FERROCENYLMETHYL METHACRYLATE/METHACRYLIC ACID COPOLYMER.

Insufficient Data / SKIN CONDITIONING, UV FILTER

This unique copolymer, featuring a ferrocenylmethyl component, functions primarily as a film-forming and pH-responsive agent in skincare. It is engineered for controlled ingredient release and offers potential UV filtration and redox properties.

Science

Mechanism of Action

FERROCENYLMETHYL METHACRYLATE/METHACRYLIC ACID COPOLYMER acts as a sophisticated film-former, creating a breathable barrier on the skin. Its methacrylic acid component renders it pH-responsive, typically dissolving at alkaline pH (above 5.5) and remaining insoluble in acidic environments, enabling precise, controlled release of active ingredients. The distinctive ferrocenylmethyl moiety also suggests potential redox capabilities, alongside its documented role as a UV filter.

Stability

This copolymer is generally soluble in water at alkaline pH, with dissolution observed above pH 5.5. Nanoparticle formulations stabilized by similar methacrylate-based anionic copolymers demonstrate stability across a broad pH range from 4.5 to 12.0. Certain forms can be miscible with water at any ratio, allowing versatility in both aqueous and organic solvent systems.

Safety Profile

CIR Status
Safe with restrictions
Max tested
25%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has broadly deemed 'Acrylates Copolymers' safe for cosmetic use up to 25% concentration, provided they are formulated to be non-irritating. However, FERROCENYLMETHYL METHACRYLATE/METHACRYLIC ACID COPOLYMER itself lacks an individual safety rating from CIR or SCCS. It is important to note that its monomer, Methacrylic Acid, is associated with moderate concerns for allergies and immunotoxicity according to EWG, necessitating careful consideration in formulation.
