Synthetic violet that captures orris elegance
Isoraldeine 70 is approximately 70% Gamma-Methyl Ionone, a compound that mimics the scent of fresh violets at a fraction of natural orris cost.
Origin
Switzerland
The development of Isoraldeine traces to the broader synthetic aroma revolution of the late 19th and early 20th centuries. As perfumers gained access to aroma compounds created through organic synthesis, materials like coumarin and vanillin opened new creative territory.
Methyl ionone, first synthesized in the 1890s, provided perfumers with a stable, affordable violet-iris note. Givaudan's Isoraldeine, introduced as a trademarked specialty, refined this chemistry further.
The molecule allowed perfumers to introduce the prized orris-violet character into compositions without relying on expensive natural iris butter, which requires years of maceration. Today, Isoraldeine remains a workhorse ingredient in both classic and contemporary fragrances, valued for its versatility and consistent olfactory profile.
