Mica in Cold Process Soap – Part 2

If you haven’t read Part 1 of this post you can find it here

It’s been one week since I made the test bars of soap. It took that long just to be able to un-mould the bars in one piece. You can see from the photo below that the bars were still very soft and the edges smushed on a few of the bars. When using silicon moulds it’s a good idea to have a relatively hard recipe, unless you want to wait about 10 days before un-moulding!

So, the results…


I’m very happy to see that none of the colours I tested have morphed at all. The colours are ‘what you see is what you get’. So when choosing one of our micas you don’t have to worry about the beautiful purple powder turning grey when it mixes with your soap.

A couple of observations I had were

  • The Blue Sky Mica and Ultramarine Blue look very similar. The mica has a little more depth than the UM Blue, but overall they are a pretty close match.
  • The Red Mauve Satin mica, in my opinion, doesn’t look mauve at all. More of a rusty brown colour. I’m seriously thinking of discontinuing this colour and trying to find a nicer mauve.
  • The Patina Gold looks like olive green, not a hint of gold in there!
  • The Chesnut and Luster Brown micas are virtually identical. The Luster is a touch deeper but it’s very hard to tell them apart. These are great micas for mineral make-up though!

So there it is. Keep in mind that none of these test bars had any fragrance added, so if you’re having trouble with discolouration it’s probably a fragrance issue. We try to note on all our fragrances whether they can cause discolouration so be sure to check the descriptions when purchasing your fragrance oils.
