Ethanol

Ethanol (CAS 64-17-5), also designated E1510 in food applications and commonly abbreviated as EtOH, is a primary-grade alcohol produced through fermentation or synthetic routes. It functions as a solvent, carrier, preservative, and processing aid across a broad range of regulated and industrial markets. In pharmaceuticals, ethanol dissolves active ingredients and excipients.

It is used in oral liquids, tinctures, and topical formulations where controlled concentration and purity are critical to regulatory compliance. This ensures adherence to USP and BP standards. Personal care manufacturers use it as a fast-evaporating carrier in perfumes, hand sanitizers, and aerosol sprays. Its biocidal action also extends product shelf life in these applications.

Food and beverage producers rely on E1510 as a flavor carrier and extraction solvent, particularly in botanical extracts and aroma compounds. It meets Ph. Eur. requirements for safety. Printing and packaging operations use ethanol-based ink formulations for flexographic and gravure printing on flexible substrates. This is necessary where fast drying and low residual solvent levels are required.

Ethanol is supplied as a liquid in concentrations ranging from 70% to 99.9% (anhydrous). Recognized grades include food-grade and denatured technical grades governed by specific regional regulations. These regulations affect import and end-use eligibility for various industrial sectors. Bulk supply is available in drums, IBCs, and road tankers to meet high-volume manufacturing demands.
