Make a bath bomb,

Whether it is for you, or as a gift, today I am offering you a tutorial on how to make a bath bomb . I can already hear you telling me about yourself over there: but what is she talking about? What is a bath bomb?

Before any explanation, I remind you of course that it is more ecological to take showers than baths! A bath is between 150 and 200 liters of water ! Whereas, a 5-minute shower (the water is turned off during soaping), oscillates between 60 and 75 liters of water . But we are not perfect entrants ... and we must admit that a little swim from time to time, it can greatly boost morale at half mast, or relieve aches. So if we can have a nice bath with real benefits for our skin, it's even better!

A bath bomb is a bit like a big effervescent pill that you put in your bath before entering it. On contact with water, it effervesces and dissolves quite quickly. You will easily find them on the market in the form of a ball, cube, heart, flower, etc. There are colored, scented, decorated, flowery and sometimes even spangled ones. They are absolutely not used to wash, rather to relax, after a sporting effort, a stressful day ...

Bath bombs can also have beneficial effects on your skin depending on the ingredients they contain (oils, butters, clays…).

A bath bomb, how does it look?

It is the mixture of citric acid (an acid) and sodium bicarbonate (a base) which fizzes on contact with water! The chemical reaction between the acid and the base produces carbon dioxide (pffschh) and a salt: sodium citrate. Depending on the size of the bath bomb, the effervescence lasts 1 to 2 minutes before the bath bomb is completely dissolved.

The basic tutorial:

The basic recipe for a bath bomb is very simple. The two main ingredients are citric acid and baking soda. They are the ones that create the chemical reaction. Then everyone adapts their own recipe, according to their skin type and / or their desires / needs of the moment. To make bath bombs, you will therefore need at least:

50% sodium bicarbonate

25% citric acid

25% clay or starch

A few drops of water

Personally, I particularly like clay, which I prefer to starch. Not only does clay have beautiful cosmetic properties , but it will also be able to serve you as a coloring agent. There are white, green, pink, red, yellow… Have fun!

The additions:


As I told you previously, you can directly use clays for their benefits as well as for their colors in your bath bomb. But you can also use food coloring , and / or vegetable:

spirulina, matcha tea for pretty shades of green;

of turmeric powder or curry for yellow hues / orange,

the powdered charcoal for black, etc ...

Candy :

The oils and vegetable butters are also our friends! And the choice is very wide! Of coconut oil , which will suit all skin types, and which will also provide perfume). Of oil apricot kernel , sweet almond , avocado , hemp, for you to give vent to your creativity!

The softness is found in: the powdered milk , the grated coconut , powdered oats , the cocoa powder ... Once again to you to choose the bath bomb that you like!


Some essential oils may be suitable. It is up to you to find out about the properties of each one. Here too, you will be spoiled for choice, from traditional lavender, including citrus fruits, flowers, etc ... You can even provide an anti-cold bath bomb with a few drops of essential oil of Ravinstara and eucalyptus. But beware, essential oils are very strong, so you have to be careful which essential oils you want to use, and only put a few drops. In addition, essential oils are not recommended for pregnant and breastfeeding women as well as for young children.

You can also use aromas or fragrances (see perfume samples), but be careful, they contain water! And as I explained to you previously, the water will react the bicarbonate and the citric acid !!! The orange peel powder and / or lemon powder can also be used to perfume your bath bombs.


Here too, the key word is: have fun! First with the shapes, depending on the mold you will use for your bath bomb (hearts, circles, flowers ...) You can also embed flower petals (lavender and / or calendula for example), or small sugar decorations (which can melt in the water). You can also camouflage a small gift floating inside (such as a small dinosaur for budding paleontologists), or even a rosebud for the more romantic.

First, mix the powders evenly.

Then add the vegetable oil that you have chosen and in which you have previously diluted your essential oils or flavors with your dyes.

Amalgamate the whole, when you form a ball with your hand, the whole must remain very compact.

Help yourself with a water spray or hydrosol. Sparingly, add a little water at the risk of seeing your mixture swell, and having to start all over.

Put in mold and let harden 24 hours minimum.

Unmold, it's ready! All you have to do is offer or take a good bath.

Remember to keep them away from humidity , at the risk of ending up with unusable dough….
