Alpha-Lonone ●
TL;DR. This ingredient is used as a fragrance material, adding a violet, woody, and powdery note to perfumes, skincare, haircare, and body products.
What does Alpha-Lonone do in a cosmetic formula?
This ingredient is used as a fragrance material, adding a violet, woody, and powdery note to perfumes, skincare, haircare, and body products.
Is Alpha-Lonone clean?
From a clean-beauty perspective, it sits in a middle zone because fragrance components can be disclosure-sensitive and may trigger reactions in fragrance-sensitive users. It is generally used at low levels, with regulatory limits and allergen-labeling rules depending on region and product type.
Is Alpha-Lonone sustainable?
This material can be sourced from natural aromatic fractions or made synthetically, so its sustainability profile depends on feedstock and supplier route. It is expected to biodegrade more readily than persistent silicone or fluorinated materials, but fragrance supply chains should still be checked for renewable sourcing and traceability.
Is Alpha-Lonone COSMOS-approved?
It can align with COSMOS when supplied as a compliant natural fragrance component, while fully synthetic versions may not meet COSMOS-organic or COSMOS-natural fragrance requirements. From a Green Chemistry view, the strongest profile comes from renewable feedstocks, efficient isolation or synthesis, and low-residue processing.
How does Alpha-Lonone work chemically?
The molecule is an unsaturated cyclic ketone in the terpene-derived aroma family, valued for strong odor impact at very low formula levels. It is typically used in trace fragrance concentrations, and formulators manage it within IFRA limits while considering oxidation control, solubility in the fragrance phase, and compatibility with the final product pH.
