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!
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.

- 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.
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.
Molding and Curing
- Pour the dough into the molds using a pitcher and sprinkle with alcohol or witch hazel.
- 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.
