FIELD: chemistry.
SUBSTANCE: proposed oral care composition includes: a) one or more pyrophosphates, wherein the total concentration of pyrophosphates in the composition is from 0.9 wt % up to 1.1 wt % in terms of the composition weight; b) one or more thickening gums, wherein the total concentration of thickening gums in the composition is from 1.25 wt % to 1.6 wt % in terms of the composition weight; and c) a source of zinc ions, which is a mixture of zinc oxide and zinc citrate, the ratio of the amount of pyrophosphate to the amount of thickening gums is less than 0.8. It is also proposed to use a combination of one or more pyrophosphates with one or more thickening gums to reduce or prevent the phase separation in the oral care composition under subclauses 1-15.
EFFECT: use of the above pyrophosphate combination with thickening gums provides improved stability of the composition with respect to phase separation while maintaining an acceptable taste and mouth feel when using a composition containing a source of zinc ions.
