摘要： Disclosed herein are methods for evaluating the whitening effect of oral care composition on a stained egg comprising staining an eggshell, applying the oral care composition to a portion of the stained eggshell to obtain a treated eggshell area, calculating a ΔE value for the difference in color of the treated eggshell area compared to untreated stained eggshell when calculated in L*a*b color space, wherein the oral care composition comprises at least one high cleaning silica for stain removal. Further disclosed herein are methods for demonstrating the whitening effect of an oral care composition on a stained egg comprising showing an egg that has been stained to at least one consumer and brushing an oral care composition comprising at least one high cleaning silica for stain removal on a portion of the stained eggshell to obtain a treated eggshell area.
