Exposure Standards and Regulations
Substance added directly to human food affirmed as generally recognized as safe (GRAS).
Sodium diacetate used as a sequestrant in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice.
Drug products containing certain active ingredients offered over-the-counter (OTC) for certain uses. A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses: sodium diacetate is included in astringent drug products.
Other Preventative Measures
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Protective Equipment and Clothing
Causes eye irritation.
Specification

? Sodium diacetate , with CAS number of 126-96-5, can be called Acetic acid dimer, sodium salt ; Acetic acid, sodium salt (2:1) ; Acetic acid, sodium salt, compd. with acetic acid (1:1) ; Acid acetate ; Sodium acetate (1:2) ; Sodium acetate, acid ; Sodium acetate, compd. with acetic acid (1:1) ; Sodium acid acetate ; Sodium hydrogen diacetate .

Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
