  Tromethamine …. typical method of use….( making a solution for use?)

  Posted by Graillotion on September 18, 2024 at 8:35 pm

  I have Tromethamine on order, as in my latest project…a couple of my ingredients said they conflicted with KOH.

  I have not used Tromethamine before, and selected it over TEA, in that there seems to be some new wave of hate for TEA.

  Have not received it yet….but sounds like it will be a powder. Are people typically hydrating this before use…and what percent solution seems to be the standard (if there is one)? What ingredient is typically used to create the solution…..water?

  Aloha

  Tromethamine usually comes as a powder, and yes, it’s normally hydrated before use. You just dissolve it in water to make pH adjustments easier. A 10% solution (10g Tromethamine in 90g water) is pretty standard, but you can adjust it depending on your needs. Water is best for dissolving Tromethamine—just make sure it’s RO/distilled to avoid any impurities affecting the pH.

  Yes, you will need to dissolve it in water to use. It dissolves easily in a minimal amount of water. Use at similar level as AMP-95. Love tromethamine, can’t understand why others don’t use it either. The thing with TEA is the free DEA inherent when using the 85% concentration TEA. IF using 99% triethanolamine solution, there is no DEA and very little MEA and the CoA must state so.

    Thank you @chemicalmatt for dropping in and rubbing elbows with us earthlings.

    I have made my first foray into the world of Salicylic acid…. which has in turn introduced me to a few ingredients that I had not worked with before.

    The Sytheon rep mentioned it….as well as I had my eye on it for a while….just needed to be pushed.

    Aloha.
