For a 0.2% dilution:
Convert the percent to a decimal: 0.2 ÷ 100 = 0.002Multiply the number of drops per fl oz (600) by the decimal: 600 drops per fl oz x 0.002 = 1.2 drops (round down to 1 drop).Add 1 drop per 1 fl oz (30 mL) carrier oil
For a 0.5% dilution:
Convert the percent to a decimal: 0.5 ÷ 100 = 0.005Multiply the number of drops per fl oz (600) by the decimal: 600 drops per fl oz x 0.005 = 3 dropsAdd 3 drops per 1 fl oz (30 mL) carrier oil
