Food Grade refers to materials, additives, or chemicals that are safe for human consumption and meet stringent purity and safety standards set by food regulatory authorities such as the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), or Codex Alimentarius. These substances are specifically approved for use in food production, processing, packaging, or preparation, ensuring they do not pose health risks when ingested.  Food-grade materials must be free from harmful contaminants, such as heavy metals, toxic residues, or pathogenic microorganisms, and they often comply with specifications like Food Chemical Codex (FCC) for purity. Examples include preservatives, flavorings, colorants, emulsifiers, and packaging materials (e.g., food-safe plastics or lubricants for machinery).

N-Propanol

N-Propanol, also known as n-Propyl Alcohol or 1-Propanol, is a clear, colorless, low-viscosity liquid with a characteristic mild alcohol-like odor. It is a primary alcohol with the molecular formula C₃H₈O, fully miscible with water and common organic solvents such as alcohols, ketones, ethers, glycols, and hydrocarbons. This high-purity, semi-volatile, polar solvent serves as both a versatile solvent and a chemical intermediate across multiple industrial sectors. N-Propanol has a flash point of 15–23°C and is classified as a highly flammable liquid. Technical grade N-Propanol is manufactured for industrial applications and is not intended for direct human consumption unless specifically certified as USP or Food Grade.
