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)

POWDER PHASE

35% baking soda

35% SLSa (powder)

10% cream of tartar

LIQUID PHASE

10% LSB or cocamidopropyl betaine

5% glycerin

3.5% glycol distearate

COOL DOWN PHASE

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.
