Comparing E460I - Microcrystalline cellulose vs E553A - synthetic magnesium silicates

Overview

E460I - Microcrystalline cellulose

Microcrystalline cellulose (E460i) is a purified, plant-based form of cellulose used to build texture, keep mixtures stable, and carry other ingredients. It is not digested by the body and works like dietary fiber in foods. It is common in many everyday products, from baked goods to sauces.

E553A - synthetic magnesium silicates

Synthetic magnesium silicates (E553a) are mineral-based powders used mainly to keep foods free-flowing and to stop sticky products from clumping. They are made by reacting magnesium salts with soluble silicates to produce a porous, water‑insoluble material that behaves like a tiny sponge. Regulators in the EU set detailed purity criteria for food‑grade E553a and list where it can be used in foods.

Popular questions

  1. Is microcrystalline cellulose safe?

    Yes—regulators such as the FDA (GRAS) and EFSA (ADI “not specified”) consider E460(i) safe at typical food-use levels. Because it isn’t digested, very high intakes may cause gas or laxative effects in some people.

  2. Is microcrystalline cellulose bad for you?

    No—it's an inert, non-digestible dietary fiber with very low toxicity. Potential issues are generally limited to bloating or stool changes if consumed in large amounts.

  3. What is microcrystalline cellulose made from?

    It’s purified, partially depolymerized cellulose made by acid hydrolysis of alpha-cellulose from plant sources such as wood pulp or cotton.

  4. Is microcrystalline cellulose gluten free?

    Yes—it's naturally gluten-free since it’s pure plant cellulose and contains no wheat, barley, or rye proteins.

  5. Is microcrystalline cellulose safe for dogs?

    Yes—it's commonly used as a fiber/binder in dog foods and is considered safe at typical levels. Excessive amounts may cause stool changes or GI upset, so check with a veterinarian for pets with digestive issues.
