Dilution Guide for Essential Oil for Safe Use


Nothing is more exciting to make your unique skin care products such as face oil, massage oil, shampoo, cream etc. with your favourite aroma and benefit from the natural goodness of the essential oil of your choice. But before you ever start your organic DIY journey, you need to know how to use your essential oil right.

Never Put Undiluted Essential Oils Directly on Your Skin!

Applying undiluted essential oils onto the skin can be harmful and potentially cause severe skin irritations and allergy reaction that results in an itchy rash. Using a 2% essential oil dilution is considered a safe guideline for topical application of essential oil on adults.  For young children, elderly or people with sensitive skin, it is recommended to cut the dilution ratio in half. When working with small quantities of essential oils, the easiest way to measure is by drops. Although measuring by drops is not the most precise method as different oil varies in thickness, it is acceptable when creating small blends of essential oil for home use. Always remember to dilute your essential oil with a carrier agent before you apply onto your skin, it can be any cold pressed vegetable carrier oil (such as olive oil, coconut oil, or grapeseed oil), vegetable butter (such as shea butter), lotion, moisturiser and natural lipid.

Add essential oil to each 30 ml carrier agent:

  • 2% dilution12 drops of EO
  • 2.5% dilution15 drops of EO
  • 5% dilution30 drops/ 1.5ml of EO

(For facial oil or people with sensitive skin, I suggest 5-10 drops of EO in every 100ml carrier oil)



Approximate Conversation of each Drop of Essential Oil to ml

  • 20 drops of EO = 1ml
  • 100 drops of EO = 5 ml (1 teaspoon)
  • 200 drops of EO = 10ml
  • 600 drops of EO = 30ml
