Chemically Distilled Ethanol Anhydrous (CDEA) is ethanol purified to contain minimal water content, typically less than 0.1%. This near-absolute ethanol form enhances its chemical stability and reduces interference from moisture-sensitive processes. Its purity level is essential in contexts where residual water could alter reactivity, dissolution rates, or product stability.
Ethanol’s molecular formula C2H6O indicates a structure conducive to both polar and non-polar solvent interactions. This dual affinity allows CDEA to dissolve a broad spectrum of compounds, from polar pharmaceutical ingredients to hydrophobic cosmetic oils. The chemically distilled aspect refers to the method of purification, which involves fractional distillation under controlled conditions to remove water and other volatiles. This process differs from standard ethanol distillation by targeting near-complete water removal, making CDEA suitable for applications demanding absolute ethanol quality.
Functionally, CDEA acts by breaking intermolecular bonds in solutes, facilitating their dissolution, and then evaporating cleanly without leaving residues. This is critical in pharmaceutical solvent roles, where residual moisture can degrade active pharmaceutical ingredients or influence dosage form consistency. Industrially, CDEA cleans surfaces by dissolving oils, greases, or contaminants, then rapidly evaporates to leave no trace.
Its volatility and flammability require safe storage in cool, ventilated areas away from sources of ignition. The clear colorless liquid is standardized by CAS Number 64-17-5 and chemical name Ethanol, ensuring consistency in procurement. Although exact purity and grade depend on batches and are confirmed with the supplier, Zenco Systems Ltd prioritizes delivering ethanol that meets industrial and pharmaceutical standards, supporting reliable supply chains across East Africa.
