NON-2-ENAL ●
TL;DR. This ingredient is used as a fragrance component, adding a powerful fatty, green, waxy odor note at very low concentrations. It functions as part of a scent blend rather than as a structural formula ingredient.
What does NON-2-ENAL do in a cosmetic formula?
This ingredient is used as a fragrance component, adding a powerful fatty, green, waxy odor note at very low concentrations. It functions as part of a scent blend rather than as a structural formula ingredient.
Is NON-2-ENAL clean?
From a clean-beauty perspective, it carries some friction because small reactive fragrance aldehydes can be sensitizing for certain users and are typically managed under fragrance safety limits. Its acceptability depends on concentration, disclosure context, and compliance with IFRA-style fragrance assessment.
Is NON-2-ENAL sustainable?
This material may be made synthetically or derived from natural lipid oxidation pathways, so sourcing depends on supplier documentation. It is expected to biodegrade more readily than persistent silicones or fluorinated materials, but it is still a volatile fragrance chemical used in trace amounts.
Is NON-2-ENAL COSMOS-approved?
It is not a routine COSMOS-approved standalone input unless it is documented as a compliant natural aromatic material under ISO 9235. Synthetic versions have weaker Green Chemistry alignment, while trace use, biodegradability, and low material intensity improve the overall profile.
How does NON-2-ENAL work chemically?
The molecule is a C9 alpha,beta-unsaturated aldehyde, which explains both its strong odor impact and its higher reactivity compared with many saturated fragrance materials. It is normally used at trace levels in fragrance compositions, and formulators manage it for oxidation, odor dominance, and sensitization potential in the finished product.
