A hidroxietilcelulose, outro \u00e9ter de celulose popular, difere da HPMC na sua estrutura qu\u00edmica e nas suas propriedades. Embora ambos sejam sol\u00faveis em \u00e1gua e formem solu\u00e7\u00f5es viscosas, o HPMC oferece geralmente uma melhor estabilidade t\u00e9rmica e capacidades de forma\u00e7\u00e3o de pel\u00edcula.

A metilcelulose, o composto de origem do HPMC, partilha muitas semelhan\u00e7as com o seu derivado. No entanto, o HPMC oferece normalmente uma melhor solubilidade em \u00e1gua quente e fria, bem como uma maior estabilidade na presen\u00e7a de sais e outros compostos i\u00f3nicos.
