Tromethamine
A mild base used in small amounts to steady a formula’s pH — often there to turn carbomer thickeners into a proper gel.
What it does
Tromethamine (TRIS) is a mild base used to neutralize acidic ingredients and buffer a formula so its pH stays steady. You'll often see it alongside carbomer-type thickeners, which need neutralizing to gel properly. It is a small-quantity formulation helper, not an active.
The EU’s ingredient database lists it as a pH adjuster (sets how acidic the product is).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
