Tromethamine

Low risk

FunctionBuffer

What it is — Tromethamine (INCI: Tromethamine) is a pH-adjusting ingredient.

What it does — It is commonly used to stabilize formula pH.

Typical use — It is used in very small amounts to bring a formula to its target pH so the product is stable and skin-comfortable. Getting pH right keeps a product both stable and comfortable to wear.

Who it suits / good to know — Used at trace, neutralized levels as part of the base. It is a processing aid rather than an active. There is nothing to react to at the trace levels used here.

Safety — DHALIORA grades it low risk: inert pH-adjusting buffer (tromethamine/TRIS), well tolerated at the trace levels used. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk - inert pH-adjusting buffer (tromethamine/TRIS), well tolerated at the trace levels used.
How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
