ImerCare PerlWhite 19

ImerCare® PerlWhite 19 For whitening and gentle polishing in toothpastes

  • Stain removal
  • Effective at low concentrations
  • Low dentin and enamel abrasion

ImerCare® PerlWhite 19 is a perlite-based whitening and gentle polishing agent for toothpastes. Toothpaste containing ImerCare® PerlWhite 19 cleans the surface of the teeth without scratching, minimizing damage to enamel, dentin, root surfaces and gum tissue.

Unique morphology

ImerCare® PerlWhite 19 is effective due to its optimized particle size distribution and unique particle shape. Imerys’s innovative, proprietary grinding process enables large particles to be removed and actually modifies particle morphology, transforming 3-dimensional particles into 2-dimensional, platy particles. The combination of the natural hardness of the perlite mineral with this patented technology provides unparalleled benefits to formulators looking for gentle polishing and whitening.

Compared to conventional perlite grades available on the market today, ImerCare® PerlWhite 19 offers the ideal balance between effective stain removal (Pellicle Cleaning Ratio) and minimum tooth wear (Relative Dentin Abrasion).

Due to its fine, platy, perlite particles, ImerCare® PerlWhite 19 improves cleaning at just a 1.5 to 2% loading.

ImerCare® PerlWhite 19 is inert and pH neutral so it does not have an effect on the pH of the toothpaste system and is compatible with other toothpaste ingredients, particularly therapeutic agents such as fluoride.

Clinical tests of ImerCare® PerlWhite 19 have been conducted by the Oral Health Research Institute at Indiana University, USA (detailed study available on request).


All Imerys cosmetic products are natural, high quality, chemically inert and offer good skin tolerance. They are not treated with chemicals during processing. These attributes enable them to be used in cosmetic products that comply with cosmetic directive regulation (EC) n° 1223/2009.
