Краткий осмотр (реферат): | The aim of this work is to conduct a research analysis of changes in the structural and mechanical properties of the gel from the addition of active substances and surfactants.Materials and methods. In the presented work, model samples of the gel with active substances were studied: freshly obtained stonecrop juice, sea buckthorn oil, rosehip oil, St. John’s wort oil and quercetin. As substances for the man-ufacture of bases hydrocolloids of cellulose derivatives were used: sodium carboxymethylcellulose (NaCMC) and hydroxyethylcellulose (HEC) with a surfactant Lanette SX.A study of the rheological properties of the samples was performed using a rheoviscometer Rheolab QC (An-tonPaar, Austria) using a system of coaxial cylinders C-CC27/SS. The Rheolab QC rheometer is equipped with RheoPlus software, which allows you to set the necessary experimental conditions (shear rate gradient range, number of measuring points and measurement time of one point).Results. The rheological properties of model samples of NaCMC and HEC gels, depending on the used concen-tration, were studied. With increasing concentrations of both NaCMC and HEC thixotropy of dispersed systems decreases. The change of structural and mechanical parameters of hydrogels from the addition of active ingredi-ents and surfactant is analyzed, and established that adding them into the hydrogels increases the structural and mechanical parameters of model samples.A study of gels with a constant concentration of sodium carboxymethylcellulose and hydroxyethylcellulose and different content of surfactant Lanette SX established that as the surfactant concentration increases, the area of the hysteresis loop and the resistance of the dispersed system to the applied mechanical fracture increase.Conclusions. According to the results of the obtained structural and mechanical parameters and rheograms of the studied model samples of gels, it is rational to use in further studies of sodium carboxymethyl-cellulose (1.5%) and hydroxyethylcellulose (1.25%) stabilized Lannete SX in concentrations of 4–5% and 3–5% respectively |
