Science
Mechanism of Action
This ingredient functions exclusively as an olfactory stimulant or perfuming agent. It does not engage with skin cell receptors or biological pathways to provide antioxidant, anti-aging, or hydrating effects; its chemical role is restricted to providing fragrance and potentially acting as a skin sensitizer.
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Established as the safe upper limit in fragrance concentrates to mitigate risks of systemic toxicity and skin sensitization.
- 02 Determined as the maximum threshold for rinse-off applications, such as bar soaps, to maintain a safe sensitization profile.

Dusting Analysis
As a fragrance component rather than a bio-active ingredient, 'dusting'—the practice of using sub-clinical levels of actives—does not apply here. However, any concentration exceeding IFRA standards (up to 4.0%) represents a safety concern rather than an efficacy failure.
The Formula
Formulation
Stability
Demonstrates stability in neutral formulations like lotions but degrades rapidly in highly acidic (citric acid), alkaline, or oxidative (bleach) environments.
Conflicts
- Strong oxidizing agents
- Strong bases (aldol condensation risk)
- Strong acids
- Bleach
Safety
Safety Profile
Classified as a potential skin sensitizer (H317). Regulated by IFRA Standards with a No Expected Sensitization Induction Level (NESIL) of 5500 µg/cm².

Verdict
A strictly sensory additive that provides a citrus-green scent but offers no therapeutic value and poses a moderate risk of sensitization for reactive skin types.
