Science
Mechanism of Action
The copolymer's mechanism involves establishing a highly substantive, breathable film on the stratum corneum, concurrently acting as a humectant to sequester atmospheric moisture and an emollient to optimize intercellular lipid organization. The ricinoleic acid moiety, a C-18 unsaturated fatty acid, facilitates deep transdermal penetration, thereby augmenting intrinsic moisture retention and delivering adjunctive anti-inflammatory and broad-spectrum antibacterial effects. This synergistic action collectively contributes to a more resilient, hydrated, and visually refined epidermal surface.

Stability
The polymerization process integral to this copolymer dramatically enhances the oxidative stability of its ricinoleic acid component, effectively mitigating the risk of rancidity upon atmospheric oxygen exposure. Furthermore, the resulting poly(ricinoleic acid) derivatives exhibit commendable thermal resilience, ensuring product integrity across diverse temperature ranges.
Safety
Safety Profile
While RICINOLEIC ACID/ADIPIC ACID/AEEA COPOLYMER has not undergone an explicit review by the Cosmetic Ingredient Review (CIR) Expert Panel, its foundational constituents, Ricinus Communis (Castor) Seed Oil and various Ricinoleates, have been affirmed as safe for cosmetic applications. Further supporting its safety profile, a chemically similar polymer incorporating adipic acid received an FDA tolerance exemption, categorized as a low-risk polymer due to negligible absorption through intact skin or the gastrointestinal tract, thereby suggesting minimal systemic exposure concerns.
