How to add natural colorants to soap
Adding natural colorants to soap can be done in a few different ways, depending on the type of colorant and the desired effect. Here are some common methods:
- Mixing into the soap batter: Some natural colorants, such as powders or dried herbs, can be added directly to the soap batter during the mixing process. This method works well for colorants that dissolve easily and don’t clump.
- Infusing into oils: Other natural colorants, such as annatto or calendula petals, can be infused into oils before adding them to the soap batter. To do this, add the colorant to a carrier oil (such as olive oil or sweet almond oil) and let it sit for several hours or overnight, then strain out the colorant and use the oil in the soap recipe.
- Dissolve in water: Some colorants can easily be mixed with water before adding the lye.
- Sprinkling on top: Some soapmakers like to sprinkle dried flowers, herbs, or other botanicals on top of the soap before it sets. This method can add a decorative touch and a pop of color.
When adding natural colorants to soap, it’s important to be mindful of the amount used. Too much colorant can affect the texture and performance of the soap, so it’s best to start with a small amount and add more as needed. It’s also important to choose high-quality, skin-safe colorants that won’t irritate or stain the skin.
