Natural Soap Colorants


There are a wide range of colors that you can achieve when using all natural soap colorants. Spices, Clays, Herbs, etc. are the most natural ways to color your melt and pour soap. One word of warning though – you shouldn’t be expecting bright blues and purples when using these soap colorants You’re more likely to find neutrals, soft warm colors, and lots of greens when using natural soap colorants.

Which Colorants are ‘Natural’?

For the sake of this article we are talking about mostly plant-derived and earth-derived ingredients which will contribute color to your soap. Try to limit the amount of artificial and chemical colors to your soaps so that you can truly advertise a natural homemade soap!

Natural Colorant Benefits

The benefits of using natural colorants are plentiful. By using all natural ingredients you know that your soap doesn’t contain weird chemicals and toxins. You can assure others who use or buy your soap that it is natural and most people will really appreciate that. Natural colorants also vary greatly in color so you will always have a unique and rustic look. Another benefit is that it doesn’t take a whole lot to get some color and for a natural look, you can just use a little bit.

Natural Colorant Challenges

The hardest thing about natural colorants is getting the color right. During the process the colors are highly likely to change. For instance the first time I made lavender soap, I was disappointed that the beautiful purple buds turned green-brown when mixed into the melted soap base. There will be some trial and error during your process. Another challenge is price: natural colorants can be expensive, especially if organic.
