Calamine Topical Suspension
» Prepare Calamine Topical Suspension as follows.
Dilute the Bentonite Magma with an equal volume of Calcium Hydroxide Topical Solution. Mix the powders intimately with the Glycerin and about 100 mL of the diluted magma, triturating until a smooth, uniform paste is formed. Gradually incorporate the remainder of the diluted magma. Finally add enough Calcium Hydroxide Topical Solution to make 1000 mL, and shake.
If a more viscous consistency in the Calamine Topical Suspension is desired, the quantity of Bentonite Magma may be increased to not more than 400 mL.
noteShake the Calamine Topical Suspension before dispensing.
Packaging and storage Preserve in tight containers.
