摘要：
Processes for preparing an oral care composition having improved taste, color, odor and/or clarity, wherein said processes comprise the steps of: providing an unfiltered dentifrice component selected from unfiltered alkyl phosphate surfactants, alkyl phosphate ethoxylated surfactants, lauryl sulfate surfactants, betaine surfactants, antibacterial agents, cetyl pyridinium chloride, metal Salts, phytic acids, or mixtures thereof filtering the unfiltered dentifrice component with an adsorbent to form a filtered dentifrice component and incorporating the filtered dentifrice component into the oral care composition. In one such process, activated carbon with a median particle size of less than or equal to about 30 μm, optionally a macro-mesoporous:microporous ratio about 0.9 or higher and optionally a BET per Total Volume of equal to or less than about 1600 m^2/g, has been found to remove undesirable contaminants from oral care dentifrice components, such as alkyl phosphate surfactant, alkyl phosphate ethoxylated surfactant, lauryl sulfate surfactant, betaine surfactants, antibacterial agents, cetyl pyridinium chloride, metal salts, or phytic acid.
