The present invention provides a method for removal of gypsum from the skin of a patient. The method comprising the steps of: (i) applying to the skin of a patient an aqueous liquid composition comprising a water-miscible organic solvent, an acid and an emollient, the aqueous liquid composition having a pH in the range of from about 2 to about 5; (ii) dissolving the gypsum in the aqueous liquid composition; and (iii) removing the aqueous liquid composition containing dissolved gypsum from the skin of the patient. An aspect of the invention also relates to a liquid composition, particularly one for removal of gypsum from the skin of a patient, the composition comprising water, a water-miscible organic solvent, an acid and an emollient, the liquid composition having a pH in the range of from about 2 to about 5, with the proviso that the acid is not salicylic acid. The method and composition are particularly well suited for removal of gypsum deposits from the skin of a patient after removal of a Plaster of Paris-based cast from the patient.
A method for removal of gypsum from the gypsum skin of patient comprising the steps of:
A liquid composition for removal of gypsum from the gypsum skin of a patient, the composition consisting essentially of water, a water-miscible organic solvent, from about 1.7 to about 5.0 percent by weight of an organic acid having a pK.sub.a in the range of from about 1.0 to about 5.0 and from about 0.5 to about 5.0 percent by weight of an emollient, the liquid composition having a pH in the range of from about 2.0 to about 5.0, with the proviso that the acid is not salicylic acid.
