Analytical Methods for Determining the Peroxide Value of Trivalin-SF 2-(2-Ethoxyethoxy) Ethanol by Current USP/NF <401>.

Abstract

The peroxide Value is the number that expresses, in milli equivalents of active oxygen, the quantity of peroxide contained in 1000 g of the substance. Peroxide Value of primary oxidation in oils and fats. Fatty acids break down during oxidation, forming peroxides that adversely affect taste, aroma, and nutritional value. Peroxide value is a useful tool for monitoring oxidation, but it’s typically combined with other methods for a fuller picture of the oxidation progress. USP/NF 2025 United States Pharmacopeia/ National Formulary and used as a verified reference method for peroxide determination. Peroxide values (POV) are standard tests in the food and cosmetic industry to ensure product quality and shelf-life. In this study, peroxide value in 2-(2-Ethoxyethoxy) ethanol has been determined by iodometric titration method using acetic acid-chloroform reagent. Peroxide value range is not more than 12.5 meq O₂/Kg. The average result is 8.75 meq O₂ / Kg. Relative repeatability Standard Deviation %RSD is 1.14 %. The average result meets the specification.
