Hydroxyisohexyl3-Cyclohexene Carboxaldehyde ●
TL;DR. This ingredient is a synthetic fragrance material used to add a floral, muguet-like scent profile to perfumes and fragranced personal care products.
What does Hydroxyisohexyl3-Cyclohexene Carboxaldehyde do in a cosmetic formula?
This ingredient is a synthetic fragrance material used to add a floral, muguet-like scent profile to perfumes and fragranced personal care products.
Is Hydroxyisohexyl3-Cyclohexene Carboxaldehyde clean?
From a clean beauty perspective, this ingredient has significant friction because it is a well-documented fragrance sensitizer and is prohibited in EU cosmetics. Many clean retail standards and brand restricted lists exclude it for the same allergy-driven reason.
Is Hydroxyisohexyl3-Cyclohexene Carboxaldehyde sustainable?
This material is synthetic and typically linked to petrochemical feedstocks rather than renewable sourcing. Its main sustainability issue is not land use, but poor alignment with modern biodegradability, transparency, and phaseout expectations for fragrance allergens.
Is Hydroxyisohexyl3-Cyclohexene Carboxaldehyde COSMOS-approved?
It is not permitted under COSMOS-organic or COSMOS-natural standards because it is a synthetic fragrance allergen that is prohibited in EU cosmetics. It also fits poorly with Green Chemistry expectations due to nonrenewable sourcing and unfavorable end-of-life and safety-profile considerations.
How does Hydroxyisohexyl3-Cyclohexene Carboxaldehyde work chemically?
The molecule is an unsaturated aldehyde fragrance compound with a cyclohexene ring, a hydroxyl group, and branched alkyl substitution, which gives high odor impact at very low fragrance-compound levels. The aldehyde and alkene features can oxidize over time, and oxidation products in fragrance mixtures are relevant to sensitization risk, so modern formulations have largely phased it out rather than relying on pH control or stabilizers.
