We often get asked how many drops of essential oil to use when making small quantities of product for personal use. There is a very simple way of working this out. However many mls you have in the jar or bottle, convert the number to drops and then halve it.
For a bottle containing 100ml of Carrier oil or Lotion, add no more than 50 drops of essential oil.
If the product you are making is for young children or for sensitive skin you should halve this again and use no more than 25drops.
