The concentration of the sodium glycinate in an aqueous form in the non-precipitation regime was identified up to 2.0 mol{\^A}.L- 1. The coefficients of thermal expansion values were estimated from measured density data. It was found that, the densities, viscosities and refractive indices of the aqueous sodium glycinate decrease with an increase in temperature, whereas with increasing sodium glycinate concentration in the solution, all three properties increase. Thermal expansion coefficients slightly increase with rising temperature and concentration. The measured values of density, viscosity and refractive index were correlated as a function of temperature by using the least squares method. The predicted data obtained from correlation equations for all measured properties were in fairly good agreement with the experimental data. {\^A}{\copyright} 2014 The Chemical Industry and Engineering Society of China, and Chemical Industry Press.
