Fun with Bubble Bars

What I have learned so far

I 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 try

Keeping 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.

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.

Here are my videos of the making of these bubble bars/solid bubble bath recipes.

How did the bubble bar fair.  Well not very well in my opinion.  The first bubble bars had bubbles that lasted only about 15-20 min.  Also my bubble bars from the Soap Queen's recipe fell flat on me.  I guess I messed with the recipe too much. I should have known really that a bubble bath without a foam stabilizer wasn't going to have long lasting bubbles.  Even the second recipe that I used that has a foam stabilizer the bubbles only lasted about 30-40 min.   But there wasn't as much of them.  It is an ok amount of time but if they where to last an hour that would be better.  And I would like more bubbles.  The recipe that has the foam stabilizer in it was the most difficult recipe to work with but the bubbles lasted the longest.  So I think that I may take the basic bubble bar recipe that Bonnie has and alter it to add some foam stabilizer.  Her recipe was my favorite because it was easy to work with, had lots of bubbles, and the bubbles lasted almost 30 min.  I'll have to get some more supplies since this experiment on which recipe is the best, kind of cleaned me out. LOL  More surfactants

  1. There are tradeoffs between density & persistence of foam. If you look at my page at , you can see that I've done a lot of work on that. Some foam stabilizers increase the volume of the foam at the expense of its density--the individual bubbles in it get bigger--and their effect on persistence is variable, depending on how you test it. If you like to play with the foam (guaranteed if you're a kid, and kids probably get much more frequent bubble baths than adults), a dry, large-bubble foam breaks quickly; but just left to settle undisturbed, those foams can last a long time. Wet, small-bubble foams stand up best to play, but are not as voluminous.

    If you're making a tablet bubble bath, unfortunately most of the surfactants that stabilize foam come most conveniently as water solutions, not dry powders, so it's hard to incorporate a large amount of them. The alkanolamides such as lauramide DEA are potent foam stabilizers that are available as solids, but they're relatively irritating to skin & eyes, even though they've had a lot of use in shampoos, etc. You might instead want to try a non-surfactant bubble booster such as hydroxyethylcellulose, which is edible & also used in bubble blowing solutions, and is available as powder; some think it feels too slimy in use, though.

    I did once make an all-surfactant tablet of disodium lauryl sulfosuccinate powder and a spray-dried cocamidopropyl betaine that I got a sample that came to me as a gummy solid from Henkel, but I don't think the latter is generally available. It worked well if I held it in a cage or sock of some kind under the faucet; I could dissolve as much as I wanted, then remove the remainder.

  2. what was the texture like for bubble bar 3? my bubble bar batch that is resting now has a marshmallow fluff texture to it.

  4. Have you ever baked your bubble bars to dry them? I hear they get really hard and near indistructable!
