Science
Mechanism of Action
As a primary film-forming agent, Nitrocellulose deposits a transparent, continuous film upon application, which adheres effectively to surfaces. This film creates a physical barrier, aiding in protection or controlling the release of other compounds by forming a stable matrix. It also functions as a binder, improving product cohesion, and a non-surfactant dispersing agent within formulations.

Stability
Nitrocellulose is non-volatile but can decompose when exposed to UV light or temperatures above 100°C. Dry forms are sensitive to heat and impact, necessitating storage in a damped state within tightly sealed containers.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed nitrocellulose safe for use in cosmetics at concentrations up to 22%. Its high molecular weight suggests negligible dermal absorption. Animal studies found no evidence of toxicity, carcinogenicity, reproductive/developmental toxicity, mutagenicity, or genotoxicity. Human patch tests with nail formulations containing 8.85% and 10.5% nitrocellulose confirmed no primary irritation or sensitization.
