Bubble Bath bar How much Kaolin Clay

[Kristin2011]

I have tried to search for this answer on google several times and I always keep coming up empty handed. I am hoping someone here would know how much Kaolin Clay I can use to make the bubble bars more stable? This is a basic recipe I found online but I always like to add ingredients to it to make it unique. Any suggestions?


Dry Ingredients:
1cup Cream of Tartar
1 cup Baking Soda
½ cup of SLSA

I also want to add Aloe Vera Gel

I saw this recipe somewhere. I can't remember where I found it, but I have it written down. I haven't tried it, though.
1-Cup Baking Soda
1-Cup Sodium Lauryl Sulfoacetate (SLSA)
1/4-Cup White Kaolin Clay
1/4-Cup Cream of Tartar


And as for adding aloe, I'd add a preservative to your recipe then.
