Toothpastes and gels also contain abrasives (such as hydrated silica) to clean teeth; binders (such as xanthan gum, carrageenan or carbopol) to prevent the separation of ingredients; coloring for visual appeal; humectants (such as glycerin or sorbitol) to retain moisture; buffers (such as phosphates) to maintain product stability; flavorings (such as peppermint and cinnamon); and surfactants (such as sodium lauryl sulfate) to produce a foaming action and reduce surface tension.
