Sodium Acetate USP United States Pharmacopoeia

Applications

Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning, and it helps to retard vulcanization of chloroprene in synthetic rubber production.

It is the chemical that gives salt and vinegar chips (crisps) their flavor. It may also be added to foods as a preservative; in this application it is usually written as "sodium diacetate" and labeled E262.

As the conjugate base of a weak acid, a solution of sodium acetate and acetic acid can act as a buffer to keep a relatively constant pH. This is useful especially in biochemical applications where reactions are pH dependent.

Traditional applications of this buffering agent include the leather tanning and dye industries. It is used in TANNING to effect a more even and rapid penetration of the tan. In the TEXTILE industry, it is considered a dye and color intermediate, with specific use as a mordant in the dyeing process. Because of its ability to remove insoluble calcium salts, sodium acetate is further used by the textile industry to improve the wearing quality of finished fabrics.

It is used soap making, plastic, medical & pharmaceutical industry. It is also used in phase change material and heat-packs. In petroleum industry it finds application as oil completion fluid and drilling muds. It is also used in cosmetics, water treatment and photography. It is a good buffer and it is used for deicing in cold countries.
