Great in theory, but ...

The manufacturing process for making concrete colourants can be significantly different from the process used to make the same ingredient for cosmetic use.

Even if the ingredient is made in exactly the same way (using exactly the same metals and chemicals), there may be flow additives (or other additives) that would make the concrete colour unsafe for use on skin.

It could be as simple as it is just not purified to the same extent as a cosmetic ingredient, and there are residual chemicals and/or metals that are at acceptable levels for inclusion in concrete, but not for putting on skin.

So, I would advise to use only use cosmetic or higher grade ingredients.

Your big box hardware store might have "Spanish Red". It is iron oxide for giving a red color to concrete.

I appreciate the time everyone put in to this. I will check K&W or wait on Canwax. The Rose clay idea is good but think I'll just have to exercise some patience.

You can heat infuse paprika into a light colored liquid oil, and substitute the colored oil for the non-colored oil. Use enough, and you are going to get that iron oxide color.

That's very interesting. How much is enough? And how much infused oil has to replace the non-coloured oil? I have only ever gotten orange out of paprika. Oh, just remembered, the red oxide was only to colour a portion of a 3 colour swirl so guess that wouldn't work.

You can still do it it just takes a bit of maths.

Add math to this stressful batch of soap and it will push me over.

Red 40 is water soluble pigment not good for soap, we have many Canadian Supplies, you are in Ontario; Xen, Candora, Saffire Blue which I do not recommend then NDA in Mississauga, there is a few more
Are you close to me, I have a lot of soap colorants, could share

Xen is quite expensive, NDA doesn't carry oxides, not fond of Saffire Blue, Candora is good! Kind offer of you! PM me.

Reaching here - but it might be worth experimenting with all-natural crayons, if you can find them.
