Science
Mechanism of Action
This ingredient forms a cohesive film across the skin's surface, acting as a physical barrier. As a derivative of linseed oil, it inherently contains a spectrum of polyunsaturated and monounsaturated fatty acids (PUFA and MUFA). These fatty acids are recognized for their role in enhancing skin hydration, supporting barrier repair mechanisms, and potentially modulating inflammatory responses. Linseed oil, for instance, is noted for its omega-3 fatty acids that moisturize and may help regulate excess sebum production.

Stability
Polymerized Linseed Oil contains unsaturated esters prone to polymerization upon exposure to atmospheric oxygen. Its inherent high iodine and peroxide values indicate a limited oxidative stability, suggesting careful handling and formulation to prevent degradation.
Safety
Safety Profile
While a direct CIR assessment for 'POLY(LINSEED OIL)' specifically was not identified, INCI Beauty indicates 'No penalty' across all safety categories, suggesting a favorable profile in cosmetics. The broader category of polyglyceryl fatty acid esters, which may encompass similar derivatives, has been deemed 'safe as used' by the CIR Expert Panel when formulated to be non-irritating. Furthermore, Polymerized Linseed Oil is considered safe for food-contact surfaces by the FDA under specific conditions.
