Tonalide Crystals (PFW) - aka Fixolide

Tonalide® Crystals (PFW) — also known as Fixolide® — is a widely used polycyclic musk valued in perfumery for its clean, soft, and diffusive musky character. Its scent profile is typically described as smooth, warm, and slightly sweet, with subtle powdery and laundry-like nuances that contribute a sense of cleanliness and comfort to fragrance compositions.

The material usually appears as white crystalline flakes or powder, and is known for its excellent tenacity and long-lasting presence on both skin and blotter. Once incorporated into a fragrance, it provides a soft musky background that helps round the composition and enhance its overall diffusion.

In practical perfumery, Tonalide® is frequently used to build and support musk accords, while also improving the body, softness, and persistence of a fragrance. It blends especially well with floral, fruity, woody, and amber notes, and is widely employed in many fragrance styles including clean musks, floral bouquets, modern woody compositions, and personal care fragrances.
