Hydroxypropyl MethylCellulose E464

Hydroxypropyl Methylcellulose (HPMC) is a semi-synthetic polymer derived from cellulose. It is commonly used in the food industry as a food additive with the E number E464.

HPMC is made by treating cellulose with a combination of alkali and etherification agents, which results in the substitution of some of the hydroxyl groups on the cellulose molecule with hydroxypropyl and methyl groups. The degree of substitution determines the properties of the resulting HPMC, such as its solubility and gelation properties.

In food, HPMC is used as a thickener, emulsifier, and stabilizer, among other functions. It can be used to improve the texture of food products such as sauces, dressings, and baked goods. HPMC is also used as a coating for tablets and capsules in the pharmaceutical industry, as well as in the production of personal care and cosmetic products.

HPMC is generally considered safe for consumption and has been approved for use in food by many regulatory agencies around the world, including the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, as with all food additives, it is important to use HPMC in accordance with recommended levels and regulations to ensure its safety.
