Uses:

Medicine and Healthcare

In the pharmaceutical industry, anhydrous ethanol is an indispensable solvent, extractant, and reaction medium in drug manufacturing. Many esterification and etherification reactions in drug synthesis need to be carried out under anhydrous conditions to avoid interference from water molecules or the formation of by-products.

Chemistry and Industrial Synthesis

Anhydrous ethanol is an important raw material and solvent in the synthesis of many fine chemicals. In organic synthesis, it serves both as a reaction medium and an alkylating reagent in the construction of carbon-oxygen and carbon-carbon bonds.

Energy and Fuel Applications

Fuel ethanol is an important component in the renewable energy sector. Anhydrous ethanol, due to its extremely low water content, can well mix with gasoline and is thus a key component of ethanol gasoline (such as E10, E85, etc.).

Cosmetics and Food Industry

Although ethanol is generally used in food as edible alcohol, high-purity anhydrous ethanol is also used in some high-end food extraction processes, such as the extraction of plant essential oils, spices, and pigments. Due to its almost no water content, it can better retain heat-sensitive aromatic components and is suitable for the preparation of natural flavors and high-end seasonings. In the cosmetics industry, anhydrous ethanol is often used as a solvent and preservative in perfumes, sprays, and skin care products, helping active ingredients penetrate and improving product stability. It should be noted that due to its strong demulsifying property, moisturizing components are often added to the formula to reduce irritation to the skin.‌
