@luiscuevasii Hello. Could you please give us an update of how did it go after all these years? Did you have any irritation issues? I am facing the same problems as you did back then. I’ve been producing a rollon deodorant with potassium alum. My first batches had a pH of around 3,0 but I had some irritation issues. When I raised the pH = 4,0-4,2 I had no irritation complaints but the deodorant lost its effectiveness (and I lost many of my customers). I am thinking of going to pH ~3.5, which is effective, but I am affraid of the irritation issues. Did you or anyone else know if a pH of 3,5 for a deodorant is safe to use? Considering that the pH of skin is between 4,0-6,0, I am affraid that after long use of an acidic deodorant someone might disturb his skin microbiome. Any help would be appreciated. Thanks.
