List of Best Colorants for Bath Bombs

One easy way to make bath bombs a lot more exciting and fun is the addition of color. There are various bombs with different colors including speckled bombs, solid-colored bombs and even bombs with distinctly arranged colors. Basically, there is almost no limit to coloring bath bombs. The imagination is a key player when it comes to coloring bath bombs. Usually, bath bomb colorants are of two types: then oil based and the water-based. Therefore, making use of each of these variants usually requires using different methods.

Water-based colorants are usually found in liquid form and are mixed into powdered ingredients with salt or water-based binding agents. Similarly, the Oil-based colorants such as oxides and mica are mixed with powdered ingredients or Oil-based binding agents. Oxides and Mica are the better choices in this case due to the fact that they rarely ever fade or bleed even after a long time period. Also, when dyes are added to bath bombs, the amount of colorant added is drastically reduced for some good reasons.

Some of these reasons include the fact that the presence of too many colorants in bath bombs may cause it to stain the skin. Thereby, making the skin dyed with the color of the bath bomb. Furthermore, it might end up staining the bathtub and the stain could be pretty difficult to get off. In summary, it is not advisable to have a bath bomb with an excess amount of dye. You could also easily make use of naturally colored powders in place of synthesized ones. Addition of herbs and clay could result in an amazing end product.

For bath bomb coloring techniques, we mainly have two names.

  • Mixing Dyes During Liquid Phase

This method of coloring is the most common type of coloring method for bath bombs available. It simply involves the addition of the colorant into the mixture when it is still in the liquid phase. Similarly, you get to decide whether you want to make use of dry powdered colorants or water-based colorants provided that it is water. When you add oxides and mica making use of this method, there is no guarantee of perfect results since the chemicals are not totally water soluble.

Also, the addition of the colorant before including the fragrance oil is advised. This is after you have stirred the borax solution. Also, a dry colorant would require that you get measurements and specifications to the letter to avoid risking any unpleasant uneventualities. Usually, a safe measure of the dry colorant would be about half the size of a teaspoon scooped into the mix.

  • Mixing Dyes During the Dry Phase

This method usually gives the bath bomb a certain freckled or slightly coarse appearance. For this method, you would need to mix the salt with the colorant before including all the other ingredients. Usually, Epsom salt is used thanks to the fact that the rock salts present are larger which therefore effectively increases the ability to better absorb the colorant. All you have to do is scoop the required quantity of Epsom salt and put in a few drops of colorant. Some of the rocks might actually dissolve but that does not constitute a problem.

As long as most of the rocks stay in shape, then you are good to go. In this method, however, there is a likelihood that the colorants would sip into the mixture but the larger amount would be absorbed by the Epsom salts.

Basically there a large number of bath bomb colorants out there but we are concerned with talking about only the best and how to identify the best too. Therefore, here are some of the best bath bomb colorants. We also have a complete buying guide for best natural bath additives that you can add on your bath.
