In addition to its thickening properties, hydroxyethyl cellulose also enhances the stability of paint formulations. HEC acts as a stabilizer, preventing the separation of components and maintaining emulsion stability over time. This characteristic is essential for ensuring that paints remain consistent in their performance throughout their shelf life. As a result, manufacturers can produce paint products with extended durability, reducing the need for reapplication and thus benefiting consumers and the environment alike.

The degree of substitution (DS) is another vital parameter used to categorize HPMC grades. It refers to the average number of hydroxyl groups in the cellulose molecule that are replaced by hydroxypropyl and methyl groups. A higher DS generally correlates with increased hydrophobicity and a reduction in solubility in cold water. Therefore, formulations requiring faster solubility may leverage lower DS grades, while those needing delayed release or thicker consistency might benefit from higher DS grades.
