Description
Cyclopentanone (CAS 120-92-3) is a cyclic ketone also known by the trade names Dumasin and Adipinketon, and registered under FEMA 3910. It carries no E-code designation. The compound is recognised under REACH regulations and listed in standard flavour and fragrance inventories across the EU.
In food flavouring, cyclopentanone contributes caramel-like and minty top notes to confectionery and baked goods by interacting with other carbonyl compounds during formulation. In personal care, it functions as a fragrance modifier, adjusting the odour profile of finished products through its low odour threshold and blending behaviour with musks and florals.
Cyclopentanone is supplied as a liquid in compliance with FCC (Food Chemicals Codex) specifications, supporting use in food-grade applications. It is available under REACH registration for EU supply. Typical packaging includes drums and intermediate bulk containers, with documentation covering purity certificates and safety data sheets aligned to EU GHS requirements.
