I received a gift the other day of some Indigo colouring labelled “Fine Egyptian Indigo – Natural". THANK YOU (you know who you are)!
Wow! Finally maybe I would be able to make my Sea Salt soap blue!
The Indigo colouring doesn’t look natural. It is a vibrant royal blue powder. I will research how “natural” this is. I have also heard that indigo may stain later and the suds turn blue... will try it out when the soaps are ready. In the meantime, I have really enjoyed doing 3 Sea Salt soap experiments.
Sea Salt 1
As I wasn’t sure when to add the indigo, I added it with the sea salt at the end, probably too late as it produced some little blue speckles. But I also got a very nice faint blue. There is a greenish tinge that has not come through in the photo well, which I think may be due to the EO blend being slightly yellow or maybe because of the Olive Oil I am using.
Sea Salt 2
This time, there is no Olive Oil, only clear liquid oils. I added the indigo to the heated oils and stirred well before mixing with the lye solution. When I was bringing it to trace, the mixture was a beautiful sky blue and I was sooooooo disappointed when I added the Eos and it went ugly greeny grey (a colour I know all too well...!). Again the Eos were even more yellow this time. But the soap turned out a nice greeny blue colour. I don't think the green comes out in this photo either.
Sea Salt 3
I did everything the same as for Sea Salt 2 except the EO blend was clearer. Just slightly off clear. Here is the result. I really like this blue. And the scent is really intriguing. Not sure if it reminds me of the sea... but I love it all the same. Can't WAIT to shower with this soap!!
