposureExposureTo glossary according to European food contact material law. The BfRshort forGerman Federal Institute for Risk Assessment does not recommend using jojoba oil in beeswax cloths until the necessary studies for a health risk assessment are available.

Beeswax cloths cannot be cleaned at high temperatures since the coating material would melt. For this reason, cloths intended for reuse should especially not come into contact with raw food produced from animals since pathogens that may be present on these foods can be transferred to other foods if the cloths have not been cleaned properly. Plant-based foods can also be contaminated with pathogens, albeit less frequently. Therefore, although it cannot be completely ruled out, the risk of transmission is lower with plant-based foods.

About the BfR

The German Federal Institute for Risk Assessment (BfRshort forGerman Federal Institute for Risk Assessment) is a scientifically independent institution within the portfolio of the Federal Ministry of Food and Agriculture (BMELshort forGerman Federal Ministry of Food and Agriculture) in Germany. The BfRshort forGerman Federal Institute for Risk Assessment advises the Federal Government and the States ("Laender") on questions of food, chemical and product safety. The BfRshort forGerman Federal Institute for Risk Assessment conducts its own research on topics that are closely linked to its assessment tasks.
