WebApr 7, 2024 · Along with increased purity, a slow crystallization process also encourages the growth of larger crystals. Figure 3.17 shows crystallization of acetanilide from water with two different rates. The crystals grown in Figure 3.17a were formed much more quickly, and are smaller than the slower grown, larger crystals in Figure 3.17b. WebIt happens because the glycerin draws moisture to the surface of the soap, which then evaporates and leaves crystals behind. Melt and pour soap bases often have various salts added to regulate the pH, add structure, regulate moisture or help with stability. Sodium stearate and sodium citrate are very common additives that could crystallize, but ...
