This bath bomb smells so divine! Toasted coconut with lime! And, the coconut milk gives it extra, extra, extra, foaming ability. You can tweak the lime essential oil and the witch hazel depending on whether you’d like a stronger lime scent – just keep the total to 2 ounces. I found ½ ounce of lime essential oil just enough to allow the coconut scent to come through, too. You get the coconut scent from the flour and milk. Lime in the coconut bath bomb recipe will be one of your favorites!
A LITTLE ABOUT THE INGREDIENTS
If you can’t find coconut flour and powdered coconut milk at your local grocery store or Walmart, try a health food store, or Amazon. Don’t substitute regular flour or regular powdered milk in this recipe. The result won’t be the same.
Coconut oil and fractionated coconut oil are two different things. Coconut oil comes in a jar – it’s solid and white. It resembles lard. Fractionated coconut oil is liquid at room temperature, is clear, and comes in a bottle. You’ll almost definitely be able to find both in your local grocery store or Walmart. I use LouAna brand.
Lime in the Coconut Bath Bomb
3 cups of baking soda
1 ½ cups of citric acid
1 cup corn starch
1 cup powdered coconut milk
½ cup coconut flour
2 ounces coconut oil
1 ½ ounces fractionated coconut oil
1 ½ ounce witch hazel
½ ounce lime essential oil
6 mL polysorbate 80
Zest of two limes – let dry a few hours or overnight
Measure all dry ingredients EXCEPT citric acid in a large mixing bowl – I use the bowl of a stand mixer. Place a tea towel over the stand mixer, and at a speed of 1 or 2, mix with whisk attachment until thoroughly combined.
Next, measure the coconut oil and fractionated coconut oil in a microwave safe dish, using a digital kitchen scale. Melt in the microwave on bursts of 10-15 seconds, stirring between each burst. Coconut oil melts fast, so don’t be tempted to go for longer than 15 seconds at a time.
Measure lime essential oil, P80, and witch hazel in a separate container. Once the coconut oil has cooled slightly, combine the essential oil mixture with the coconut oils. Stir.
With the paddle attachment, on a speed of 1, slowly, but steadily, pour the coconut oil mixture into the dry mix. Increase the speed to 2. Continue mixing until thoroughly combined.
Once combined, add citric acid, ½ cup at a time. If the mixture begins to react, increase the speed of the mixer until the reaction stops.
Continue mixing until the consistency clumps together like wet sand. It will start sticking to the sides of the bowl. Take a handful, squeeze together, and drop it in the bowl to see if it holds together.
Lime zest can either be placed directly in the mixture for specks of green throughout or for decoration as seen in the photo. I tried both ways. I thought that it looked like mold when it was put right in the mixture, so I chose to use it as decoration by placing a pinch on one side of my stainless steel mold. Scoop mixture into each half of the molds, overfilling both sides and then squeezing together.
Rub away excess. Don’t twist the mold. If the bath bomb doesn’t immediately release, tap on each side with a butter knife until it does.
The number of bombs depends on the size of the mold used.
P80 helps to disperse the butter and oils so they don’t stick to the tub, but please always use caution when entering and exiting so you don’t slip.
