Safety and dilution are inextricably linked.

Here are a few key specific oils that have special dilution needs.

To avoid the risk of skin allergy:

  • Clove bud oil should be used at no more than 0.5%
  • Holy Basil oil can be used at up to 1%

To avoid the risk of phototoxicity:

  • Lemon oil should be used at no more than 2%
  • Grapefruit oil can be used at up to 4%
