Description
Due to its fine, platy, perlite particles, ImerCare™ PerlWhite 19 improves polishing with a gentle abrasive effect that doesn’t damage teeth. This performance can be achieved with just 1.5 to 2% PerlWhite 19 in the formulation, offering formulators a cost-effective solution. ImerCare™ PerlWhite 19 is inert and pH neutral so it does not have an effect on the pH of the toothpaste system. A formulation by Imerys.
Procedure
- Hydrate Carbopol® into warm water and mix slowly for approximately 15 minutes (phase A).
- Pre-wet xanthan gum with glycerin and then hydrate with sorbitol. Mix well for 15 minutes to thicken and form a homogeneous dispersion (phase B).
- Combine phases A and B and mix for 10 minutes until smooth and homogeneous.
- Dissolve sodium monofluorophosphate and sodium saccharin in water (phase C).
- Add phase C to the mixture. Mix well for 10 minutes under vacuum to remove entrapped air.
- Add calcium carbonate and ImerCare™ PerlWhite 19, mixing slowly until fully incorporated into the gel base and then mix more rapidly to disperse throughout.
- Add the sodium lauryl sulfate and any color and flavouring into the beaker, mixing at low speed until homogeneous.
