These are indeed ‘ingredients in the mineral category’, which, according to the standard, must not be in nanoparticular form to be allowed.

These mineral powders, which provide effective protection, have the incommensurable flaw, if they are used as-is in cosmetic formulas, of thickening product consistency and making products unpleasant to use.
