These oatmeal bath bombs can help soothe dry skin and eczema. Ground oats, shea butter and essential oil create a nourishing and relaxing bath experience.
This post, to be honest, should have been finished quite a few weeks ago. Right around early spring after all those long winter months when your skin is at it's ashy itchy height. Needless to say that this time we're in right now has thrown things off around here quite a bit. Turns out having three kids at home 24/7 is no joke 😉
But, hey, is there ever a wrong time for soothing, nourishing, wonderfully relaxing bath bombs? Not in my books 🙂
The ingredients for these oatmeal bath bombs were specifically chosen for their ability to soothe dry skin conditions like eczema and psoriasis. They have the same skin benefits as a traditional oatmeal bath only a little bit fancier 😉 Bath bombs are a great way to add a little pezas to your bath time and kids love them.
How to Make Oatmeal Bath Bombs with Shea Butter
Making bath bombs is a lot like baking: you measure, you sift, you combine the wet and dry ingredients separately and at the end kneed them into a “dough“.
The consistency of that „dough“ or mixture is key though if you want to get that perfectly round and smooth bath bomb. It needs to be wet enough to hold it’s shape when squeezed together, but not too wet or else it will form unsightly bumps.
Another thing that can sometimes be tricky especially with round bath bombs is the drying process since they tend to loose their nice ball shape. Oftentimes the bottom flattens. To prevent this I like to dry bath bombs in two phases: first removing one half of the mold and giving time to dry and then the other.
If you want to know more about bath bomb making, Q & A and troubleshooting I’ve written an entire blog post about it.
This oatmeal bath bomb recipe is pretty straight forward however and easy enough even for beginners.
Key Ingredients used in these Oatmeal Bath Bombs
Baking Soda and Citric Acid
These two ingredients make up the bulk of the bath bomb mixture. When mixed together baking soda and citric acid will set off a fizzing reaction when immersed in water.
Ground Oats are very nourishing and moisturizing for the skin. They're well known for their ability to soothe itchy skin and inflammation thanks to a substance called avenanthramides that is solely found in oats. They can also gently cleanse the skin due to small amounts of saponins.
Colloidal oatmeal is a term used to describe whole oats (including the bran) that have been very finely ground and sifted to ensure a very fine particle size. Which is very important if used to make lotions or creams.
For our purposes we will simply grind the oats in a coffee grinder or food processor. Since they will dissolve in the bath water I’m not concerned about the particle size being a little less fine.
Shea butter has many wonderful skin benefits. Full of moisturizing fats and skin loving vitamins. It's a relatively soft butter that absorbs into the skin at a slow speed. This makes it especially valuable for irritated skin since it will create a protective barrier on the skin for a long time. All the while nourishing and healing the skin.
Shea butter has anti inflammatory and antibacterial properties. And has shown to be effective to reduce redness and irritation associated with eczema.
Chamomile and Lavender Essential Oils
Roman chamomile essential oil has anti-inflammatory and antibacterial properties that promote healthy, smooth skin and can ease irritation and itchiness . It has been used as a natural remedy for eczema, wounds, burns and skin irritations.
Lavender essential oil has similar properties as chamomile essential oil: it can help soothe eczema and other dry skin conditions, it's anti-inflammatory and can promote skin healing. These two oils together form a dream team when it comes to soothing itchy skin.
Polysorbate 80 is an emulsifier and solubilizer it helps disperse oil more evenly in the bath water instead of pooling on top. It also prevents micas and other colorants from clinging to the side of the tub and leaving a ring around your bath tub. Polysorbate 80 is considered safe and is often used in food items, if you wish to use a natural alternative you could try liquid sunflower lecithin (some folks report similar results with it).

These are gorgeous, and they look so soothing!
😊 yes they smell lovely 😊
Beautiful, Celine! I love how you decorated the dried cornflower and chamomile!
Awww, thank you!
Hi, thank-you for this recipe. I just wanted to check do I just use 1 teaspoon of Polysorbate 80?
Hi Rachel, I used 1 tsp and that was enough for me. You can use up to 1 Tablespoon.
Thank-you, it seemed so little but I am new to this so I don't understand the ingredients yet, although you do explain things so well. I'm sure I will gave fun playing.
Hi, What role does the clay play? Do you use it in all of your bath bomb recipes?
It helps harden the bath bomb, alternatively you could use cornstarch or cream of tartar. I use it in a lot of my bath bombs since it has skin benefits as well.
Happy New year!!
Thanks for another amazing recipe....
Do you have any idea about the usage rate of sunflower lecithin?
Hi Seetha, you’re welcome 💕 I’ve never personally worked with it, but I’ve read that people use the same amount as oils/ butter used in a recipe for example, 1 Tbsp of oil = 1 Tbsp of sunflower lecithin. I hope that helps.
I will also do my research before trying.
