Use of calcium hydroxide topical solution
topical astringent, combination with other ingredients in dermatologic solutions and lotions to be applied locally
weight of calcium hydroxide in 100 mL solution
less than 400 mg
why is weight should be less than 400 mg for 100 mL solution?
Solution is intended to be saturated.
Why is sodium hydroxide allowed to settle at the bottom?
permits the solution to remain saturated should calcium hydroxide react with carbon dioxide in air to form calcium carbonate
calcium carbonate significance
maintains saturation of the solution
Storage of Calcium Hydroxide Topical Solution
stored in well-filled, tightly
stoppered containers to deter absorption of carbon dioxide
should be 25 degrees Celsius
