Natural Colorant Taiwan Swirl

  • Difficulty:Intermediate
  • Time:45 minutes
  • Yields:3 lbs. of soap

This beautiful technique is called the ‘Taiwan Swirl’ because of the first YouTube video that showcased this style of soapmaking. The most difficult part of this recipe is keeping the batter at a light enough trace to get wispy lines. You can change the look of the design by changing the size of the dowel/chopstick/skewer or swirling tool. This recipe used a larger tool and a thin to medium trace to achieve the final product.

Bonus! The new Multi-Pour Sectioning Tool makes it a breeze to separate the 4 colors in this recipe that create the unique design. Scroll down to step 7 to see how to use the dividers.

What You’ll Need:

3.5 oz. Cocoa Butter

8.7 oz. Coconut Oil

10.5 oz. Olive Oil

5.2 oz. Palm Oil

7 oz. Rice Bran Oil

4.8 oz. Sodium Hydroxide

11.5 oz. distilled water

Dark Red Brazilian Clay

Indigo Powder

Activated Charcoal

Titanium Dioxide

Essential Oil Blend: 1.5 oz. Litsea Essential Oil and .6 oz. Spearmint Essential Oil

10″ Silicone Loaf Mold

If you’ve never made Cold Process soap before, stop here! I highly recommend checking out our FREE four part series on Cold Process Soapmaking, especially the episode on lye safety. And if you’d rather do some reading, Bramble Berry carries a wide range of books on the topic, including my newest book, Soap Crafting. You can also checkout the digital downloads for that instant gratification factor.

SAFETY FIRST: Suit up for safe handling practices! That means goggles, gloves and long sleeves. Make sure kids, pets, and other distractions and tripping hazards are out of the house or don’t have access to your soaping space. Always soap in a well-ventilated area.

COLOR PREP: Disperse 1 teaspoon of each colorant into 1 tablespoon of Sunflower or Sweet Almond Oil (or any other liquid oil). Use a mini mixer to get clumps worked out smoothly. Prepping your colors in the beginning will allow you to work quickly and give you more time to work with your soap.

FRAGRANCE PREP: Combine the Litsea and Spearmint essential oils in a glass container and set aside until step 3.

MOLD PREP: Using cardboard, cut three dividers that fit snugly down the center (lengthwise) of the mold. Cardboard brackets on either end can help with stability. If you don’t want to use cardboard, Bramble Berry has a retrofit divider set here for the classic sliding bottom 5 pound mold.

ONE: Slowly and carefully add the lye to the water and gently stir until the lye has fully dissolved and the liquid is clear. Set aside to cool.

TWO: Combine the Cocoa Butter, Coconut Oil, Olive Oil, Rice Bran Oil and Palm oils (remember to fully melt then mix your entire container of Palm Oil before portioning). Once the lye water and the oils have cooled to 130 degrees or below (and are ideally within 10 degrees of each other), add the lye water to the oils and stick blend until thin trace. If you’d like a harder bar of soap that releases faster from the mold, you can add Sodium Lactate to the cooled lye water. Use 1 teaspoon of Sodium Lactate per pound of oils in the recipe.

THREE: When the batter reaches light trace, add the essential oil blend. The Litsea Essential Oil will breakdown the trace, so be sure the batter is fully emulsified before moving on. You may need to stick blend for 10 – 20 seconds.

FOUR: Split the batter evenly into four contains. No need to be exact, but each container should hold about 11 – 12 ounces.

FIVE: Add the dispersed colorants at the following rates:

Stir in the colorants with a wire whisk or spoon.

Quick note: We used cardboard dividers here, but for ease of use the new Multi-Pour Sectioning Tool can’t be beat! This sectioning tool set is perfectly fitted for our 5 Pound Wood Mold with Sliding Bottom. It divides your 5 pound soap loaf into either 3 or 4 sections. Keep in mind it only fits the 5 lb. Wood Mold, so it’s too big for this tutorial. If you want to try the dividers in the bigger mold, simply resize the recipe with the Lye Calculator and set the dividers into the mold.

SEVEN: For now we’ll stick with the cardboard, and for this part you may need to grab a friend. Make sure your center pieces of cardboard are stable and then get someone to help you simultaneously pour the colored batters. Tamp the mold on the table several times once all the soap has been poured, and then slowly lift the cardboard straight up and out of the mold.

EIGHT: Insert a chopstick or dowel down to the bottom of the mold. Then, move it back and forth horizontally through the soap, working your way up the mold.

NINE: Repeat this process, except this time move the dowel up and down vertically.

Allow the soap to sit in the mold for 24-48 hours. When it’s time to cut, you can cut the loaf in the traditional way, but I find that the swirls really shine when I cut the bars horizontally. If you’re not sure how to cut bars horizontally, there’s a video for that here. Cure for 4-6 weeks and enjoy!

