Science
Mechanism of Action
This ingredient functions as a cationic (positively charged) compound that establishes electrostatic bonds with negatively charged substrates, such as hair keratin. It exhibits high-intensity fluorescence when excited by light in the 365–485 nm spectral range, making it highly effective for targeted color deposition and forensic identification.

Key findings
- 01 In vitro research by Ho Y S et al. (2005) demonstrated that at concentrations of 10^-4 M, the molecule can interact with phospholipid membranes to inhibit fatty acid and cholesterol synthesis.
- 02 SCCS/1509/13 safety assessments confirmed that at a 1.0% concentration, the ingredient exhibits minimal dermal absorption and negligible systemic bioavailability.

Dusting Analysis
As a colorant and hair-dyeing agent, concentrations below 0.1% are generally insufficient for visual performance and may indicate label-only inclusion.
The Formula
Formulation
Stability
Maintains peak stability within acidic environments (pH 2.0-5.0). Stability significantly decreases in alkaline conditions. Highly soluble in both aqueous solutions and alcohols like ethanol.
