1,1,2,3,3-Pentamethyl-2,3-dihydro-1H-inden-4(5H)-one (DPMI)

Cashmeran (DPMI) is a synthetic polycyclic musk fragrance molecule developed by IFF (International Flavors & Fragrances), belonging to the indanone chemical family. It is prized for its warm, woody, musky, and slightly spicy-sweet odor profile that evokes the softness of cashmere fabric, making it a popular base note and fixative in fine fragrances, fabric softeners, and personal care products. Formulators choose it for its excellent substantivity, low odor threshold, and ability to impart a luxurious, long-lasting warmth to compositions, though it has faced increasing regulatory scrutiny in the EU due to concerns about aquatic toxicity and limited biodegradability.
