Description

Cyclopentadecanolide is a high-purity macrocyclic musk lactone, also known as Exaltolide. This compound is valued for its exceptional olfactory profile, characterized by a powerful, clean, and long-lasting musky scent with subtle floral and animalic nuances. It is a fundamental building block for perfumers and flavorists seeking to create sophisticated, stable, and substantive fragrance accords. Key industries that rely on this material include fine fragrance, personal care, and household product manufacturing.
