Woody-Ambery Base Enhancer

In fine perfumery, Ysamber K serves as a long-lasting woody amber base, contributing depth and diffusivity to compositions. It blends well with floral, citrus, and green top notes, enhancing longevity and complexity.

Laundry & Fabric Fragrance Booster

Added to detergents and fabric conditioners to impart a subtle but persistent cedar-amber scent. Its thermal and oxidative stability makes it ideal for wash and rinse formulations.

Hair & Personal Care Formulations

Used in shampoos, creams, and deodorants where clean woody tones are desired. Its neutral olfactory profile does not overpower but adds diffusion and lift to the fragrance profile.

Additional Feature

*High Substantivity: Retains detectable odor for over 400 hours on blotter *Modern Replacement: Designed to offer similar performance to Iso E Super with improved sustainability