    Love it ! On my wish list ( which gets longer).I have your 5 lb mold so will end up ordering it soon:)

  2. Lauri Strain says:

    Titanium Dioxide is on the list of banned ingredients that I got from Whole Foods. Also the State of California has it on a list for ingredients that larger companies have to report using. What is their reason (if you know) for not considering it a natural colorant?

    • Anne-Marie says:

      I don’t see that Whole Foods has titanium dioxide on this list ( for their body care standards? So, I can’t speak to what their concern around body care may or may not be.

      In general, I do know that there is controversy over the use of ‘nano particles’ and often Titanium Dioxide is a nano-particle. Bramble Berry does not use titanium dioxide that is a nano-partice.

      The reason California is concerned about is for inhalation – so only aerosolized products. There is no evidence that it absorbs into skin in normal particle size nor is it a bio accumulator.

      Skin care (leave on) and soap (rinse off) would not apply to the issue around titanium dioxide and being aeorsolized.

      Of course, each and every crafter should make choices for themselves, their family and their customers that they are most comfortable with. For me personally, I’m confident and comfortable using it in my products for myself and my family. The good news is if you have any concerns, it’s not a necessary ingredient for any soap recipe. It just keeps the soap a more white color. =)

  3. Brenda says:

    I too have heard about the recent controversy with titanium dioxide and having been meaning to ask SoapQueen’s take on it.

    On a lighter note, I can’t wait to make this bar. I think I have almost everything, except that new divider. Scent sounds great too. Last time I tried this technique I had a bout of acceleration and I want to try this again.

    • Amanda says:

      Hi Brenda!

      I hope you do give this soap a try, it’s a new favorite of mine! It smells so good :) If you do give it a try, we would love to see a photo on our Facebook page!

      Regarding the question about Titanium Dioxide, the nano particles are the center of the controversy, and Bramble Berry does not use Titanium Dioxide that is nano-particle. There is no evidence that using normal particle sized Titanium Dioxide in soap (a rinse off product) leads to health concerns.

    Instead of doing all that measuring, can we just use your Quick Mix or Swirl recipe? That cuts down on all my measuring mistakes. Thank you so much for the tutorials.


    • Amanda says:

      Hi Rhonda!

      You could certainly use the Quick Mix! Having your oils already measured and ready to go can be really helpful :)

    Would this need to be insulated? for 24 hours?



    • Amanda says:

      Hi Ursula!

      We covered this soap, but did not place it on a heat pad :). I hope you give this recipe a try, it’s such a fun soap and smells amazing!

  6. Nichole says:

    Beautiful soap and the smell is wonderful! I overprocessed before adding the colors. So it was rather goopy putting into the dividers. But it still made into a beautiful soap. I will post some pictures on my website as soon as I can.

    • Amanda says:

      Hi Nichole!

      I’m glad that even though your trace was a bit thick, you were able to save it! :) Can’t wait to see your photos!

  7. Saskia says:

    When you’re using natural colorants infused in oil to do a swirl, do you have to make two batches of soap and use the oil as part of the recipe, or can you split one recipe and then add colorant to one like you would with other colouring processes?

    • Amanda says:

      Hi Saskia!

      So sorry about the delay in response, somehow I didn’t see this comment! You could do either, but splitting the recipe and then adding the colorant would probably be much easier :)

      -Amanda with Bramble Berry

  8. Victoria says:

    For some reason when i do this or any soap for that matter, the soap forms a skin so fast and i cant blend it properly. Its also not thick like i always see in pictures or videos its really watery. (I do this with MP soap) Why is this?

    • Amanda says:

      Hi Victoria!

      Unfortunately, melt and pour soap and cold process soap behave totally differently. Swirls like this are not possible with melt and pour soap, because melt and pour dries very quickly, and you need a decent amount of time to create swirls. If you like the look of cold process soap, I would recommend giving it a try! The blog post below has a large amount of resources for beginners :)

    Hi Ann Marie,
    Thank you for your website, I love all the crafts you are doing. I want to do your moisturizing soap recipes from an old post, your favorite’s. I am not sure when you refer to “palm oil”, whenever you refer to that, is it the same as the “red palm oil”? I have been searching local stores for the “palm oil” but they all say red palm oil. Is it okay to use that for recipes whenever you have “palm oil”? Thanks for your advice.

    • Amanda says:

      Hi Jennifer!

      Palm Oil can be tricky to find in stores. Red Palm Oil comes from the same part of the tree as regular Palm Oil, but is less processed and thus retains its red color. You could use this to make soap, but it will make your soap a reddish/orange color. I have also heard of this oil staining molds, so I would be careful about that :). If you are looking for regular Palm Oil, it is available on Bramble Berry!

      Palm Oil:

      I hope this helps!
