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.
One common concern is that it is found in non-food products - paint, eye drops, medicine (again, as a stabiliser). For the record, so is water. Like water, HPMC's existence in non-food products doesn't automatically discount it from being used in perfectly safe, edible products. Crucially, it has been approved as a food additive by both the EU and the FDA.
