I have had glacial clay in my stash for a while, but just haven’t gotten around to using it lately. I should be using it more, I wish I had thought to use it in some of the swaps I have done lately. Glacial Marine Clay (INCI: Canadian Colloidal Clay) is an extremely mineral-rich clay that is harvested from the pacific coast of British Columbia, Canada.
It comes as a greenish-grey powder and belongs to the green family of clays. Glacial marine clay can be used in a variety of products including facial masks, mud baths, body wraps, and of course soap. It is gently exfoliating and has a pH factor of 6.5-7.3, very close to neutral.
To use it in soap, I hydrated it in a bit of distilled water first. I used just a little bit of glacial clay in one layer of my soap log, as I couldn't recall how much to use for a gentle exfoliation. This picture of the side of the soap log shows the layer of glacial clay better:
EDITED TO ADD: I forgot to mention that this soap log started to crack in a couple of places on the top after I had poured it, so I used the trick of spritzing the top liberally with rubbing alcohol and then smoothing the cracks with my gloved hands, it worked great!
