We will introduce a case where the raw extract of sunscreen cream was taken and TD-NMR measurements were conducted.
We would like to introduce a case study conducted by Majerika Japan Co., Ltd. regarding the measurement of the raw material of sunscreen cream. To determine the suitable pressure for the jet mill, we measured the viscosity and relaxation time of the sunscreen cream. The relaxation time was converted to dispersion degree (%) for comparison. A correlation was obtained between viscosity and dispersion degree. With pulse NMR, even at high concentrations, the dispersion endpoint can be evaluated in a short time simply by transferring it directly into the NMR tube without dilution. 【Case Overview】 ■ Experiment - The raw material of the sunscreen cream was extracted, and TD-NMR measurements were conducted. ■ Results - The relaxation time was converted to dispersion degree (%) for comparison. - A correlation was obtained between viscosity and dispersion degree. *For more details, please refer to the PDF document or feel free to contact us.
