Lead(II) acetate(Pb(CH3COO)2), also known as lead acetatelead diacetateplumbous acetatesugar of leadlead sugarsalt of Saturn, or Goulard's powder, is a white crystalline chemical compound with a sweetish taste. With water, it forms the trihydrate, Pb(CH3COO)2·3H2O, a colourless or white efflorescent monoclinic crystalline substance. The substance is used as a reagent to make other lead compounds and as a fixative for some dyes. In low concentrations, it is the principal active ingredient in progressive types of hair colouring dyes.[6] Lead(II) acetate is also used as a mordant in textile printing and dyeing, and as a drier in paints and varnishes. It was historically used as a sweetener and for cosmetics.
