Triethanolamine uses

Is it safe to use TEA as pH adjuster in products applied to mucous membranes?
The percentage is NMT 0.1%

Thank you for helping.

    As long as you use 99% TEA, not the 85% carrying DEA, I don't see why not, but TrisAmino (tromethamine) from ANGUS is much safer to apply in "those places".
