  • HPMC is considered safe for human consumption. As HPMC is excreted undigested by the body like a water-soluble dietary fiber, it can be consumed without concern or restriction. Normally there is a so-called ADI value (acceptable daily intake) for the tolerability of food additives. This value indicates the daily dose that is considered medically safe for a lifelong daily intake. The ADI value is set by the German Federal Institute for Risk Assessment and the European Food Safety Authority (EFSA). There is no restriction on the maximum quantity for HPMC, i.e. no ADI value.

    A laxative effect may only occur if very high quantities are ingested.

  • HPMC, which stands for Hydroxypropyl Methylcellulose, is a widely used chemical compound with a diverse range of applications across various industries. It is a type of cellulose ether, derived from natural cellulose, a primary structural component found in plant cell walls. The production of HPMC involves two main raw materials cellulose and two chemical modifiers - hydroxypropyl and methyl groups. The primary source of cellulose is typically cotton lint or wood pulp, both rich sources of this naturally occurring polymer. These raw materials undergo a series of chemical processes to create HPMC. Firstly, the cellulose is treated with alkali, usually sodium hydroxide, to create a cellulose alkali solution. This step, known as alkalization, makes the cellulose more reactive. Next, the alkali cellulose is reacted with a propylene oxide and methylation agent, typically in the presence of a solvent like acetone or ethyl alcohol. Propylene oxide adds hydroxypropyl groups to the cellulose structure, while methylation is achieved through the action of methyl chloride. These modifications alter the properties of cellulose, imparting it with water-solubility and other desirable characteristics These modifications alter the properties of cellulose, imparting it with water-solubility and other desirable characteristics
