lead acetate, chemical compound, a white crystalline substance with a sweetish taste. Like other lead compounds, it is very poisonous. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(CH3COO)2·3H2O, a colorless or white efflorescent monoclinic crystalline substance that is commonly known as sugar of lead, plumbous acetate, or Goulard's powder. Lead acetate is used as a mordant in textile printing and dyeing, as a drier in paints and varnishes, and in preparing other lead compounds. It is made by treating litharge (lead monoxide, PbO) with acetic acid. lead acetate [′led ′as·ə‚tāt] (organic chemistry) Pb(C2H3O2)2·3H2O Poisonous, water-soluble white crystals decomposing at 280°C; loses water at 75°C; used in hair dyes, medicines, and textile mordants, for waterproofing, for manufacture of varnishes and pigments, and as an analytical reagent.

They note that the presence of tin oxide was unusual because Roman cosmetic creams typically contained lead acetate. Data suggest that rats dosed with relatively high levels of lead acetate for short periods of time induced changes in the hypothalamic gonadotropin-releasing hormone (GnRH) at the molecular level, but these changes were attenuated with increased concentration of exposure. For instance, zinc oxide is also used as a color additive in cosmetics, and lead acetate appears in Grecian Formula, a hair coloring product. |
