Spirulina in Soap Failure

[Rholeen]

Hi All, I am searching how to give a touch of subtle green in my soaps ( with minimum luck). I have tried spirulina but it kept going brown! even at 1/4 tsp per 1000 gms of oils. I have read some use sage and others spinach. So please advise if you have used have you used fresh, dried or frozen. If so how much per 1000 gms please. Thankyou

Almost all of the plants are going to turn brown in soap due to the high alkalinity.

Have you tried French green clay? It makes a nice soft green, and adds a nice slip to the bars, too.

Thanx, no not yet, I think I will need to

I’ve used spirulina to color soap in the past, but it’s been a minute and I can’t recall the details. I get lovely green shades when I use Matcha green tea powder and have the best luck when I use oil that has been infused with color from the tea powder as opposed to adding the powder directly. See for example this post where I made a coconut oil infusion using tea powder. I’ve also used liquid oils for infusions with good results. This longer thread has a lot of discussion and examples.

Matcha! Yes, that’s what I was trying to recall last night, but couldn’t remember the word. My mind was stuck on, “It’s not green tea - but it is a tea that’s green.”
