Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot. SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating.
This observation led, for example, the Food Standards Agency in the UK to propose upper limits of 200 mg/kg. [3] A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of ...
Cultural heritage collections contain many materials known to be hazardous to the environment and to human health. Some hazardous substances may be an integral part of the object (such as a toxic paint pigment or a naturally radioactive mineral sample), applied as a treatment after the object was made (such as a pesticide) or the result of material degradation (such as the exudation of ...

The U.S. Environmental Protection Agency said on Friday it had issued a final rule to prohibit the manufacture, import, processing and distribution of methylene chloride in all paint removers for ...
Tin(II) fluoride is added to some dental care products [111] as stannous fluoride (SnF 2). Tin(II) fluoride can be mixed with calcium abrasives while the more common sodium fluoride gradually becomes biologically inactive in the presence of calcium compounds. [112] It has also been shown to be more effective than sodium fluoride in controlling ...
The stannous ion, commonly added to toothpastes as stannous fluoride or stannous chloride, has been shown to have antibacterial effects in the mouth. Research has shown that stannous fluoride-containing toothpaste inhibits extracellular polysaccharide ( EPS ) production in a multispecies biofilm greater than sodium fluoride-containing ...
