Isodihydrolavandulal 10% Description and usage notes: For most usage this 10% dilution will be a more practical strength to work with. However we also offer the pure, undiluted product for those applications where a dilution is unsuitable.  In that form it’s pretty rank smelling so approach with caution! Lavender aldehyde is one of the key odour character elements in natural lavender oil that makes it smell of lavender, despite being present at very low levels. In fragrances it is an effective booster for natural lavender and can lend a natural aspect to recreations.  It also has, at low concentration, a very attractive refreshing, green note that you wouldn’t suspect from smelling the pure material. Arctander describes, what was then a novel ingredient, like this: “Powerful, herbaceous-resinous, slightly minty odor with woody-Lavender-like undertone and moderate to poor tenacity."
