When it comes to ingredients 'grades', which is best for bath bombs? I would have assumed pharmaceutical grade would be better because of purity, but is it? Is it even safe? I was reading somewhere that some food grade ingredients are better suited as opposed to the cosmetic grade of the same ingredient - and that it just depends on the ingredient.
Has anyone experimented with different grades of ingredients? What have you come to find? Are you allowed to use food grade and pharmaceutical grade ingredients in cosmetics like bath bombs? (if selling for a profit as a part of a business?)
