Ferric Ferrocyanide

[KimHartley24]

Ferric, how I love thee... let me count the ways: one, two, three, a-four, a-five, a-six...


Haha Has anyone used ferric ferrocyanide in soap? Did you disperse it in the water before lye, after lye, in the oils, in the raw soap after mixing everything together...?

If no one has I'll be sure to record my results FF is so finicky I wouldn't think it'd be a frequently used colorant for soap... but how can you say no to that beautiful Prussian blue...???

I love Prussian Blue. Would love to see a pic when it's done.

Wow - talk about a label turnoff! I'm sure it produces a beautiful color and is harmless, but I might run the other way if I saw something with that name on the ingredient list! It sounds sinister!

The main reason it's not usually seen in CP soap is that it fades.

I don't mean like faded wallpaper, I mean all the lovely pigment GONE and your left with a ugly mottled grey.

Ask me how I know.

i make cosmetics and sell them...but i am an old soapmaker and really loving coming back. FF is one of those ingredients a lot of folks frown on..so if you like to avoid those hot button ingredients...not a good choice. that being said.. i do use it and i love it...but some folks dont

Is this the old blue print photo material? I have seen it used to dye fabric and do a relief using the sun but did not know it could be used in soap. Is there anything that can make the color stick?

 

[AmyW]

I had to go look it up, it doesn't sound as sinister as the name implies lol.

Whole we are on the subject has anyone used gentian violet as a colorant. If so how did it work?

Nope, its not stable in an alkaline product.

My only experience with Gentian Violet is to use it as a wound dressing. It stains and lasts a week or more.

Can think of a couple of people who I'd like to give that soap too :twisted:

 

[KimHartley24]

Yeah so THAT didn't work. (Anyone get the reference? I can't find the clip on YouTube, but here's someone else acting out the same scene for a project: [ame="http://www.youtube.com/watch?v=1fjLs3eVT3I"]http://www.youtube.com/watch?v=1fjLs3eVT3I[/ame])

Best line in the whole movie.

Anyway yeah I tried dispersing it in olive oil, but it didn't really dissolve into it. That was the first problem.... the second is that it basically disappeared into the soap. When I try to use it in making makeup I have to grind the bajeebers out of it in order to get it to be visible, otherwise you can have a 1:1 ratio with white and the white will still be all you see because it HIDES like gaahh... I was hoping the movement of the soap against itself would be enough but nopes. I'll have to grind it into some TD and then use the combination... Dude blue pop is so much easier!

 

[sunnyone]

do you have a magic bullet kim? grind it in that you will get BLUE
