Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose (HPMC) is a chemically modified cellulose, a natural polymer found in plant cell walls. It is made by treating cellulose with methyl chloride and propylene oxide.

HPMC is used as a thickener, emulsifier, and stabilizer in foods. It helps improve texture and prevent ingredients from separating. It is often found in baked goods, sauces, dressings, and dairy alternatives.

In the United States, HPMC is generally recognized as safe (GRAS) by the FDA for use as a food additive. Regulatory bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated HPMC. At typical consumption levels, it is not associated with adverse health effects. Some research suggests it may act as a dietary fiber, potentially aiding digestion.
