CYCLOPENTADECANONE ●
TL;DR. This ingredient is used as a fragrance material and fixative, adding a long-lasting musky note to perfumes, deodorants, hair care, and body products.
What does CYCLOPENTADECANONE do in a cosmetic formula?
This ingredient is used as a fragrance material and fixative, adding a long-lasting musky note to perfumes, deodorants, hair care, and body products.
Is CYCLOPENTADECANONE clean?
From a clean-beauty perspective, it sits in the broader fragrance category, where transparency and sensitization screening matter more than the molecule itself. It is not a major listed fragrance allergen, but formulas still rely on IFRA-style use limits and disclosure practices.
Is CYCLOPENTADECANONE sustainable?
This material is typically made synthetically, though related musky molecules can occur in nature. Compared with older nitro and polycyclic musk materials, this class is generally viewed as more biodegradable and less prone to long-term bioaccumulation.
Is CYCLOPENTADECANONE COSMOS-approved?
It is not generally permitted in COSMOS-natural or COSMOS-organic products when supplied as a synthetic fragrance molecule. Its Green Chemistry profile is mixed, with relatively favorable biodegradability for a musk-type scent material, but limited renewable-sourcing alignment unless specifically made from accepted natural feedstocks.
How does CYCLOPENTADECANONE work chemically?
The molecule is a large-ring alicyclic ketone with the formula C15H28O, which gives it low volatility and good fragrance substantivity. It is typically used at very low levels in finished products, often well below 0.1%, and is generally more chemically stable than unsaturated fragrance materials under normal cosmetic formulation conditions.
