Natural Dyes for Soap Making: A Beginner's Guide

Natural dyes for soap making can be a fun and rewarding experience, but it's essential to start with the basics.

You can use a variety of natural ingredients to create vibrant colors for your soap, such as turmeric for yellow, indigo for blue, and pomegranate rinds for pink.

One of the most significant benefits of using natural dyes is that they are generally gentle on skin and the environment.

Turmeric, for instance, has anti-inflammatory properties that can help soothe skin irritations, making it an excellent choice for soap making.

Activated charcoal is a great option for creating deep black or blue colors in soap, but be aware that you'll need to use quite a lot of it to achieve darker shades.

You can use powdered activated charcoal and add up to 3 tsp PPO to liquid oils or to soap at a light trace.

For a more subtle blue color, try using 1 tsp activated charcoal PPO in recipes high in yellow oils.

Activated charcoal can also be used to create a smoky black color when mixed with a small amount of liquid oil before stirring in.

If you're looking for a smoky black color, consider using Black Brazilian ClayKaolin, which can be added to the lye solution or premixed with water and stirred in at light trace.

For a speckled effect, try adding poppy seeds, which can be added at trace and will give a lovely blue-grey to black speckled effect.

Poppy seeds can be rough or exfoliating on the skin, so keep this ingredient for scrubby hand soaps.

Here are some natural dye options for pink and red colors:

Madder root is a great option for creating pink and purple colors, and can be infused in liquid oil or added at trace.

You can also use cochineal to create a dusky pink color, but note that this is not a suitable option for vegetarians or vegans.

For a warm to salmon pink color, try infusing sorrel in liquid oil.

In terms of red colors, it's difficult to achieve a true red with natural soap colors, but you can get close with ingredients like Himalayan rhubarb, cochineal, and Moroccan Red Clay.

Himalayan rhubarb can be infused in a carrier oil and used as a partial or full replacement in soap recipes.

Cochineal can be added to liquid oils or at trace, and can create a range of pink and red colors.

Moroccan Red Clay can be added to the lye solution or premixed with water and added at trace, and can create a range of pink to brick red colors.

Here are some natural dye options for blue colors:

Activated charcoal can create a range of colors from black to soft denim blue, depending on the amount used and the color of the base oils.

Blue Chamomile Essential Oil can be added at trace and will create a blue color.

Cambrian Blue Clay can create a range of shades from soft gray-green to gray-blue, depending on the amount used and the color of the base oils.

Indigo is a great option for creating dark blue or green colors, and can be added to the lye solution, infused in liquid oil, or added at trace.

Natural dyes can be infused into the oil or water you'll be using to make your soap, added directly to the soap before setting, or used in the lye solution.

The type of process you use, whether it's melt-and-pour, cold process, or hot process, as well as the ingredients in your soap, will influence when and how you color it.

It's a good idea to do a test run before adding natural dyes to your soap, especially if you're using a new ingredient.

To make natural dyes, you'll need to gather the right materials, like plant extracts, mordants, and a dye pot.

Start by selecting a natural dye source, such as indigo leaves, turmeric roots, or pomegranate rinds, which can be found in your local garden or a nearby park.

Gather the necessary equipment, including a large pot, a strainer, and a measuring cup, to extract the dye from your chosen plant material.

To prepare the dye, boil 2 cups of water and add 1 cup of the plant material, then let it simmer for 30 minutes to release the dye.

Add a mordant, like alum or cream of tartar, to the dye pot to help the dye bind to the fabric and create a more vibrant color.

For example, using alum as a mordant can produce a range of colors from blue to purple, depending on the amount used.

Once the dye is prepared, soak the fabric in it for several hours to allow the color to penetrate evenly.

Remember to always follow the recommended ratio of dye to water to achieve the best results.

You can use natural dyes in various ways, depending on the type of process you're using. Infuse the colorant into the oil or water before making your soap.

The type of process you use, such as melt-and-pour, cold process, or hot process, will influence when and how you color your soap. This is especially important when using ingredients you've never used before.

Making a small batch of soap before committing to a large batch is a good idea, especially if you're using an ingredient you've never used before. This will allow you to test the colorant and ensure it turns out as expected.

Add the colorant directly to the soap before setting, or use it in the lye solution. Just remember to do a test run first.
