Gamma-nonalactone

Other names: 4-pentyl-gamma-butyrolactone

Harm score: 2 (Derivatives of natural substances)

Gamma-nonalactone, whose other names are, for example, 4-pentyl-gamma-butyrolactone, is a chemical used primarily in food and perfumery. It is an aromatic material with the smell of baked apricots and coconut, which is used to achieve these specific aromas in various products. Outside the food industry, where it is mainly used to flavour soft drinks, baked goods and ice cream, it is also used in perfumery and cosmetics to create original fragrances.

Gamma-nonalactone is produced synthetically but is also naturally present in many organic materials. It is therefore often used in products advertising themselves as 'natural'. With its characteristic fruity and coconutty aroma, it is a valued additive in the food industry. Despite its synthetic nature, it is considered safe for human health. However, it is important to follow the recommended dosage as it can cause adverse effects such as skin and eye irritation if used excessively. In high concentrations, its toxicity may also manifest itself. It is therefore essential to comply with the safety instructions and restrictions laid down for this substance.
