Cleaning Silicas

PCL's precipitated silica cleaning products are considered safe and effective in all dentifrice applications.


PCL offers PURASIL® 200H cleaning silica with outstanding cleaning/whitening. This product is ideal to meet the growing global demand for whitening dentifrice applications. For example,

PCL's high cleaning silica PURASIL® 200H can be used to boost the cleaning of PURASIL® 100L. In this case, the use level of the high cleaning silica is typically 1 to 10 percent.


By replacing a small amount of standard cleaning silica with PURASIL® 300H, a standard formula can be upgraded to a high performing whitening product without a complete reformulation. PURASIL® 300H high cleaning silica can also be used as the primary cleaning silica at five to 20 percent loading levels to deliver the highest level of cleaning performance.

This silica combines soft polishing with little thickening in liquids. It is therefore an excellent ingredient for opaque, transparent and liquid toothpastes of moderate abrasivity.


This silica grade combines hardness with little thickening in liquids. Compared to PURASIL 100L, it provides more abrasivity when applied in opaque, transparent or liquid toothpastes.


As a silica with high hardness and little thickening in liquids, this grade especially benefits by a high transparency in transparent toothpastes.
