Overview
95% Ethanol, commonly referred to as 95% alcohol, is a high-purity form of ethyl alcohol widely utilized in various industries. It is a versatile solvent and disinfectant, known for its effectiveness in killing bacteria and viruses. The remaining 5% typically consists of water, which may be deionized or purified depending on the application. Ethanol at this concentration is favored in pharmaceutical manufacturing, laboratory settings, and industrial processes due to its balance of purity and cost-effectiveness. It is also used as a fuel additive and in the production of personal care products like hand sanitizers.
Physical and Chemical Properties
95% Ethanol is a clear, colorless liquid with a characteristic alcoholic odor. It has a density of approximately 0.816 g/cm³ at 20°C and a boiling point of 78.37°C, making it highly volatile. The compound is miscible with water and most organic solvents, which enhances its utility as a solvent in various formulations. Its molecular formula is C2H5OH, with a molecular weight of 46.07 g/mol. The presence of 5% water affects some properties, such as freezing point and evaporation rate, but does not significantly diminish its effectiveness in most applications.
Main Applications
In the pharmaceutical industry, 95% Ethanol is used as a solvent for drugs and in the preparation of tinctures and extracts. Its antiseptic properties make it a key ingredient in hand sanitizers and surface disinfectants, especially in healthcare settings. Industrially, it serves as a solvent for resins, oils, and other organic compounds. It is also used in the production of inks, dyes, and perfumes. Additionally, 95% Ethanol is employed as a fuel additive to improve combustion efficiency in certain engines.
Safety and Storage
Due to its high flammability, 95% Ethanol must be stored in tightly sealed containers away from heat sources and open flames. Proper ventilation is essential to prevent the accumulation of vapors, which can be explosive in high concentrations. Personal protective equipment (PPE), such as gloves and goggles, should be worn when handling this chemical to avoid skin and eye irritation. Spills should be cleaned up immediately with appropriate absorbent materials, and disposal must comply with local environmental regulations.
B2B Procurement Guide
When procuring 95% Ethanol, B2B buyers should prioritize suppliers with certifications such as ISO or GMP to ensure product quality and consistency. Bulk purchasing often reduces costs, but storage capacity and shelf life should be considered. It is advisable to request certificates of analysis (CoA) to verify purity and compliance with industry standards. Buyers should also assess the supplier's logistics capabilities to ensure timely and safe delivery, especially for large orders.
