Making natural soap colorant from red onions

Recently we received a question from one of our newsletter subscribers (sign up with the form just to the right) regarding making a natural soap colorant with red onion skins:

Hello, I tried your recipe for making red dye from red onion skins;
however, the liquid dye smells of onions. Is there something I can add
besides fragrance to eliminate the odor? Thanks for your help.

Here was our response, which we wanted to share with all of you, if you are interested in experimenting with natural soap colorants.

Hi Chris,

Thanks for sending through the question!

You should be really careful just to use the very outer skin from the red onions for the dye, which won’t have much smell – if you take a layer or two of the onion flesh with the skin there is a chance that the dye will smell.

By the time you boil the onions for 15 minutes or so, most of any remaining smell should be boiled out of the liquid for the dye, but once it is added to the lye any remaining onion smell should disappear as well.

Good luck with it, if you have any more questions please send them through to us (see the contact us page in the menu bar at the top).

Many soap makers prefer to use natural soap making colorants for their soaps, as opposed to synthetic ones. However, if the natural colorants don’t work for you, or are too expensive or unpredictable, there are a variety of synthetic colorants that can be used.

This post focusses on synthetic soap colorants, but you can read more about the various soap colorant options in our comprehensive post by clicking here.

Pigments, micas, and FD&C colorants are some of these.

Pigments are colorants that were originally mined, but now, due to FDA regulations, are manufactured in laboratories.

Many natural oxides contain toxic materials, so the FDA chose to approve only synthetic colorants for use in soaps and cosmetics.

The synthetically made pigments have the same molecular structure as the natural ones, but they have a low enough concentration of toxic metals that they are considered “safe” by the FDA. Pigments tend to be pretty stable, and the color that they will impart to your soap is predictable. The liquids are extremely easy to use, but the powders must be mixed with liquid before they are added to the soap batter, and they may clump.

The easiest way to liquefy the colorant powder is to: Continue reading “Synthetic Soap Colorant Options”
