It is responsible for the lemon odor in citronella candles.
is the main component of the mixture of terpene compounds that gives citronella candles their distinctive lemony odor. Citronella oil is extracted from citronella grass (Cymbopogon nardus), which is native to India and southeast Asia. This oil is used as a fragrance in soaps and mosquito-repellant candles. Citral or 3,7-dimethylocta-2,6-dien-1-al or lemonal C10H16O is a chemical compound and part of the terpene family. ...

Citronellal is actually present at higher levels in the Java type.
Because of its high citronellal content (up to 50% of the total volume), and geraniol (up to 45% of the total volume), it's often used as a starting point for perfume materials which are isolated or fractionated from the oil.
Citronellal and geraniol are two of the most important and widely used perfume building blocks.
This reaction causes the cyclization of the citronellal to produce an impure mixture of 40-45% cis and trans p-menthane-3,8-diols and is essentially the method disclosed in J. Am.
It is believed that by removing the unreacted citronellal and other low boiling point compounds, synergism between the p-menthane-3,8-diols and these acetals was able to be observed as the low boiling point compounds did not interfere by displacing the p-menthane-3,8-diols and/or acetals from the repellent air layer formed immediately above the skin.
One might therefore expect that a mixture of citronellal and p-menthane-3,8-diols would have an enhanced repellency but this was found not to be the case.
