Science
Mechanism of Action
Functioning as an acidic salt, TEA-HYDROCHLORIDE primarily modulates product viscosity, capable of either increasing or decreasing it depending on formulation requirements. It also acts as a surfactant and provides pH buffering capabilities, particularly effective in solutions around a pKa of 10.75, owing to its protonated amine structure. Its role is foundational for achieving optimal product texture and stability.

Dusting Analysis
No data available regarding TEA-HYDROCHLORIDE as a commonly 'dusted' ingredient, which typically refers to ingredients marketed with exaggerated or unproven claims about direct skin efficacy.
The Formula
Formulation
Stability
As an acidic hydrochloride salt, TEA-HYDROCHLORIDE is stable under normal conditions. It should be stored away from strong bases or oxidizing agents to prevent degradation. Its buffering capacity is most effective around a pKa of 10.75, suggesting utility in high pH formulations.
Conflicts
- strong bases
- oxidizing agents
- N-nitrosating agents (due to potential for N-nitrosamine formation)
Safety
Safety Profile
The CIR Expert Panel deems TEA-HYDROCHLORIDE, and related TEA-containing ingredients, safe for use when precisely formulated to be non-irritating and when free diethanolamine levels adhere to specified limits. It must not be used in cosmetic products where N-nitroso compounds could form. The EU SCCS also considers its use safe under specific restrictions which may include purity criteria, maximum concentration, or product category limitations.
