Science
Mechanism of Action
This amphoteric molecule adapts its behavior based on the formulation's pH. At neutral levels, it functions as a non-ionic cleanser that emulsifies sebum without stripping; however, at lower pH levels (below 4.5), it transitions into a cationic state, allowing it to bind to negatively charged, damaged areas of the skin and hair to provide targeted conditioning.
Research
Clinical Evidence
Medium confidence1.5%
Key findings
- 01 Demonstrated efficacy in alleviating pseudofolliculitis barbae by improving the delivery of active agents to the follicle at 0.1-3.0% concentrations.
- 02 Shown to provide irritation-free, abundant foam and structural conditioning for damaged fibers in specialized shampoo formulations at 0.5-1.5%.
Transparency
Dusting Analysis
Because it acts as a secondary surfactant and foam booster, concentrations below 0.5% may be used purely for label claims ('dusting') rather than contributing to the structural integrity of the foam or the conditioning profile of the product.
The Formula
Formulation
Stability
Exhibits excellent aqueous stability and acts as a viscosity builder when paired with anionic surfactants.
Synergies
- Anionic surfactants
- Antiseptic agents
- Conditioning polymers
Conflicts
- N-nitrosating agents
- Anionic surfactants at pH < 4.5 (risk of precipitation)
Safety
Safety Profile
Must be formulated to avoid the presence of nitrosating agents to prevent the formation of nitrosamines.
