Native and porous starch as white pigment in toothpaste

A method of formulating a dental health product composition having reduced or no titanium dioxide, the method comprising:

• incorporating a starch selected from a native starch, a porous starch or a mixture thereof into the formulation of the composition, wherein the starch is incorporated to partially and/or totally replace the titanium dioxide required as white pigment in the formulation, wherein:
• the native starch is an ungelatinized granular starch produced through a process involving no enzymatic or chemical processing steps, and wherein the native starch has a particle diameter comprised between 0.5 μm and 200 μm;
• the porous starch is a granular starch produced through a process comprising a step of enzymatic hydrolysis of native starch granules with one or multiple amylolytic enzymes at a temperature inferior to the gelatinization temperature of the starch, and wherein the porous starch has a particle diameter comprised between 0.5 μm and 200 μm and has multiple pores on the surface with diameter comprised between 0.01 μm and 5 μm.
