    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.

    The mechanism of action for liquid thickeners can vary. Starches typically undergo gelatinization, a process where heat and water transform the granular starch into a viscous gel. This is why starch-based thickeners are often added to cold liquids and then heated to achieve the desired thickness. Gums, on the other hand, thicken liquids via hydration, soaking up water and swelling in size to create a thicker consistency. This property allows gums to be used in sauces and dressings without the need for cooking, making them versatile in both hot and cold applications.
