Science
Mechanism of Action
This ingredient utilizes cationic (positively charged) amino groups that naturally gravitate toward negatively charged damaged areas of the skin and hair, ensuring targeted repair and high substantivity. Its unique molecular structure, featuring long-chain alkoxy and hydroxybutamido groups, forms a silky, water-resistant film that prevents transepidermal water loss (TEWL) without occluding the surface.

Key findings
- 01 Manufacturer data (Dow) indicates significant improvement in hair color longevity and manageability at concentrations between 1.0% and 2.0%.
- 02 Technical profiles suggest levels up to 5.0% for creating breathable protective films that enhance skin texture and hydration.
Transparency
Dusting Analysis
To achieve measurable benefits in barrier support and texture enhancement, a minimum concentration of 0.5% is required; levels below this likely serve only for label claims without providing the characteristic velvety skin feel.
The Formula
Formulation
Stability
While oil-soluble in its pure state, it is frequently utilized as a non-ionic emulsion to facilitate easy dispersion in water-based phases. It maintains structural integrity across a broad pH spectrum.
Synergies
- Glycerin
- Non-ionic emulsifiers
- Other silicones
Conflicts
- Strong oxidizing agents
- Highly anionic surfactant systems (without proper stabilization)
