What is Disodium Ethylenebisdithiocarbamate?
Disodium ethylenebisdithiocarbamate (DEDC) is a dithiocarbamate-based chemical compound with the CAS number 142-59-6. It belongs to a class of organic compounds containing sulfur and nitrogen that exhibit antimicrobial properties. The compound is structurally related to other dithiocarbamates used in agricultural and industrial applications. DEDC functions by disrupting microbial cell processes, thereby preventing or slowing the growth of bacteria, fungi, and other microorganisms.
Common Uses
Disodium ethylenebisdithiocarbamate has been investigated for use as a food preservation agent, particularly in applications where antimicrobial activity is desired. However, its use in food products is severely limited in most major regulatory jurisdictions. The compound has found greater application in agricultural fungicide formulations and non-food industrial processes. In regions where it may be permitted, potential applications in food have been limited to specific preservation scenarios, though such use remains uncommon in commercial food manufacturing.
Safety Assessment
The safety profile of disodium ethylenebisdithiocarbamate in food applications has not been extensively established through modern toxicological testing. The FDA has not granted GRAS (Generally Recognized As Safe) status for this compound as a food additive. According to FDA records, there are currently zero reported adverse events associated with this substance and zero recalls attributed to its use in food products. However, the absence of adverse event reports does not constitute approval or confirmation of safety; rather, it may reflect limited commercial use in food applications.
Dithiocarbamates as a class have raised concerns in some scientific literature regarding potential health effects, including reproductive and developmental considerations. The European Food Safety Authority (EFSA) and other regulatory bodies have evaluated related dithiocarbamate compounds with varying conclusions. Individual dithiocarbamates have different safety profiles, and assessments cannot be automatically transferred between compounds in this class.
Regulatory Status
Disodium ethylenebisdithiocarbamate is not approved for use as a food additive in the United States under FDA regulations. It does not appear on the FDA's list of permitted food additives and has not received GRAS affirmation. In the European Union, this compound is not listed as an approved food additive under Regulation (EC) No 1333/2008. Many other countries similarly do not permit its use in food products intended for human consumption.
The compound may be permitted in some jurisdictions for non-food agricultural or industrial uses, where different regulatory frameworks apply. Food manufacturers seeking to use antimicrobial agents must select from FDA-approved alternatives such as sodium benzoate, potassium sorbate, or other established preservatives with documented safety histories.
Key Studies
Scientific literature on disodium ethylenebisdithiocarbamate specifically as a food additive is limited. Most available research focuses on related dithiocarbamate compounds or addresses non-food applications. Toxicological studies on dithiocarbamates in general have been conducted, but compound-specific data for DEDC in food contexts remains sparse in peer-reviewed literature.
Regulatory decisions by major food safety authorities to not approve this substance suggest that available safety data has been deemed insufficient or that identified concerns outweigh potential benefits. The lack of FDA GRAS status indicates the compound has not met the stringent standards required for food use in the United States.
