Toothpaste/Dental Whitening Cream Manufacturing

Learn how Quadro's Powder Disperser provides the perfect solution for manufacturers of Toothpaste and Dental Whitening Creams.

Background / Requirement

  • Incorporation of Carbopol and 40% Carbamide Peroxide into Glycerine
  • Carbopol is difficult to disperse into Glycerine because the low pH Glycerine solution results in instant hydration and viscosity increase
  • 40% by weight Carbamide Peroxide is added to the Carbopol solution in a recirculation to the mixing vessel
  • Need to increase production without expanding the facility.

Quadro’s Approach to manufacturing toothpaste

ZC1 inline disperser, skid mounted with a dual PD pump arrangement for performance with high viscosities and high solids addition rates and automated Q-Vac vacuum powder addition system

  • Controls to allow (3) pre-set operating points on inlet and discharge pumps
    • Carbopol addition
    • Carbamide Peroxide addition
    • Auxiliary setting

Automated powder valve with level sensors in the hopper to control powder on/off addition.

Quadro YTron® ZC Powder Disperser Advantages

  • 75% reduction in overall batch time vs. conventional in-tank mixer processing
  • Rapid incorporation & dispersion of solids without lumps or ‘fish-eyes’
  • Improved product consistency from batch to batch
  • Increase in viscosity, the customer was able to reformulate and use less polymer
  • Eliminated requirement to filter undispersed powders
  • No over-processing is common with conventional mixers preserving the rheological properties of shear-sensitive products
  • Significantly reduced air entrainment
  • Elimination of quality problems associated with cross batch contamination
  • No excessive dusting from bag dumping into process vessels
  • No solids build-up on process vessel walls
  • Elimination of the requirement to expand the manufacturing area to increase production.
