Sodium acetate is anhydrous powder and agglomerate. These two versions are chemically identical and
differ only in physical form. The agglomerate offers the properties of non-dustiness, improver wettability,
higher bulk density and improver free-flowability.

Packing
Sodium acetate anhydrous is supplied in woven lined paper bags.
Storageg andan handlingn
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.
First ai
Eye contact: In case of contact with eyes, rinse immediately with plenty of water and seek medical
advice.
Skin contact: Wash with water. Remove contaminated clothing, which should be washed before re-use.
Ingestion: Wash out mouth with water. Obtain medical attention.
Fire hazard
Sodium acetate presents little fire hazard.
Application
Sodium acetate anhydrous 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 (1).It is
also used in the production of dye stuffs, as a polymerization catalyst, as a polymer stabilizer, as a
flavoring agent, and in the manufacture of hydroxyl oxides, which are used as extractants in
hydrometallurgy.
(1) Detailed information on the use of sodium acetate for this application can be supplied on request.
