Adjusting pre-made Hand sanitizer formula
I have a distributor sending me a couple of barrels of pre-made WHO formula liquid sanitizer. It’s 80% ethynol. I normally just add a gelling agent to it at .5%, and fill it into containers. This time around my client is asking me to turn some of it into surface cleaner by bringing the Ethynol down to 30%. I’m struggling with the math on how to calculate that properly and whether or not it’s ok to just add more distilled water. I’d really appreciate the help. Thanks
