Ecomusk R
Premium Synthetic Ingredient for Perfumery
Ecomusk R is a synthetic alicyclic musk ester developed for modern perfumery and functional formulations. It exhibits a musky, ambrette-like scent with powdery, cottony undertones and dark fruity nuances such as apple and red berries. With over 480 hours of tenacity on blotter and a biodegradability rate of 66.6%, Ecomusk R offers high performance and environmental responsibility in one molecule. It is particularly effective in enhancing fruity compositions and bringing soft diffusion and depth to fine fragrances, fabric softeners, and hygiene applications.

What is Ecomusk R?
Ecomusk R is a newer-generation alicyclic musk ester introduced by Symrise, following the lineage of Helvetolide® and Romandolide®, which themselves derive from structural frameworks of Rosamusk and Cyclomusk. Chemically, Ecomusk R belongs to the family of cycloalkyl esters—macro-like musk odorants with enhanced biodegradability and reduced environmental persistence.
Structurally distinct from polycyclic and macrocyclic musks, Ecomusk R is defined by a rigid, ring-based molecular backbone that enhances stability, olfactory performance, and volatility control. Unlike nitro musks or older polycyclics, it shows low bioaccumulation and aligns with current safety and environmental standards.
Olfactory Profile & Perfumery Applications
Ecomusk R delivers a soft, long-lasting musky signature with nuances of musk ambrette and a cotton-powdery texture. The profile includes:
Musky-Ambrette Base: Offers clean, powdery, and subtly creamy softness.
Red Apple and Fruit Accents: Adds juicy and tart character to top notes.
Velvety, Ionone-like Roundness: Suggests subtle floral fruitiness and depth.
It is used in:
Fine Fragrance: Acts as a long-lasting musk with a soft projection and diffusion profile.
Fabric Softeners: Imparts a clean, warm cotton scent with excellent substantivity on textiles.
Shampoos, Soaps, and Deodorants: Adds creamy musky background and persistence in rinse-off formulations.
Industrial & Technical Uses
Ecomusk R finds applications outside fine perfumery in:
Fabric care (conditioners, boosters)
Personal care (lotions, body sprays)
Home care (air fresheners, diffusers)
Thanks to its high tenacity, diffusion profile, and formulation stability across media (aqueous, alcohol-based, surfactant systems), it suits multi-functional uses.
Regulatory & Safety Overview
IFRA 51st Amendment: No restrictions listed
EU Allergen Status: Does not contain declarable allergens
Toxicological Data: No sensitization or phototoxicity noted under normal usage
Environmental Impact: Biodegradable (66.6%), no PBT/vPvB classification

Always consult manufacturer SDS and REACH dossiers before commercial use.
Additional Information
Ecomusk R debuted publicly at Simppar 2022, introduced by Symrise alongside Globanone. It belongs to a family of musk esters designed for high olfactory performance, sustainability, and regulatory compliance. The development of such molecules reflects a broader industry movement toward green chemistry and non-accumulative synthetic musks, replacing older classes that raised toxicological and ecological concerns.
