Adding Essential Oils to Dr. Bronner’s Baby Unscented Pure-Castile Liquid Soap 

If you’ve been dreaming of combining your favorite scent with Dr. Bronner’s, then our Baby Unscented Pure-Castile Liquid Soap is the place to start. It contains no essential oils and double the amount of olive oil, making it especially moisturizing and nourishing to the skin. We suggest only adding to our Baby Unscented Soap as adding essential oils to our scented soaps may cause them to cloud or thicken

Note on Essential Oil Amounts: The amount of essential oil you need to add to the Baby Unscented Castile soap will vary because every type and brand of essential oil is unique and some are stronger than others. We encourage you to experiment until you find a recipe that works for you. 

Mild Essential Oils 

Here are types of essential oils that many characterize as having a mild scent, so they will require a few more drops to get the desired effect: Chamomile, jasmine, geranium, neroli, Ylang-Ylang, petitgrain, angelica root, clary sage, fennel, hyssop, rosemary, thyme, parsley
  • 2 oz. bottle of Baby Unscented: Add about 30 drops
  • 4 oz. bottle of Baby Unscented: Add about 60 drops
  • 8 oz. bottle of Baby Unscented: Add about 120 drops
  • 16 oz. bottle of Baby Unscented: Add about three quarters of a 10 mL bottle
  • 32 oz. bottle of Baby Unscented: Add about a full 15 mL bottle

Strong Essential Oils 

Here are essential oils characterized as being on the stronger-scented side that will likely require fewer drops: Cedarwood, camphor, cajeput, eucalyptus, patchouli, pennyroyal, laurel leaf, lavandin, spearmint, wintergreen, basil, cinnamon, pine
  • 2 oz. bottle of Baby Unscented: Add about 10 drops
  • 4 oz. bottle of Baby Unscented: Add about 20 drops
  • 8 oz. bottle of Baby Unscented: Add about 40 drops
  • 16 oz. bottle of Baby Unscented: Add about 80 drops, or about half a 5 mL bottle
  • 32 oz. bottle of Baby Unscented: Add about 160 drops, or about a full 5 mL bottle
Please experiment with these amounts to get the desired outcome. It’s best to start out adding lower amounts and test since it’s easy to add more if you want a stronger scent.

How to Mix the Essential Oil(s) with the Castile Soap

Once you’ve settled on an essential oil, you can mix directly into the Baby Unscented. Mixing directly might lead to some separation between the oils and the soap, so you'll want to give it a good shake before each use. If you want to avoid separation altogether, here are a few mixing tips! 
  • Heat the soap in a stainless-steel pot over low heat for about 5 minutes
  • Add the soap and oil(s) together in an immersion blender
  • Blend for 1 minute
  • Stir occasionally while soap cools
  • Once cooled, pour blended soap into a bottle

Additional Mixing Tips

  • Using higher amounts of essential oils can lead to consistency issues and/or cloudiness. We recommend adding a few drops at a time, being sure to check for any consistency changes as you go. If your soap begins to thicken, distilled hot water can be added a few drops at a time thin the product back down until desired consistency achieved.  
  • Be careful when handling hot soap (take the same precautions as handling hot soup). We recommend holding the immersion blender upright so as not to spill any hot soap. 
  • When heating your soap over low heat, be sure to avoid going over the low heat on the stove or ~145F.
