What is Cashmeran CAS 33704-61-9?

Cashmeran, also called DPMI, is a synthetic polycyclic musk/woody fragrance ingredient with the IUPAC name 1,2,3,5,6,7-hexahydro-1,1,2,3,3-pentamethyl-4H-inden-4-one. Its accepted molecular formula is C14H22O and its molecular weight is about 206.32.

Why does Cashmeran sometimes look solid and sometimes liquid?

Its melting point is about 27 degrees C, so it commonly appears as a white to pale yellow crystalline mass or fused solid at room temperature. Above roughly 30 degrees C it melts to a pale yellow or clear viscous liquid and can be gently warmed for easier handling.

What kind of odor and performance does Cashmeran provide?

Cashmeran has a rich musky, woody, spicy cashmere-like character with floral undertones. It is valued as a base note that links and harmonizes other fragrance materials and gives the formula good diffusion and long-lasting presence.

What are the main industrial applications?

It is used in fragrance compounding for household and industrial scent systems, scented polymer or rubber products, and long-lasting textile finishes. Because it is hydrophobic and alcohol-compatible, it fits well into non-polar or alcoholic formulations.

Does Cashmeran have IFRA restrictions?

Cashmeran is covered by the IFRA standard for DPMI CAS 33704-61-9, so the permitted level depends on the finished-product category and use. Our Premium F&F grade is supplied for use within applicable IFRA category limits, and the final formulation should confirm the specific exposure scenario.

Cashmeran CAS 33704-61-9

Cashmeran (Chemically known as DPMI or 1,2,3,5,6,7-hexahydro-1,1,2,3,3-pentamethyl-4H-inden-4-one) is an iconic, highly substantive synthetic fragrance ingredient. Renowned for its unique, complex olfactory profile that bridges rich musky, woody, spicy, and floral notes, it is widely used as a foundational building block in fine perfumery, luxury cosmetics, and premium fabric care products.

For musk and woody fragrance composition work, see Galaxolide.

Storage & Safety

Storage: Maintain in a cool, dark, and dry environment. Cashmeran may solidify at lower temperatures; gentle warming may be required for homogenization without compromising chemical integrity.
Safety (PPE): Utilize chemical-resistant gloves, safety goggles, and protective aprons. Use only in well-ventilated industrial areas to prevent accumulation of concentrated vapors.

Quality Assurance

Our quality management system integrates Gas Chromatography (GC) and refractive index testing for every batch of CAS 33704-61-9 to confirm isomeric purity and aromatic profile. All production is monitored under strict industrial protocols to ensure the material remains free of contaminants and meets the high-performance fixative requirements of our global partners, with full traceability provided via our COA documentation.
