Green solvents from ionic liquids and deep eutectic solvents to natural deep eutectic solvents

Open access

Abstract

Natural deep eutectic solvents (NADESs) are defined as mixtures of certain molar ratios of natural compounds such as sugars, organic acids, amino acids, and organic bases that are abundant in organisms. The melting points of these mixtures are considerably lower than those of their individual ingredients and far below ambient temperature. The first publications on the NADES concept in 2011 created a great expectation regarding their potential as green solvents that could replace conventional organic solvents in a wide range of applications. This was largely because many of the drawbacks of conventional synthetic ionic liquids (ILs) and deep eutectic solvents (DESs), particularly their toxicity and environmental hazards, could be solved using NADESs. Throughout the last 7 years, the interest in NADESs has increased enormously as reflected by the exponential growth of the number of related publications. The research on NADESs has rapidly expanded particularly into the evaluation of the feasibility of their application in diverse fields such as the extraction of (targeted) bioactive compounds from natural sources, as media for enzymatic or chemical reactions, preservatives of labile compounds, or as vehicles of non–water-soluble compounds for pharmaceutical purposes. Along with the exploration of these potential applications, there have been a large number of other studies related to their physicochemical features, the search for new NADESs, the research into the interactions between NADES components or with solutes, the recovery of solutes from NADES solutions, and the ways of circumventing inherent problems of NADESs such as their high viscosity and the consequent difficulties in handling them. This article contains a review of the applications of NADESs as extraction solvents, reaction media, and preservative, providing also a perspective of their future.

  • The paper relies on this without support.

    ILs and DESs have toxicity and environmental hazards that NADESs can solve.

    “This was largely because many of the drawbacks of conventional synthetic ionic liquids (ILs) and deep eutectic solvents (DESs), particularly their toxicity and environmental hazards, could be solved using NADESs.”
  • The paper relies on this without support.

    NADESs have a real physiological or biological role in living organisms.

    “Natural DESs or ILs, known as NADESs, have been proposed as a different alternative for two reasons: their ingredients are sourced from nature and they are believed to have a real physiological or biological role in nature.”
  • The paper relies on this without support.

    NADES components are safe, nontoxic, and edible.

    “As mentioned above, the fact that NADES components are safe, nontoxic, and even edible, allows NADESs to be considered for pharmaceutical, cosmetic, and food applications”
  • The paper relies on this without support.

    NADESs can dissociate in contact with biofluids, allowing dissolved compounds to precipitate.

    “However, before considering NADESs as drug delivery systems, it is important to bear in mind that they might dissociate in contact with biofluids.Thus, even if a compound was totally dissolved in an NADES, it could precipitate when the NADES dissociates in the organism.”
  • The paper relies on this without support.

    NADESs have lower reactivity than ILs.

    “considering the low reactivity of NADESs compared to that of ILs.”
  • The authors state this as an assumption.

    NADESs exist as a third liquid phase in cells of all organisms.

    “In our first article [1], we introduced the hypothesis of NADESs as a third liquid phase in cells of all organisms, presenting indirect evidence for their presence in plants.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-09-30, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-09-30 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
