Procedure

  • Hydrate Carbopol in warm water and mix slowly for 15 min.
  • Pre-wet Xanthan Gum with Glycerin and then hydrate with Sorbitol. Mix well for 15 min to thicken and form a homogeneous dispersion (phase B).
  • Combine phases A and B and mix for 10 min until smooth and homogeneous.
  • Dissolve Sodium Monofluorophosphate and Sodium Saccharin in water (phase C).
  • Add phase C to the blend. 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 colour and flavouring into the beaker, mixing at low speed until homogenised.
