Embodiment 1

[0091] A whitening dentifrice was prepared by mixing the ingredients of Table 1 below. First, prepare the flavor premix by adding BHT to the flavor mixture until the BHT is completely dissolved. In the main container, combine the propylene glycol, glycerin, PEG600 and L1220 Mix to form a homogeneous solution. Then add TSPP, SAPP, MFP, Saccharin and Sucralose to the main container and mix until homogeneous. PVP bound to hydrogen peroxide, fumed silica, and calcium pyrophosphate and PVP were added to the main container and mixed under vacuum to form a homogeneous mixture. The flavor premix and sodium lauryl sulfate were then also added to the main container and mixed under vacuum until a homogeneous mixture was formed.

[0092] FD&C Blue No. 1 lake encapsulated in polylactic acid was purchased from Micro Powders, Inc., Tarrytown, NY. It may be desired or preferred by the consumer to disperse the encapsulated colorant throughout the homogeneous mixture obtained as described ...

Abstract

Disclosed is a stable whitening dentifrice composition including an orally acceptable vehicle including a whitening agent, and a colorant encapsulated by a protective barrier, wherein the protective barrier suppresses migration of the colorant into the orally acceptable vehicle for a duration of time of at least about 1 day. Methods of preparing the whitening dentifrice composition and using the composition to whiten tooth surfaces are also disclosed.

Description

Background technique [0001] Consumer research has found that white is not necessarily the most favorable color for whitening dentifrices such as toothpaste. Research has shown that consumers prefer the aesthetics of blue toothpaste. In addition, consumers feel that blue toothpaste has superior whitening effect compared with white toothpaste. However, dentifrice formulations containing whitening agents such as peroxides are highly reactive with colorants such as dyes or lakes, and therefore formulating blue or other colored dentifrices has proven difficult. Therefore, there remains a need in the art to provide stable, different colored whitening dentifrice compositions, such as toothpaste, to meet consumer demand. Contents of the invention [0002] The present disclosure relates to a stable whitening dentifrice composition comprising: an orally acceptable vehicle comprising a whitening agent, and a colorant encapsulated by a protective barrier, wherein the protective barrie...
