Another beauty DIY for you today, in the form of making your own bubble bath bar.

So, in today’s post, we are looking at making your own bath products again. I have previously shared a tutorial on making your own bath bombs and bath salts and today we are stepping this up a level with making your own bubble bath bar. Perfect for adding a bit of luxury to your bath that not only moisturises your skin but adds a bit of bubble to your bath.

What is a Bubble Bath Bar?

A bubble bath bar is quite similar to that of a bath bomb, except it has a few more ingredients so that it foams and bubbles. Crumble under warm running water to create and release the bubbles into your bath.
Fancy having a go at making your own? Well, let’s get crafting!

How to make a Bubble Bath Bar:

Now, this recipe/tutorial has been adapted from that of Soap Queen’s bubbling bath truffle. Most of the base ingredients are the same, I have just adapted this for the fragrance oil and the colour. I am using a pink champagne fragrance oil and a yellow/gold colour to make this bubble bath bar luxurious.
The other difference is, I use the needle version of SLSA ( Sodium Lauryl Sulfoacetate) rather than the powder form. This ingredient is what makes the bar bubble, and is a surfactant in a lot of bathing products to create a lather. Ideally, you want this in powder form, but the needle version still works.

*Just be careful with using SLSA as it can be an irritant to your respiratory system; so wear a dust mask when using this item*

Also to note, even though these are bars to create bubbles, due to the base of butter, the soap suds do form but will not remain for the whole of your bath. To make the bubbles form more, the water has to be agitated by hand. I am not sure if these will bubble a bit more with the powder version of SLSA.

Ingredients:

To make these lovely luxurious pink champagne bubble bath bars you will need the following items. This is half the quantity of that in the Soap Queen’s tutorial.

• 354g Bicarbonate of Soda
• 99g Citric Acid
• 184g SLSA ( Sodium Lauryl Sulfoacetate
• 35g Cream of Tartar
• 85g Shea Butter
• 63g Cocoa Butter
• 21g Liquid Glycerin
• 7g Polysorbate 80
• 8g Pink Champagne Fragrance Oil
• Yellow Soap Colourant
• Pearl or Silver Mica Powder
• Gold Mica Powder

You will also need:

• x2 large bowls
• Protective gloves (disposable gloves)
• Dust mask
• Weighing scale
• Spatula or spoon
• Measuring jug
• Greaseproof paper
• Sieve

Step 1 – Prepare the dry ingredients:

Start by weighing out your dry ingredients into a large bowl. Add the bicarbonate of soda to the bowl via a sieve. Then, add in the citric acid and cream of tartar. Finally, add in the SLSA, but don’t put this through the sieve. As I said previously, make sure that you are wearing a face mask/dust mask when working with the SLSA. As this is also a beauty product, I would recommend wearing disposable gloves. Then, add in a bit of pearl or silver mica powder to add a bit of shimmer.

Mix the dry ingredients together gently, until they are all fully mixed. Set this aside and move onto the next step

Step 2 – Prepare the wet ingredients.

Now, you want to prepare your wet ingredients. Start by melting the cocoa butter and shea butter together. I did this in the microwave on short bursts between 30-60 seconds long.
Then, it is time to add in your pink champagne fragrance oil, Polysorbate 80, and the liquid glycerin. Mix these together well so that they are fully incorporated.

Step 3 – Add ingredients together:

The next step is to add your wet and dry ingredients together. I would wear your face mask and gloves again for this because now it starts to become a little messy. Gradually add the liquid to the dry ingredients, stirring gently with a spoon or spatula. When you have added all the liquid, go in with your hands to fully mix together. You will feel the bubble bar sticking together, slightly like you are making dough for bread. This is the consistency you are looking for.

Step 4 – Split the mixture and add colourant

To add a swirl in the middle of the bubble bath bar, you need to separate the mixture into two parts. Make sure that one part has slightly more mixture than the other as this will be the outer layer of the bar.

In the largest part of the mixture, add in a bit of yellow soap colourant. Ensure that this is mixed thoroughly and quickly so that the citric acid in the mixture is not activated. Then add in gold mica powder to give it a lovely golden shimmer. This looks lovely when the bubble bar is melted into a bath.

I made the bar this colour as I thought a champagne colour would add to the luxurious feel to the bubble bar, as well as tie in with the fragrance oil being used.

Step 5 – Create the bubble bath bar:

Once you are happy with the colour of your mixture, it is time to form it into the bar. Grab a piece of greaseproof paper and lay this out. Then, place on your yellow/gold coloured mixture into the middle of this. Work the mixture into a rectangular shape, keeping it as even as possible and making sure the mixture is stuck together. If you find it is becoming too sticky, add on a little bicarbonate of soda; just like you would add a bit of extra flour when making bread dough.

Now, add on top of the golden mixture the smaller batch of the pearly shimmer mixture. Try to keep this in the middle area of the golden mixture. Press this in to combine the two together, but so that you still have the two distinct colours.

Then, using the edge of the greaseproof paper begin rolling the bubble bar into a log shape. Similar to how you would make a swiss roll. Keep going until the mixture is rolled up. Smooth out the join line and press the mixture into a log kind of shape.

Step 6 – Cut the bar and allow to dry:

When you have the log shape, it is time to cut down into individual bars. Use a sharp knife to do so, cutting the log into even sections. Then, place the individual bars onto a separate piece of greaseproof paper and allow to dry and harden. I left mine for a few days, turning them regularly in this time to make sure they have fully hardened and dried out before using.

Then, your pink champagne bubble bath bars are ready to use to create a lovely luxurious and pampering bath; or giving away as a gift!

What do you think? I would have liked to see more definition in the swirl but I still think they have turned out fantastic. You will have a slightly different end look to the bars if you have used the powder form of SLSA as this will combine better than the needle form that I used.
