The ocean is a fantastic source of inspiration. These Sand Dollar Bath Bombs were inspired by the textures of the seashore and the treasures found there. The Sand Dollar Mold creates the perfect bath bomb size and shape, while Tropical Vacation Fragrance Oil gives the bath fizzies a light beachy scent.
This recipe consists of the bath bomb basics: baking soda (sodium bicarbonate) and citric acid. A touch of Epsom salt gives the bath water additional skin-loving properties, but could be omitted if you prefer. Polysorbate 80 prevents the coconut oil and micas in this recipe from pooling on top of the water and clinging to the side of the tub.
