Tonalid™ (PFW)

Description

A clean and exceptionally tenacious musk character defines this aromatic compound, a pillar of modern perfumery since its development. Its olfactive profile unfolds with a prominent sweet, powdery core, complemented by subtle fruity, berry-like undertones and a warm ambery background. Within fragrance compositions, Tonalid™ (PFW) imparts a remarkable substantivity and acts as a superior fixative, enhancing the longevity of the entire accord while lending a soft, sensual, and clean finish. The material, chemically known as Acetyl Hexamethyl Tetralin (AHTN), is a complex mixture of isomers that together create its signature powerful and radiant effect.

The robust stability and versatile nature of this musk make it an indispensable tool across a wide spectrum of scented products. It is frequently utilized in fine fragrances, personal care items like soaps and lotions, and is particularly valued in functional perfumery, such as laundry detergents and fabric softeners, where its persistence on fabric is highly desirable. Recommended usage can range from a subtle touch to a significant percentage of the formula, depending on the desired effect. The ingredient blends seamlessly with other synthetic musks, such as Galaxolide, and provides excellent support for floral, woody, and ambery notes, adding volume and a sophisticated warmth to the final creation.
