Background: Biopolymer-based active packaging has experienced significant growth in the food industry due to its capacity to enhance product stability and reduce reliance on synthetic preservatives. However, its application in cosmetics remains limited, despite increasing consumer demand for sustainable and preservative-free solutions. Objective: This review evaluates the feasibility of transferring biopolymer-based active packaging technologies from the food sector to cosmetic applications, identifying relevant materials, processing methods, and implementation challenges. Methodology: A bibliographic search was conducted across nine databases (2000–2025) using the keywords “active packaging,” “antioxidant,” “antimicrobial,” and “biopolymers.” Results: The most recurrent biopolymers identified were chitosan, fish gelatin, zein, and kafirin, all of which exhibit biodegradability, film-forming capacity, and compatibility with natural additives. Although their intrinsic antioxidant and antimicrobial properties are limited, these can be enhanced through the incorporation of bioactive compounds. Processing techniques such as casting, coating, dry forming, and electrospinning were found to be the most effective, enabling customized packaging designs. Key challenges include cost, sensory attributes, mechanical limitations, and regulatory compliance. Conclusion: Active packaging systems based on biopolymers—either alone or combined with natural bioactive ingredients—offer a viable innovation pathway for the cosmetics industry. These systems support clean-label claims and ecological positioning, representing a strategic opportunity to adapt validated technologies from the food sector to meet emerging cosmetic market demands.

Background/Objectives: The rational design of modified-release matrix tablets requires a thorough understanding of granulometric analysis, compaction behavior, and drug release profile. In this study, we evaluated the physicochemical, granulometric, and mechanical properties of hydroxypropyl methylcellulose, polyethylene oxide, and ethylcellulose in galantamine matrix formulations. Methods: Spectroscopic (FTIR) and thermal (DSC) analyses demonstrated drug–polymer compatibility. We assessed flowability, cohesion, and aeration behavior through granulometric analysis and applied compressibility models (Kawakita, Heckel, Leuenberger) to characterize deformation mechanisms. Results: Hydroxypropyl methylcellulose showed superior compactability (T_max = 4.61 MPa) and sustained drug release (85.4% at 12 h, DE% = 62.2%), while polyethylene oxide enabled gradual erosion and consistent delivery (88.7% at 12 h, DE% = 57.5%). In contrast, ethylcellulose exhibited high cohesiveness but poor matrix integrity, leading to premature drug release (76.6% at 1 h, DE% = 73.7%). Only hydroxypropyl methylcellulose and polyethylene oxide formulations met USP criteria. Conclusions: These results demonstrate that polymer selection critically influences powder behavior and matrix performance, underscoring the need for integrated granulometric and mechanical evaluation in the development of robust controlled-release systems.

Polyphenolic antioxidants are incorporated into pharmaceutical, dermopharmaceutical, and cosmetic products because of their capacity to modulate oxidative stress, inflammation, microbial imbalance, skin aging, wound repair, and tumor-related processes. However, formulation is constrained by chemical instability, limited bioavailability, insufficient skin permeation, and degradation during processing or storage. This review integrates the chemical characteristics, natural sources, extraction approaches, antioxidant mechanisms, and evaluation of curcumin and chlorogenic acid, and critically examines their delivery through liposomes, niosomes, ethosomes, and transethosomes. Curcumin is lipophilic and poorly water-soluble, whereas chlorogenic acid is hydrophilic but permeability-limited. Their antioxidant activity is discussed through hydrogen atom transfer, single-electron transfer, interruption of lipid peroxidation, metal chelation, and localization within lipid interfaces, together with chemical, biomimetic, and cellular assessment methods. Vesicular carriers can improve encapsulation, stability, release control, skin interaction, biological performance, and incorporation into semisolid dosage forms. However, these benefits are accompanied by formulation-dependent trade-offs involving manufacturing complexity and cost, long-term stability and reproducibility, excipient-related skin tolerability, scale-up, and an application scope that depends on the intended dermal-delivery endpoint. Therefore, efficacy depends on the interplay among antioxidant properties, vesicle architecture, excipient selection, and processing conditions. Curcumin-loaded vesicles are better documented than chlorogenic-acid-loaded systems, particularly for deformable carriers. Future progress requires quality-by-design strategies, standardized characterization, predictive skin models, long-term stability and safety studies, and scalable manufacturing. Overall, antioxidant-loaded vesicles represent multifunctional platforms for developing stable and effective pharmaceutical and cosmetic products.
