Descriptions

Comment (FraterWork)

This material demonstrates the fundamental principle of aldehydic perfumery: power through dilution. Neat, it appears harsh and fatty with fermented fruit and wine-lees character. But diluted to 1% or less, it transforms into the quintessential aldehydic sparkle that revolutionised 20th-century perfumery. The aldehydic lift effect is irreplaceable—it cuts through dense florals, resins, and animalic notes, making them feel lighter and more effervescent. This is the "rocket fuel" that launches fragrances from the bottle with that characteristic "whoosh." Its green, herbaceous, and ozonic facets provide freshness whilst the aldehydic power creates radiance. Use this when you need to transform heavy compositions into something brilliant and sparkling. Essential for white florals like hyacinth and ylang-ylang, and perfect for creating that classic aldehydic bouquet when blended with other C8-C12 aldehydes. The key is extreme precision—overdosing creates harsh plastic effects. aromachem Best Seller
