What I have learned so farI have several recipes that I want to try out for making the perfect Bubble Bars. The secret to making easy to crumble bubble bars is in the cream of tartar. If you don't use the tartaric acid (cream of tartar) your bubble bars will be way to hard to crumble. Also Tapioca powder, arrowroot powder and corn starch are some ingredients that seem to have similar characteristics. I believe that they are almost interchangeable in a bubble bar recipe. So if you don't have one but have the other then I would be comfortable substituting one of these ingredients. Keep in mind that Tapioca powder does have a higher thickening power than corn starch or arrow root powder. And Arrowroot powder has a silkier and finer texture than corn starch. Also I've read that Tapioca powder holds onto scent really well. Arrowroot powder does hold scent as well.
Recipes I'm going to tryKeeping all these in mind I'm going to make the SoapQueen's recipe first for bubble bars. However, I want to make them a bit differently only because I already have some different ingredients plus I want to make the recipe more of my own. So I'm substituting the SLSa for another powdered surfactant Bioterge AS90 and I'm also going to substitute part of the cornstarch with arrowroot powder because it disperses in water better than cornstarch and it has a silkier texture. Also I am going to use 'turkey red' sulphured Castor oil instead of regular Castor oil because it is water soluble. Here is the link to Anne-Marie's newest video on how to make solid bubble bath.
The next bubble bar recipe I am going to try is the one I found at Voyageur Soap & Candle Co. website. It has an added ingredient Amphasol CG which is a liquid surfactant that will help to make the surfactants more gentle on the skin. And help to create more bubbles. Only this recipe doesn't contain any cornstarch, tapioca starch or arrowroot powder. I am very tempted to add some arrowroot powder but I think I should try the recipe at least once without it and see how it compares. I think I am going to add a small amount of tapioca starch to hold onto the fragrance better and I am substituting again the surfactant used in the recipe with the one I already have Bioterge AS90. Here is the link to the website where I found this recipe. http://www.voyageursoapandcandle.com/Bubble_Bar_Recipe_s/289.htm
Lastly, but certainly not least If I have enough ingredients left over I am going to make the recipe from Bonnie's youtube video on how to make bubble bars. Again I am substituting the surfactant for my Bioterge AS90 and may substitute some of the cornstarch with arrowroot powder as well. Here is the link to Bonnie's video.
