    Abstract: A method of measuring the relative rates of release of a target metal ion from two or more samples includes: (i) providing at least two aliquots of a solution including an indicator, the indicator having a color; (ii) dispersing a sample into each aliquot; and (iii) during step (ii), monitoring the color of the indicator in situ to determine the rates of release of the target metal ions from the samples relative to one another. Each sample includes at least one source of the target metal ion. The indicator contains zincon. The samples are oral care compositions selected from a toothpaste, a tooth gel, and a tooth powder. The target metal ion is selected from the stannous and zinc (II).

    Abstract: A method of detecting stannous ions that includes providing a zincon-containing indicator having a colour, contacting the indicator with a sample, and detecting any resulting change in the colour of the indicator, wherein a change in the colour of the indicator from the colour to colourless indicates that stannous ions are present in the sample. The method is useful for the analysis of oral care compositions. Also provided is the use of zinc on as an indicator for detecting stannous ions.

    Abstract: Oral care compositions containing a stannous salt and sodium tripolyphosphate are provided where stannous tripolyphosphate ionic intermediates comprise less than about 1% of the compositions. Tetrasodium pyrophosphate, a methylvinyl ether-maleic anhydride copolymer and/or a silica oral polishing agent may be added for further efficacy. In a single phase blend, the oral care composition may be effectively limited to comprise less than about 10% water. In a dual-phase blend, a mixture having the stannous salt in a first phase and the sodium tripolyphosphate in a second phase may be generated from a dual chamber storage tube (with each phase provided from a separate chamber) immediately prior to dental care usage.
