Hexadecanolactone
What is Hexadecanolactone?
Hexadecanolactone is a synthetic organic compound predominantly used in the fragrance industry. It is a white, crystalline powder and is part of the lactone family, which are cyclic esters formed from hydroxy acids.
This compound is used mainly for its ability to create a musky or sweet odor, enhancing the scent profile of fragrances in personal care products. Scientific literature does not heavily focus on hexadecanolactone, indicating minimal concern over health effects. However, as with many fragrance ingredients, individual responses can vary.
On a label, hexadecanolactone might not be highlighted distinctly, as it usually functions within a complex blend of fragrance components. Consumers with sensitivities to fragrances should note its presence in cosmetic products.
Commonly found in: perfumes, colognes, body sprays, lotions, deodorants
The FDA does not have specific regulations on hexadecanolactone, treating it generally like other fragrance compounds.
Research on hexadecanolactone is limited, with most studies focused on its usage and safety within the broader category of fragrance ingredients.
Hexadecanolactone is synthetically derived, making it suitable for vegan formulations.

Scout's take
Disclosed macrocyclic musk — the non-bioaccumulative musk class. Rare transparency for a designer house, where musks normally hide inside 'Parfum'.

Disclosed macrocyclic musk — the non-bioaccumulative musk class. Designer formulas typically hide polycyclic musks inside 'Parfum' instead; naming the musk is a genuine transparency and safety win.
