Hello, I bought some Benzocaine HCL powder to mix with some warm water to make a slightly stronger version of orajel for my tooth until I can visit my dentist next month. I got the HCL because I read that its more water soluble, and figured i can use a qtip to swab it around my tooth.
If I wanted to make a 25% solution, how many milligrams of benzocaine powder would I mix if I have 30ml of water?
Thanks!
