What it is and what it does

Cellulose

About this ingredient: EU CosIng ingredient registry (via Open Beauty Facts taxonomy) ↗

Absorbent: Takes up dispersed or dissolved material, including water or oils.
Anticaking: Keeps powder particles from clumping together.
Bulking: Changes a product's bulk density.
Emulsion stabilising: Helps keep an emulsion from separating.
Opacifying: Makes a product less transparent.
Stabilising: Helps maintain the stability of ingredients or the finished formula.
Viscosity controlling: Adjusts how thick or fluid a product is.

Function definitions: European Commission ingredient function definitions (SCCNFP/0299/00, pages 16 to 20) ↗

Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.

A closer look

What the research shows

Safety assessment

The expert panel accepted the described cosmetic uses of the listed cellulose ingredients.

What this does not tell us

Published safety assessment, not an efficacy trial. Its conclusion is limited to the reported cosmetic uses and concentrations, and relies partly on group read-across where individual data are missing. It does not establish current regulatory status or guarantee tolerance for every formulation. Final expert report; journal publication not verified. Indexed source establishes identity and final status; some safety support uses group read-across.
