Science
Mechanism of Action
This ingredient operates via electrostatic attraction; its permanent positive charge (cationic) allows it to anchor to the negatively charged proteins on the skin surface. Once bound, it forms a biomimetic film that reduces transepidermal water loss (TEWL) while the rice-derived lipophilic groups integrate with the stratum corneum to soften and smooth the skin's lipid barrier.

Key findings
- 01 Demonstrated high skin substantivity and film-forming capabilities that significantly improve skin elasticity and moisture retention.
- 02 Shown to outperform standard hyaluronic acid in moisture retention within rinse-off systems due to its superior surface-binding affinity.
- 03 Displays secondary antimicrobial properties that support a balanced skin environment.

Dusting Analysis
Because it is effective at low concentrations (starting at 0.5%), it is rarely used as a 'dusting' ingredient, though its efficacy in rinse-off products requires at least 1% for measurable surface substantivity.
The Formula
Formulation
Stability
Maintains peak structural integrity and cationic charge in slightly acidic environments, mirroring the skin's natural pH.
