About

An aromatic aldehyde derived from agricultural byproducts, used as a fragrance and flavoring agent but restricted to 0.001% in EU cosmetic products.

2-Furaldehyde (furfural) is an aromatic aldehyde produced from agricultural waste (corn cobs, oat hulls) functioning as a fragrance and flavoring ingredient. It is listed in EU Cosmetics Regulation with a maximum concentration restriction of 0.001% in cosmetic products. The SCCS has assessed furfural and found it presents a sensitization risk at higher concentrations. Furfural is also listed as a IFRA restriction fragrance allergen. The low maximum concentration limit reflects concerns about skin sensitization and potential carcinogenic activity at higher doses observed in animal studies.
