  • 2. Degree of Substitution As mentioned earlier, the degree of substitution (DS) refers to the number of hydroxyl groups on the cellulose molecule that have been substituted with hydroxypropyl groups. HPMC with a higher DS tends to be more hydrophilic and has a greater thickening effect.
  • Do not use 2 doses at the same time or extra doses.

  • No data are available concerning the ADME of modified celluloses in the target animal species. However, the absence of significant metabolism in the rat and the human indicates that, despite an increase of water solubility, the etherification of cellulose would strongly limit the action of microbial cellulases. Consequently, the FEEDAP Panel considers that the lack of digestibility of these compounds in monogastric mammals, poultry and fish is likely to occur. In ruminants and hindgut animals (rabbit and horse), it cannot be excluded that the rich and complex microbiota would allow a limited enzymatic attack of these structures.

  • As the pharmaceutical industry evolves, the demand for sophisticated dosage forms continues to rise. With China's expertise in manufacturing HPMCP powder, the future promises more efficient delivery systems that can improve patient compliance and therapeutic outcomes. The ongoing research and development efforts focused on this excipient are set to expand its role in advanced drug delivery technologies, shaping the landscape of modern medicine.
  • Hydroxypropyl methylcellulose (HPMC) is a versatile polymer that is used in a wide range of industries including pharmaceuticals, construction, and personal care products. It is commonly referred to as HPMC and has a unique HS code that is used for classifying and tracking the import and export of this material.
  • In the pharmaceutical industry, HEC is used as a binder in tablets and as a thickening agent in oral suspensions. The concentration of HEC in these formulations is carefully controlled to ensure proper viscosity for ease of administration and optimal drug delivery

  • In the personal care industry, HPMC is used as a thickener and emulsifier in creams, lotions, and shampoos. It helps to create a smooth and creamy texture while also providing excellent stability to the product. HPMC is also used in the production of hair care products, where it helps to condition and protect the hair.

  • 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.

    Lediglich bei der Einnahme sehr hoher Mengen kann eine abführende Wirkung eintreffen.

  • As soon as a product is labeled as vegetarian or vegan, consumers immediately get the impression that there’s something inherently good or natural about it, or that it’s somehow better for their health. However, the recent discussions about vegetarian meat substitutes have shown that this is not necessarily true. Such is the case for HPMC hard capsules. They’re vegan, made from cellulose fiber and therefore regarded as natural.

  • HPMC is a semi-synthetic polymer derived from cellulose, which is known for its ability to form hydrogels under certain conditions. It consists of a linear chain of glucose units connected by ether linkages, with hydroxypropyl and methyl groups attached to some of the hydroxyl groups along the chain. These substituents impart unique physical and chemical properties to HPMC, including its solubility in various solvents.
  • In the cosmetic industry, hydroxy methyl cellulose is used in a variety of products, including lotions, creams, and hair care products. HMC is valued for its ability to form a film on the skin or hair, helping to protect and moisturize the surface and improve the overall appearance and feel. HMC is also used as a thickener and stabilizer in these products, helping to create a smooth and creamy texture that is easy to apply and spread.
  • Hydroxypropyl methyl cellulose (HPMC) is a versatile and widely used modified cellulose derivative. It is derived from the natural polymer cellulose, which is abundant in plant cell walls. By substituting some of the hydroxyl groups on the glucose units of cellulose with methoxy and hydroxypropyl groups, HPMC is created. This modification imparts unique properties to the compound, making it valuable in various industries.
  • Secondly, HPMC exhibits pseudoplastic behavior, meaning its viscosity decreases with increasing shear rate. This property allows it to flow smoothly during processing while maintaining its thickening properties, which is beneficial in paints, adhesives, and other coating applications.
