What is HPMC?
Although relatively rare, some individuals may experience allergic reactions to HPMC. Symptoms of an allergy could include rashes, itchiness, hives, or respiratory issues. If any signs of an allergic reaction occur after consuming or using a product containing hydroxypropyl methylcellulose, it is crucial to seek medical attention immediately. Conducting a patch test before using new cosmetic products that contain HPMC can also be a prudent approach for individuals with known sensitivities.
In the food industry, HPMC is often employed as a food additive due to its excellent emulsifying and stabilizing properties. Here, the density of HPMC affects the texture and mouthfeel of food products. For instance, in gluten-free bakery items, HPMC can enhance dough structure, improving loaf volume and crumb texture. The specific density of HPMC blends can influence how they interact with other components in the formulation, thereby impacting the overall sensory qualities of the final product.
In the pharmaceutical industry, HPMC is frequently employed in drug formulations, particularly in controlled-release and sustained-release systems. Its role in capsule production, as an excipient, is critical for ensuring consistent drug release rates. Regulatory agencies, including the U.S. Food and Drug Administration (FDA), recognize HPMC as Generally Recognized As Safe (GRAS) for use in food and pharmaceuticals. Research supporting its safety includes studies demonstrating low toxicity levels and minimal side effects.

Is it safe?: In an FDA study with rats, there were no significant toxic effects other than growth retardation once HPMC reached levels of 20 to 30% of the rats’ diet. This study noted that growth retardation may be contributed to malnutrition and not the amount of HPMC. In another study, rabbits were injected with 2% HPMC for over a month and there were no observations of toxicity or irritation. Overall, the FDA sees it as a non-toxic and non-irritating inactive ingredient that is safe for human use and consumption.
