Application Overview
Undecanal is a vital ingredient for creating complex, diffusive fragrance structures and is heavily used in consumer products:
Fine Fragrance: It is indispensable in Aldehydic Floral compositions and is used to create radiant, diffusive top notes. It provides a unique waxy-fatty/citrus sparkle that is highly recognizable in classic and contemporary perfumes.
Soap and Detergents: Its excellent stability in alkaline media and high potency makes it a primary choice for scenting laundry powders, liquid detergents, and bar soaps, where it contributes to the perception of 'cleanliness' and freshness.
Cosmetics and Personal Care: Used to add a clean, subtle base note to products like body lotions, shampoos, and room sprays, ensuring a lasting sense of freshness.
Floral Accords: It is key to enhancing and creating specific white floral notes like lily-of-the-valley (muguet) and cyclamen, providing a clean, bright, and slightly metallic facet.
Flavoring: In extremely small, regulated quantities, it can be used to impart certain fatty or citrus notes in confectionery and baked goods (subject to local regulations).
Why Choose Aure Chemical for Undecanal?
Aure Chemical provides Undecanal (CAS 112-44-7) with a commitment to stability, purity, and ethical compliance that is unmatched in the industry.
