Scope

Scope: This standard specifies the requirements, test methods, inspection rules, and packaging, labeling, transportation, and storage for the cosmetic raw material, Octylhydroxamic Acid. This standard applies to crystalline powder products of Octylhydroxamic Acid used in cosmetics. Main technical content: 1. Test methods 1.1 Determination of content: Using the adsorption and desorption of Octylhydroxamic Acid on the stationary phase of high-performance liquid chromatography, the retention time is used for qualitative determination and the peak area for quantitative determination. 1.2 Determination of melting point: Determined according to the "Pharmacopoeia of the People's Republic of China (2020 Edition, Part IV)" 0612 "Determination of Melting Point". 1.3 Determination of color: Compared with the standard platinum-cobalt comparison solution in GB/T 3143-1982 "Determination of Color in Liquid Chemical Products (Hazen Units - Platinum-Cobalt Number)". 1.4 Determination of pH value: Weigh an appropriate amount of the sample into a sample bottle, add newly boiled and cooled deionized water to prepare a 0.2% aqueous solution of Octylhydroxamic Acid. Place it in a constant-temperature water bath at 50°C until the solid is completely dissolved. Remove it and cool to room temperature. After filtration, add 0.03ml of saturated potassium chloride solution to 10ml of the solution and mix well. Prepare two parallel samples. Determine the pH value according to the provisions of GB/T 9724 "General Methods for Determination of pH Value of Chemical Reagents". 1.5 Determination of moisture: Determined according to the "Pharmacopoeia of the People's Republic of China (2020 Edition, Part IV)" 0832 "Determination of Moisture (Method III - Vacuum Drying)". 1.6 Determination of ash: Determined according to the provisions of GB/T 9741 "General Methods for Determination of Ash in Chemical Reagents". 1.7 Determination of mercury: Determined according to the provisions of "Technical Specif
