Cashmeran (CAS 33704-61-9) — Musky Heart Note Fragrance Ingredient
Cashmeran
CAS 33704-61-9
What Is Cashmeran?
Cashmeran is a modern synthetic musk used in luxury perfumes and fabric softeners. It creates a warm, velvety scent reminiscent of cashmere wool. This ingredient matters because it provides long-lasting softness to fragrances without using animal-derived musks, making it both luxurious and cruelty-free.
Safety Profile
GENERALLY SAFEWhat Does Cashmeran Smell Like?
Cashmeran unfolds like a luxurious textile – initially crisp with a peppery sparkle that quickly softens into warm suede and wood tones. The heart reveals a plush, musky character with subtle ambery undertones, while the dry-down lingers as a skin-like musk with whispers of cedar and vanilla. Unlike animalic musks, it maintains an airy softness throughout its evolution, like cashmere fibers catching light.
Scent Profile
In Famous Fragrances
Fragrance associations may not reflect actual formulations.
Used as a modern musk alternative to create the fragrance’s signature suede-like texture, blending with iris and cocoa for a contemporary masculine elegance.
Showcases Cashmeran solo to demonstrate its full spectrum from peppery top notes to velvety dry-down, creating a ‘your skin but better’ effect.
Provides warmth and diffusion to the dark floral composition, acting as a bridge between the patchouli base and truffle accord.
Contributes softness to the gourmand structure, rounding out the sharpness of patchouli with its textile-like musk character.
Used to amplify the wood notes while adding a skin-scent dimension that makes the fragrance more wearable.

Chemistry, Properties & Perfumer Guide
The Chemistry
Cashmeran belongs to the indane chemical class, specifically a trimethylindane derivative. While not found in nature, its structure mimics certain woody-musky compounds from natural sources. Industrial synthesis typically begins with petrochemical precursors through Friedel-Crafts alkylation reactions. The molecule’s rigid indane framework contributes to its stability and longevity in formulations. Unlike traditional musks, it lacks the polycyclic structure that causes environmental persistence issues.

Classic Accords
Tip: Use below 5% to avoid overwhelming other notes; excels when paired with ionones for softness.
Alternatives & Comparisons
A macrocyclic musk with similar softness but more floral character; preferred when needing greater diffusion.
Stronger traditional musk for formulations requiring more projection and less woody character.
More animalic musk alternative when seeking greater sensuality in the dry-down.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. IFRA, REACH, EU Cosmetics Regulation standards update periodically. Consult current IFRA Standards Library before formulating. Not legal or regulatory advice.
IFRA Status
No IFRA restrictions; approved for all categories under Amendment 49.
RIFM Assessment
Evaluated by RIFM in 2015 with no significant safety concerns at current usage levels.
Sustainability
As a synthetic material, Cashmeran avoids the ecological issues of natural musk harvesting. Its production doesn’t require endangered species or extensive land use. The molecule’s relatively simple structure makes it more biodegradable than traditional polycyclic musks, though proper wastewater treatment is still recommended during manufacturing.
