Liquid dye

There are various liquid dyes you can buy. Not all of them are suitable, make sure you buy soap safe and skin safe liquid colors.

You will only need a few drops, so color your soap drop by drop.

A large benefit of liquid dyes is that they are very easy to work with, no mess.

They will leave the soap translucent unless you use a lot.

Almost all of these liquid dyes will bleed when used in a multi color soap,

so do not use liquid dyes for anything but single color soaps, or make very sure you buy non-bleeding liquid colors and test those by leaving them for a month or two to make sure they really do not bleed.

Most liquid dyes will fade if exposed to too much UV light.

Use liquid dyes if you are looking for matte or translucent colors.



There are various micas you can buy. Not all of them are suitable, make sure you buy soap safe and skin safe mica.

Use mica if you're looking for a shiny/shimmering type of color. Not all mica is shiny but most are at least a bit. If you use mica in a white base the color will be more matte.

Premix your mica with a little alcohol or your scent oil to prevent clumping. Unless you like the look of a few colored clumps, I've made a few soaps like that myself on purpose.

There are cruelty-free micas available, these are generally sold as 'synthetic mica'.

Besides coloring your entire soap with mica, you can also mix some with alcohol and paint your soaps. This will rub off in the packaging and with the first use though, you can carefully 'seal' your painting by painting a layer of clear base over it to prevent this.

You *can* do translucent soap with mica with some practice, but if you're doing a single color soap I would prefer liquid color for that as it's easier and also not shimmery.


Colorblock system

A lot of soap shops carry colorblock systems for soap coloring. These systems may be slightly expensive but they are generally very easy to work with, don't bleed and some are translucent, making these a good substitute for liquid dyes in multicolor soaps.

The stained glass soap on the cover photo was done with Zenicolor colorblock system, plus activated charcoal for the black.
