Magnesium sulfate heptahydrate, also known as sulfuric acid, bitter salt, cathartic salt, and laxative salt (chemical formula: MgSO47H2O), is a white or colorless needle-like or oblique columnar crystal, odorless, cool, and slightly bitter. It decomposes upon heating, gradually losing its crystal water to become anhydrous magnesium sulfate. It is mainly used in the manufacture of fertilizers, leather, printing and dyeing, catalysts, paper, plastics, porcelain, pigments, matches, explosives, and fireproof materials. It can be used to print and dye thin cotton and silk fabrics, as a weighting agent for cotton and silk, and as a filler for kapok products. In medicine, it is used as a laxative salt.
