A Comparative Study of the Hydroxyl Value and Iodine Value in Polyoxyl Stearyl Ether in United States Pharmacopeia Specifications

The iodine value (iodine number) and hydroxyl are important analytical characteristics of fats oils. (I2) required saturating the fatty acids present in 100 grams oil or fat. Iodine is a measure total number double bonds (-C=C-) Unsaturated compounds contain molecules with triple which very reactive towards iodine. has been determined according to Hanus monobromide glacial acetic acid, then amount remaining unreacted by titration using sodium thiosulfate volumetric standard solution. potassium hydroxide milligrams that equivalent 1 gram sample (mg KOH/g sample). Poloxyl Stearyl Ether mixture monostearyl ethers mixed polyethylene glycols. It may various amounts free stearyl alcohol some glycol. In this study, have polyoxyl ether. 1.84 g I2 absorbed/100g sample, 162.65 mg found poloxyl results met United States Pharmacopeia specifications for Polyoxyl Ether.
