Soap Dye Color Morphing
We’ve been experimenting with our soap colorants lately here at Nature’s Garden, going between our dyes and pigments. We’ve talked about our blue dye and how it can morph your cold process soap, but have you tried our reds or yellows? Well we have! Like with the blue colorants, we used our red and yellow FD&C Da Bomb dyes in cold process and melt and pour soap to show you the differences! As we all know, our pigmented colorants, or FUN Soap colors, will not cause any morphing problems in melt and pour or cold process, and we have conducted this experiment to see if the same is true for our yellow and red FD&C dyes!
Our red FD&C dye was experimented with in both our melt and soaps as well as cold process. In melt and pour, it brought an awesome bright red color as soon as it was added! However, when used in cold process at first we were concerned that it may have the same problems as our blue FD&C dye with color morphing. When I first mixed it into the soap, it was definitely red! However, after I poured it into the mold, it did start to look like an orange color! But after we let the soap sit for the required 24 hours we realized that it was a brick red. So don’t be concerned if you use our red FD&C dye in cold process and it looks orange at first! It does not color morph as badly as the blue! We do recommend using our FUN Soap pigmented colorants over the FD&C dyes for cold process soaps however since the Da Bomb soap dyes can bleed and fade over time.

Cold Process Soap Using Pigments
With our yellow FD&C dye, as you can see in the pictures above, we have tried it out in both melt and pour soap and cold process. It brought a beautiful bright yellow to our melt and pour, and the same goes for our cold process. There was no doubt that it was yellow in cold process! Both of our yellow colorants, FD&C and FUN Soaps, work very well in melt and pour and cold process soap.
The usage of each different kind of colorant for your soaps is based on the pH levels as well as the actual saponification process. Melt and pour soap is technically soap that has already gone through the process of saponification, so it is only slightly alkaline. However, since cold process is made completely from scratch the pH levels are very high initially. Pigmented colors can withstand higher pH levels much better than dyes. The red and yellow soap dyes will not cause major color morphing, but we do recommend using our FUN Soap Colorants for cold process over our FD&C dyes.

Color Morphing in Soap
For any new soap makers out there like myself, do you have specific questions? For example, do you know which kind of soap colorant to use when you are coloring cold process soap? Or have you ever wondered about color morphing in soap? Here at Nature’s Garden, we offer two different kinds of colorants for soap: one being a our FD&C Da Bomb Soap Dyes, and one being our FUN Soap Colorants which are pigments dispersed in vegetable glycerin. The use of each kind of colorant is based on pH levels and the actual saponification process. The saponification process is considered the creation of soap by combining oils/butters and water with lye (which has a high ph). Throughout this process as the soap cures, the pH level (alkalinity) become lower. It is important to understand that pigments tend to withstand higher ph levels better than dyes (especially when dealing with the color blue). In our experiment, we show how blue dye and blue pigment perform in both melt and pour soap (soap that has already been saponified) and cold process soap (soap that is made from scratch and will undergo the saponification process).
In melt and pour soap, because it is technically already soap, it has already gone through the saponification process; so the alkalinity is lower. The dyes, our Da Bomb colorants, do not cause any color morphing problems when used in melt and pour soap. They will color beautifully, as well as our pigments, or FUN Soap Colorants. In the picture below, this light blue colored bundt soap is made with melt and pour soap, as well as our Blue Da Bomb colorant. You can see how nice and pretty this blue coloring is. When melt and pour soap is colored with blue FD&C dye, it will produce a beautiful blue colored soap since the dye never has to encounter a high ph.
However, when different colorants are used in cold process soap, as seen below, the outcome is very different. Because cold process is made completely from scratch, it must undergo the entire saponification process. This means that the pH levels are much higher in cold process soap. In the pictures below, the darker blue soap was made using our pigmented, Ultramarine Blue FUN Soap Colorant. The purple soap, (started as gray and turned to reddish-pink-purple as it sat) was created using our Da Bomb blue dye. (We have used our Shea Butter Cold Process Soap recipe for this part of our experiment). It is evident that blue FD&C dye (our Da Bomb blue dye) will morph in color when exposed to a high ph.
In conclusion: When desiring a nice blue color for your cold process soap, it is wise to use blue pigments instead of blue FD&C dyes. While the blue FD&C dyes work wonderfully in melt and pour soap, they will indeed morph in color when making cold process soap.
