TL;DR. This ingredient is used as a fragrance material, adding rosy, fruity, green, and slightly citrus facets to perfume blends in beauty and personal care products.
What does Citronellyl Methylcrotonate do in a cosmetic formula?
This ingredient is used as a fragrance material, adding rosy, fruity, green, and slightly citrus facets to perfume blends in beauty and personal care products.
Is Citronellyl Methylcrotonate clean?
From a clean-beauty perspective, it sits in the fragrance category, so the main questions are sensitization potential, IFRA compliance, and disclosure within the formula’s fragrance system. It is not a broad restricted-list staple, but fragrance ingredients generally carry more scrutiny than basic moisturizers, emulsifiers, or solvents.
Is Citronellyl Methylcrotonate sustainable?
This material is typically made through ester chemistry using terpene-derived alcohol feedstocks that may be plant-derived or synthetic, depending on supplier route. As an ester, it is expected to be more biodegradable than persistent silicone or fluorinated materials, but sustainability depends on feedstock origin, manufacturing documentation, and fragrance-house data.
Is Citronellyl Methylcrotonate COSMOS-approved?
It is not generally accepted as a standalone synthetic fragrance material in COSMOS-natural or COSMOS-organic formulas, though it may fit only if supplied as part of a compliant natural fragrance system with the right documentation. Its Green Chemistry profile is best when made from renewable terpene feedstocks with efficient esterification and good biodegradability data.
How does Citronellyl Methylcrotonate work chemically?
The molecule is a hydrophobic fragrance ester formed from a terpenoid alcohol and an unsaturated branched acid component, which gives it low water solubility and good compatibility with oil phases and perfume concentrates. It is normally used at trace fragrance levels in finished products, and like many esters it can be less stable under strongly acidic or alkaline conditions where hydrolysis becomes more likely.
