Carrot Soap Recipe

Would you ever guess that you could color soap with a natural vegetable ingredient: carrots? No? If you want to find out how, read this post and follow the recipe! Try this basic recipe for a homemade natural carrot soap, scented with a citrus aroma and naturally colored with carrot pureé!

In the first recipes presented on this blog, only an oil/fat was used per recipe: see Homemade Olive Oil Soap Recipe, Homemade Coconut Oil Soap Recipe or Homemade Lard Soap Recipe.

Healthy Carrot

No one will ever question if carrots are good for your health. It’s common knowledge. The carrot (Daucus carota) is a root vegetable often claimed to be the perfect health food.

It is crunchy, tasty, and highly nutritious. Carrots are a particularly good source of beta carotene, fiber, vitamin K1, potassium, and antioxidants. They also have a number of health benefits. They’re a weight-loss-friendly food and have been linked to lower cholesterol levels and improved eye health. What’s more, their carotene antioxidants have been linked to a reduced risk of cancer.

Orange carrots get their bright color from beta carotene, an antioxidant that your body converts into vitamin A. Filled with vitamins, anti-oxidants and a natural colorant – beta-carotene – it’s a great, and common, ingredient in natural soaps. While some vitamins might be destroyed by the saponification process, I can assure you that beta-carotene does turn your soap yellow, just check out the picture below.

What You Can Find In This Recipe

The oils and butters used in this recipe are:

  • Olive oil – very conditioning and smoothing for the skin
  • Coconut oil – makes a soap hard and very cleansing
  • Castor oil – also cleansing but mostly improves foam
  • Sunflower oil – rich in vitamin E and very conditioning, and cheaper than the other oils
  • Shea butter – very conditioning as well and full of vitamins: A, E and F and antioxidants.

We will also use carrots as our natural colorant (yes, you guessed… and nevermind that I might have mentioned 3 times by now). Beta-carotene will give your soap a color between pale yellow to dark yellow/almost orange, depending on the amount of carrots used in the recipe and its quality. There will be no carrot aroma, and the carrot’s properties as a vegetable will be mostly destroyed in the chemical process, but the color will stay.

If you wish to change the amount of carrot pureé in this recipe, you will have to reduce the amount of water. Considering the 450g batch, you can adjust the water:pureé ratio as long as you keep the total at 150g.

With a big amount of liquid oils, this recipe will be slow to solidify, so, make sure you use sodium lactate, or even after 7 days, your soap will still be soft.

Get Ready!

  • Wear goggles and gloves! Look at “Safety Recommendations” in the video above or in How to Make Soap From Scratch
    gloves, goggles and maks to safely make soap at home
  • Watch the video above about "Cold Process Soap Making tutorial" or read the post  How To Make Soap by Cold Process Step-by-Step for instructions on cold process soap making before starting. These are generic but important steps for all recipes.

  • Assemble everything: ingredients, equipment, safety equipment. Prepare your workstations. Measure all the ingredients. Don’t start the recipe without having everything ready!
  • Carrot pureé is used as a natural colorant in this soap. It's an optional ingredient. But then again, what's a carrot soap without carrots? 🙂

Prepare the Carrot Pureé

  • Prepare some carrot pureé to add to the lye water: peel and slice a carrot and then simmer it in water (just like preparing boiled carrots). When it's soft, remove it from the water and make the pureé with an immersion blender.

Heat the Oils

  • Heat the oils to melt completely the solid oils.

Prepare the Lye Water

  • The remaining water from the boiled carrot can be used as part of the lye water, but you must use the water ONLY at room temperature.

  • Make the lye solution according to How To Make Lye Water, pouring the carrot purée into the water in the beginning. Mix it until the vapors start to dissipate. The lye water will turn into dark orange-brownish.

Make the Soap Batter

  • Use as a target temperature 40ºC for the oil-lye solution mixture. If necessary, you can reheat the oils, but not the lye solution.
  • Use a strainer to pour the lye water into the oils. The strainer will catch any remaining bits of carrot and lye.

  • Reach trace with the immersion blender.
  • Add after trace ingredients: the extract and essential oil (s). Stir with just a spoon.

  • Optional step – Pre-heat the oven with 40ºC. Turn it off then place the molds inside: the color will be brighter if the molds are heat insulated.

  • Wait 48 hours, keeping an eye on the hardness of the soap.
  • Unmold and let the bars cure for 4 to 6 weeks. See How To Cure Soap for more information.

    A soap recipe colored only with carrot? That’s even possible? I’ve tried and it works!
    Thanks for posting this recipe. Reply
    • Hello and thanks for your comment.

      Yes, it’s possible, natural carrot colors soap with a pretty yellow. I’m so glad you’ve enjoyed this recipe.


  2. It is very thoughtful of you to share this interesting and very resourceful information, if is very helpful to make and it’s been really useful. I always prefer natural products, things that are made of natural components. I’d look forward to having more and more infomercial that are very resourceful and useful like this, thanks for sharing.

  3. Hi there! Thanks a bunch for sharing this wealth of information with me! Can’t imagine the work you put it to pull this together. Carrot soap really helps in Gently removes deep-seated dirt and oil without stripping your skin of its vital moisture, would love to try this recipe out

    • Hello Rorodote and thanks for your comment.

      Actually, I like soap making a lot and researching the net to know how to make soap, although it takes work, yes, it’s hardly an ordeal for me 🙂 

      I am fascinated with the idea that you can color soap with natural ingredients and this is what this recipe is all about. The color you get with carrot pureé is a pretty yellow, unlike the orange tone we would think at first.

      The carrot itself, apart from giving color, little more does to soap, as most of what you add to soap before saponification is destroyed with the chemical process. Still, what you said about this soap – gently removes deep-seated dirt and oil without stripping your skin of vital moisture – is true, also true for most natural soaps. This soap in particular also has wonderful shea butter to make it especially moisturizing and soft.

      Hope you try and enjoy this recipe!



  4. Wow! I love homemade soaps and I would really love to make this! This is going to be a nice project. The curing process is a little long, 30 days. I have no experience with this, so I am guessing that 30 days is normal? What would be the best spot to cure the bars? A dry, shady spot?

    Can I get all the ingredients online?

    • Hello Christine and thank you for your comment.

      Yes, it’s normal for handmade soap bars to cure for 4 weeks (more or less 30 days). It’s a bit of time if you want to try the product right away, but this is worth the wait and 4 weeks actually pass in no time 🙂

      To cure soap, you can check out my article How to Cure and Store Handmade Soap, but yes a dry, shady place is a good one. In addition, it should have good ventilation, and bars should be kept with some space between them.

      As for purchasing the ingredients online, at the bottom of the recipe, you have links that show you where to buy each ingredient and also some of the equipment (about the lastest one, before buying anything, check out what you have in your kitchen already). I am assuming you have carrots and water (preferably distilled) available at home 🙂

      Hope you have as much fun as I did making this soap! Let me know how it went!

      Best Regards,
