SODIUM ALUMINUM SULFATE Chemical Properties,Usage,Production

Chemical Properties

Colorless crystals; saline, astringent taste; effloresces in air. Soluble in water, insoluble in alcohol. Noncombustible.

Uses

Sodium Aluminum Sulfate is a leavening agent that releases the majority of the gas during baking, and is not used alone but in com- bination with a faster-acting leavening agent such as monocalcium phosphate. this results in a double-acting baking powder. it is almost nonreactive until heat is applied. it is used in baked goods.

Uses

Aluminum Sodium Sulfate is a general purpose food additive that functions as a buffer, neutralizing agent, and firming agent. It is anhydrous and slowly soluble in water. The dodecahydrate form is readily soluble in water. It is also termed soda alum.

General Description

A colorless crystalline solid. Used in textiles, paper making, water purification, food processing.

Air & Water Reactions

Solid effloresces in air. Water soluble.

Reactivity Profile

SODIUM ALUMINUM SULFATE gives acidic solutions in water.

Health Hazard

Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Safety Profile

A weak sensitizer. A general-purpose food addtive. Local contact may cause contact dermatitis. An irritant. See also SULFATES and ALUMINUM COMPOUNDS. When heated to decomposition it emits toxic fumes of SO, and Na2O.
