    Abstract: A tooth whitening oral care composition is made by combining ingredients comprising flakes of a water soluble whitening film, a dye with a hue angle in the CIELAB system ranging from 200 to 320 degrees, and an orally acceptable carrier vehicle. The flakes of the water soluble whitening film comprise: (a) a film-forming polymer comprising hydroxyalkyl cellulose wherein the hydroxyalkyl cellulose has a viscosity of about 1 to about 1000 millipascal seconds (mPa.s) as determined as a 2% by weight aqueous solution of the film-forming polymer at 20 C using a Ubbelohde tube viscometer; and (b) a pigment with a hue angle in the CIELAB system ranging from 200 to 320 degrees.
