Stearic Acid Water Solubility
How is the solubility of stearic acid in water? In ancient times, those who are good at studying physical properties have observed the solubility of stearic acid in water. Stearic acid, at room temperature, is insoluble in water. Its molecular structure has a long chain alkyl group, which is a hydrophobic group and has little affinity with water molecules. Although heating increases the water temperature, the solubility of stearic acid in water is slightly increased, but it is also limited. Water is a polar solvent, and stearic acid is strongly non-polar. According to the principle of similar miscibility, the two are not easy to dissolve. The solubility of stearic acid in water is low, and it is mostly dispersed and suspended in water, making it difficult to form a uniform and stable solution.
