Microcrystalline Cellulose
Cas No:9004-34-6



Cellulose is an important component of the cell walls of green plants and it's the most abundant natural polymer (big molecule from repeated subunits) on Earth. If the polymer structure is not too big (less than 200 repeated units), cellulose becomes microcrystalline cellulose.

In skin care, it comes as a fine or less fine white powder. The less fine (bigger particle size) version is used as a gentle scrubbing agent (a nice natural, biodegradable alternative to now banned plastic polyethylene) and the ultra fine version is used as a helper ingredient that gives a super-silky, soft touch, reduces tackiness or greasiness and can also be used as a mattifying agent.

* Defined as the isolated, colloidal crystalline portion of cellulose fibers
* Can be plant derived (sometimes through “upcycling” agricultural waste) or created synthetically
* Works in a variety of roles including absorbent, emulsion stabilizer, scrub and texture enhancer
* Also offers minor antioxidant properties (variable depending on the source)

Microcrystalline cellulose plays a variety of roles in cosmetic formulations including as an abrasive, absorbent, emulsion stabilizer, slip modifier and viscosity-increasing agent. It is defined as the isolated, colloidal crystalline portion of cellulose fibers, which can be plant derived or created synthetically.

In certain instances, microcrystalline cellulose is considered an “upcycled ingredient” because it can be created as a by-product of the waste from agricultural industries, including banana, corn, sugarcane, and soybean farming. It can also be extracted from oil palm fibers.

Researchers also note microcrystalline cellulose offers antioxidant properties and can help improve formulary shelf life. The strength of antioxidant power depends on the source and method of preparation.

Microcrystalline cellulose has been deemed safe by the Cosmetic Ingredient Review, with reported concentrations of use ranging from 0.0001 to 57%.
