Issue 15/2019 - New specialty silica reshapes dental health

Evonik has launched a new specialty synthetic amorphous silica SPHERILEX^®148 that not only cleans teeth, but also restores their health
.

Evonik's SPHERILEX^® production technology is a revolutionary patented production process that enables materials with a unique spherical structure, a very narrow particle size distribution and uniform porosity
.
Thanks to unique production process advantages, approximately 40% of the particles in SPHERILEX^®148 are smaller than dentin tubules
.
Compared with traditional non-spherical precipitated silica, it has a high affinity, which can effectively block dentin tubules, block the invasion of hot and cold liquids, and play a role
in alleviating tooth sensitivity.
The carefully polished spherical particle shape gives it a unique smooth taste when brushing, and can reside in the dentin tubules after brushing, providing long-lasting protection
for dentin.
SPHERILEX^®148 achieves a high level of cleaning performance at low dosages, fully removes tartar from the tooth surface, and reduces damage to stains and plaque
.
In addition, it has a lower degree of wear on the enamel surface, which can help the toothpaste strike the perfect balance
between cleaning power and damage to the teeth.

In addition to SPHERILEX^®148, Evonik's silica products in other sizes are also very
effective.
For example, SPHERILEX^®145 for whitening toothpaste formulations containing phosphate can provide a high cleaning effect at 15%~20% of the added amount; The moderate level of wear on teeth reduces wear
on materials such as enamel, metal and plastic.
