Abstract

This study evaluated the effect of sodium chloride concentration on the physical stability of 1% gelatin colloidal dispersion. An experimental laboratory design was used with three formulas: F0 without sodium chloride, F1 with 2% sodium chloride, and F2 with 5% sodium chloride. Each formula was prepared in triplicate and evaluated through Tyndall effect intensity, coagulation onset, and sediment formation. All formulas showed visible light scattering, but the intensity decreased from strong in F0 to moderate in F1 and weak in F2.

Coagulation was not observed in F0, while F1 showed coagulation at approximately 32 minutes and F2 at approximately 55 minutes. These findings indicate that sodium chloride affects gelatin colloidal stability by changing particle interaction and promoting visible physical instability
