Toothpaste

配方组成:

Plasticizer (Propylene Glycol)/20.00 % by wt
Lubricant (Mineral Oil, Heavy)/0.90 % by wt
Mix cellulose gum with one-fifth of combined humectants. Preheat
water to 70-80'C, then add to the wetted gum with rapid stirring. Add
remainder of the humectants and plasticizer. (When soap is used as a
foaming agent, it is added to the gum solution, heating if necessary to
dissolve it completely.) Cool the entire mixture to room temperature and
transfer to a Werner-Pfleiderer mixer. Add saccharin solution, oil of
peppermint, and mineral oil while mixing the gum solution. (When
synthetic detergent is used rather than soap, it is added at this point
while mixing the gum solution.)
Add abrasive slowly, allowing it to disperse well. After the abrasive is
added, mix until the paste appears homogeneous, usually from fifteen to
sixty minutes.
No.
Water/23.6 % by wt
Preservative ("Tegosept" M)/0.1 % by wt
Flavor (Saccharin Solution, 50%)/0.1 %

配制方法:

Dissolve sodium lauryl sulfate in one-third of the water. Mix the "Sorbo," sodium saccharine, and 6% "Carbopol" solution with the rest of the water. This will be a thin solution. Blend the two solutions carefully to avoid foaming. Slowly add the sodium hydroxide to neutralize the "Carbopol 934" while gently stirring. The solution will become thick as the neutralization progresses. Slowly mix in the calcium phosphate. Stir until the particles are wetted out and all the lumps are broken up. Mill and deaerate the batch on conventional equipment. Add the flavoring during the last stages of milling to avoid evaporation loss. Fill into tubes.
