Comparative investigations on cold and burning fragrance candles were carried out to identify possible changes of the volatiles caused by the heat of the flame. Headspace analysis of the volatiles of candles with lavender and apple aroma using GC, GC‐FTIR‐MS and a GC‐sniffing technique showed nearly the same combination of volatiles before and after burning of the candles. Only a slight decrease of the concentration of alcohols was found. Fragrance candles can therefore be used in the correct aromatherapeutical sense, because the unchanged biologically active fragrance compounds can be inhaled. The dominating components in the headspace of the lavender fragrance candles (cold/burning) were mainly the terpenes 1,8‐cineole (25.9/25.9%), linalol (10.8/6.2%), linalyl acetate (10.0/9.6%), camphor (8.8/9.6%), lavandulyl acetate (7.0/9.2%) and limonene (6.5/3.3%). The fragrance candles with apple aroma furnished a totally different spectrum of volatiles as no terpenes, but esters of mainly aliphatic alcohols with short‐chain aliphatic acids dominated: 2‐(1,1‐dimethylethyl)‐cyclohexyl acetate (17.7/15.4%), butyl acetate (16.7/20.6%), 2‐methylnonan‐3‐one (5.5/4.9%), propyl acetate (5.4/4.5%), phenyl benzoate (5.2/5.3%), isoamyl acetate (4.9/4.3%), (Z)‐hex‐2‐enal (4.1/5.2%), amyl butyrate (3.8/2.9%), hexyl butyrate (3.6/4.3%), ethyl valerate (3.3/4.2%) and amyl acetate (3.1/2.9%) were found as main constituents (concentration higher than 3%).
