For procurement managers, R&D scientists, and product formulators, selecting the correct grade and purity of ethanol is a critical decision that impacts product performance, regulatory compliance, and cost. With its CAS number 64-17-5, ethanol is available in a spectrum of specifications, and understanding these nuances is key to making informed purchasing choices. This guide, from your trusted manufacturer and supplier in China, demystifies ethanol specifications.

The term 'Absolute Ethanol' is commonly used to denote a very high purity grade, typically 99.5% or higher. This is essential for applications where minimal water content is critical, such as in certain chemical syntheses, as a dehydrating agent, or in specific laboratory reagents. When you buy absolute ethanol, you're investing in a product that minimizes interference from impurities.

Beyond 'absolute,' ethanol is categorized by its intended use, dictating its purity and any additives. Industrial Grade Ethanol is a broad category, often denatured to make it unfit for human consumption, thus avoiding excise duties. These grades are suitable for a vast range of applications including solvents for paints, inks, and adhesives, as well as in cleaning products and as a fuel additive. As a significant supplier, we provide various industrial grades tailored to specific process needs.

Pharmaceutical Grade Ethanol (USP/EP/BP compliant) demands exceptionally high purity and is manufactured under strict Good Manufacturing Practice (GMP) guidelines. It's used in drug formulations, as an antiseptic, and in medical devices. When procuring for the healthcare sector, ensuring compliance with pharmacopoeia standards is non-negotiable. We pride ourselves on being a reliable manufacturer of pharmaceutical-grade ethanol.

Food Grade Ethanol, often referred to as 'neutral spirits' or 'grain alcohol,' is produced with stringent controls to ensure it is safe for consumption and use in food products. It's utilized in flavorings, extracts (like vanilla and citrus), as a preservative, and in the production of alcoholic beverages. For these applications, sourcing from a supplier in China with robust food safety certifications is crucial.

The price of ethanol can vary significantly based on its grade and purity. Higher purity grades, especially those meeting pharmaceutical or food-grade standards, naturally command a higher price due to the more intensive manufacturing and quality control processes involved. When seeking quotes, be specific about the grade and purity you require to get accurate ethanol pricing.

Understanding these specifications empowers you to make the right choice. Whether you need high-purity ethyl alcohol for a critical pharmaceutical application or a cost-effective industrial grade for solvent use, partnering with an experienced ethanol manufacturer who can clearly articulate their product's specifications is vital for your business success.
