The solubility of HPMC in cold water depends on several factors, including the degree of substitution (DS), molecular weight, and the specific grade of the polymer. Generally, HPMC with a higher degree of substitution is more soluble in cold water. The presence of hydrophilic groups increases the interaction with water molecules, promoting dissolution. Additionally, lower molecular weight HPMC grades tend to dissolve more readily than higher molecular weight grades due to reduced chain entanglement.
