What does Alpha-IsomethylIonone do in a cosmetic formula?
This ingredient is a fragrance component used to add violet, powdery, woody notes and improve scent persistence in a formula. It has no primary cleansing, moisturizing, preserving, or emulsifying role.
Is Alpha-IsomethylIonone clean?
Clean-beauty frameworks usually treat this ingredient under fragrance disclosure and allergen policies rather than as a basic functional ingredient. It is an EU-declarable fragrance allergen and is subject to IFRA concentration limits for sensitization management.
Is Alpha-IsomethylIonone sustainable?
This material is typically synthesized rather than directly extracted, with feedstocks that may be petrochemical or terpene-derived depending on the supplier. It is used at very low fragrance levels, but its hydrophobic profile and aquatic-life classification make dose control and wastewater handling relevant.
Is Alpha-IsomethylIonone COSMOS-approved?
As a standalone synthetic fragrance molecule, this ingredient is generally not aligned with COSMOS-natural or COSMOS-organic requirements, which favor natural aromatic materials under defined standards. From a Green Chemistry view, it has some efficiency advantages from low use levels, but weaker marks for renewable sourcing and environmental profile.
How does Alpha-IsomethylIonone work chemically?
The molecule is a lipophilic unsaturated ketone with a methyl-substituted cyclohexene ring and a conjugated side chain, which gives it substantive scent character. In the EU, it must be declared on cosmetic labels when present above 0.001% in leave-on products or 0.01% in rinse-off products, and practical use is further shaped by IFRA category limits.
