 Hydroxyethyl cellulose's solubility in water is a result of the hydroxyethyl groups attached to the cellulose backbone. These hydroxyethyl groups make HEC more soluble in water compared to native cellulose, which is highly insoluble. The degree of substitution, or the number of hydroxyethyl groups per anhydroglucose unit, significantly influences the solubility. Higher degrees of substitution lead to better water solubility, as they enhance the hydrophilic nature of the polymer. Hydroxyethyl cellulose (HEC) is a versatile and widely used polymer in various industries such as pharmaceuticals, cosmetics, food, and construction. It is a non-ionic, water-soluble polymer derived from cellulose, which is a natural polymer found in plants.

HPMC gilt als unbedenklich für den menschlichen Verzehr. Da HPMC vom Körper wie ein wasserlöslicher Ballaststoff unverdaut ausgeschieden wird, kann er ohne Bedenken und ohne Einschränkung zu sich genommen werden. Normalerweise gibt es für die Verträglichkeit von Lebensmittelzusatzstoffen einen sogenannten ADI-Wert (acceptable daily intake). Dieser Wert gibt die Tagesdosis an, die bei lebenslanger täglicher Einnahme als medizinisch unbedenklich betrachtet wird. Der ADI-Wert wird durch das Bundesinstitut für Risikobewertung sowie der Europäischen Behörde für Lebensmittelsicherheit (EFSA) festgelegt. Für HPMC gibt es keine Beschränkung der Höchstmenge, also auch keinen ADI-Wert.
