Science
Mechanism of Action
This hydrolyzed copolymer primarily functions as a film-forming agent, depositing a fine, protective layer on the skin's surface. This barrier effectively reduces moisture evaporation, thereby enhancing skin hydration and contributing to a smoother, refined texture. As an amphiphilic compound, it possesses the capability to self-assemble into micellar structures within aqueous solutions, facilitating emulsification and potentially enabling controlled release mechanisms for co-formulated actives.

Stability
The hydrolyzed form (ethylene-maleic acid sodium salt) demonstrates excellent water solubility, forming clear and stable solutions. While the polymer maintains structural integrity across a broad pH spectrum, notably between pH 5.5 and 8.5, its functional performance, particularly in controlled release from nanoemulsions, is pH-responsive, exhibiting accelerated release rates in mildly acidic (pH 5.5) or mildly alkaline (pH 8.5) conditions compared to neutral (pH 7.0).
Safety
Safety Profile
Although direct CIR status for HYDROLYZED ETHYLENE/MA COPOLYMER is not explicitly identified, closely related copolymers, such as PVM/MA Copolymer, have been affirmed as safe for cosmetic use by the CIR Expert Panel. Large copolymers are generally recognized for their low toxicity. The ingredient itself is commonly regarded as safe and non-toxic, with various safety references, including FDA listings for indirect food contact. As with any new cosmetic ingredient, routine patch testing is advised.
