Storage and handling

The product should be stored and handled in its original packaging or in a suitable sealed container and kept in a clean and dry place. Storage conditions should preferably be a sheltered environment with limited temperature variations and low humidity levels. Direct contact of the package with water or any other liquid is likely to cause the product to cake. Pallets should not be stacked. Under normal conditions, the use of this product does not cause any undue health hazard. Precautions should be taken to prevent eye-and prolonged or repeated skin contact with the solid product or its solutions.

Application

Sodium acetate trihydrate is used in the pharmaceutical industry, as a buffer in the photographic industry and as a supplement for animal feeds to increase the milk fat production of dairy cattle. It is also used in the production of dye stuffs, as a polymerization catalyst, as a polymer stabilizer, as a flavouring agent, and in the manufacture of hydroxyl oximes, which are used as extractants in hydrometailurgy. Detailed information on the use of sodium acetate for this application can be supplied on request.
