| Sodium omadine Usage And Synthesis |
| Chemical Properties | Clear solution |
| Uses | For chemistry of 2-mercaptopyridine-N-oxide, see Aldrichimica Acta.1 |
| Uses | sodium pyrithione is a preservative that is not commonly used because of some level of toxicity. It is prohibited in Canada, and it is on the eu Annex II list of substances that must not form part of a cosmetic product composition. |
| Uses | Sodium omadine is a bactericide for use in cooling fluids and short-term in-can preservation of vinyl acetate latex, paints, and synthetic-fiber lubricants; preservative for cosmetic rinse-off products. |
| Definition | Apparently exists in equilibrium with the -SH form. Forms chelates with iron, manganese, zinc, etc. |
| Brand name | Sodium Omadine (Olin). |
| Safety Profile | Poison by intraperitoneal and intravenous routes. Moderately toxic by ingestion, subcutaneous and parenteral routes. Used in preservation of cosmetics. When heated to decomposition it emits very toxic fumes of Na2O, NOx, and SOx. See also MERCAPTANS. |
| Purification Methods | When recrystallised from water, it assayed as 98.7% based on AgNO3 titration [Krivis et al. Anal Chem 35 966 1963; see also Krivis et al. Anal Chem 48 1001 1976, and Barton & Crich J Chem Soc, Perkin Trans 1 1603, 1613 1986]. [Beilstein 21/7 V 151.] |
