Science
Mechanism of Action
It functions as a perfuming agent, imparting a floral aroma. As an acetal, it maintains stability in neutral to alkaline environments but can hydrolyze to amyl cinnamal in acidic conditions.

Key findings
- 01 A human skin patch test at 10% in petrolatum showed no irritation or sensitization.
Transparency
Dusting Analysis
As a fragrance, it may be used at very low concentrations, sometimes below effective scent thresholds for marketing or cost considerations.
The Formula
Formulation
Stability
Acetals are sensitive to acid-catalyzed hydrolysis below pH 6.0, which can release amyl cinnamal. It is highly stable in neutral to alkaline systems.
Conflicts
- Strongly acidic environments
- Oxidizing agents
Safety
Safety Profile
While not CIR-reviewed, it's an IFRA-regulated fragrance ingredient. A 10% patch test showed no irritation, but its hydrolysis product, amyl cinnamal, is a known allergen.
