Disclosed is a method of manufacturing a multilayer zirconia block for artificial teeth, including a first material mixing step of mixing a 3 mol % yttrium oxide-tetragonal zirconia polycrystal and an organic binder, a second material mixing step of mixing a 3 mol % yttrium oxide-tetragonal zirconia polycrystal, a 5 mol % yttrium oxide-tetragonal zirconia polycrystal and an organic binder, a third material mixing step of mixing a 5 mol % yttrium oxide-tetragonal zirconia polycrystal and an organic binder, a compression molding step of sequentially placing the mixtures obtained in the first material mixing step, the second material mixing step, and the third material mixing step in a mold for compression molding and performing compression molding, and a calcination step of calcining a compression molded product obtained in the compression molding step. This method provides a multilayer zirconia block that contains yttrium oxide, the amount of which is adjusted in the manufacturing process, thus showing a color similar to that of natural teeth after impregnation with a coloring solution.

The present disclosure relates to anhydrous foaming cleanser compositions, which generally include: a) one or more foaming surfactants selected from the group consisting of sodium lauroyl glutamate and diethylhexyl sodium sulfosuccinate, wherein the total amount of foaming surfactant is at least about 8% by weight of the total weight composition; b) a first and a second polyol; c) from about 28% to about 50% by weight of a third polyol selected from the group consisted of PEG-4, PEG-6, PEG-8, and mixture thereof; d) a thickener agent selected from the group consisting of polyacrylate crosspolymer-1, polyacrylate crosspolymer-6, polyacrylate crosspolymer-9, polyacrylate crosspolymer-11, and the mixtures thereof.
