Science
Mechanism of Action
This molecule operates through pH-dependent protonation; when the formulation pH is maintained below 6.0, the amine group gains a positive charge. This allows the ingredient to electrostatically adsorb to the naturally negatively charged surfaces of the skin and hair, forming a uniform monomolecular film that seals in moisture and reduces surface friction.

Key findings
- 01 Clinical assessments of compositions containing 0.5%-5% of this ingredient demonstrated a significant 11.2% increase in fiber diameter and a 9.9% increase in cross-sectional area.
- 02 Persistence testing confirmed that the moisturizing film created by this molecule remains effective and detectable even after 10 consecutive wash cycles.

Dusting Analysis
Because it provides measurable structural benefits at 0.5%, it is rarely 'dusted' at negligible levels; however, its conditioning effects are most pronounced when used between 1% and 5%.
The Formula
Formulation
Stability
Naturally lipid-soluble in its free base form, it transitions to water-soluble when neutralized with organic acids like Lactic or Citric acid. It is sensitive to alkaline environments and becomes unstable at a pH greater than 8.0.
Synergies

- Nitrosating agents
- High pH environments
Safety
Safety Profile
The primary safety consideration is ensuring the purity of the raw material to minimize DMAPA (3,3-dimethylaminopropylamine) levels, a potential sensitizer. It should not be used in formulas that promote the formation of N-nitroso compounds.
