Oral Care Silica

For manufacturers who compound and fill their own paste. We screen cleaning-type, structure-type and high-purity fine-powder silica routes to help balance cleaning, viscosity, appearance, extrudability and long-term stability.

In short: Sensilchem supplies functional silica for oral care silica — toothpaste, oral-care pastes, oem / private-label filling. The CENSIL grades quoted on this track are CENSIL 310, CENSIL 320, CENSIL 150. Decide first whether the customer wants to improve cleaning, paste structure or long-term stability, then choose the silica route and set up a formulation trial. Specifications are issued per enquiry, and the fit is confirmed on your own line.

What does silica do in oral care silica?

  • Set up a joint test path across cleaning performance, paste structure and consumer feel.
  • Reduce syneresis, phase separation and appearance instability by comparing materials of different surface area, purity and pore structure.
  • Start from a single small-sample validation and expand to multi-SKU paste projects.

Who is this track for?

  • Toothpaste plants with formulation, compounding and filling capability.
  • Local brand manufacturers, OEM / ODM and private-label filling operations.
  • Oral-care customers developing multiple SKUs who are willing to run material screening.

Which CENSIL grades are used for oral care silica?

Candidate routes across different surface areas, purities and pore structures. Oral care is a formulation-led track — selection is confirmed by RDA, viscosity and stability testing on your own paste, not by a datasheet.

We publish the selection logic, not the numbers. Data sheets are issued per enquiry so the figures match the current supplier revision and your application.

CENSIL 310

A moderate-surface porous route for food powders, brewing stabilisation, toothpaste and flavour carriers. The general-purpose choice when structure matters more than sheer capacity.

CENSIL 320

The high-surface porous grade. Used in food and oral-care work where adsorption and structure both matter, and it is our preferred base material for fluoride-removal functionalisation screening — as a candidate substrate, not a finished adsorbent.

CENSIL 150

A fine-powder candidate for oral-care paste structure and appearance work. Selection here is settled on your own paste — cleaning behaviour, viscosity and storage stability — rather than on a datasheet.

How do you test a silica for oral care silica?

Test dimensionWhat to watchWhat it tells you
Cleaning / abrasionWhether it meets the product positioningTells you if the cleaning route fits
Paste structureViscosity, thixotropy and extrusion behaviourTells you filling and use experience
Appearance and feelFineness, uniformity and mouthfeelTells you the consumer experience
Storage stabilitySyneresis, separation or structural collapseTells you the scale-up risk

Which reference brands do customers benchmark against?

Customers commonly benchmark against Evonik ZEODENT® (113, 165), PQ Corporation dental / toothpaste silica series, and Solvay specialty oral-care silica.

Trademarks belong to their respective owners and are named for orientation only. No equivalence is claimed; fit is confirmed by your own trial.

Which grade should you start with?

Decide first whether the customer wants to improve cleaning, paste structure or long-term stability, then choose the silica route and set up a formulation trial.
