How to thicken solution containing alcohol
Hi. I want to make a roll on deodorant. I used a spray anti-antiperspirant formula and just want the solution become thick. Below is my formula:
1. Aqua
2. Aluminium Chlorohydrate 50% - 50%
3. Alcohol 96% - 30%
4. PreservativeAt first, i tried using xanthan gum, HEC and sodium alginate to thicken the solution but it doesn’t work. Then, i tried again using carbopol ultrez 20 (Acrylates/C10-30 Alkyl Acrylate Crosspolymer) with TEA and the result still the same, the solution still in liquid state. I checked the pH for both are around 3-4.
Is an alcohol that affect the performance of thickener? how to thicken this formula?
I really appreciate for your reply. thank you.
p/s: im still a beginner 🙂

Xanthan, Ultrez 20, Alginate will not work, they will interact with the Al which is positively charged. HEC you might be able to have some success, please share how you have incorporated that polymer and what specific brand you are using. You can also try HP guar
I should also mention that if you are in the US, anti-perspirant is an OTC and so I wouldn’t recommend making this as a beginner, and certainly not for anything other than personal use.

All of that aluminum ion is going to crash just about any rheological additive in existence save for Veegum or another colloidal clay derivative. Xanthan may work if at high concentration but then you’ll have a gummy mess of a product.
