Effect of Storage Length on Physical and Chemical Stability of Hair Growth Lotion Containing Candlenut Extract (Aleurites Moluccana L. Willd.)

This study investigated the effect of storage length on the physical and chemical stability of a hair growth lotion containing 5% candlenut extract. The lotion was formulated with varying concentrations of xanthan gum (0.5%, 1%, and 1.5%). The best formulation was found to be with 1% xanthan gum, which demonstrated optimal physical stability, including a latched power of less than 1 second, weekly increased viscosity, and no segregation, with an oil-in-water emulsion type. Although there was a decrease in flavonoid content after storage, it was not statistically significant (α = 0.58).
