Citral is an aromatic chemical, usually appearing as a clear liquid with a sharp lemon odour. This compound appears as a component of some of our fragrance blends.
Citral is a synthetic chemical produced for industry, however it can be found naturally in some plants and plant essential oils, such as orange (Citrus x aurantium), lemon myrtle (Backhousia citriodora) and lemongrass (Cymbopogon flexuosus). It has two isomers (molecules with identical formulas but distinct structures) known as Geranial (Citral A) and Neral (Citral B). This ingredient often appears in fragrances, either as a synthetic additive used to modify the fragrance, or as a natural component of the essential oils used in the fragrance. Interestingly, it has been shown to have some pheromonal effects in insects, and can be used by beekeepers to attract foraging honey bees to a particular location.
Studies indicate a small percentage of people can be sensitive to this ingredient, which is why we list in when it's detected in our fragrances, though it only appears at very low concentrations, within the safe use defined by the International Fragrance Association (IFRA). The IFRA is a self-regulatory representative body of the fragrance industry, dedicated to promoting the safe use of fragrances.
