Abstract

An oral care composition for whitening the teeth, including a peroxide source comprising a cross-linked PVP-H202 complex, a peroxysulfate whitening agent, a hydrophobic base, and sodium tripolyphosphate.

Description

Background technique [0001] Oral care products with tooth whitening properties use a variety of active ingredients to remove stains or whiten teeth. The most commonly used whitening active ingredients are peroxide sources, such as hydrogen peroxide. These products usually contain a considerable amount of peroxide source, usually up to about 10% hydrogen peroxide. However, at high concentrations, hydrogen peroxide may irritate teeth and gums, and in addition, hydrogen peroxide is an unstable molecule that breaks down easily, especially in aqueous environments. [0002] Therefore, there is a need for oral care compositions that use lower concentrations of peroxide sources and / or alternative oxidizing agents that are stable, provide effective tooth whitening and have good Micro robustness. Contents of the invention [0003] This summary is intended only to introduce a simplified overview of some aspects of one or more implementations of the disclosure. Other areas of applic...
