For those of you who are going all-natural and are looking for some colorant options that aren’t dull gray, green or brown, try these! You’ll be surprised how vibrant some natural pigments can be!
Kaolin Clay: More typically used in mineral makeup than as a soap colorant, but I tried it anyway. Very clumpy unless you break it down in a liquid first. Notice it looks slightly pink in the image; that’s because I had a little rose clay left on my spoon! Oops. Titanium dioxide is another great whitening agent.
Rose Clay: Lovely pink in both cold process and melt-and-pour. Needs to be broken down in a liquid first or you will be fishing for clumps. Rose clay is a mild Kaolin Clay.
Safflower Powder: Makes a gorgeous yellow in cold process and melt-and-pour. Another pigment that should be broken down first in liquid because of its clumpy nature. I like the little flecks that are visible in this clear base!
Spirulina: Also known as Kelp and smells very fishy. I add a strong essential oil (like peppermint or lime) to this layer to mask the scent. Needs to be broken down in liquid and tends to leave flecks of pigment. Try pouring your colored melt-and-pour soap through a sifter or strainer to catch lumps of color.
