How To Choose The Best Colorants For Bath Bombs

Skin-friendly

The primary requirement for bath bomb colorants is that they need to be skin-safe. Since you will be sitting in the bath water for some time, it is best to choose a colorant that is clinically-proven to be non-irritating and gentle on the skin. FDA approved colors are the safest ones to choose, especially if you have sensitive skin or if you will be using the bath bombs with babies.

Formula

An important point to consider it is, whether the bath bomb colorant comes in a liquid form or powder. Remember to be exact in your measurements. If you use too much liquid coloring, your bath bombs will be too soft. It could even expand out of the molds. If you use too much of a dry ingredient like clay or mica, then you run the risk of the bath bomb not packing together tightly to take the shape of the mold. If you prefer solid colors, adding the colorant to the liquid is best, and if you are going for a speckled effect, add the color while the mold is still dry.

Non-toxic

The colorant should not contain any toxins or harsh chemicals. Make sure it is free of chemical compounds like parabens and phthalates. Choose natural epoxy resin pigments that are vegan and gentle on the skin.

Non-staining

You do not want your tub to be left looking all rainbow-hued with rings of color after bathtime is done. Therefore choose colorants that are non-staining and leave no traces behind on your clothes, skin, or your bathroom.

Residue-free

You do not want clumps of bath bomb ingredients in your tub, and you want no residues left over as well. So look for streak-free colors that dissolve completely and blend easily. Choose vibrant, water-soluble colors to keep your bathtub residue-free.

These are the 13 best colorants or dyes for your bath bomb recipe. But it is not just buying a color that matters. You must also know how to use it to create the desired shade. Here’s a sneak peek at how to color bath bombs. Scroll down.
