Science
Mechanism of Action
This alkanolamine neutralizes acidic components like carbomers, forming stable salts to precisely regulate pH. This action ensures emulsion stability and maximizes the efficacy of other sensitive ingredients within a formula.
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Human dermal irritation and sensitization tests at 7% concentration confirmed it is neither a primary irritant nor a sensitizer.
- 02 General use levels in cosmetics (typically <1%) are safe, with evaluations up to 10% demonstrating non-toxicity in practice.

The Formula
Formulation
Stability
Highly stable in alkaline pH environments (neat pH ~10.5), critical for consistent pH and stable neutralization of thickeners. Its volatility can also aid product drying time.
Synergies
- Optimizes pH-dependent ingredients
- Enhances emulsion stability
Conflicts
- N-nitrosating agents
- Isocyanates
- Strong oxidizing agents
- Acid halides
- Anhydrides
Safety
Safety Profile
Formulated up to 7%, it is deemed non-irritating and non-sensitizing. However, it must not be combined with N-nitrosating agents to prevent the formation of carcinogenic nitrosamines.
