Making Carrot Soap with Real Carrots

This week I’d like to share how you can add a vegetable puree to your soap.

When I was a beginner soap maker and I first heard of adding vegetable puree’s to soap, I heard that I would have to do a ‘water discount’ to account for the added water to my soap in my puree.  I was just getting familiar with the steps and safety requirements for cold process soap making, and I immediately thought that was too complicated so I dismissed the idea completely. 

But as I practiced and got better, I decided to revisit this idea of water discounting and see what it was all about. It turned out not to be as complicated as I thought.

In my last post I explained the concept of water discounting and why experienced soap makers  usually opt for a water discount in their soaps. Today I’d like to show you how you can use it to your advantage in another practical way by adding a vegetable puree to your soap.

Why are vegetables added to soap?

We all know that vegetables contain vitamins and nutrients that are good for the skin.  No wonder skincare companies highlight the benefits of the fruit and vegetable extracts they include in their formulations. But to be honest, when adding purees to soap, there’s no way to tell how much of these nutrients are still intact after coming in contact with lye. In the end, adding purees to your soap can add some skin loving properties, adds color and makes them a little more interesting.

In today’s recipe I’m going to add carrot puree to my batch.  Carrots are high in vitamin A and antioxidants that can be healing and soothing to itchy, irritated skin.

Here is the Carrot Soap Recipe

As always, please enter this or any recipe in a lye calculator before you try to make your soap batch. Mistakes happen and It’s always better do double check.

If you are new to soap making, I highly recommend my eBook Beginner’s Soap Making Guide that is perfect for beginner soap makers.  I explain exactly what you need to know as a beginner in a step by step, easy to follow format with beautiful pictures and an exclusive video.

Let’s get back to our recipe..Here is what I did:

I took one large carrot, washed it, pealed it, diced it. I filled a small pot with water, added the carrots and brought it to a boil. I let it boil for about 20-30 mins.

I measured out all my ingredients.

When the carrots were cooked and really soft, I threw out almost all of the water and left just enough that I could help mash and puree the carrots. I used my stick blender for this. I used a fork and spoon to mash up as many small chunks as a I could.


Next, I made the lye solution and let it cool near the sink.

Then I warmed the oils in the pot.

My infrared thermometer wasn’t working even though I changed the batteries. I decided to wait about an hour and half to be sure both my lye solution and oils had cooled down enough. (While I was waiting and I placed an order for a new thermometer :) )

After about 90 minutes, I added my Sodium Lactate to the lye solution and stirred. (This step is optional. But since I had such a high percentage of soft oils I chose to add this)

Then, I combined my lye solution with my oils and mixed just until the oils and lye had combined.

I added the Koalin clay to the essential oils to help anchor the scent in the soap. I mixed with the stick blender for about 5 seconds.

Then, I divided my batch into 2 parts approximately 2/3 and 1/3 . I wanted to keep the smaller portion uncolored (white) to add a swirl to the soap.


I started mixing the portion intended for my ‘white’ (1/3 portion) until a semi thick trace was reached.


I added the turmeric and carrot puree to the bigger (2/3 portion) to make this portion orange and mixed with my stick blender until I achieved a semi thick trace.


I poured the ‘white’ in 3 different parts of the bigger part.


Then I used my spatula in an infinity path to blend the colors.


I proceeded to pour the soap into my loaf mold. I ended up with extra and poured the rest into my square molds.


This batch ended up yielding about 8 bars and 4 squares of soap.

It’s recommended that you keep your soap in a well ventilated area and use it within a year. Since I used a water discount, I expect this soap will be ready for use within 3 weeks.  Also, since I used a water discount and added sodium lactate, the soap was ready to slip out of the mold after about 30 hours in perfect shape without any distortions. Win!

I think what I might do next time is keep the soap in a warm oven to prolong gel phase and get some brighter colors.

This soap is great for anyone with sensitive or irritated skin.  Turmeric is anti-inflammatory and healing.
