What it is
Cellulose is a natural polymer made of linked glucose units and is the main structural component of plant cell walls. In formulas it is used as a fine, insoluble powder to add body, control flow, and absorb excess oil, which can soften shine and improve spreadability. In sunscreens it can contribute to a smooth, dry-touch finish and help with even application.
Safety & warnings
Cellulose is inert, non-irritating for most users, and not associated with sensitization or fragrance allergy. As an insoluble powder it is not considered comedogenic in typical use.
Origin & sourcing
It is naturally sourced, most often purified from wood pulp or cotton, and is one of the most abundant plant-derived polymers.
