Dehydrates and degreases cavities. Composition: Acetone 37.60 g Ethyl acetate 42.80 g Excipients qs ad 100.00 g Indications: Alcohol, acetone or chloroform, which have hitherto been used for drying cavities, have two inconveniences: They do not always remove the grease present in cavities. They are contra-indicated for some fillings or linings (porcelains, resins, etc.). Hydrol removes simultaneously moisture and all traces of grease. Hydrol can be used with any type of filling or lining material. Hydrol, economical in use, solves conclusively one of the practitioner's constant problems. Directions for use: Dab the area to be dried with a cotton ball soaked in Hydrol. Wait a few seconds for the complete evaporation of the fluid.
