Materials for Making Bath Soak with Salt and Powdered Milk

To make a 24-ounce batch of bath soak, you will need a few supplies:

The salts and powdered milk are measured out by weight on a kitchen scale. You will need a pipette for your essential oil, a tablespoon for the dried flowers, and a spoon to mix everything together and fill your jars.

I have used both glass and plastic containers, anything with a tight-fitting lid will work. I like to put my bath soak in cute glass milk jars but I ran out, so this post shows 4-ounce plastic jars.

Ingredients for Making Bath Soak with Salt and Powdered Milk

As you can see, the bath soak is primarily Epsom salt, which is magnesium sulfate. Magnesium is great for promoting relaxation and soothing tired muscles. Himalayan pink salt is added because it is high in minerals and can help reduce skin inflammation. The addition of milk exfoliates and hydrates the skin simultaneously.

I currently use powdered milk from the store in my bath soak, but I am working on a system for dehydrating my own goat milk to use instead. When I get that process perfected, I will make a post showing how I do it!

I have an array of essential oils and phthalate-free fragrance oils for my soap making business that I use for making bath soaks. Some of my favorite essential oils to use are lavender, lemon, and eucalyptus.

I have added dried lavender, rose petals, heather, and calendula to my bath soak for visual appeal. You want to make sure they are in small enough pieces to go down the drain.

How to Use Bath Soak with Salt and Powdered Milk

  • While you are filling your tub with hot water, add the desired amount of bath soak. I usually don’t measure it and just dump some in, but a few tablespoons will do. You can use your hands to help disperse and dissolve the ingredients.
  • Hop in and relax in the tub as long as you can, then rinse your body and the tub out.
