Science
Mechanism of Action
It operates by activating TAS2Rs (type 2 bitter taste receptors), triggering an immediate oral aversion response. In topical applications, it functions as a functional additive that can provide secondary benefits such as viscosity reduction, astringency, and anti-foaming properties.

Clinical Evidence
High confidence0.0006%
Key findings
- 01 Detected at concentrations as low as 50 ppb (0.000005%) in aqueous solutions.
- 02 Achieves effective alcohol denaturation at levels of 0.0006% according to CIR data.
- 03 Becomes intensely unpalatable at 10 ppm (0.001%), effectively deterring ingestion.
Transparency
Dusting Analysis
Because it is effective at parts-per-billion (ppb) levels, very low percentages are functional. It is not an 'active' ingredient in the traditional sense, so low concentrations are expected and necessary for safety.
The Formula
Formulation
Stability
Highly stable in both aqueous and alcoholic solutions; maintains its properties over long periods and is unaffected by light exposure.
Synergies
- Ethanol
- Isopropyl Alcohol
Conflicts
- Strong acids
- Strong bases
- Oxidizing agents (nitrates, chlorine bleach)
Safety
Safety Profile
Classified as safe by the CIR Expert Panel when used as a denaturant. While the raw material is an irritant, it is considered harmless to skin at standard cosmetic concentrations (e.g., 0.0006%).
