Benzaldehyde

Other names: phenylmethanal

Harm score: 4 (Slightly harmful chemistry)

Benzaldehyde, also known as phenylmethanal, is an organic substance belonging to the aromatic aldehydes. It is characterised by a pungent, sweet almond odour, which makes it widely used in perfumery and the food industry. Its many applications include, for example, the production of fragrances and food additives, and it is often used to mimic the smell and taste of almonds.

Despite its presence in the food industry, it is important to stress that in its pure form benzaldehyde is toxic. It must therefore be handled with care. In higher concentrations, it can cause irritation to the skin, eyes and mucous membranes. However, in small quantities it is safely used as a component of many products we consume on a daily basis. In fact, benzaldehyde is an essential ingredient in artificial fruit essences, especially those with an almond or peach flavour, and is found in confectionery, sweets and some drinks, for example. It can also be found in perfumes or cosmetic products thanks to its intense and pleasant scent.
