About

A pH adjuster and neutralizer used at low percent. PubChem GHS lists eye and skin irritation, so it is suited to rinse-off and tightly buffered formulas only.

Function

BUFFERING

Skin benefits

  • Adjusts pH in cosmetic formulations
  • Can act as buffer or neutralizer
  • Stable in many emulsions

Known concerns

  • GHS-classified eye and skin irritant
  • Aquatic toxicity (H412)
  • Not for leave-on products at meaningful concentration
  • Tertiary amine so much lower nitrosamine risk than DEA but formulation discipline still matters
