Aldehyde C14

Aldehyde C-14, also known as γ-Undecalactone or Peach Lactone, is a powerful aroma molecule with a soft, creamy, fruity-peach scent. Commonly used in fruity florals, gourmand perfumes, and vintage-style blends, it gives a natural peach skin effect, adding a round, velvety texture and edible sweetness to the fragrance heart.

Aldehyde C-14 is technically a lactone, not a true aldehyde, but is grouped under aldehydes in perfumery due to its fruity-velvety profile and strong impact in trace amounts.
