Methylcyclopentdecenone ●
TL;DR. It is a fragrance ingredient that adds a long-lasting, soft base note and helps round out scent accords in leave-on and rinse-off products.
What does Methylcyclopentdecenone do in a cosmetic formula?
It is a fragrance ingredient that adds a long-lasting, soft base note and helps round out scent accords in leave-on and rinse-off products.
Is Methylcyclopentdecenone clean?
Clean-beauty programs treat it as a fragrance constituent rather than a skin-care active, so disclosure and IFRA compliance matter. It is not one of the classic labeled fragrance allergens in many jurisdictions, but scent materials can still be sensitizers for some users.
Is Methylcyclopentdecenone sustainable?
This material is typically produced synthetically, often from petrochemical or mixed synthetic feedstocks, rather than direct botanical extraction. Macrocyclic fragrance ketones are generally viewed as preferable to older persistent fragrance classes, but biodegradation and aquatic-fate data should be checked supplier by supplier.
Is Methylcyclopentdecenone COSMOS-approved?
As a synthetic fragrance molecule, it is generally not compatible with COSMOS-natural or COSMOS-organic unless documented as a permitted natural aromatic under the standard, which is not the usual commercial route. Its Green Chemistry fit is mixed because it has high odor impact at low dose, but common production does not align strongly with renewable feedstock or simple biodegradability principles.
How does Methylcyclopentdecenone work chemically?
The molecule is an unsaturated macrocyclic ketone, a structure class known for low-volatility, substantive fragrance performance. It is used in trace fragrance-dosing ranges rather than as a base ingredient, often below 1% of a finished formula and subject to IFRA category limits.
