Science
Mechanism of Action
This ingredient acts as a 'pseudo-F layer' by replicating the function of 18-methyleicosanoic acid (18-MEA), the essential lipid found on the outermost surface of the skin and hair. Its cationic (positively charged) nature allows it to selectively adhere to negatively charged damaged sites, creating a breathable, water-repellent film that reinforces barrier integrity and minimizes transepidermal water loss.

Clinical Evidence

Key findings
- 01 Clinical evaluation demonstrates that concentrations between 1.0% and 5.0% provide symptom relief for atopic dermatitis comparable to 1% hydrocortisone, significantly lowering SCORAD scores.
- 02 Technical data indicates that usage levels as low as 0.6% effectively restore the hydrophobic F-layer, leading to measurable improvements in barrier function and hydration retention.
Transparency
Dusting Analysis
Because it is a specialized technical ingredient often sold under trade names like Vegetamide, it is frequently used at 'label claim' levels (under 0.1%) rather than the 0.6%–1.0% required to actually repair the lipid barrier.
The Formula
Formulation
Stability
Maintains peak efficacy in slightly acidic to neutral environments; extreme alkaline conditions can degrade the cationic charge necessary for its targeted repair mechanism.
Synergies
- Glycerin
- Xyloglucan
- Ceramides
Conflicts
- High concentrations of anionic surfactants
- Strongly alkaline solutions
Safety
Safety Profile
Classified under the 2016 CIR assessment of plant-derived peptides; it is generally non-irritating and well-tolerated by sensitive skin types.
