[¦eth·ə·lēn¦dī·ə‚mēn‚te·trə·ə′sēd·ik ′as·əd]
(organic chemistry)
(HOOC-CH2)2NCH2CH2N(CH2COOH) White crystals, slightly soluble in water and decomposing above 160°C; the sodium salt is a strong chelating agent, reacting with many metallic ions to form soluble nonionic chelate. Abbreviated EDTA.

The DPNR latex was prepared by treating FNR latex with ethylenediaminetetraacetic acid sodium (EDTA-Na), ethylenediaminetetraacetic acid disodium (EDTA-2Na), ethylenediaminetetraacetic acid trisodium (EDTA-3Na), and ethylenediaminetetraacetic acid tetrasodium (EDTA-4Na) at various concentrations (0.05, 0.10, 0.20 wt%) in the presence of 1wt% sodium dodecyl sulfate (SDS) at room temperature for 1 h with continuous stirring.

Suggestions comprise the application of some major active components instead of the whole oil; the development of synergistic combinations between two EOs or between an EO and another antimicrobial; the combination of EOs with chelating agents, such as ethylenediaminetetraacetic acid (EDTA) (although EDTA is not a preservative, it may potentiate other antimicrobials); the employment of EOs with dispersing agents, such as polyethylene glycol, to increase contact with microbial cells, especially in food with high lipid contents.
