Exaltolide Oil

Exaltolide Oil is a macrocyclic lactone musk chemically known as ω-pentadecalactone (also called pentadecanolide or cyclopentadecanolide), registered under CAS No. 106-02-5. First discovered in 1930 by Nobel laureate Leopold Ruzicka - whose work on macrocyclic musks was part of the research recognized by his 1939 Nobel Prize in Chemistry - Exaltolide Oil has remained one of the most respected "noble" musks in fine fragrance ever since, valued for a musk character that is closer to natural muscone than most other synthetic musks on the market.

What sets Exaltolide Oil apart in formulation is its dual role as both a fixative and an olfactive modulator: beyond simply slowing the evaporation of other fragrance materials, it actively rounds out a composition, adding skin-warm, powdery-sweet depth with soft floral, ambrette, and faintly animalic-herbal nuances. This is why Exaltolide Oil has been used - historically and today - in landmark fragrances across nearly every olfactory family, typically dosed below 1% but effective up to 5–8% in musk-forward compositions, and why perfumers continue to reach for it whenever a fragrance needs elegant tenacity without a harsh synthetic edge.

As a raw material supplier, we package and ship Exaltolide Oil with batch-consistent olfactive quality, full documentation, and flexible order sizes - from small perfumer trial quantities to bulk industrial volumes - so that whether you are compounding a niche extrait or a large-scale functional fragrance, your Exaltolide Oil performs the same way every time you reorder.

★ Macrocyclic Musk Fixative 

Extremely low volatility gives excellent tenacity, extending the life of a fragrance on skin, fabric, and paper for extended periods.

★ Olfactive Modulator

Rounds and smooths sharp or thin accords, adding roundness, depth, and "bloom" to a finished composition rather than acting only as a passive fixative.

★ Skin-Sensual Effect

Imparts a warm, clean, skin-like musk character that enhances wearability and perceived diffusion of a fragrance once applied.

★ Blending Synergist

Works synergistically with other musks and base notes, allowing lower overall dosage of stronger animalic or nitro-musk materials in a formula.

★ Multi-Family Versatility

Performs across fresh, floral, chypre, amber, and woody fragrance families, making it a flexible base-note building block for a wide range of briefs.

★ Favorable Regulatory Profile

Biodegradable and not currently restricted under IFRA Standards or listed among the EU's declarable fragrance allergens, supporting cleaner formulation compliance.
