L-arginine
Good morning all!
Is L-arginine better than NaOH to bring pH up? Is it helping skin too? It is amino acids.
Thank you so much for answers.

I normally prefer to use L-Arginine, but the two are interchangeable.

I have no idea how can you make L-Arginine work? I mean, if you dissolve it in water it does not a high pH. How can it effect the pH of a final product?
I saw a lot of L-Arginine being used but I never figured out how they do it. It does not bring the pH up. I must be missing something. ?
Thank you!

You have to add quite of bit of it, but it will indeed increase the pH.

@Paprik, L-arginine is added at the end of formulation to bring the pH up. I like it bc it has benefits to skin.

Thank you so much -
Indeed. Arginine is a basic aminoacid with several amino groups able to get hydrogen ions from the media.

@ketchito, thank you for further explaining.

I know from experience it is easier to find L-arginine, and the preparation of NaOH can be difficult depending on conditions. Since using L-arginine, it’s given me less of a hassle during formulating

@plantlab,
Which companies do you suggest to buy l-arginine?thanks and have wonderful holiday

Guess it will depend on what county you live in and where you usually buy your ingredients. In Australia it can be bought at New Directions.
