Glutathione's Solubility Profile: Beyond Ethanol

While this article focuses on ethanol, it's important to note that glutathione solubility varies significantly across different solvents. Generally, reduced glutathione is freely soluble in water, a property crucial for its biological functions and many aqueous-based formulations like intravenous preparations or skincare products. Its solubility in water is often cited as around 50 mg/mL or even higher, with some sources indicating over 200 mg/mL.Glutathione powder is soluble in water, dilute alcohol and dimethylformamide butinsoluble in ethanol.

However, when it comes to organic solvents, the picture becomes more nuanced. For instance, it demonstrates varying degrees of solubility in dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO), often with reported solubilities around 10 mg/mL for DMF and sometimes described as soluble in water, DMSO or ethanol. This contrasts with its insolubility in less polar solvents like diethyl ether or acetone.Glutathione - Physico-chemical Properties ; Solubility, Soluble in water, dilute alcohol, liquid ammonia, dimethylformamide,insoluble in ethanol, ether, acetone ...

Glutathione Solubility in Ethanol: A Closer Look

The solubility of glutathione in ethanol is a subject with a range of reported findings, indicating that conditions and the specific form of glutathione can influence the outcome. Several sources state that glutathione is insoluble in ethanol. This is a critical piece of information for any application where ethanol is a primary solvent. For example, one data point explicitly mentions "Ethanol : Insoluble.Extraction of Glutathione from EFB Fermentation Waste ..." Another report indicates "Glutathione powder is soluble in water, dilute alcohol and dimethylformamide but insoluble in ethanol."

Conversely, some research indicates a degree of solubility, albeit often described as limited. For instance, one product specification lists solubility in ethanol at 5 mg/mL, while another mentions "very slightly soluble in ethanol" or "slightly soluble in ethanol." Furthermore, one study on the dissolution thermodynamics and polymorphic behavior mentions using binary mixed solvents including ethanol + water for determining GSH solubility. This suggests that in a mixture with water, ethanol can be part of a solvent system where glutathione exhibits some solubility4.2.3Solubility. 292.5 mg/mL.

Another important consideration is the purity and form of the glutathione. For example, L-Glutathione oxidized is described as soluble in water, DMSO or ethanol, which might imply a difference compared to the reduced form. Similarly, some product descriptions differentiate between forms, with one noting "freely soluble in water, very slightly soluble in ethanol(96 per cent)".

The distinction between dilute alcohol and pure ethanol is also significant. Several sources highlight that glutathione is freely soluble in water, dilute alcohol, further emphasizing that higher concentrations of alcohol, like pure ethanol, can decrease its solubility. The question of "What is the concentration of dilute alcohol and what is its max solubility in dilute alcohol?" highlights this important clarification.2025年8月18日—Solubility, Freely soluble in water,very slightly soluble in ethanol, Complies.

Factors Affecting Glutathione Solubility in Ethanol

Several factors can influence the observed solubility of glutathione in ethanol:

* Temperature: As with most chemical compounds, temperature can affect solubility. Higher temperatures generally increase solubility, though specific data for glutathione in ethanol at various temperatures is not extensively detailed in the provided data.

* Presence of Other Solvents: As noted in the mixed solvent studies (ethanol + water), the presence of a co-solvent, particularly water, can significantly enhance the solubility of glutathione in ethanol作者：M Muryanto·2017·被引用次数：16—Some research was conduct to obtainglutathionecompound from yeast by maceration extraction use variation solvents such asethanol25% [10],ethanol40% [11], ....

* pH: While not explicitly detailed for ethanol solutions, pH is a critical factor in the solubility of many compounds, especially those with ionizable groups like glutathione.

* Form of Glutathione: Oxidized vs. reduced glutathione may exhibit different solubility profiles.

Practical Implications and E-E-A-T Considerations

Understanding glutathione solubility in ethanol is vital for various applications, including:

* Formulation Development: For pharmaceutical, cosmetic, or nutraceutical products where ethanol might be used as a solvent or co-solvent, knowing the solubility limits is crucial for achieving stable and effective formulations. If glutathione is poorly soluble in ethanol, alternative solvents or formulation strategies (like nanoemulsions for improved stability) may be necessary.Glutathione - Regulations.gov

* Chemical Synthesis and Extraction: In laboratory settings or industrial processes involving the synthesis or extraction of glutathione, solvent choice directly impacts yield and purity. For instance, the recrystallization of glutathione from "50% ethanol" suggests its use in purification processes where controlled solubility is keyGlutathione Powder 98% | The Glory of Asia Industrial Company.
