Abstract:
1. A dental bleaching composition for use in bleaching a person's teeth having improved adhesiveness and reduced stringiness, comprising: a peroxide dental bleaching agent included in amount so as to provide a minimum of about 5% by weight hydrogen peroxide; a tissue adhesion agent, said tissue adhesion agent comprising at least one of: a rheology-modifying agent comprising a finely divided inorganic particulate that is stable in the presence of the dental bleaching agent and included in an amount in a range of about 1% to about 8.5% so as to increase long-term rheological stability over time compared to a composition comprising the tissue adhesion agent in the presence of the peroxide dental bleaching agent and in the absence of the rheology-modifying agent; and an aqueous liquid carrier that includes water and polyol into which the dental bleaching agent, tissue adhesion agent, and rheology-modifying agent are dispersed, wherein the tissue adhesion agent, the polyol, and the rheology-modifying agent have a combined concentration that exceeds the concentration of the water so that the dental bleaching composition has long-term rheological stability and retains the consistency of a sticky and adhesive gel for a period of at least 3 months.
