How long will hydrxypropyl methyl cellulose stay in your system?

Hydroxypropyl methyl cellulose (HPMC) is a non-toxic, water-soluble polymer commonly used as a thickening agent, emulsifier, or film-former in various products. It is not significantly absorbed in the gastrointestinal tract, so it typically passes through the body without being metabolized. Consequently, HPMC does not accumulate in the system and is generally eliminated within a day or two after ingestion, depending on individual digestive transit times.
