Natural soap colourants – what a beautiful challenge in creating handmade soaps. This post is about earth-sourced colouring options for you, dear soap makers, who wish to keep their recipe as natural as possible.We, at Three Hills Soap, only colour our soaps with plant, fruit or vegetable materials, so our soaps are aesthetically coloured by nature itself. I love to infuse them in various kinds of oils, add them at trace not just for their colour but for their herbal qualities too and I even throw them into the lye – water solution.In natural soap making you have several options for colouring your soap which will include: spices powders (cinnamon, curry, paprika, turmeric, ginger, coffee grounds etc.) and even flowers and plants that could be growing in your garden right now (chamomile, rose, calendula, nettle, lavender, spinach, parsley or alfalfa to mention).I must tell you, herbs, clays, flowers, roots are my personal favourite. Amazing Nature creates for us all types of wonderful colours useful in soap making too. That’s the reason why we don’t use micas or oxides to colour our soap products. Please note that while these cosmetic materials are considered natural they are both created in a laboratory environment. Minerals and micas are found in nature but are often tainted with unsafe heavy metals and are unfit for use (but it is always a matter of opinion and preference).Let’s go to the point…I would like to share with you all a list of some of the natural soap colourants. I have a lot of experience to work with and which I’ve used in our soap collection. As you can see, with a little patience and know-how, you can achieve almost every colour in the rainbow when soap making. Please keep in mind, natural colours used in your soap will always be softer and have more “natural” look than artificial colourants.Oh, I almost forgot to share with you a very important information and that’s the rule of thumb when using plant and flower material in your soap. The rule is that they should be no more than 5% of your total recipe’s weight. If you try using more than that then it’s possible that you’ll have issues with your soap.We must mention that for our natural colourant testing once we poured soap mixture into the mould, we isolated it with a blanket for 24 hours. This really has helped to ensure that each soap went through gel phase, and gelling makes colours look more vibrant.There is also one main disadvantage when it comes to using natural colours and that’s colour fading with time. To prevent that from happening too quickly, we recommend storing your bars in a dry, cool, good-ventilated place and surely out of direct sunlight.We also advise you to work out the best technique for a colourant. If you want a particular natural colour, spend some time on research and experimenting, there’s enough information out there. First, test on a very small batch before going in for final formulation. If you don’t get satisfactory results with one technique, feel free to try another. Adding the colour, whether in oil, water-lye solution or at trace often has a dramatic effect on definitive results.It’s worth a try. Have a look at natural colourant tests below. Aren’t they gorgeous?
