Thickener and film-former.

What does Hypromellose do for skin?

Hypromellose (Hydroxypropyl Methylcellulose, HPMC) functions primarily as a film-former, viscosity-increasing agent, binder, and emulsion stabilizer in cosmetic formulations. Upon application, it forms a clear, flexible film on the skin or hair surface, contributing to a smoother feel, improved spreadability, and potential for transepidermal water loss reduction through an occlusive effect. In aqueous solutions, HPMC creates a polymeric network that increases viscosity, enabling the stabilization of emulsions and the suspension of insoluble particles, thereby enhancing product texture and stability.

Typical concentration: 0.1-5% (most formulas use 0.5-2%)

Is Hypromellose safe?

The Cosmetic Ingredient Review (CIR) Expert Panel assessed Hypromellose (as part of cellulose and its derivatives) and concluded it is safe as a cosmetic ingredient. It is generally considered non-irritating and non-sensitizing for topical use.
