nonethanol

Nonethanol is a nonstandard term used in some contexts to denote products or formulations that do not contain ethanol. It is not an official chemical name or a distinct class of compounds, but rather a labeling shorthand that can appear in consumer goods, fuels, or other formulations to indicate the absence of ethanol.

In fuels, "nonethanol" or ethanol-free gasoline refers to fuel that contains little or no ethanol as an additive. This can be important for certain engines or equipment, particularly small engines that may be sensitive to ethanol blends (such as E10 or higher). In these contexts, nonethanol gasoline may be preferred for storage stability and to avoid potential ethanol-related issues.

In consumer products, labeling such as "ethanol-free" or "nonethanol" may appear on cosmetics, hand sanitizers, cleaners, and other formulations to indicate that ethanol is not used as a solvent or active ingredient. Such products may substitute other solvents or water as the primary medium. Availability and definitions can vary by region and by brand.

Regulatory and labeling considerations vary by jurisdiction. Some regions allow ethanol-free claims if ethanol is not added and any trace amounts fall below specified thresholds. Others require precise ingredient disclosure. Because there is no universal standard for "nonethanol," it is important for consumers to read ingredient lists or seek certification labels to understand what the term signifies in a given product.

Limitations include ambiguity and variability in meaning across markets. When precision is important—such as for dietary, medical, or engineering applications—explicit ingredients, proofs of absence, or compliance documentation should be consulted.
