Celebrate another day of National Bubble Bath Day with a solid bubble bath more suitable for humid climates

Yesterday, we celebrated National Bubble Bath Day with a solid bubble bath formula suitable for a less humid climate. Since where I live can get so humid you can see little water droplets in the air, I modified the formula to avoid using a lot of glycerin, which attracts moisture from the atmosphere to itself. It’s normally a great thing in a lotion or body wash; in a bath bomb or solid product like this, it can set off the fizz far too early!

We still want some glycerin in the mix as it’s a great ingredient for creating big bubbles, but we’ll be reducing it from the 8.5% we used yesterday to 5%.

Instead, I’m using glycol distearate or EZ-Pearl. This lovely, flaky, inexpensive emollient is a pearlizer for our surfactant based products, but also works as a binder for this bubble bath.

SOLID BUBBLE BATH (for more humid climates)


35% baking soda

35% SLSa (powder)

10% cream of tartar


10% LSB or cocamidopropyl betaine

5% glycerin

3.5% glycol distearate


1% fragrance or essential oil

0.5% liquid Germall Plus

Liquid colourant

  1. Weigh the powder phase into a container.
  2. Weigh the liquid phase into a container, then heat until the glycol distearate is melted.
  3. Pour the liquid phase over the powder phase, and mix well with your hands.
  4. Add the cool down phase, mix well with your hands.
  5. Scoop the bubble bath out of the container, and let sit on parchment paper until it is solid.
  6. Package in adorable containers and rejoice!

For this version, I used blood orange & goji fragrance oil (from Windy Point Soap) and didn’t colour it as I wanted to see if it would discolour over time with this FO. It did become a lovely slightly orange-y colour that I quite liked.

As an aside, I know my picture above looks exactly like my shampoo bar, and that’s because I used the same mold for it – the 4 ounce domed Milky Way mold. You can’t really use SCI for this product as it doesn’t flash foam quickly enough for a bubble bath. I have tried it, and although it had some nice bubbles, everyone agreed it could have been better. If you’ve tried it, please share your thoughts about it in the comments below!

    I wonder, if Natrasorb can help with FO?

    • I haven’t found the fragrance fades much in these. I have one that we made in the summer that’s just been sitting in a bowl in the workshop that still smells like vanilla mint.

    Natrasorb works beautifully in bath salts and bath bombs. But I haven’t had much luck with Natrasorb in solid bubble bath. It does not bring enough benefit to be worth the cost. Adding a butter and poly 80 adds more to the party. I do add cornstarch as a hardener when adding butters to solid bubble bath.

    I was looking for a cute gifs to give the kids at my dauther’s birthday party and I think this would be perfect! One question though. I have glycol distearate, but it is in solid flakes and you included it in the liquid phase. Will it desolved or are you refering to a different kind of glycol distearate? I have bought a bag to try thinkening my liquid shampoo but have not had the chance to try it yet. As such, I do not know how it behaves.
    Thanks for your help!

    Sorry for my question below, I should have read the whole post and I would have answered my own question regarding glycol distearate (to my defence, it was late last night when I read it…). Well, with a fresher mind this morning, I could not wait to try the recipe above!!! I used a mix of sodium lauryl sulfoacetate (SLSa) at 25% and disodium lauryl sulfosuccinate at 10% for the powdered surfactant part, but otherwise used the same recipe as above. I scented the batch with pomegranate-mango fragrance oil from NDA and added some red liquid colorant I had on hand. Once all mixed, the recipe felt similar to bath bomb mixture, but less sandy texture. It molded well into small heart-shape ice cube tray. I only try to unmold one so far as they are still soft, but I like the results (see picture). Washing my mixing bowl did create lots of bubbles! And got my daughter quite excited to try them for her bath tonight.
    Thanks for sharing this recipe!

    Is there a certain size you’d recommend not going over, or is it just that bigger means more bubbles? I’m just thinking about bath bombs, and I’ve gotten them in all different sizes, and the big ones almost feel too big for the tub, so I’m wondering if the same concept would apply to the bubble bombs.

    • I like to make smaller solid bubble bath scoops. We did some 4 ounce/125 gram ones, and they felt way too big, so we did some 1 ounce/30 gram ones, and we found 2 worked really nicely in our tub, so I’d suggest trying 2 ounce/60 gram versions.

  • I just have to say I am so excited for you Susan, this site looks great! I’m happy you are able to do this full time now and that so many people are subscribing to help with everything involved in setting up such a great new site, I can tell you have put a lot of work into this. So proud of you and thankful for ALL you do, and I hope this brings you great happiness because you deserve it!

    • Thank you, Julie. You are so kind. I’m so excited about this new space, which may be obvious by how much I’m posting over here. I’m so excited by all the comments I’m seeing and all the sharing that’s going on. I think I’ve had more comments on this blog this weekend than I did in all of November and December on the old blog!
