RAL Quality Mark for Candles confirmed as a guarantee of freedom from harmful substances
The latest ÖKO-TEST on tealights highlights the importance of the RAL Quality Mark for Candles as a reliable indicator of products free from harmful substances.

In contrast, the RAL Quality Mark for Candles guarantees consistently low levels of heavy metals and toxic organic pollutants, which the test confirmed for most tealights bearing the seal. These performed consistently “very good” and “good” in terms of ingredients. By comparison, 87.5% of the tealights without the RAL Quality Mark showed conspicuous levels of harmful substances.
