Science
Mechanism of Action
This sophisticated copolymer functions by creating an ultra-thin, continuous film upon application to the skin. This film demonstrates an optimal balance of cohesion and adhesion, effectively forming a protective barrier that limits the penetration of exogenous substances into the stratum corneum. Concurrently, it measurably reduces transepidermal water loss (TEWL), thereby boosting skin moisturization. Furthermore, its film-forming properties enhance the durability and spreadability of cosmetic formulations, contributing to improved makeup longevity and overall product performance.

Stability
Similar acrylic copolymer emulsions exhibit stability across all pH ranges and provide significant water resistance, making them ideal for long-wearing and transfer-resistant cosmetic formulations. They are also shown to be compatible with both natural and synthetic water-soluble polymers, offering versatility in product development.

Safety
Safety Profile
This high molecular weight polymer demonstrates poor absorption into the skin or scalp, supporting its safe use in cosmetic formulations. The Cosmetic Ingredient Review (CIR) Expert Panel has deemed it safe as used, drawing parallels with the established safety of polymethyl methacrylate (PMMA) in medical applications. Related acrylates copolymers, including those derived from methyl, ethyl, propyl, or butyl esters of acrylic and methacrylic acid, have also been assessed by the CIR and found safe as used. Stringent manufacturing processes ensure residual monomer levels are precisely controlled, typically to low parts per million (ppm).
