    Abstract: An oral care composition, including a structurant including a carboxypolymethylene polymer, a humectant including glycerin, a whitening agent including hydrogen peroxide, and a carrier including water, wherein the oral care composition has a pH from about 4 to about 6, a transmission rate of at least 58%, a refraction index of about 1.40 or less, and a transmission loss rate of 2% or less at a surface interface due to refraction of light, for light in the wavelength of about 400 nm to about 420 nm.

    Abstract: A method of determining a color value of a target object is provided. The method includes capturing an image having a color calibration object and a color reference object. Computed calibration color values for the color calibration object and a first computed reference color value for the color reference object may be determined based on the single first image. A color calibration coefficient may be determined. A corrected reference color value may be determined based on the color calibration coefficient and the first computed reference color value. A second image may be captured. A second computed reference color value of the color reference object and a computed object color value of the target object may be determined based on the second image. A corrected object color value may be determined based on the corrected reference color value, the second computed reference color value, and the computed object color value.

    Abstract: Apparatuses and methods for producing improved photographs suitable for measuring teeth whiteness with a handheld camera using a camera jig are provided. The camera jig includes a base that contacts a surface. The camera jig also includes a light shield made from a tubular structure defining an interior cavity. The camera jig further includes a slot in the tubular structure that supports the handheld camera at a predetermined distance from a target, which may be teeth of a user. The slot aligns a lens of the handheld camera with the target. Further, the light shield blocks substantially all ambient light, other than light of a light source of the handheld camera, from the target as it is photographed.
