Science
Mechanism of Action
This ingredient functions by mechanically removing dead skin cells from the skin surface, promoting a smoother complexion. Its inherent absorbent capabilities effectively capture excess sebum, leading to a reduction in surface shine and oil buildup. Furthermore, it acts as a bulking agent, texturizer, and emulsion stabilizer, enhancing the spreadability, consistency, and overall stability of cosmetic products.

The Formula
Formulation
Stability
Microcrystalline Cellulose is chemically inert, exhibiting stability across a broad pH range, making it suitable for both acidic and basic formulations. While practically insoluble in most solvents, it demonstrates the ability to swell in water. Its hygroscopic nature necessitates consideration in formulations with moisture-sensitive active ingredients.
Conflicts
- highly hygroscopic drugs (due to potential moisture retention and physical interaction)
- acidic APIs (may reduce compatibility and alter drug release profiles)
- strongly acidic drugs (potential for hydrolysis of glycosidic bonds under extreme conditions)
Safety
Safety Profile
The CIR Expert Panel has deemed Microcrystalline Cellulose safe for cosmetic use. Extensive ocular and dermal irritation studies confirm it is non-irritating to slightly irritating, and importantly, non-sensitizing and non-photosensitizing at concentrations reaching up to 100%. The FDA also recognizes it as Generally Recognized As Safe (GRAS).
