How do I dilute tea-tree oil to create different concentrations?
Oil is not soluble in water, so you would probably want to dilute it in another type of oil, such as mineral oil. Different concentrations are easy to make. For examples, a 1:2 dilution would be 1ml of TToil in 1 ml of mineral oil. A 1:5 dilution would be 1ml of TToil in 4 ml of mineral oil. An easy way to make many dilutions would be to do a serial dilution: Make a 1:10 dilution (1 ml TToil in 9 ml mineral oil). Then use 1ml of the 1:10 dilution with 9ml mineral oil to get a 1:100 dilution. And repeat this process to get several dilutions with a ten-fold difference.
