Hand Sanitizer Spray
I am formulating a hand sanitizer spray but the overall pH is too high. Approx 9. How can I reduce the pH? The formula in weight is as follows:
Denatured Alcohol (96.11%) - 59.00
Water - 17.00
Isopropyl Alcohol - 5.00
Glycerine - 2.00
Propylene Glycol - 1.00
Isopropyl Myristate [IPM] - 1.00
Triethanolamine [TEA] (99%) - 0.75
Is the TEA required? I noticed the IPM “floating” at the top of the solution until I added the TEA. Can I use Polysorbate 20 to incorporate the IPM?
