METHYLCYCLOPENTADECENONE ●
TL;DR. This ingredient is used as a fragrance material, adding a soft, powdery, skin-like scent profile and helping the scent last longer on skin or hair.
What does METHYLCYCLOPENTADECENONE do in a cosmetic formula?
This ingredient is used as a fragrance material, adding a soft, powdery, skin-like scent profile and helping the scent last longer on skin or hair.
Is METHYLCYCLOPENTADECENONE clean?
From a clean-beauty perspective, it has friction because it is a synthetic fragrance component and may be restricted by brands that limit undisclosed fragrance or certain synthetic scent materials. It is not one of the common labeled fragrance allergens, but use is still guided by IFRA safety limits.
Is METHYLCYCLOPENTADECENONE sustainable?
This material is typically made through synthetic chemistry rather than directly from a renewable botanical source. Public biodegradation and supply-chain transparency can be limited, so its sustainability profile is less straightforward than simpler plant-derived fragrance materials.
Is METHYLCYCLOPENTADECENONE COSMOS-approved?
This ingredient is generally not permitted in COSMOS-natural or COSMOS-organic products when used as a conventional synthetic fragrance molecule. Its Green Chemistry fit is limited by nonrenewable feedstock reliance and multi-step synthesis, even though it is used at very low levels in finished formulas.
How does METHYLCYCLOPENTADECENONE work chemically?
The molecule is a large-ring unsaturated ketone, a structure that gives lower volatility and higher substantivity than many lighter aroma materials. In finished products it is normally present only as a trace component within a fragrance blend, often far below 1% of the total formula, with final use governed by IFRA category limits.
