What is it?
Cellulose (C6H10O5)n is refined wood pulp. It is a white, free-flowing powder. Chemically, it is an inert substance, is not degraded during digestion and has no appreciable absorption. In large quantities it provides dietary bulk and may lead to a laxative effect.
Microcrystalline cellulose is a commonly used excipient in the pharmaceutical industry. It has excellent compressibility properties and is used in solid dose forms, such as tablets. Tablets can be formed that are hard, but dissolve quickly. Microcrystalline cellulose is the same as cellulose, except that it meets USP standards.[1]
It is also found in many processed food products, and may be used as an anti-caking agent, stabilizer, texture modifier, packaging component, or suspending agent among other uses. According to the Select Committee on GRAS Substances, cellulose acetate is generally regarded as safe when used in normal quantities. [2][3][4]
