Bath bomb recipe
Let’s go through an easy bath bomb recipe that seems to be full proof. I have heard some people complain that their recipe breasks apart to easily. This recipe seems to be foolproof for me.
Bath bomb recipe
1 Cup of baking Soda
1/2 Cup Citric Acid
1/2 Cup of Epsom Salt
3 tsp oil This can be any oil of your choice. You probably have canola or olive oil at home.
1 tsp distilled or tap water
Whisk, bowls and molds
Optional additives to our bath bomb recipe
You can weigh your mixing bowl prior to adding the ingredients but this is not necessary. I find it useful if I am adding essential oils as they have a strong scent and are easy to over do.
Coloring -Mica, botanicals or food dye. See below when I go more in depth with coloring.
Essential oil -your choice.
If you have a bath bomb mold this is the best. remember to tightly pack the mixture. If you do not have a bath bomb mold you can use a flexible silicone mold. They are sold on Amazon. I like this one Commercial Strength Silicone Baking Molds FDA Food Safe Dishwasher, Microwave, Freezer Safe (Heart)
If you do not have any type of mold then make a ball as you would when you ate making a meatball. They will not be as neat but the video below gives a good example of what they will look like, just remember to tightly pack it.
Baking soda along with citric acid give the fizz reaction.
Bath bomb recipe method
Stir all the dry ingredients together.
Mix liquid ingredients together. This includes the water and your oil, do not add essential oil at the time.
Slowly add the liquid to the dry ingredients. If you add too much water at one time the bath bomb may not fizz as much later on. Do small amounts at a time then mix or you can use a spray bottle to introduce the water oil mixture.
Lastly of you want to scent you bath bomb now is the time to do it. There are a couple of ways to do this. Either slowly add 1-2 drops at a time to get the scent you like. Remember you need to mix after adding these drops so that the mixture is evenly scented.each. Another option would be to weigh the bowl prior to starting and add no more than 1% of the total weight of the recipe. Try .2% to start off with.
The consistency should be like wet sand.
Color options for our bath bomb recipe
There are many ways to add colors. You could use food dye but look at the ingredients. I mentioned in the video that certain brands have parabens and propylene glycol in them. Propylene glycol is an alcohol that has been associated with skin irritation. It is also on the Environment Canada Domestic Substance List as being expected to be toxic and harmful.
Mica, clays and botanicals can be used for coloring.

Glitter for our bath bomb recipe
I think mica glitter make less of a mess. If you glitter from an arts and crafts kit is is more likely to clog up the drain.
Think out of the box
If you are making bath bombs with children or gifting them to a child, there are a lot of options. Think bath toys! You could use a plastic toy or one of those capsule that expand when placed in water, they will make bath time more enjoyable for a little one.
If you do not want to make bath bombs or need some supplies here are some choices.
About the ingredients in this bath bomb recipe
Baking soda-In its natural form, baking soda is known as nahcolite. Which comes from the natural mineral natron. Baking soda is used in cooking to help baked goods rise. It can also be used to help clean as it is an abrasive. It is considered an odor reducer, this is why people use it in the refrigerator. Baking soda can also be seen in deodorants for the same reason. You may see it in toothpaste, it can help eliminate stains on your teeth. It is important to note that using it too much will injure your teeth’s enamel.
Citric acid is used to preserve foods. It is used in beauty products to adjust the pH. Because it is an acid citric acid it can help slough off dead skin cells and speed new cell turnover. When used in a bath bomb the water in the tub dilutes the acid and its effectiveness but it is great at producing the fizz that people look for.
Baking soda and citric acid react to make carbon dioxide bubbles and fizz
Epsom salt can help soothe the skin. A Uk study found that soaking in epsom salt help reduce joint and muscle aches. Whether or not epsom salt actually helps reduce muscle aches or this is just a placebo effect of the bath remains controversial. This was attributes to the sulfate and magnesium in the salt.
Oils-You can choose different oils depending on what you like just keep in mind that the more oil you use the heavier the bath bomb will be. it will be less likely to float and more likely to break apart.
You may have noticed that I left out cornstarch in our bath bomb recipe. You can add cornstarch up to a half a cup in this recipe but it is not necessary. It is a filler which can help prolong the bath bomb but it will not be as fizzy.
