ECOSIL12 (silicon for whitening):
Chelating agents such as phosphates are usually added to whitening toothpaste formulas to improve cleaning and whitening performance, but this will significantly increase the wear and tear on the teeth. Ecosil-12 is prepared using EXTPURE's characteristic NSE technology, which has a more uniform sphericity. When used with active substances such as phosphates, it can reduce the growth of wear value.
•High sphericity reduces friction and reduces wear on teeth
•High sphericity reduces irritation and tastes milder
•Easier to mix evenly during toothpaste production
ECOSIL04 (anti-sensitivity silicone):
It is recommended to add an anti-sensitivity formula, control the particle size D50 at 3-4.5μm, and half of the spherical particles are smaller than dentinal tubules. It helps to seal the dental tubules and reduce tooth sensitivity, and the spherical particles are more suitable to reside in the dentinal tubules. It is recommended to be used in anti-sensitive toothpaste formulas.
