Sodium Acetate

Sodium Acetate is a basic salt of acetic acid.  Sodium Acetate has many uses in food, like salt and vinegar chips, and is used to extend shelf-life in foods, as a pH control, and is safe to eat in low concentrations.  It is also used as a concrete sealant and for many other industrial uses. 

It acts as a leveling agent to maintain a pH of 4.5 to 5 in a dyebath.  So, for an acidic dyebath, the sodium acetate helps keep the fibers softer and reduce damage. 

Sodium Acetate combined with Potassium Aluminum Sulfate and hot water can be used to make Aluminum Acetate.
