Abstract
An oral care product including an oral care rheological solid composition including a crystallizing agent, an aqueous phase, and oral care adjunct ingredient. The oral care product can be a floss, a dentifrice, and/or a whitening product. A method for making an oral care rheological solid composition by providing water, providing crystallizing agent, providing NaCl in an amount of about 10% or less, by weight of the oral care rheological solid composition; and mixing the water, crystallizing agent, and NaCl to produce the oral care rheological solid composition.
Core Innovation
The invention relates to an oral care product comprising an oral care rheological solid composition with a crystalline mesh of interlocking, fiber-like crystalline particles. The crystalline mesh is formed from a crystallizing agent present at about 0.5% to about 7% by weight of the oral care rheological solid composition, and the mesh defines voids that contain an aqueous phase, where the aqueous phase comprises greater than about 80% by weight of water.
In the described compositions, the crystalline mesh is self-supporting and expresses entrapped aqueous phase when compressed. The aqueous phase can optionally include oral care actives, and the document characterizes the compositions by firmness, thermal stability, and aqueous phase expression.
The invention further emphasizes formulation design elements affecting crystalline mesh formation and performance, including narrow chain-length distributions of sodium fatty-acid crystallizing agents that form fibrous crystals at very low crystallizing-agent levels. Sodium chloride is discussed as raising thermal stability, and the compositions can include oral care adjunct ingredients such as fluoride/tin and metal ions, and optionally peroxides/whitening.
Claims Coverage
The document includes two independent claims. Across these claims, the main inventive features focus on an oral care rheological solid composition defined by a crystalline mesh of interlocking fiber-like crystals with voids containing a predominantly water aqueous phase, a specified polysaccharide suspension agent, and functional behavior in unbroken and broken states.
Crystalline mesh holding a water-dominant aqueous phase in voids
An oral care product comprising an oral care rheological solid composition wherein a crystalline mesh of interlocking, fiber-like crystalline particles is formed from a crystallizing agent present at about 0.5% to about 7% by weight, the crystalline mesh defines voids, and an aqueous phase comprises greater than about 80% by weight of water and is contained in the voids.
Specified polysaccharide suspension agent in a defined weight range
An oral care product of the crystalline mesh composition further including from greater than 0% to less than about 2% by weight of the oral care rheological solid composition of a suspension agent comprising polysaccharide.
Oral care adjunct ingredient in the aqueous-phase void system
An oral care product of the crystalline mesh composition comprising an oral care adjunct ingredient together with an aqueous phase comprising greater than about 80% by weight of water contained in the voids of the crystalline mesh.
Unbroken and broken state with expressed aqueous phase
An oral care rheological solid composition having a first, unbroken state and a second, broken state wherein the aqueous phase is contained in the voids of the crystalline mesh in the first, unbroken state and, in the second, broken state, the crystalline mesh is broken and at least a portion of the aqueous phase is expressed out of the oral care rheological solid composition.
Overall, the independent claims define a predominantly water-containing oral care rheological solid composition structured by a self-supporting crystalline mesh that defines voids, uses a crystallizing agent at about 0.5% to about 7% by weight, includes a polysaccharide suspension agent at greater than 0% to less than about 2% by weight, and includes an oral care adjunct ingredient. The second independent claim further requires functional switch behavior between an unbroken state where water is contained in voids and a broken state where the mesh breaks and expresses at least a portion of the aqueous phase.
