I’ve had such great success making and selling my handmade solid sugar scrub cubes, that I finally got around to taking a customer suggestion to make them as solid salt scrub cubes. However, if you want to use something other than ordinary table salt, these are a little trickier than the sugar scrub cubes and will crumble if you don’t make the a few recipe adjustments.
Since I was making a few adjustments anyway, I made these salt scrub cubes extra moisturizing so that they feel more like a traditional salt scrub but in solid form. They are perfect for getting your feet ready for sandal season or just giving your body an all over exfoliating and moisturizing treatment. I used Epsom salts for this recipe, however if your budget allows, you can use dead sea salts for all or part of the salt.
4 oz. Refined Shea Butter
2 oz. Cocoa Butter
16 oz. Epsom Salt
2 Tablespoons Jojoba Oil
1 Tablespoon Pink Grapefruit Essential Oil
Pinch of pink cosmetic mica or oxide or ultramarine pigment powder (optional)
You can use a loaf pan to make these or even a square baking pan – whatever you have handy. Simply line your molds with plastic wrap or food service film taping the film at the top of the mold. (Alternately you can use decorative silicone molds for this. These offer so many sizes and options. You can also make these as bars rather than cubes.)
Start by weighing out your melt and pour soap base using a scale, then heat in the microwave or a double boiler until about half melted through. Next, you’ll weigh out your shea and cocoa butters and add them to your soap base. Continue heating to complete the melting process. Once melted, remove from your heat source and stir. Then measure out the jojoba oil and fragrance using a Tablespoon measurement and stir into the melted butter and soap base. In a separate bowl, weigh out the Epsom salts. If using a pigment for color, cut in a pinch of color using a butter knife or spatula. Now pour the Epsom salts into the butter/soap mixture and mix well. Finally, scoop the salt scrub into your mold and level with a spatula, then place in the refrigerator until solidified.
Once your scrub has solidified, gently remove the scrub from the molds by lifting it out of the mold with the plastic wrap from the top edges of the plastic wrap or simply push out of your silicone mold. If you used a loaf mold, you can use a Chef’s knife to cut the solid salt scrub into cubes. Place the salt scrub cubes in an airtight container until use.
To use these salt scrub cubes, simply crush one or two cubes in your wet hands and slather over your body. Rinse, then pat dry.
