It should be applied in liberal quantities and remain in contact with excreta for at least 2 hr. Calcium hydroxide is now used in place of calcium oxide in prepn of lime water. Lime soaps formed by reaction of calcium hydroxide with vegetable oils are adhesive and are sometimes used as ointment base (lime liniment or "c oil").

Calcium chloride - Wikipedia
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2
